I have developed a music player app in kotlin language. At present when I start another app's song, my app's song is also playing. both songs are playing simultaneously. I would like to add a functionality where the song should stop automatically when another app's media (audio/video) starts playing. How to add this functionality. What concept is behind it? Any hint or suggestion would be appreciated. thanks
You can take a look at this Documentation, https://developer.android.com/guide/topics/media-apps/audio-focus#audio-focus-change. where you will be given the option to add listener in the AudioFocusRequest Builder
to listen to Audio Focus Event and add your callback there.
alternatively ExoPlayer Library gives you the option to handle Audio Focus automatically on setAudioAttributes method on its Player implementation

I have an application which uses exoplayer to play videos.
When the user is on player page and presses the power button to close the screen I want the audio to keep playing in the background and notification should be visible to user with controls of play, pause , video metadata etc similar to what we have for every music playing app.
I can keep the audio of video playing from exoplayer using setPlayWhenReady(true).
But I am stuck in for notification. Should I be using MediaBrowserServiceCompat or I will have to create custom notification to handle it?
I think what you should do is to create ForegroundService and create notification as you mentioned to have the ForegroundService working. I think this post might help you:

Use a foreground service to implement something like this.This can help you
I want to stop my media player if external media player is playing.
I've implemented following code but it is called even when my app media player is playing.
if (audioManager.isMusicActive()) {
return;
}
How to distinguish between in-app media player and external media player?
Any help would be appreciated.
Two or more Android apps can play audio to the same output stream
simultaneously. The system mixes everything together. While this is
technically impressive, it can be very aggravating to a user. To avoid
every music app playing at the same time, Android introduces the idea
of audio focus. Only one app can hold audio focus at a time.
Further,
A well-behaved audio app should manage audio focus according to these
general guidelines:
Call requestAudioFocus() immediately before starting to play and
verify that the call returns AUDIOFOCUS_REQUEST_GRANTED. If you design
your app as we describe in this guide, the call to requestAudioFocus()
should be made in the onPlay() callback of your media session. When
another app gains audio focus, stop or pause playing, or duck the
volume down. When playback stops, abandon audio focus. Audio focus is
handled differently depending on the the version of Android that is
running:

I am making an app in which I've made a Service which plays Music from URLs. The thing is that my music Service is playing music correctly BUT when user plays any song with Native music player then BOTH(Native Player and My Music Service) are playing music simultaneously. I want to stop My Music Service when user started playing music with native player.
Is there any Broadcast Intent which i can register to Detect the
music player is started?
Is it possible to detect Music player Started?
Any Other Solution?
Any suggestions would appreciated.
I'll suggest a different approach, that I believe it's the correct approach.
the issue on your approach is that you're suggesting to check for one specific app. And there're tons of different music players, plus radio players, plus video players, plus games... and all of those should stop your music in case they want to play something.
So how you do it?
It's all explained in the Android Developers website.
You have to register an OnAudioFocusChangeListener, so, whenever a different app request to have the audio focus, your app can stop the music.
Step 1: Detect if the user has opened native music app. For this , you need to know the package name of your native music app.
Then refer to my answer here: Android how to know an app has been started and range apps priority according the starting times
Using that , the list taskinfo will have the list of all running activities, and as explained there, the first element of the list will be the activity in the foreground.
STEP 2: Once you detect native music app being activated using STEP 1 (by polling for it in the background) , then stop your app's service.
NOTE: You should do this in a background (using asynctask) or another service.
NOTE 2: The limitation of this method is that you can't actually stop the music player when the user clicks play in the native music app, since this method will help you detect only if the native music app is opened or not.
In my application I want to get start time of music player when user started and end time when it stops.I don't want to start any music player in my app. I just want to track user activity in device. So i want my application to get any notification when user started the music .
Do I get any intent for music player started and it stopped.Or do I get any intent for when user opens music files.
Is there any other method other than intent to capture the start time and and time when user starts music player.
Well you can implement the interface 'AudioManager.OnAudioFocusChangeListener' in which there is a method 'onAudioFocusChange' which lets you know if audio focus has been changed, and it can also tell if focus was gained or lost.
See this link, it explains the Audio Focus in detail. An application must gain audio focus through a request, and you can implement the 'AudioManager.OnAudioFocusChangeListener' and if there is focus gain, you can detect if the media player is running, (because some other application such as you tube may gain focus to play its audio), see this to see how to detect which application or service is currently running. You can find if audio has started to play, and if it was the media player or not.
Hope this helps. It was interesting question and I have learned some new things while searching for the answer!
I created a sample audio player application in android. In my application I used Play, Pause and Stop functions. Now I wish to add Loop functionality in my application. i.e., when I click the Loop button, recently played audio will play continuously, when I click Stop button the audio file will be stop. I go through the android developer site, I got a function setLooping(boolean). I set this my media player nothing will happen, how can I use this, in my code I used like this,
MediaPlayer mPlayer= new MediaPlayer();
mPlayer.setLooping(false);
you are setting the setLooping to false ,if you want to be repeted you must set it to true .You want it to be playing again and again right?
Use:
mPlayer.setLooping(true)
