Answer 1

Just try this code:

  useLibrary 'org.apache.http.legacy'
  multiDexEnabled true


public class MyApp extends Application {


@Override
public void onCreate() {
    super.onCreate();
    MultiDex.install(this);

}

manifestfile:

    <application
    android:name="com.activity.MyApp"
    android:allowBackup="true"
    ....
   <activity name...../>
   />//application

It complains about duplicate package, com/google/android/gms/auth, you can try a gradle clean / clean project as a simple step. If this doesn't work it means that somewhere in the project dependencies you are including this package more than one time.

Answer 3

Just go to build tab and choose clean project. After clean project completed make rebuild project. then run your project.

i hope this will solve your problem.

Answer 4

please add this code in build.gradle(module:app)

    afterEvaluate {
    tasks.matching {
        it.name.startsWith('dex')
    }.each { dx ->
        if (dx.additionalParameters == null) {
            dx.additionalParameters = ['--multi-dex']
        } else {
            dx.additionalParameters += '--multi-dex'
        }
    }
}

Answer 5

You can try any of this.. it might works

1. Clean and rebuild the module or,
2. Invalidate / restart android studio or,
3. Check Gradle dependencies duplicate and clean the gradle at the right taskbar or,
4. add multiDexEnabled true in your gradle defaulConfig

Answer 6

A duplicate in the build.gradle file was the issue. Firebaseui was causing the build error.
