There are example Flutter app inside the example directory. In there you can check how the Adjust SDK can be integrated.
These are the minimal steps required to integrate the Adjust SDK into your Flutter app.
You can add Adjust SDK to your Flutter app by adding following to your pubspec.yaml file:
dependencies:
adjust_sdk: ^4.17.0Then navigate to your project in the terminal and run:
flutter packages get
Note: If you are using Visual Studio Code to develop your app, upon editing pubspec.yaml, it will automatically run this command, so you don't need to run it manually.
Since the 1st of August of 2014, apps in the Google Play Store must use the Google Advertising ID to uniquely identify devices. To allow the Adjust SDK to use the Google Advertising ID, you must integrate the Google Play Services. If you haven't done this yet, please add dependency to Google Play Services library by adding following dependecy to your dependencies block of app's build.gradle file for Android platform:
implementation 'com.google.android.gms:play-services-analytics:16.0.4'Note: The Adjust SDK is not tied to any specific version of the play-services-analytics part of the Google Play Services library, so feel free to always use the latest version of it (or whichever you might need).
Please add the following permissions, which the Adjust SDK needs, if they are not already present in your AndroidManifest.xml file for Android platform:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>If you are not targeting the Google Play Store, please also add the following permission:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>If you are using Proguard, add these lines to your Proguard file:
-keep public class com.adjust.sdk.** { *; }
-keep class com.google.android.gms.common.ConnectionResult {
int SUCCESS;
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient {
com.google.android.gms.ads.identifier.AdvertisingIdClient$Info getAdvertisingIdInfo(android.content.Context);
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient$Info {
java.lang.String getId();
boolean isLimitAdTrackingEnabled();
}
-keep public class com.android.installreferrer.** { *; }
If you are not publishing your app in the Google Play Store, you can leave just com.adjust.sdk package rules:
-keep public class com.adjust.sdk.** { *; }
In order to correctly attribute an install of your app to its source, Adjust needs information about the install referrer. This can be obtained by using the Google Play Referrer API or by catching the Google Play Store intent with a broadcast receiver.
Important: The Google Play Referrer API is newly introduced by Google with the express purpose of providing a more reliable and secure way of obtaining install referrer information and to aid attribution providers in the fight against click injection. It is strongly advised that you support this in your application. The Google Play Store intent is a less secure way of obtaining install referrer information. It will continue to exist in parallel with the new Google Play Referrer API temporarily, but it is set to be deprecated in future.
In order to support this in your app, please make sure to add following dependency to your app's build.gradle file for Android platform:
implementation 'com.android.installreferrer:installreferrer:1.0'
Also, make sure that you have paid attention to the Proguard settings chapter and that you have added all the rules mentioned in it, especially the one needed for this feature:
-keep public class com.android.installreferrer.** { *; }
The Google Play Store INSTALL_REFERRER intent should be captured with a broadcast receiver. If you are not using your own broadcast receiver to receive the INSTALL_REFERRER intent, add the following receiver tag inside the application tag in your AndroidManifest.xml file for Android platform.
<receiver
android:name="com.adjust.sdk.AdjustReferrerReceiver"
android:permission="android.permission.INSTALL_PACKAGES"
android:exported="true" >
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>We use this broadcast receiver to retrieve the install referrer and pass it to our backend.
If you are already using a different broadcast receiver for the INSTALL_REFERRER intent, follow these instructions to add the Adjust broadcast receiver.
To start with, we'll set up basic session tracking.
Make sure to initialise Adjust SDK as soon as possible in your Flutter app (upon loading first widget in your app). You can initialise Adjust SDK like described below:
AdjustConfig config = new AdjustConfig('{YourAppToken}', AdjustEnvironment.sandbox);
Adjust.start(config);Replace {YourAppToken} with your app token. You can find this in your dashboard.
Depending on whether you are building your app for testing or for production, you must set environment with one of these values:
AdjustEnvironment.sandbox;
AdjustEnvironment.production;Important: This value should be set to AdjustEnvironment.sandbox if and only if you or someone else is testing your app. Make sure to set the environment to AdjustEnvironment.production before you publish the app. Set it back to AdjustEnvironment.sandbox when you start developing and testing it again.
