Request runtime permissions from v4.Fragment and have callback go to Fragment?

Question

I\'m having a weird issue that is causing a conflict. I had to switch to native Fragments to fix it, but there are bugs with that.

My original problem:

Answer 1

You can use this part of code

requestPermissions(new String[]{Manifest.permission.GET_ACCOUNTS}, PERMISSION_REQUEST_CODE);

Answer 2

I faced the same situation recently, when I needed to check for a permission inside the support fragment and get a callback there.

I was able to use ContextCompat to checkSelfPermission and then as @NasaGeek said called android.support.v4.app.Fragment's requestPermissions to request the permission and then got a call back to onRequestPermissionsResult in v4 Fragment.

Hope this helps.

Thanks.

Answer 3

In my case I have requested the permission from the fragment and also need to get the response in fragment.

But my phone running on android 8.1

so I was need to add one more condition for check this

so eventually there is my solution

private void doOnWazeButtonClick()
{
    int permissionStatus = PackageManager.PERMISSION_DENIED;

    if (getContext() != null)
    {
        permissionStatus = ContextCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION);
    }

    if (permissionStatus == PackageManager.PERMISSION_GRANTED)
    {
        showContentWaze();
    }
    else
    {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
        {
            Objects.requireNonNull(getActivity()).requestPermissions(new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_PERMISSION_ACCESS_FINE_LOCATION);
        }
        else
        {
            requestPermissions(new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_PERMISSION_ACCESS_FINE_LOCATION);
        }
    }
}

Answer 4

Adding this to the parent activity works for me:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    List<Fragment> fragments = getSupportFragmentManager().getFragments();
    if (fragments != null) {
        for (Fragment fragment : fragments) {
            fragment.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
}

Answer 5

I don't know if it's recently fixed by google, but I can reach the expected result without doing any tricks.

The most important thing is to call super.onRequestPermissionsResult(requestCode, permissions, grantResults); in the activity, so it will pass the result to fragment if it's requested from fragment.

So, what I do is:

1) in fragment, ask permission using v4 fragment.requestPermissions(permissions, requestCode)

2) in activity's onRequestPermissionsResult, must call super.onRequestPermissionsResult(requestCode, permissions, grantResults);

3) in fragment's onRequestPermissionsResult, write the code I want to handle the result.

Answer 6

v4.Fragment works well. I have an issue with nested fragment of v4.Fragment. Permission is asked, but the callback onRequestPermissionsResult() is never called in nested fragment!
