Error on stream media on android

i have this code for play radio stream on internet, this code like :-

package com.example.kam;

import java.io.IOException;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

import android.media.AudioManager;
import android.media.MediaPlayer;


public class MainActivity extends Activity {
    public MediaPlayer mp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
    protected void onResume (){
        super.onResume();

        mp = new MediaPlayer();
        try {
            mp.setDataSource("http://radio.arabhosters.com:8015/");
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            mp.prepare();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } //also consider mp.prepareAsync().
        mp.start();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);

        return true;
    }

}

when i run this code i see this exception :-

My guess would be that you're never calling release() on your MediaPlayer. A simple way (at least if I'm reading the logcat correctly) to solve your problem would be to place a reset() call before your instantiation. Like this:

mp.reset();
mp.setDataSource("http://radio.arabhosters.com:8015/");

One thing though: you should read the whole MediaPlayer state diagram to really understand what you should be doing.