We use this environment to distinguish between real traffic and test traffic from test devices. It is imperative that you keep this value meaningful at all times!
Note: This step is really important and please make sure that you implement it properly in your app. By implementing it, you will enable proper session tracking by the Adjust SDK in your app.
Session tracking for iOS platform is supported out of the box, but in order to perform it properly on Android platform, it requires a bit of additional work described in chapter below.
On Android platform, it is important for you to hook up into app activity lifecycle methods and make a call to Adjust.onResume() when ever app enters foreground and a call to Adjust.onPause() when ever app leaves foreground. You can do this globally or per widget (call these method upon each transition from one widget to another). For example:
class AdjustExampleApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Adjust Flutter Example App',
home: new MainScreen(),
);
}
}
class MainScreen extends StatefulWidget {
@override
State createState() => new MainScreenState();
}
class MainScreenState extends State<MainScreen> with WidgetsBindingObserver {
@override
initState() {
super.initState();
WidgetsBinding.instance.addObserver(this);
initPlatformState(); // <-- Initialise SDK in here.
}
@override
void dispose() {
WidgetsBinding.instance.removeObserver(this);
super.dispose();
}
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
setState(() {
switch (state) {
case AppLifecycleState.inactive:
break;
case AppLifecycleState.resumed:
Adjust.onResume();
break;
case AppLifecycleState.paused:
Adjust.onPause();
break;
case AppLifecycleState.suspending:
break;
}
});
}
}An account manager must activate the Adjust SDK signature. Contact Adjust support ([email protected]) if you are interested in using this feature.
If the SDK signature has already been enabled on your account and you have access to App Secrets in your Adjust Dashboard, please use the method below to integrate the SDK signature into your app.
An App Secret is set by calling setAppSecret on your config instance:
AdjustConfig adjustConfig = new AdjustConfig(yourAppToken, environment);
adjustConfig.setAppSecret(secretId, info1, info2, info3, info4);
Adjust.start(adjustConfig);You can increase or decrease the amount of logs that you see during testing by setting logLevel member on your config instance with one of the following parameters:
adjustConfig.logLevel = AdjustLogLevel.verbose; // enable all logs
adjustConfig.logLevel = AdjustLogLevel.debug; // disable verbose logs
adjustConfig.logLevel = AdjustLogLevel.info; // disable debug logs (default)
adjustConfig.logLevel = AdjustLogLevel.warn; // disable info logs
adjustConfig.logLevel = AdjustLogLevel.error; // disable warning logs
adjustConfig.logLevel = AdjustLogLevel.suppress; // disable all logsBuild and run your Flutter app. In your Android/iOS log you can check for logs coming from Adjust SDK and in there you should see message: Install tracked.
If you are using an Adjust tracker URL with the option to deep link into your app, there is the possibility to get information about the deep link URL and its content. Hitting the URL can happen when the user has your app already installed (standard deep linking scenario) or if they don't have the app on their device (deferred deep linking scenario). In the standard deep linking scenario, the Android platform natively offers the possibility for you to get the information about the deep link content. The deferred deep linking scenario is something which the Android platform doesn't support out of the box, and, in this case, the Adjust SDK will offer you the mechanism you need to get the information about the deep link content.
You need to set up deep linking handling in your app on native level - in your generated Xcode project (for iOS) and Android Studio (for Android).
Unfortunately, in this scenario the information about the deep link can not be delivered to you in your Dart code. Once you enable your app to handle deep linking, you will get information about the deep link on native level. For more information check our chapters below on how to enable deep linking for Android and iOS apps.
