App crashes on receving notification

I am using this package with expokit (detached). On sending the notifictaion the app crashes. I searched around to find that adding

compile 'com.google.firebase:firebase-messaging:11.8.0'

worked for some. But in my case it produces

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

Here’s the app/build.gradle file

apply plugin: 'com.android.application'

@anish000kumar I used this trick. I’m not good at Java so I can’t be sure this code is good. But my problem was solved.

public class MainApplication extends MultiDexApplication implements ReactApplication {
  public List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
      new FIRMessagingPackage()
    );
  }

  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new FIRMessagingPackage()
      );
    }
  };

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }
}

implements ReactApplication should solve the issue
