How to get package name from anywhere?

I am aware of the availability of Context.getApplicationContext() and View.getContext(), through which I can actually call Context.getPackageName() to retrieve the package name of an application.

They work if I call from a method to which a View or an Activity object is available, but if I want to find the package name from a totally independent class with no View or Activity, is there a way to do that (directly or indirectly)?

Solution

  • An idea is to have a static variable in your main activity, instantiated to be the package name. Then just reference that variable.

    You will have to initialize it in the main activity's onCreate() method:

    Global to the class:

    public static String PACKAGE_NAME;

    Then..

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

    PACKAGE_NAME = getApplicationContext().getPackageName();
}

    You can then access it via Main.PACKAGE_NAME.
