By using MediaPlayer code:
=============================
private void playVideo() {
try {
String path = mPath.getText().toString();
Log.v(TAG, "path: " + path);
if (path.equals(current) && mp != null) {
mp.start();
return;
}
path="/sdcard/watch/movie.mp4";
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
mp = new MediaPlayer ();
mp.setOnErrorListener(this);
mp.setOnBufferingUpdateListener(this);
mp.setOnCompletionListener(this);
mp.setOnPreparedListener(this);
// mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setScreenOnWhilePlaying(true);
mp.setDisplay(mPreview.getHolder());
mp.setDataSource(path);
mp.prepare();
Log.v(TAG, "Duration: ===>" + mp.getDuration());
mp.start();
} catch (Exception e) {
Log.e(TAG, "error: "+ e.getMessage(), e);
if (mp != null) {
mp.stop();
mp.release();
}
}
}