In order to get information about the URL content in a deferred deep linking scenario, you should set a callback method on the config object which will receive one string parameter where the content of the URL will be delivered. You should set this method on the config object by assigning the deferredDeeplinkCallback member:
AdjustConfig adjustConfig = new AdjustConfig(yourAppToken, environment);
adjustConfig.deferredDeeplinkCallback = (String uri) {
print('[Adjust]: Received deferred deeplink: ' + uri);
};
Adjust.start(adjustConfig);In deferred deep linking scenario, there is one additional setting which can be set on the config object. Once the Adjust SDK gets the deferred deep link information, we offer you the possibility to choose whether our SDK should open this URL or not. You can choose to set this option by assigning the launchDeferredDeeplink member of the config instance:
AdjustConfig adjustConfig = new AdjustConfig(yourAppToken, environment);
adjustConfig.launchDeferredDeeplink = true;
adjustConfig.deferredDeeplinkCallback = (String uri) {
print('[Adjust]: Received deferred deeplink: ' + uri);
};
Adjust.start(adjustConfig);If nothing is set, the Adjust SDK will always try to launch the URL by default.
To enable your apps to support deep linking, you should set up schemes for each supported platform.
This should be done in native Android Studio / Eclipse project.
To set up your Android app to handle deep linking on native level, please follow our guide in the official Android SDK README.
This should be done in native Xcode project.
To set up your iOS app (Runner project) to handle deep linking on native level, please follow our guide in the official iOS SDK README.
Adjust enables you to run re-engagement campaigns through deep links. For more information on how to do that, please check our official docs.
If you are using this feature, in order for your user to be properly reattributed, you need to make one additional call to the Adjust SDK in your app.
Once you have received deep link content information in your app, add a call to the appWillOpenUrl method. By making this call, the Adjust SDK will try to find if there is any new attribution information inside of the deep link. If there is any, it will be sent to the Adjust backend. If your user should be reattributed due to a click on the adjust tracker URL with deep link content, you will see the attribution callback in your app being triggered with new attribution info for this user.
Once everything set up, inside of your native Android activity make a call to appWillOpenUrl method in following way:
import com.adjust.sdk.flutter.AdjustSdk;
public class MainActivity extends FlutterActivity {
// Either call make the call in onCreate.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
Intent intent = getIntent();
Uri data = intent.getData();
AdjustSdk.appWillOpenUrl(data);
}
// Or make the cakll in onNewIntent.
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Uri data = intent.getData();
AdjustSdk.appWillOpenUrl(data);
}
}Depending on the android:launchMode setting of your Activity in the AndroidManifest.xml file, information about the deep_link parameter content will be delivered to the appropriate place in the Activity file. For more information about the possible values of the android:launchMode property, check the official Android documentation.
There are two places within your desired Activity where information about the deep link content will be delivered via the Intent object - either in the Activity's onCreate or onNewIntent methods. Once your app has launched and one of these methods has been triggered, you will be able to get the actual deep link passed in the deep_link parameter in the click URL.
Once everything set up, inside of your native iOS app delegate make a call to appWillOpenUrl method in following way:
#import "Adjust.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[GeneratedPluginRegistrant registerWithRegistry:self];
// Override point for customization after application launch.
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
[Adjust appWillOpenUrl:url];
return YES;
}
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> *restorableObjects))restorationHandler {
if ([[userActivity activityType] isEqualToString:NSUserActivityTypeBrowsingWeb]) {
[Adjust appWillOpenUrl:[userActivity webpageURL]];
}
return YES;
}
@endYou can use adjust to track any event in your app. Suppose you want to track every tap on a button. You would have to create a new event token in your dashboard. Let's say that event token is abc123. In your button's click handler method you could then add the following lines to track the click:
AdjustEvent adjustEvent = new AdjustEvent('abc123');
Adjust.trackEvent(adjustEvent);If your users can generate revenue by tapping on advertisements or making in-app purchases you can track those revenues with events. Lets say a tap is worth one Euro cent. You could then track the revenue event like this:
AdjustEvent adjustEvent = new AdjustEvent('abc123');
adjustEvent.setRevenue(6, 'EUR');
Adjust.trackEvent(adjustEvent);This can be combined with callback parameters of course.
When you set a currency token, Adjust will automatically convert the incoming revenues into a reporting revenue of your choice. Read more about currency conversion here.
