Build Status

the place burned down? lightning struck? slow business?

An Android library for handling In-App-Billing V3 (IABv3), based on Google's marketbilling sample code. The goal of this project is to build a reliable and tested library which can easily be included as an apklib in your (Maven based) projects.

Google's sample code has been refactored and made testable - at the moment there are over 100 unit tests covering most of the code base. It is currently used in the 1.5.x version of SMS Backup+.


Install the apklib to your local maven repository (it has not been published yet).

$ git clone
$ cd pay-me && mvn install

Add a maven dependency in your main project:


Instantiate and use the IabHelper in your activity:

@Override public void onCreate(Bundle bundle) {
    mIabHelper = new IabHelper(this, "Base64EncodedPublicKey");
    mIabHelper.startSetup(new OnIabSetupFinishedListener() {
        public void onIabSetupFinished(IabResult result) {
          if (result.isSuccess()) {
              // helper is ready to use
                  new OnIabPurchaseFinishedListener() {
                     public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
                        // handle purchase result
                  }, null

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    mIabHelper.handleActivityResult(requestCode, resultCode, data);
