InApp Billing for Android

This is a simple bridge for InApp Billing (Purchase) on Android for React Native, accomplished by wrapping anjlab's inapp library.

Important: The JavaScript API and native module is very much subject to change in the near future, and should be viewed as just a simple implementation at the moment.

Installation with rnpm

1. npm install --save react-native-billing
2. rnpm link react-native-google-billing

With this, rnpm will do most of the heavy lifting for linking, but you will still need add your Google Play license key to the strings.xml (step 5).

Manual installation Android

1. npm install --save react-native-billing
2. Add the following in android/setting.gradle

...
include ':react-native-billing', ':app'
project(':react-native-billing').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-billing/android')

3. And the following in android/app/build.gradle

...
dependencies {
    ...
    compile project(':react-native-billing')
}

4. Register package in MainActivity.java

// Step 1; import package:
import com.idehub.Billing.InAppBillingBridgePackage;

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setBundleAssetName("index.android.bundle")
                .setJSMainModuleName("index.android")
                .addPackage(new MainReactPackage())
                // Step 2; register package, with your and send in the MainActivity as a parameter (this):
                .addPackage(new InAppBillingBridgePackage(this))
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.RESUMED)
                .build();

        ...
    }
    ...

5. Add your Google Play license key as a line to your android/app/src/main/res/values/strings.xml with the name RNB_GOOGLE_PLAY_LICENSE_KEY. For example:

<string name="RNB_GOOGLE_PLAY_LICENSE_KEY">YOUR_GOOGLE_PLAY_LICENSE_KEY_HERE</string>

Javascript API

All three methods returns Promises.

const InAppBilling = require("react-native-billing");

InAppBilling.getProductDetails(productId).then((details) => {
  console.log(details);
});

InAppBilling.purchase(productId).then((purchaseDetails) => {
  console.log(purchaseDetails);
});

InAppBilling.consumePurchase(productId).then((consumed) => {
  console.log("Is consumed: " + consumed);
});
