###Dependency Amazon billing provider depends on proprietary in-app-purchasing.jar which can be found within Amazon Mobile App SDK.

You can download it yourself and manually add it to your project, or user our GitHub hosted repo instead:

allprojects {
  repositories {
    ...
    // third-party dependencies
    maven { url 'https://raw.githubusercontent.com/onepf/OPF-mvn-repo/master/' }
  }
}

Dependencies:

dependencies {
    compile 'org.onepf:opfiab-amazon:0.2.2@aar'
    compile 'com.amazon:in-app-purchasing:2.0.61'
}

Adding as jar

Add following entries to your AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <receiver
        android:name="com.amazon.device.iap.ResponseReceiver"
        android:exported="true">

            <action
                android:name="com.amazon.inapp.purchasing.NOTIFY"

Usage

final AmazonBillingProvider amazon = new AmazonBillingProvider.Builder(context)
                // optional
                .setPurchaseVerifier(new MyAmazonPurchaseVerifier())
                // optional
                .setSkuResolver(new MyAmazonSkuResolver())
                .build();

Purchase Verification

According to official documentation Amazon recommends using server-side purchase verification.
Unfortunately that means you'll have to make your own implementation of PurchaseVerifier interface.
