Where to put Firebase.setAndroidContext() function

Question

I\'m trying to play a bit with Firebase and Android.
I have one RegisterActivity, and one MainActivity. My current flow is - start with M

You can do both. If you set it just once then it should be here. Anywhere else and your app will crash. Debugger will say that you have not setAndroidContext():

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Firebase.setAndroidContext(this);
// The rest of your code goes here

If you want to use for multiple activities then create a class that has the same name as the app, make sure that the class extends Application.

public class NameOfApp extends Application {

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

    Firebase.setAndroidContext(this);
}

}

After that update the application tag in the manifest.xml file with the following:

android:name=".NameOfApp"
