in the project there's also a sample of how to use the helper.

you can find IranApps in-app billing documentation here

the library is uploaded to jCenter and you can see it below:

Easily reference the library in your Android projects using this dependency in your module's build.gradle file:

dependencies {
    compile 'ir.tgbs.iranapps:billing-helper:2.0'
}

1. download the library's jar file from jCenter at here
2. add the jar as a library to your project.
3. download IranApps in-app billing aidl file from here
4. put the downloaded aidl file in src/ir/tgbs/iranapps/billing
5. add IranApps billing permission to your manifest <uses-permission android:name="ir.tgbs.iranapps.permission.BILLING"/>
6. your ready to go, Enjoy

• in the activity that you want to do in-app billing requests create a new instance of InAppHelper inside onCreate.

@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
    super.onCreate(savedInstanceState, persistentState);
    setContentView(R.layout.activity_main);
    inAppHelper = new InAppHelper(this, new InAppHelper.InAppHelperListener() {
        @Override
        public void onConnectedToIABService() {
        }

        @Override
        public void onCantConnectToIABService(InAppError inAppError) {
        }

        @Override
        public void onConnectionLost() {
        }
    });
}

• Override onDestroy in that activity and call onActivityDestroy in InAppHelper

@Override
protected void onDestroy() {
    super.onDestroy();
    inAppHelper.onActivityDestroy();
}

• Override onActivityResult in that activity and call onActivityResult in InAppHelper

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    inAppHelper.onActivityResult(requestCode, resultCode, data);
}

if your activity is able to be destroyed and recreated you must save and restore the InAppHelper of that activity and update the listener of any operation that is currently in progress. for an example you can see the BaseInAppActivity and the implementation of 'InAppHolderFragment' that saves the data and can be retained in activity's onCreate method(also see the onCreate() method inside BaseInAppActivity on how the InAppHelper instance is created). and see BuyActivity on how the buy product operation's listener is updated inside onCreate() method.

if your using proguard in your app add this line to you proguard-rules.pro file

-keep class ir.tgbs.iranapps.billing.IranAppsIabService
