Enabling Multidex	Learn how to enable multidex on your Android application.

As more native dependencies are added to your project, it may bump you over the 64k method limit on the Android build system. Once this limit has been reached, you will start to see the following error whilst attempting to build your Android application:

Execution failed for task ':app:mergeDexDebug'.

To learn more about multidex, view the official Android documentation.

Enabling Multidex

Open the /android/app/build.gradle file. Under dependencies we need to add the module, and then enable it within the defaultConfig:

android {
    defaultConfig {
        // ...
        multiDexEnabled true
    }
    // ...
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

Once added, rebuild your application: npx react-native run-android.
