I have done following to check a permission inside a fragment.

if (ActivityCompat.checkSelfPermission(getContext(),            android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&            ActivityCompat.checkSelfPermission(getContext(),                    android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {         requestPermissions(getActivity(),                new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION,                        android.Manifest.permission.ACCESS_FINE_LOCATION},                REQUEST_LOCATION);    } else {        Log.e("DB", "PERMISSION GRANTED");    }

Update

Since Fragment.requestPermissions is now deprecated, Google advises using registerForActivityResult instead.

I have done the request like this:

val permissionLauncher = registerForActivityResult(    ActivityResultContracts.RequestPermission()) { isGranted ->    if (isGranted) {        // Do if the permission is granted    }    else {        // Do otherwise    }}permissionLauncher.launch(Manifest.permission.ACCESS_FINE_LOCATION)
