Supported version: In-app Billing Version 3 API

In the Code

  1. Add the corresponding billing permission

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

  2. If you want to delegate purchase verification to the library, set verifyMode to VERIFY_EVERYTHING and add your public key

    OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder();
builder.setVerifyMode(OpenIabHelper.Options.VERIFY_EVERYTHING);
builder.addStoreKey(OpenIabHelper.NAME_GOOGLE, googlePlayPublicKey);
mHelper = new OpenIabHelper(this, builder.build());

    Or
    if you don't want to keep public keys in the code, we strongly recommend you to verify purchases on a server side using Google Play Developer API. To do it, create OpenIabHelper with VERIFY_SKIP option and no public key.

    OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder();
builder.setVerifyMode(OpenIabHelper.Options.VERIFY_SKIP);
mHelper = new OpenIabHelper(context, builder.build());

    Then in the callback in case of success, just sent

    new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        if(result.isOK)
        if (storeName.equals(OpenIABHelper.NAME_GOOGLE)) {
            youMethodToVerifyPurchaseViaServer(purchase);
        }
    }
}

  3. Map the SKUs if they are different for the supported stores

    OpenIabHelper.mapSku(SKU_PREMIUM, OpenIabHelper.NAME_GOOGLE, "org.onepf.trivialdrive.gp.premium");
OpenIabHelper.mapSku(SKU_GAS, OpenIabHelper.NAME_GOOGLE, "org.onepf.trivialdrive.gp.gas");
OpenIabHelper.mapSku(SKU_INFINITE_GAS, OpenIabHelper.NAME_GOOGLE, "org.onepf.trivialdrive.gp.infinite_gas");

  4. In the proguard configuration file add

     -keep class com.android.vending.billing.**
