khalti-android

SDK for Khalti Android App

Installation

Add the following line to dependency section in build.gradle file

compile 'com.khalti:khalti-android:1.1.0'

It is recommended that you update your support libraries to the latest version. However, if you're unable to update the libraries add the following line instead.

compile ('com.khalti:khalti-android:1.1.0') {
        transitive = true
    }

Note : We recommend you to use the latest version of Build tools and Support libraries for maximum compatibility.

In order to build and run this project, please use Android Studio 3 and please note that the minimum Build tools and Support libraries version should be 26.

compileSdkVersion 26
buildToolsVersion '26.0.2'

compile 'com.android.support:appcompat-v7:26.1.0'

In order to add support library 26, add the Google's maven url in build.gradle

repositories {
        jcenter()
        mavenCentral()
        maven { url "https://maven.google.com" }
    }

Usage

Layout

You can add it to your xml layout

<khalti.widget.KhaltiButton
            android:id="@+id/khalti_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

Or, use it in Java

KhaltiButton khaltiButton = new KhaltiButton();

Configure

Configure Khalti Checkout by passing an instance of Config class

When instantiating Config class pass public key, product id, product name, product web url, amount (in paisa) and a new instance of OnCheckOutListener.

Config config = new Config("Public Key", "Product ID", "Product Name", "Product Url", amount, new OnCheckOutListener() {

            @Override
            public void onSuccess(HashMap<String, Object> data) {
                Log.i("Payment confirmed", data+"");
            }

            @Override
            public void onError(String action, String message) {
                Log.i(action, message);
            }
        });

Additionally, Config class also accepts a HashMap parameter which you can use to pass any additional data. Make sure you add a merchant_ prefix in your map key.

HashMap<String, Object> map = new HashMap<>();
        map.put("merchant_extra", "This is extra data");
        
        Config config = new Config("Public Key", "Product ID", "Product Name", "Product Url", amount, map, new OnCheckOutListener() {

            @Override
            public void onSuccess(HashMap<String, Object> data) {
                Log.i("Payment confirmed", data);
            }

            @Override
            public void onError(String action, String message) {
                Log.i(action, message);
            }
        });

Finally set your config in your KhaltiButton.

khaltiButton.setCheckOutConfig(config);
