Thanks for your reply, but still not working.. Now i am trying with
this code...



import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.widget.MediaController.MediaPlayerControl;

public class Monster extends Activity implements
SurfaceHolder.Callback, MediaPlayer.OnPreparedListener {

SurfaceView mPreview;
SurfaceHolder holder;
MediaPlayer mediaplayer;
int mVideoWidth,mVideoHeight;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bushentry);
mPreview = (SurfaceView)findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
mediaplayer = MediaPlayer.create(this, R.raw.monster);
mediaplayer.start();
mediaplayer.setDisplay(holder);
mediaplayer.setOnPreparedListener(this);
}
public void surfaceChanged(SurfaceHolder holder, int format, int
width,
int height) {

}
public void surfaceCreated(SurfaceHolder holder1) {
mVideoWidth = mediaplayer.getVideoWidth();
mVideoHeight = mediaplayer.getVideoHeight();
if (mVideoWidth != 0  mVideoHeight != 0) {
holder.setFixedSize(mVideoWidth, mVideoHeight);
mediaplayer.start();
}
}
public void surfaceDestroyed(SurfaceHolder holder) {
}

public void onPrepared(MediaPlayer mp) {
mVideoWidth = mediaplayer.getVideoWidth();
mVideoHeight = mediaplayer.getVideoHeight();
if (mVideoWidth != 0  mVideoHeight != 0) {
holder.setFixedSize(mVideoWidth, mVideoHeight);
mediaplayer.start();
}
}
}


Still, the same problem, no error, but blank screen, any idea please..

2009-03-05 Thread Marco Nelissen

That won't work for a number of reasons:
- when you create the MediaPlayer and call start(), your display isn't
ready yet. You need to wait for the surfaceCreated() callback.
- you need to use the version of MediaPlayer.create() that takes a
SurfaceHolder parameter.

might want to search the archives)

 nothing is displaying, just blank screen only please guide me,

 import android.app.Activity;
 import android.media.MediaPlayer;
 import android.os.Bundle;

 public class MonsterEntry extends Activity {

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MediaPlayer mediaplayer = MediaPlayer.create(this,
 R.raw.monster);
mediaplayer.start();
}

You need to tell the mediaplayer where to display the video with
setDisplaySurface(). Check out the media demo apps on
developer.android.com.