You can read more about revenue and event tracking in the event tracking guide.
You can also add an optional transaction ID to avoid tracking duplicated revenues. The last ten transaction IDs are remembered, and revenue events with duplicated transaction IDs are skipped. This is especially useful for In-App Purchase tracking. You can see an example below.
If you want to track in-app purchases, please make sure to call the trackEvent only if the transaction is finished and item is purchased. That way you can avoid tracking revenue that is not actually being generated.
AdjustEvent adjustEvent = new AdjustEvent('abc123');
adjustEvent.transactionId = '{TransactionId}';
Adjust.trackEvent(adjustEvent);In addition to the data points that Adjust SDK collects by default, you can use the Adjust SDK to track and add to the event/session as many custom values as you need (user IDs, product IDs, etc.). Custom parameters are only available as raw data (i.e., they won't appear in the Adjust dashboard).
You should use callback parameters for the values that you collect for your own internal use, and partner parameters for those that you wish to share with external partners. If a value (e.g. product ID) is tracked both for internal use and to forward it to external partners, the best practice would be to track it both as callback and partner parameters.
You can register a callback URL for your events in your dashboard. We will send a GET request to that URL whenever the event is tracked. You can add callback parameters to that event by calling addCallbackParameter to the event instance before tracking it. We will then append these parameters to your callback URL.
For example, suppose you have registered the URL http://www.adjust.com/callback then track an event like this:
AdjustEvent adjustEvent = new AdjustEvent('abc123');
adjustEvent.addCallbackParameter('key', 'value');
adjustEvent.addCallbackParameter('foo', 'bar');
Adjust.trackEvent(adjustEvent);In that case we would track the event and send a request to:
http://www.adjust.com/callback?key=value&foo=bar
It should be mentioned that we support a variety of placeholders like {gps_adid} that can be used as parameter values. In the resulting callback this placeholder would be replaced with the Google Play Services ID of the current device. Also note that we don't store any of your custom parameters, but only append them to your callbacks. If you haven't registered a callback for an event, these parameters won't even be read.
You can read more about using URL callbacks, including a full list of available values, in our callbacks guide.
You can also add parameters to be transmitted to network partners, which have been activated in your Adjust dashboard.
This works similarly to the callback parameters mentioned above, but can be added by calling the addPartnerParameter method on your event instance.
AdjustEvent adjustEvent = new AdjustEvent('abc123');
adjustEvent.addPartnerParameter('key', 'value');
adjustEvent.addPartnerParameter('foo', 'bar');
Adjust.trackEvent(adjustEvent);You can read more about special partners and these integrations in our guide to special partners.
You can also add custom string identifier to each event you want to track. This identifier will later be reported in event success and/or event failure callbacks to enable you to keep track on which event was successfully tracked or not. You can set this identifier by assigning the callbackId member of your event instance:
AdjustEvent adjustEvent = new AdjustEvent('abc123');
adjustEvent.callbackId = '{CallbackId}';
Adjust.trackEvent(adjustEvent);Some parameters are saved to be sent in every event and session of the Adjust SDK. Once you have added any of these parameters, you don't need to add them every time, since they will be saved locally. If you add the same parameter twice, there will be no effect.
These session parameters can be called before the Adjust SDK is launched to make sure they are sent even on install. If you need to send them with an install, but can only obtain the needed values after launch, it's possible to delay the first launch of the Adjust SDK to allow this behaviour.
The same callback parameters that are registered for events can be also saved to be sent in every event or session of the Adjust SDK.
The session callback parameters have a similar interface to the event callback parameters. Instead of adding the key and it's value to an event, it's added through a call to Adjust.addSessionCallbackParameter(String key, String value):
Adjust.addSessionCallbackParameter('foo', 'bar');The session callback parameters will be merged with the callback parameters added to an event. The callback parameters added to an event have precedence over the session callback parameters. Meaning that, when adding a callback parameter to an event with the same key to one added from the session, the value that prevails is the callback parameter added to the event.
It's possible to remove a specific session callback parameter by passing the desiring key to the method Adjust.removeSessionCallbackParameter(String key).
