Can anyone help me. Please !!!
You need to stop and release the media player before your activity finishes. Try adding this to your activity:
#Override
protected void onDestroy() {
super.onDestroy();
if(mMediaPlayer != null)
{
mMediaPlayer.stop();
mMediaPlayer.release();
}
}

I think I have an error with "if else". How can I fix this ?
Try first mMediaPlayer.stop() and then release it by mMediaPlayer.release()
you can try this,
after release you should set mediaplayer null
private void releaseMediaPlayer() {
if (mMediaPlayer != null) {
mMediaPlayer.release();
mMediaPlayer = null;
}
}
I am developing an application that, among other things, plays some video files (streaming). I would like to prepare the MediaPlayer in one activity but play the video once it is ready in another activity, so that the user can navigate through the content of the first activity to kill some time. Is this possible?
There is an static MediaPlayer defined in the Application class, like this:
public class EGDF_App extends Application {
private static MediaPlayer mediaPlayer = null;
public static MediaPlayer getMediaPlayer() {
if(mediaPlayer == null)
return new MediaPlayer();
else
return mediaPlayer;
}
}
I have a button with a text (Load video). This text is changed when the video is ready, and when the user clicks on it, it triggers the following activity.
The problem is that I get the following error in LogCat:
09-06 20:43:34.606: D/ChapterPlayer(31999): surfaceCreated called
09-06 20:43:34.684: V/ChapterPlayer(31999): startVideoPlayback

String loadChapter = getString(R.string.load_chapter_button_text);

I would appreciate some help or advice. Thanks!
I don't think you're saving the MediaPlayer in your application, you're just returning a new instance of it. Try changing it as so:
public static MediaPlayer getMediaPlayer() {
if(mediaPlayer == null) {
mediaPlayer = new MediaPlayer();
}
return mediaPlayer;
}
I am a Android newbie. I want to design my personal videoplayer to play streaming music, so I use MediaPlayer and SurfaceView. The project plays streaming video successfully, but it can't be setloop. I have google many articles and read Android Developer. I can't figure out why mediaPlayer.setLooping(true) don't work here. Thanks^^
mediaPlayer.reset();
mediaPlayer.setDataSource(videoUrl);
mediaPlayer.setLooping(true);
mediaPlayer.prepare();
The code includes two parts: 1.Test_Videoplayer.java 2.Player.java
1.Test_Videoplayer.java
public class Test_Videoplayer extends Activity {
private SurfaceView surfaceView;
private Button btnPause, btnPlayUrl, btnStop;
private SeekBar skbProgress;
private Player player;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

btnPlayUrl = (Button) this.findViewById(R.id.btnPlayUrl);
btnPlayUrl.setOnClickListener(new ClickEvent());
