Hi,

I was working on developing a VideoPlayer. I am getting an error while
running the .mp4 file  on VideoView. This error occurs when I click on the
video view when the video is playing or if I start the video directly. The
error dialogue that appears on the screen says application stopped
unexpectedly.

Does anyone knows whats wrong with my code. Is there any other thing that I
need to do like adding permissions or intent filters.

Here is the code that can give more understanding about my application Video
Player..

public class VideoPlayer extends Activity {
    VideoView videoview;
    Context context;
    Bundle bundle;
    Intent sender;
    volatile boolean FLAG_FOR_FAVORITE;
    volatile boolean FLAG_FOR_PLAY_PAUSE = false;
    MediaController mediaController;
    TextView wordtext;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        context = this.getApplicationContext();
        sender = this.getIntent();

        setContentView(R.layout.videoplayer);

        Bundle retrieving_bundle = sender.getExtras();
        String wordname = retrieving_bundle.getString("txtstring");
        String filename = "/sdcard/" + wordname + ".mp4";
        ImageButton playpause = (ImageButton)findViewById(R.id.playpause);

        mediaController = new MediaController(context);
        wordtext = (TextView)findViewById(R.id.vocabularyword);
        wordtext.setText(wordname);

        ///////////////Code for setting video View //////////
        try{
        videoview = (VideoView)findViewById(R.id.wordvideo);
        videoview.setVideoPath(filename);
        videoview.setMediaController(mediaController);
        videoview.requestFocus();
        //videoview.start();                         *This gives an error if
not commented This is what I meant by running directly*
        videoview.setClickable(false);
        videoview.setOnClickListener(new OnClickListener(){
            public void onClick(View v){
                if(FLAG_FOR_PLAY_PAUSE == false){
                    FLAG_FOR_PLAY_PAUSE = true;
                    videoview.start();
                }
                ////to remove from favorites ///////////
                else if(FLAG_FOR_PLAY_PAUSE == true){
                    FLAG_FOR_PLAY_PAUSE = false;
                    videoview.pause();
                }

            }
        });
        }
        catch(Exception e){
            Log.v("video",e.getMessage());
        }

        playpause.setOnClickListener(new OnClickListener(){
            public void onClick(View v)
            {
                ImageButton pauseplay =
(ImageButton)findViewById(R.id.playpause);
                ///// to add to favorites/////////////
                    if(FLAG_FOR_PLAY_PAUSE == false){
                        pauseplay.setImageResource(R.drawable.pause);
                        FLAG_FOR_PLAY_PAUSE = true;
                        videoview.start();
                    }
                    ////to remove from favorites ///////////
                    else if(FLAG_FOR_PLAY_PAUSE == true){
                        pauseplay.setImageResource(R.drawable.play);
                        FLAG_FOR_PLAY_PAUSE = false;
                        videoview.pause();
                    }
               }
        });

      }


The logcat shows the following:
