Android In-App Billing v3 Library

This is a simple, straight-forward implementation of the Android v3 In-app billing API.

It supports only 'Managed Product' purchases (for now).

Getting Started

• You project should build against Android 2.2 SDK at least.

• Add this Android In-App Billing v3 Library to your project.

• Open the AndroidManifest.xml of your application and add this permission:

  <uses-permission android:name="com.android.vending.BILLING" />

• Create instance of BillingProcessor class in your Activity source code:

  BillingProcessor bp;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		bp = new BillingProcessor(this);
	}

• Implement IBillingHandler Interface to handle purchase results and errors:

	bp.setBillingHandler(this);

• override Activity's onActivityResult method:

  @Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (!bp.handleActivityResult(requestCode, resultCode, data))
			super.onActivityResult(requestCode, resultCode, data);
	}

• Call purchase(productId) method for a BillingProcessor instance:

bp.purchase("YOUR PRODUCT ID FROM GOOGLE PLAY CONSOLE HERE");

• That's it! A super small and fast in-app library ever!

• And dont forget to release your BillingProcessor instance!

	@Override
	public void onDestroy() {
		if (bp != null) 
			bp.release();
		
		super.onDestroy();
	}

IBillingHandler callback interface

has 4 methods:

  void onProductPurchased(String productId);

called then requested PRODUCT ID was successfully purchased

	void onPurchaseHistoryRestored();

called then purchase history was restored and the list of all owned PRODUCT IDs was loaded from Google Play

	void onBillingError(int errorCode, Throwable error);

called then some error occured. See Constants class for more details

	void onBillingInitialized();

called then BillingProcessor was initialized and its ready to purchase
