Intent svc=new Intent(BeapSoundActivity.this, BackgroundService.class);
pendingIntent = PendingIntent.getService(BeapSoundActivity.this, 0, svc, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 2);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10*1000, pendingIntent);
I am using the above code to start my service in mt onCreate(),
I just want to stop this service when I click a Button to change my Activity
I used this line in my Button Click
stopService(new Intent(BeapSoundActivity.this, BackgroundService.class));
But it didnt worked for me

Thanks in advance
you created an alarm that start your service every 10 seconds. did you canceled it before stopping the service? (if not, use (AlarmManager)getSystemService(Context.ALARM_SERVICE).cancel)

The issue is it's playing good sometimes and sometimes it's stopping when we press back button or swiping other apps on home screen.I want to show the title track,image on UI.But with this code it's showing wrong images for some songs and for some it's even not showing the image even if the image exists.And after back screen pressed and so when we use other apps and get back to this It's showing simply TextView and normal android image.Is recreation of activity needed?Can we call Activity method from Service?How to solve the issues?Please help me.
You need background music service and communicate with Activity with message or bond activity to service, not call Activity method from service, that will cause cross process problem.
I actually opensource a Music Player with Background service, Lyric, from a business project I have wrote, you check this out:https://github.com/Wangchao0721/MusicPlayer
But I haven't got time to fill Readme for it, just check MediaPlayerActivity.java in activity package, you gonna know how to use this.
I have my VideoPlayerActivity.java and I want to open when I press on a video file from my sdcard through my file explore or another application

How can I used to stream files from another application program?
When I play video from main activity it plays and when I quit and go to file explorer and chose my player from custom dialog box and open I have that problem with uriString...
When navigating through your files you can set a clicklistener on a thumbnail. I use this code to fire up a full-screen video editor:
thumbNail.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (pathType.equals("image")) {
<snip>
}
else {
// music file
}
else {
// must be video
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(cmsURL + pathListFull,"video/mp4");
PackageManager packageManager = getActivity().getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
boolean isIntentSafe = activities.size() > 0;
if (isIntentSafe) {
startActivity(intent);
}
else {
Log.d("SHOWFILE", "no intents available");
}
}
}
});

I am new here. I was asked by my professor to play other audio while the same video is being played(for example a person doesn't understand English and wants the the app to play french ). I have used video view. One possible method was to mute the present audio and play the french audio stored in my sdcard. but video view supports no muting( i couldn't find one). I read that i have to go for media player instead of video view.
Please help...!! what should i do... Thanks in advance.
if you want to get access to the MediaPlayer of a VideoView you have to call MediaPlayer.OnPreparedListener and MediaPlayer.OnCompletionListener, then you can call setVolume(0f, 0f); function to set the volume to 0.
Do this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
VideoView videoView = (VideoView)this.findViewById(R.id.VVSimpleVideo);
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
videoView.setMediaController(mc);
String _path = "/mnt/sdcard/Movies/video5.mp4";
videoView.setVideoPath(_path);
videoView.setOnPreparedListener(PreparedListener);
videoView.requestFocus();
//Dont start your video here
//videoView.start();
}
MediaPlayer.OnPreparedListener PreparedListener = new MediaPlayer.OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer m) {
try {
if (m.isPlaying()) {
m.stop();
m.release();
m = new MediaPlayer();
}
m.setVolume(0f, 0f);
m.setLooping(false);
m.start();
} catch (Exception e) {
e.printStackTrace();
}
}
};
I am trying to use two instances of mediaplayer. When the first instance is played the second instance is prepared in another thread.and when first instance completes the file the second instance is started.
Problem: the second instance plays only audio, video is not visible.
Observation:If i prepare the second instance with the same surface holder as that of the first and start after first instance is completed it works fine.