Adjust.removeSessionCallbackParameter('foo');If you wish to remove all keys and their corresponding values from the session callback parameters, you can reset it with the method Adjust.resetSessionCallbackParameters().
Adjust.resetSessionCallbackParameters();In the same way that there are session callback parameters sent in every event or session of the Adjust SDK, there is also session partner parameters.
These will be transmitted to network partners, for the integrations that have been activated in your Adjust dashboard.
The session partner parameters have a similar interface to the event partner parameters. Instead of adding the key and it's value to an event, it's added through a call to Adjust.addSessionPartnerParameter(String key, String value):
Adjust.addSessionPartnerParameter('foo', 'bar');The session partner parameters will be merged with the partner parameters added to an event. The partner parameters added to an event have precedence over the session partner parameters. Meaning that, when adding a partner parameter to an event with the same key to one added from the session, the value that prevails is the partner parameter added to the event.
It's possible to remove a specific session partner parameter by passing the desiring key to the method Adjust.removeSessionPartnerParameter(String key).
Adjust.removeSessionPartnerParameter('foo');If you wish to remove all keys and their corresponding values from the session partner parameters, you can reset it with the method Adjust.resetSessionPartnerParameters().
Adjust.resetSessionPartnerParameters();Delaying the start of the Adjust SDK allows your app some time to obtain session parameters, such as unique identifiers, to be sent on install.
Set the initial delay time in seconds with the delayStart member of the config instance:
adjustConfig.delayStart = 5.5;In this case, this will make the Adjust SDK not send the initial install session and any event created for 5.5 seconds. After this time is expired or if you call Adjust.sendFirstPackages() in the meanwhile, every session parameter will be added to the delayed install session and events and the Adjust SDK will resume as usual.
The maximum delay start time of the adjust SDK is 10 seconds.
Once you have integrated the Adjust SDK into your project, you can take advantage of the following features.
Push tokens are used for Audience Builder and client callbacks, and they are required for uninstall and reinstall tracking.
To send us the push notification token, add the following call to Adjust once you have obtained your token or when ever it's value is changed:
Adjust.setPushToken('{PushNotificationsToken}');You can register a callback to be notified of tracker attribution changes. Due to the different sources considered for attribution, this information can not be provided synchronously.
Please make sure to consider our applicable attribution data policies.
With the config instance, before starting the SDK, add the attribution callback:
AdjustConfig adjustConfig = new AdjustConfig(yourAppToken, environment);
config.attributionCallback = (AdjustAttribution attributionChangedData) {
print('[Adjust]: Attribution changed!');
if (attributionChangedData.trackerToken != null) {
print('[Adjust]: Tracker token: ' + attributionChangedData.trackerToken);
}
if (attributionChangedData.trackerName != null) {
print('[Adjust]: Tracker name: ' + attributionChangedData.trackerName);
}
if (attributionChangedData.campaign != null) {
print('[Adjust]: Campaign: ' + attributionChangedData.campaign);
}
if (attributionChangedData.network != null) {
print('[Adjust]: Network: ' + attributionChangedData.network);
}
if (attributionChangedData.creative != null) {
print('[Adjust]: Creative: ' + attributionChangedData.creative);
}
if (attributionChangedData.adgroup != null) {
print('[Adjust]: Adgroup: ' + attributionChangedData.adgroup);
}
if (attributionChangedData.clickLabel != null) {
print('[Adjust]: Click label: ' + attributionChangedData.clickLabel);
}
if (attributionChangedData.adid != null) {
print('[Adjust]: Adid: ' + attributionChangedData.adid);
}
};
Adjust.start(adjustConfig);The callback function will be called after the SDK receives the final attribution data. Within the callback function you have access to the attribution parameter. Here is a quick summary of its properties:
trackerTokenthe tracker token string of the current attribution.trackerNamethe tracker name string of the current attribution.networkthe network grouping level string of the current attribution.campaignthe campaign grouping level string of the current attribution.adgroupthe ad group grouping level string of the current attribution.creativethe creative grouping level string of the current attribution.clickLabelthe click label string of the current attribution.adidthe Adjust device identifier string.
