Answer 1

You may create MyApplication class, inherited from the Application, then inside that class do the following:

public class MyApplication extends Application {
    private static MyApplication instance;

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

    public static Context getContext() {
        return instance;
    }

After that, you may use MyApplication.getContext() anywhere if you need a context and don't have an Activity lying around.
