onDeeplink() called too early on Android

[Daniel-Dobson]

Hi, thanks for the knowledge and code you have shared 👍

I have encountered an issue where if I use a deep link to start my app on Android, the intent parameters that I pass will not 'make it through' to the app, when it is started 'from cold'. If however they app is already running, and I click the same deep link, then all 3 of the parameters in my href link reach the app.

I think this may be a timing issue with onDeeplink() being called before the Unity App has fully loaded? I think my parameters and scheme must be correct as they do indeed reach the app and get displayed if it is already running. They are in the following format:

MyApp

Thanks in advance,

This may relate to the

com.unity3d.player.UnityPlayer.UnitySendMessage(gameObject, deeplinkMethod, deeplink);

method, I am investigating this possibility.

Update - As a workaround to this problem I am using the following, called from Start():

#if UNITY_ANDROID
    private void RetreiveDeeplinkOnAndroid()
    {
#if !UNITY_EDITOR
        AndroidJavaClass unityPlayer         = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject currentActivity    = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
        AndroidJavaObject intent             = currentActivity.Call<AndroidJavaObject>("getIntent");
        string dataString                    = intent.Call<string>("getDataString");
        if (dataString.Length > 0)
        {
            decodedDeeplink = WebUtils.DecodeUrlString(dataString);			
        }
#endif
    }
#endif

It fixes the issue for me, but I still use onDeepLink() on Android for when the App is already running, to avoid having to continuously poll getDataString() while the app is running in case it has changed.

@Daniel-Dobson
App crash if you start the app without a deep link Unity 2017.3.03f -> solution add a try catch

[Daniel-Dobson]

Ah interesting have not tried it with this version of Unity yet - where did you place the try/catch?
