I am trying to build react-native in release mode.

CodePudding user response：

To fix this issue, you can try using the --minimize-warning flag when building the release version of the app, or try using a tool like react-native-clean-project to remove duplicated dependencies. Additionally, you can try to check your dependencies and see if there is any duplicate libraries or classes that you can remove.

CodePudding user response：

Add multidex in /android/app/build.gradle file

android {
defaultConfig {
    // ...
    multiDexEnabled true // <-- ADD THIS in the defaultConfig section
}
// ...
}

dependencies {
  implementation 'androidx.multidex:multidex:2.0.1'  // <-- ADD THIS DEPENDENCY
}

Then in android/app/src/main/java/.../MainApplication.java

// ... all your other imports here
import androidx.multidex.MultiDexApplication; // <-- ADD THIS IMPORT


// Your class definition needs `extends MultiDexApplication` like below
public class MainApplication extends MultiDexApplication implements ReactApplication {

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