Import the Android SDK file into your project. Depending on the game engine, ensure it is loaded correctly.

​
Manifest Modification:

Make sure you have the following permissions inside the manifest file:

<uses-permission android:name="android.permission.INTERNET" />
<queries>
        <intent>
            <action android:name="android.intent.action.VIEW" />
            <data android:scheme="https" />
        </intent>
</queries>

Next, add support for the following activities:

<activity
    android:name="com.appcharge.core.CheckoutActivity"
		android:configChanges="orientation|screenSize"
    android:screenOrientation="unspecified"
    android:exported="true"
    tools:ignore="DiscouragedApi">
    <!-- Custom scheme -->
    <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="acnative-identifier"/>
        <data android:host="action"/>
        <data android:scheme="https"/>
    </intent-filter>
</activity>

Note that the intent-filter includes a scheme acnative-identifier. Change the identifier to your game name (lowercase, no spaces). This change will be relevant when setting up your configuration model in Step 2 of the integration.
