react-native-billing | React Native bridge to InApp Billing on Android | Android library

With this, the linkcommand will do most of the heavy lifting for native linking. But, you will still need add your Google Play license key to the strings.xml (step 5). If you are using a React Native version less than v0.18 you will also have to do step 4.3 (override onActivityResult).
npm install --save react-native-billing or yarn add react-native-billing
react-native link react-native-billing
React Native version >= 0.29 Edit MainApplication.java. React Native version < 0.29 Edit MainActivity.java. Step 4.3 is only required if you are using a lower React Native version than 18.0 and/or your MainActivity class does not inherit from ReactActivity.
npm install --save react-native-billing
Add the following in android/setting.gradle
And the following in android/app/build.gradle
Update MainActivity or MainApplication depending on React Native version.
React Native version >= 0.29 Edit MainApplication.java. Add import com.idehub.Billing.InAppBillingBridgePackage; Register package: @Override protected List<ReactPackage> getPackages() { return Arrays.<ReactPackage>asList( new MainReactPackage(), // add package here new InAppBillingBridgePackage() ); }
React Native version < 0.29 Edit MainActivity.java. Step 4.3 is only required if you are using a lower React Native version than 18.0 and/or your MainActivity class does not inherit from ReactActivity. Add import com.idehub.Billing.InAppBillingBridgePackage; Register package in ReactInstanceManager: .addPackage(new InAppBillingBridgePackage()) Override onActivityResult: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { mReactInstanceManager.onActivityResult(requestCode, resultCode, data); } Larger example: // 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 .addPackage(new InAppBillingBridgePackage()) .setUseDeveloperSupport(BuildConfig.DEBUG) .setInitialLifecycleState(LifecycleState.RESUMED) .build(); ... } // Step 3: For RN < v0.18, override onActivityResult @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { mReactInstanceManager.onActivityResult(requestCode, resultCode, data); } ...
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:
