Thanks for the Previous satisfactory answers.Now i m working in
Android division & challenge is now to play vedio file from sdcard.it
sounds easy.But Obstacle is File is >300 MB (like 1 GB). Android
sdcard accessing doesn't support >300 MB. So I decided to derive the
Vedio in Smaller Chunks. My code is as below.But Error is, Vedio can't
be played.please have a look & also see the DDMS CatLog at last.
**CODE:**
public class VideoViewDemo extends Activity {
private static final String TAG = "VideoViewDemo";
private VideoView mVideoView;
private EditText mPath;
private ImageButton mPlay;

super.onCreate(icicle);

mPath.setText("sdcard/E0010023.mp4");
mPlay = (ImageButton) findViewById(R.id.play);
mPause = (ImageButton) findViewById(R.id.pause);
mReset = (ImageButton) findViewById(R.id.reset);
mStop = (ImageButton) findViewById(R.id.stop);
mPlay.setOnClickListener(new OnClickListener() {
