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

You should use a foreground service inside the fragment to capture the screen.

As mentioned in the comment, you can get the absolute path from the saved image and pass it through an intent to the Activity that it needs it.
To achieve this, you might want to convert your image file to a BitMap first, which will give you the actual path of the image (sometimes .getAbsolutePath() method returns a wrong file path, so it is a better solution to convert your image to a bitmap first).
This can be achieved:
String filePath = file.getPath();
Bitmap imgBitmap = BitmapFactory.decodeFile(filePath);
Then to obtain the real path of the image you saved you need to
1) Obtain the Uri of the created Bitmap:
public Uri getUri(Context context, Bitmap imgBitmap) {
ByteArrayOutputStream bOutputStream = new ByteArrayOutputStream();
String path = MediaStore.Images.Media.insertImage(context.getContentResolver(),
imgBitmap, "Title", null);
return Uri.parse(path);
}
2) Fetch the real path from Uri:
public String getRealPath(Uri uri) {
String [] proj={MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
In your first activity you can pass the path of your image through an intent to the other activity, then fetch it and display it/etc.
Intent intent = new Intent(context,OtherActivity.class);
intent.putExtra("PATH",path);
startActivity(intent);
Receive the data you passed:
Intent intent = getIntent();
String path = intent.getStringExtra("PATH");
//convert the path to image/bitmap and display the image
You can also pass the entire Bitmap to the Activity you need it, but I strongly recommend that you don't, because it will use a lot of memory.

BLE image transfer

Here is the code to convert an image to byte array and and send to ble device
i am not able to send complete data and its stopping nearly at 1kb
what are the methods to send large data to ble .
will it be appropriate to use delay in the data transfer and if so can you share the code
if anyone has any code to send data upto 1mb please do share

IllegalStatException is thrown when start mediaRecorder onActivityResult()

i have problem to build screen recording function when we are on video calling. i mean i want to start record screen and video calling at the same time. try to combine source code between this https://www.simplifiedcoding.net/video-call-android-tutorial/ and this http://www.truiton.com/2015/05/capture-record-android-screen-using-mediaprojection-apis/ but app suddenly crash when start record screen while on video call.
the code shown below
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode != REQUEST_CODE) {
Log.e(TAG, "Unknown request code: " + requestCode);
return;
}
if (resultCode != RESULT_OK) {
Toast.makeText(this,
"Screen Cast Permission Denied", Toast.LENGTH_SHORT).show();
mToggleButton.setChecked(false);
return;
}
mMediaProjectionCallback = new MediaProjectionCallback();
mMediaProjection = mProjectionManager.getMediaProjection(resultCode, data);
mMediaProjection.registerCallback(mMediaProjectionCallback, null);
mVirtualDisplay = createVirtualDisplay();
mMediaRecorder.start();
}
and this is the logcat

I was facing the same issue.
java.lang.IllegalStateException is due to that you are accessing the main thread view from another thread, // Play dial tones mDialTone.start();, which is giving the exception. Just call initRecorder() on main thread. It will resolve your problem.
