Best practice to pass Context to non-activity classes?

Question

So, my first major application is almost coded and I\'m doing optimizations on my code. The app works fine, but I\'m not sure about my way of passing the context to other cl

Answer 1

You could also create a static instance reference to your MainActivity initialized in the onCreate() method

public class MainActivity extends AppCompatActivity {

    public static MainActivity mMainActivity;

    @Override
    private onCreate(Bundle savedInstanceState){

    //...

    mMainActivity = this;

    }
}

and call the context like this:

MainActivity.mMainActivity;

or write a method getInstanceOf() if it's clearer and/or you prefer using an accessor

MainActivity.getInstanceOf();

This strategy might provide you with some flexibility if you decide later that you would like to call an instance method contained in your main activity like so:

MainActivity.mMainActivity.myInstanceMethod();

Just a suggestion. Criticism is welcome and encouraged.
