how to detect when Music is played using Native Music Player? - android

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.

3rd party music apps launch when pressing play/pause on my app on FireTV

On the newest FireTV OS for the Fire Stick Lite 2020 I noticed that when we play a third party app like Spotify for example music keeps playing when we press the home button. This is normal behavior, however when I launch my app I request the audio focus using the AudioManager and OnAudioFocusChangeListener (because I'm also playing music and don't want it to be noisy) so the 3rd party music stops playing. However, when I press play on the FireTV to control my media(Using ExoPlayer) it pauses my app, takes me back to the Spotify app and I lose focus of my own application.
Youtube and Twitch handle this well, so I was wondering if there is anything I am missing or any documentation I should refer to.
Any help is appreciated.
Found the answer. Seems like I wasn't Media Session... According to
https://developer.android.com/guide/topics/media-apps/working-with-a-media-session
We would need to use Media Session to tell the System that there is a media session happening in your app and each time you tell the system that your player is active or playing then your application would have priority over the media controllers on the remote and no other application can access it unless you state that your media session is no longer active.

Hope this helps anyone else!

Switch between two activities and keep music playing

Here is what I want to achieve in my app: I have 3 menus in the startup page: PLAY , INSTRUCTIONS , HIGH SCORE.
I have theme music playing in the background with the help of MediaPlayer object. I just want that the theme music should be playing for the PLAY and INSTRUCTIONS menu, uninterrupted, i.e, if the activity changes from MAIN MENU to INSTRUCTIONS and vice-versa , the music should be playing uninterrupted. But the music should stop as soon as the PLAY activity is started. I don't know the best way to do it, but all I can think of is sending the MediaPlayer object that started the theme music to PLAY's oncreate and stop it there. is there any way to do this?
You want to use a Service to play the music (and to do so off of the main thread). Here are relevant pages on

Pause/Stop/Mute music at service interupts

I basically have an audio application that will be playing some music. I want to be able to pause/stop/mute the music when there is an interrupt.
These interrupts include: GPS directions, Phone Call, GPS, etc. (if there are more audio interupts, please let me know)
I already implemented the phone call interrupt, stops the music when phone call received and plays after phone call ends.
How would I do the other interrupts?
EDIT:
I noticed that Android's Play Music application does this. But I am unable to find the source code of that, not sure if that would be helpful.
Make sure you correctly ask for and release Audio Focus as described here:
http://developer.android.com/training/managing-audio/audio-focus.html
With multiple apps potentially playing audio it's important to think about how they should interact. To avoid every music app playing at the same time, Android uses audio focus to moderate audio playback—only apps that hold the audio focus should play audio.
Basically this allows the framework to handle interrupts properly as you cannot specifically code for every situation.

Android: Use running MediaPlayer

I' developing an Android app and in this app I've got a Android MediaPlayer and I want to ask, if I can access with this MediaPlayer to a running MediaPlayer, that was started by an other app?
For example I start a song with the Android Music app and the user opens my app. Is there a method to access and control this stream of the Android Music? So I can stop the music with stop() and start it start() and all the other functions?
If you are asking if there's a way to control a Media Player running in some other app from your app, then no. There is no way to do that.
If the other app is a service though, and that service allows control over its media player through intents, then you could control the other media player, but I'd be surprised if you got that lucky.

how to know when audio is started playing in android

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!
