The package needs to be provided to the **ReactInstanceManager** when it is built. To accomplish this you will need to insert an `.addPackage(new YourPackageName())` call to the `mReactInstanceManager = ReactInstanceManager.builder()` call chain. The package needs to be provided in the `getPackages` method of the `MainActivity.java` file. This file exists under the android folder in your react-native application directory. The path to this file is: `android/app/src/main/java/com/your-app-name/MainActivity.java`.
Refer to the code below and add the `addPackage` statement to your application's `MainActivity.java` file. This file exists under the android folder in your react-native application directory. The path to this file is: `android/app/src/main/java/com/your-app-name/MainActivity.java`.
```java ```java
mReactInstanceManager = ReactInstanceManager.builder() protected List<ReactPackage> getPackages() {
.setApplication(getApplication()) return Arrays.<ReactPackage>asList(
.setBundleAssetName("AnExampleApp.android.bundle") new MainReactPackage(),
.setJSMainModuleName("Examples/AnExampleApp/AnExampleApp.android") new AnExampleReactPackage()); // <-- Add this line with your package name.
.addPackage(new AnExampleReactPackage()) // <-- Add this line with your package name. }
.setUseDeveloperSupport(true)
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
``` ```
To make it simpler to access your new functionality from JavaScript, it is common to wrap the native module in a JavaScript module. This is not necessary but saves the consumers of your library the need to pull it off of `NativeModules` each time. This JavaScript file also becomes a good location for you to add any JavaScript side functionality.