You can register a callback to be notified when events or sessions are tracked. There are four callbacks: one for tracking successful events, one for tracking failed events, one for tracking successful sessions and one for tracking failed sessions. You can add any number of callbacks after creating the config object:
AdjustConfig adjustConfig = new AdjustConfig(yourAppToken, environment);
// Set session success tracking delegate.
config.sessionSuccessCallback = (AdjustSessionSuccess sessionSuccessData) {
print('[Adjust]: Session tracking success!');
if (sessionSuccessData.message != null) {
print('[Adjust]: Message: ' + sessionSuccessData.message);
}
if (sessionSuccessData.timestamp != null) {
print('[Adjust]: Timestamp: ' + sessionSuccessData.timestamp);
}
if (sessionSuccessData.adid != null) {
print('[Adjust]: Adid: ' + sessionSuccessData.adid);
}
if (sessionSuccessData.jsonResponse != null) {
print('[Adjust]: JSON response: ' + sessionSuccessData.jsonResponse);
}
};
// Set session failure tracking delegate.
config.sessionFailureCallback = (AdjustSessionFailure sessionFailureData) {
print('[Adjust]: Session tracking failure!');
if (sessionFailureData.message != null) {
print('[Adjust]: Message: ' + sessionFailureData.message);
}
if (sessionFailureData.timestamp != null) {
print('[Adjust]: Timestamp: ' + sessionFailureData.timestamp);
}
if (sessionFailureData.adid != null) {
print('[Adjust]: Adid: ' + sessionFailureData.adid);
}
if (sessionFailureData.willRetry != null) {
print('[Adjust]: Will retry: ' + sessionFailureData.willRetry.toString());
}
if (sessionFailureData.jsonResponse != null) {
print('[Adjust]: JSON response: ' + sessionFailureData.jsonResponse);
}
};
// Set event success tracking delegate.
config.eventSuccessCallback = (AdjustEventSuccess eventSuccessData) {
print('[Adjust]: Event tracking success!');
if (eventSuccessData.eventToken != null) {
print('[Adjust]: Event token: ' + eventSuccessData.eventToken);
}
if (eventSuccessData.message != null) {
print('[Adjust]: Message: ' + eventSuccessData.message);
}
if (eventSuccessData.timestamp != null) {
print('[Adjust]: Timestamp: ' + eventSuccessData.timestamp);
}
if (eventSuccessData.adid != null) {
print('[Adjust]: Adid: ' + eventSuccessData.adid);
}
if (eventSuccessData.callbackId != null) {
print('[Adjust]: Callback ID: ' + eventSuccessData.callbackId);
}
if (eventSuccessData.jsonResponse != null) {
print('[Adjust]: JSON response: ' + eventSuccessData.jsonResponse);
}
};
// Set event failure tracking delegate.
config.eventFailureCallback = (AdjustEventFailure eventFailureData) {
print('[Adjust]: Event tracking failure!');
if (eventFailureData.eventToken != null) {
print('[Adjust]: Event token: ' + eventFailureData.eventToken);
}
if (eventFailureData.message != null) {
print('[Adjust]: Message: ' + eventFailureData.message);
}
if (eventFailureData.timestamp != null) {
print('[Adjust]: Timestamp: ' + eventFailureData.timestamp);
}
if (eventFailureData.adid != null) {
print('[Adjust]: Adid: ' + eventFailureData.adid);
}
if (eventFailureData.callbackId != null) {
print('[Adjust]: Callback ID: ' + eventFailureData.callbackId);
}
if (eventFailureData.willRetry != null) {
print('[Adjust]: Will retry: ' + eventFailureData.willRetry.toString());
}
if (eventFailureData.jsonResponse != null) {
print('[Adjust]: JSON response: ' + eventFailureData.jsonResponse);
}
};
Adjust.start(adjustConfig);The callback function will be called after the SDK tries to send a package to the server. Within the callback function you have access to a response data object specifically for the callback. Here is a quick summary of the success session response data object fields:
messagemessage string from the server or the error logged by the SDK.timestamptimestamp string from the server.adida unique string device identifier provided by Adjust.jsonResponsethe JSON object with the reponse from the server.
