Why getApplicationContext() in constructor of Activity throws null pointer exception?

Question

After some time spent bug hunting it turns out that :

public class MainActivity extends BaseActivity { // BaseActivity extends Activity

    public MainActi         


        

Answer 1

Wait for the end of onCreate to call this method.

public class MainActivity extends BaseActivity { 

    public onCreate(Bundle savedInstanceState) {
        super(savedInstanceState);
        getApplicationContext(); //activity has a context now
    }
}
