Android.app.supernotcalledexception: Activity Did Not Call Through To Super.oncreate()

Here is my Android Media player code. I don't know what I am missing in this code, when I run with breakpoint at line MediaPlayer mp = new MediaPlayer() in Debug mode. All the file

Solution 1:

You didn't call the Activity's onCreate() method, i.e the super class' one. Add the call to MainActivity's onCreate() method:

public class MainActivity extends Activity {

    private MediaPlayer mp;    
    private static final String MAIN_TAG ="ERROR";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState); // this line is missing

    // your code below ...
