This article describes how to set up the Payment Links SDK for Android.

​
Requirements

Minimum target level24

​
Step 1 | Import the SDK

To import the Android Payment Links SDK, add the following implementation to your build.gradle file: 
implementation("com.appcharge:android-payment-links:1.3.0")
Then add the following to your settings.gradle file: 
repositories {
    mavenCentral()
}

​
Step 2 | Configure Permissions

In the Manifest file, add the necessary permissions to access the network state and enable incoming deeplink over HTTPS: 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<queries>
        <intent>
            <action android:name="android.intent.action.VIEW" />
            <data android:scheme="https" />
        </intent>
</queries>

​
Step 3 | Configure a URL Scheme

Next, add support for checkout activity and deeplink scheme: 
 <activity
    android:name="com.appcharge.core.CheckoutActivity"
		android:configChanges="orientation|screenSize"
    android:screenOrientation="unspecified"
    android:exported="true"
    android:launchMode="singleTask"
    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>
The intent-filter includes a scheme "acnative-{IDENTIFIER}". Change the {IDENTIFIER} to the last sequence of your package name. For example, if your package name is com.appcharge.mysupergame, the identifier will be mysupergame. This name must be lowercase with no spaces.
