getActivity() returns null in Fragment function

Question

I have a fragment (F1) with a public method like this

public void asd() {
    if (getActivity() == null) {
        Log.d(\"yes\",\"it is null\");
    }
}

You can using onAttach or if you do not want to put onAttach everywhere then you can put a method that returns ApplicationContext on the main App class :

public class App {
    ...  
    private static Context context;

    @Override
    public void onCreate() {
        super.onCreate();
        context = this;
    }

    public static Context getContext() {
        return context;
    }
    ...
}

After that you can re-use it everywhere in all over your project, like this :

App.getContext().getString(id)

Please let me know if this does not work for you.
