Android how to change the size and height of a video image in surface view for a media player

Want to resize video in surface view

I play videos in Media Player using Surface view and video holder ...

// but when implementing MediaPlayerControl on some devices they say that Micromax, iball, Akash tablet, it gives an abstract method error, inaccessible to track ACRA error tracking.

Now I want to have a solution to the mentioned problems:

• How to make the controls of the multimedia player active in all devices without fail due to the abstract method, as for the media controller in some devices.

• How to resize the image on the surface.

The code runs f9 on the galaxy samsung gt p1000 OS 2.2 and the cheaper WorldTeck device, etc.

But on Creative ziio 7 OS version 2.2.1 (480 * 800), the resolution density of 160 dpi video seems to be increased and disconnected from the edges.

The code is shown below:

/* Media Player Control is commented due to force close in some devices say *micromax,Creative ziio, akash etc */

    public class VideoViewerActivity extends Activity implements
            OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
            OnVideoSizeChangedListener, SurfaceHolder.Callback {
        // implements  ERROR in some devices , MediaPlayerControl
