android.app.SuperNotCalledException: Activity did not call through to super.onCreate()

Question

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 files in zip folder is played. But when I run the application in normal mode the first file is played and then I get this error:

android.app.SuperNotCalledException: Activity {com.example.mediaplayer/com.example.mediaplayer.MainActivity} did not call through to super.onCreate()

Code:

package com.example.mediaplayer;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.zip.ZipEntry;

import android.app.Activity;

public class MainActivity extends Activity {     
    private MediaPlayer mp;    
    private static final String MAIN_TAG ="ERROR";

@Override
protected void onCreate(Bundle savedInstanceState) {
     try {
    //final String file_loc= Environment.getExternalStorageDirectory().toString();
    //Log.i("location",file_loc);
         ZipFile zip = new ZipFile("/storage/emulated/0/AjeshDocument/sample.zip");

         for(int i=1;i<7;i++){

         ZipEntry entry = zip.getEntry("sample/rihanna_"+i+".mp3");                        
         if (entry != null) {
             InputStream in = zip.getInputStream(entry);
             // see Note #3.
             File tempFile = File.createTempFile("_AUDIO_", ".wav");
             FileOutputStream out = new FileOutputStream(tempFile);
             IOUtils.copy(in, out);

             // do something with tempFile (like play it)
             File f = tempFile;   
             try {
                 if (f.exists())

                     MediaPlayer mp = new MediaPlayer();

                     mp.setDataSource(fis.getFD());

                     //mp.setLooping(false);
                     mp.start();                         
                     //mp.stop();
                    // mp.release();
                     Log.i(MAIN_TAG,"Pronounciation finished!");
                 }  


               else
                 {
                     Log.i(MAIN_TAG,"File doesn't exist!!");
                 }

             }
             catch (IOException e)
             {

             }
         }
         else {
             // no such entry in the zip
         }
        } //for end
         mp.release();

     }  
         catch (Exception e) {
         // handle your exception cases...

         Log.i(MAIN_TAG,e.toString());

     }       

}

@Override
protected void onResume() {
    Log.w("Info", "App Resume");

    super.onResume();
}

@Override
protected void onStop() {
    Log.w("Info", "App stopped");

    super.onStop();
}

@Override
protected void onDestroy() {
     Log.w("Info", "App destoryed");

    super.onDestroy();
}

}

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 ...