Both event response data objects contain:
eventTokenthe event token string, if the package tracked was an event.callbackIdthe custom defined callback ID string set on event object.
And both event and session failed objects also contain:
willRetryboolean which indicates whether there will be an attempt to resend the package at a later time.
Like described in attribution callback section, this callback get triggered providing you info about new attribution when ever it changes. In case you want to access info about your user's current attribution whenever you need it, you can make a call to following method of the Adjust instance:
AdjustAttribution attribution = Adjust.getAttribution();Note: Information about current attribution is available after app installation has been tracked by the Adjust backend and attribution callback has been initially triggered. From that moment on, Adjust SDK has information about your user's attribution and you can access it with this method. So, it is not possible to access user's attribution value before the SDK has been initialized and attribution callback has been initially triggered.
The Adjust SDK offers you possibility to obtain some of the device identifiers.
To obtain the IDFA, call the getIdfa method of the Adjust instance:
Adjust.getIdfa().then((idfa) {
// Use idfa string value.
});Certain services (such as Google Analytics) require you to coordinate Device and Client IDs in order to prevent duplicate reporting.
To obtain the device Google Advertising identifier, it's necessary to pass a callback function to Adjust.getGoogleAdId that will receive the Google Advertising ID in it's argument, like this:
Adjust.getGoogleAdId().then((googleAdId) {
// Use googleAdId string value.
});To obtain the Amazon advertising identifier, call the getAmazonAdId method of the Adjust instance:
Adjust.getAmazonAdId().then((amazonAdId) {
// Use amazonAdId string value.
});For each device with your app installed on it, Adjust backend generates unique Adjust device identifier (adid). In order to obtain this identifier, you can make a call the getAdid method of the Adjust instance:
Adjust.getAdid().then((adid) {
// Use adid string value.
});Note: Information about adid is available after app installation has been tracked by the Adjust backend. From that moment on, Adjust SDK has information about your device adid and you can access it with this method. So, it is not possible to access adid value before the SDK has been initialised and installation of your app was tracked successfully.
If you want to use the Adjust SDK to recognize users whose devices came with your app pre-installed, follow these steps.
-
Create a new tracker in your dashboard.
-
Set the default tracker of your config object:
adjustConfig.defaultTracker = '{TrackerToken}';
Replace
{TrackerToken}with the tracker token you created in step 1. Please note that the Dashboard displays a tracker URL (includinghttp://app.adjust.com/). In your source code, you should specify only the six-character token and not the entire URL. -
Build and run your app. You should see a line like the following in your LogCat:
Default tracker: 'abc123'
You can put the Adjust SDK in offline mode to suspend transmission to our servers, while retaining tracked data to be sent later. While in offline mode, all information is saved in a file, so be careful not to trigger too many events while in offline mode.
You can activate offline mode by calling setOfflineMode with the parameter true.
Adjust.setOfflineMode(true);Conversely, you can deactivate offline mode by calling setOfflineMode with false. When the Adjust SDK is put back in online mode, all saved information is sent to our servers with the correct time information.
Unlike disabling tracking, this setting is not remembered between sessions. This means that the SDK is in online mode whenever it is started, even if the app was terminated in offline mode.
You can disable the Adjust SDK from tracking any activities of the current device by calling setEnabled with parameter false. This setting is remembered between sessions.
Adjust.setEnabled(false);You can check if the Adjust SDK is currently enabled by calling the function isEnabled. It is always possible to activatе the Adjust SDK by invoking setEnabled with the enabled parameter as true.
If your app makes heavy use of event tracking, you might want to delay some HTTP requests in order to send them in one batch every minute. You can enable event buffering with your config instance:
adjustConfig.eventBufferingEnabled = true;The default behaviour of the Adjust SDK is to pause sending HTTP requests while the app is in the background. You can change this in your config instance:
