How to have a single instance of exoPlayer in a background?

I have almost a week figuring out how should I have one instance of exoplayer in background.
I want to use this instance in a playerview and in notification as well. Problem I am facing now, the player plays well, after a time it pauses (to release resource I guess), but when i click play it plays again, when i click other oudio, I get two audio playing at same time.
Here are my codes.

I also had to create other service to remove notification when the
user kill app by clearing app from recent apps.
here is it
MyAppService extends Service {
#Override
public void onTaskRemoved(Intent rootIntent) {
super.onTaskRemoved(rootIntent);
Intent i = new Intent(MyAppService.this,BackgroundPlayingService.class);

I don't take this as a best approach, but it gave me a quick solution while waiting for a better approach.
I will pot the app link here when it's available in playstore.

Screen recording app does not work on Android 10

I have an application for recording a screen, it does not work on android version 10. As I understand it, this is due to privacy changes in force in Android 10. Now for any application using MediaProjection api, must specify an attribute android:foregroundServiceType= in the service tag under the manifest, but my application uses MediaProjection in the fragment, not the service. Is it possible to make MediaProjection work from a fragment, or do I need to redo it?
Sorry for my bad english
Here is a mistake

Android: Camera2 API crashes when trying to record a second time

I've been trying for hours now, still can't seem to get this to work..
Using this as reference. I coded an application that records and saves a video. I have no problems running the reference application but many issues occurred when i ran my own application.
Issue:
The application have no issues recording video, saving the video, etc. However after recording and saving the first video, if i try to record a second video it crashes. The second error is supposedly caused by MediaRecorder: prepare failed: -2147483648, which in turned caused a IllegalStateException.(Log below) How do I go about solving this issue?

E/recordOnClick: Calling mediaRecorder.start()

I've solved the issue, with reference from this site
by removing the line mediaRecorder.setVideoFrameRate(60);
The application now runs without any issues.
