Firebase Storage crash on FirebaseApp initialization?

Question

I am working on Firebase Storage in Android. I am facing issue while initializing the FirebaseStorage reference.

MyCode :

MainActivity.java

public class MainActivity extends AppCompatActivity {

private StorageReference mStorage;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FirebaseStorage storage = FirebaseStorage.getInstance();  // App crash in this line
    mStorage = storage.getReferenceFromUrl("my firebase storage url");

} }

Application Class

public class FirebaseApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();

    Firebase.setAndroidContext(this);
    Firebase.getDefaultConfig().setPersistenceEnabled(true);
}

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

LogCat

The application is getting crashed in the MainActivity. Log says , Firebase is not initialized in the app but i have already initialize in the application class.

Please help me out , suggest me some solution.

Post the dependencies section of your build.gradle file. It looks like you are using both the legacy 2.5.x API (ex: `Firebase.setAndroidContext(this)`) and the new 9.x.x API (ex:`FirebaseStorage.getInstance()`). They cannot be used together.

Please make sure that you've added the dependency compile 'com.google.firebase:firebase-storage:11.0.4' in Gradle (app level)

If still, you face the same issue.

Error: com.google.firebase.storage.FirebaseStorage.getInstance(Unknown Source)

You may be using the Firebase Authentication. The issue will be resolved by making the version of firebase-auth and firebase-storage same.

compile 'com.google.firebase:firebase-storage:11.0.4'
compile 'com.google.firebase:firebase-auth:11.0.4'

Please also make sure you've import statement in Java file

import com.google.firebase.storage.FirebaseStorage;

It does look to me like you have not gone through the getting started steps for Android on Firebase:

https://firebase.google.com/docs/android/setup

You need to add a json config file to your application as a part of this process. Once you have set everything up, the Android SDK will initialize automatically for you.
