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:
