Here is the start Class

public class StartActivity extends Activity {
private static final String FIREBASE_URL = "https://database.firebaseio.com/";
private Firebase myFirebaseRef = null;
View rootView;
String uid;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_start);

    Firebase.setAndroidContext(this);
    final ProgressBar p = (ProgressBar) findViewById(R.id.start_progress_bar);

}
private void checkUserLogin() {
                    myFirebaseRef.addAuthStateListener(new Firebase.AuthStateListener() {
                        @Override
                        public void onAuthStateChanged(AuthData authData) {
                            if (authData != null) {

                                System.out.println(myFirebaseRef.getKey());
                                Intent toMainActivity = new Intent(getApplicationContext(), MenuActivity.class);
                                uid = myFirebaseRef.getAuth().getUid();
                                toMainActivity.putExtra("user_id", uid);
                                finish();
                                startActivity(toMainActivity);

                            } else if (authData == null) {

                                Intent toMainActivity = new Intent(getApplicationContext(), LoginActivity.class);
                                startActivity(toMainActivity);
                                // user is not logged in
                            }

                    });
}
private Runnable task = new Runnable() {
    public void run() {

        checkUserLogin();
    }
};
@Override

    super.onStart();
    if(myFirebaseRef == null) {
        myFirebaseRef = new Firebase(FIREBASE_URL);
    }
    Handler handler = new Handler();
    handler.postDelayed(task, 3000);

}
@Override
protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(rootView);
    rootView = null;
    System.gc();

}
protected void unbindDrawables(View view) {
    if (view != null) {
        if (view.getBackground() != null) {
            view.getBackground().setCallback(null);
        }
        if (view instanceof ViewGroup && !(view instanceof AdapterView)) {
            for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
                unbindDrawables(((ViewGroup) view).getChildAt(i));
            }
            ((ViewGroup) view).removeAllViews();
        }

    }

}

}

How to&Answers:

I have also faced same problem with Firebase when run application below API 19(< 4.4.2) devices due to error of Multidex. Then below solution work for me:

In app module build.gradle

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

dependencies {
  // add dependency 
  compile 'com.android.support:multidex:1.0.1'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

update name in AndroidManifest.xml

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:name=".MyApplication"
    android:theme="@style/AppTheme">

     // ...
</application>

Crate a MyApplication.java file

public class MyApplication extends Application {

    @Override
    protected void attachBaseContext(Context base) {
       super.attachBaseContext(base);
       MultiDex.install(this);
    }

}

Answer:

In AndroidStudio try to do this:

  1. ctrl+alt+s
  2. Click on “Build, Execution, Deployment
  3. disable “Instant Run”

This should work

Answer:

Disabling instant run fixed the issue for me.

Android Studio -> Preferences -> Build, Execution, Deployment -> Instant Run

-Uncheck the box next to “Enable Instant Run…”

-Click OK

Answer:

I’m having the same issue, what i did is uninstall the app from device/emulator, and then, reinstall it again (from Android Studio, ‘run’ button).

Answer:

If you have recently changed the firebase dependency version in your gradle you may need to update to the latest version of Google Repository in the Android SDK manager as well.

If you cannot update the Google Repository at the time, try changing the gradle dependency version back to lower.

Answer:

Just insert below lines in your project AndroidManifest.xml file,
if they’re not in application tag

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
