How to access programmatically wide angle camera in android studio?

Im quite new to Android and I'm looking to find a way how to access the wide angle camera. I know how to list all my cameras on a certain device and I know how to see which camera I'm opening. I need to know how to set my camera to open the wide angle one. Thanks in advance ! I also read everything in android developers but there is nothing mentioning about the wide angle camera. And this is how I'm opening/activating my camera.

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

here is it

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
Caused by java.lang.SecurityException
Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION

You should use a foreground service inside the fragment to capture the screen.
Find below links for how to use the foreground service 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.

Taking a picture in my app and saving it in the gallery

I have tried adding the following but, if it's correct, I can't seem to put it in the correct place:
MediaScannerConnection.scanFile(this, new String[]{file.toString()}, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("External Storage", "Scanned" + path + ":");
Log.i("External Storage", "-> uri=" + uri);
}
});
Thanks for any help. Much appreciated.

This means "context". You need to place the code within the activity class, once the image has been fetched from the camera. Also call connect before calling scanFile. You can try below code.
MediaScannerConnection.scanFile(CameraPhotoActivity.this, new String[]{file.toString()}, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("External Storage", "Scanned" + path + ":");
Log.i("External Storage", "-> uri=" + uri);
}
});
