media player - Error streaming file on android 2.x, working on 4.x -

-

i wrote class extends android mediaplayer, class following

package it.ccevas.ccevasandroid;  import java.io.ioexception;  import android.media.audiomanager; import android.media.mediaplayer;  public class mymediaplayer extends mediaplayer {  public mymediaplayer(){     super();      setonpreparedlistener(new onpreparedlistener() {          public void onprepared(mediaplayer mp) {             start();         }     });      setonerrorlistener(new onerrorlistener() {           @override         public boolean onerror(mediaplayer mp, int what, int extra) {              if (what == -38){                  return true;              }              return false;         }     }); }  public boolean changesource (string urlfile){     try{         reset();         setaudiostreamtype(audiomanager.stream_music);         setdatasource(urlfile);         prepare();               seekto(0);      }  catch (illegalargumentexception e1) {         e1.printstacktrace();      } catch (securityexception e1) {         e1.printstacktrace();      } catch (illegalstateexception e1) {         e1.printstacktrace();      } catch (ioexception e1) {         e1.printstacktrace();     }     start();     return true;         }  }

it works fine on android 4.x

but on android 2.x works files stored on sd , not working remote files eg. "http://www.something.com/myfile.mp3"

permission on manifest right < uses-permission android:name="android.permission.internet" />

this log.cat

you try new url instead of "http://www.something.com/myfile.mp3" because url not prepare server.
