android.app.SuperNotCalledException : Activity did not call through to super. onCreate()
Here is my Android
media player code. When I run in debug mode with
the MediaPlayer mp = new MediaPlayer()
line breakpoint, I don’t know what’s missing from this code. All files in the zip
folder are 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 java.util.zip.ZipFile;
import org.apache.commons.io.IOUtils;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.Button;
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())
{
Log.i(MAIN_TAG,"Audio file found!");
MediaPlayer mp = new MediaPlayer();
FileInputStream fis = new FileInputStream(f);
mp.setDataSource(fis.getFD());
mp.prepare();
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)
{
Log.i(MAIN_TAG,e.toString());
}
}
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();
}
}
Solution
You did not call the onCreate()
method of the activity, which is the method of the
parent class (super class). Add a call to the onCreate()
method of MainActivity
:
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 ...
