How to check permission in fragment

Question

I want to check a permission inside a fragment.

my code:

        // Here, thisActivity is the current activity
        if (ContextCompat.checkSelfPe         


        

Answer 1

Fragment has requestPermissions() and onRequestPermissionsResult() methods, use it.

But checkSelfPermission() is from ActivityCompat (not require Activity, only Context).

if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
    requestPermissions( //Method of Fragment
        new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 
        REQUEST_PERMISSIONS_CODE_WRITE_STORAGE
    );
} else {
    downloadImage();
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == REQUEST_PERMISSIONS_CODE_WRITE_STORAGE) {
        if (permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            proceedWithSdCard();
        }
    }
}

Answer 2

onRequestPermissionsResult is invoked in the activity not the fragment. Try overriding onRequestPermissionsResult in the activity instead.

Answer 3

To handle permissions in a Fragment call requestPermissions method. If you override onRequestPermissionsResult method in both fragment and activity, containing that fragment, make sure to call super.onRequestPermissionsResult(...) in the activity method to propagate call to the onRequestPermissionsResult method in the fragment.
