Android permission dialog not displaying

Question

I have found a few other questions about this issue but none of the answers have solved it for me. I'm trying to request the fine location permission, but there is no dialog shown. Here's what I'm doing:

int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);

if(permissionCheck == PackageManager.PERMISSION_GRANTED) {
    Log.d("Location","Location permission already granted"); // Not logged
    // Do other stuff
}
else {
    Log.d("Location", "Requesting location permission"); // This is logged

    ActivityCompat.requestPermissions(this, 
        new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_ENABLE_LOCATION);
 }

No dialog appears, and onRequestPermissionsResult is not called.

This is the manifest:

</manifest>

Here are some tidbits from the gradle file:

compileSdkVersion 23
    buildToolsVersion '21.1.2'

    defaultConfig {
        minSdkVersion 12
        targetSdkVersion 23
    }

This is in a FragmentActivity, don't know if that matters. I have uninstalled the app and run it so there should be no permissions already accepted. This is on a Nexus 7 running 6.0.

Answer 1

Why not try this library: https://github.com/tajchert/Nammu. It worked for me.

Nammu.askForPermission(activity, String[] permissions, new PermissionCallback() {
    @Override
    public void permissionGranted() {}

    @Override
    public void permissionRefused() {}
});

EDIT
I created a library that encapsulates the whole thing and makes it much more easier. It also shows a customisable explanation dialog before the actual request.

Use this library: https://github.com/ayz4sci/permissionHelper

Usage:
To perform an action that requires Android permission, call permissionHelper.verifyPermission. It accepts the following parameters:

String [] - description of each permission required, this will be displayed to the user in the explanation dialog.
String [] - an array of Manifest permissions
PermissionCallback - you put the actions you want to perform when permission is granted or rejected.
See example below:

permissionHelper.verifyPermission(
    new String[]{"dial this number", "take picture"},
    new String[]{Manifest.permission.CALL_PHONE, Manifest.permission.CAMERA}, 
    new PermissionCallback() {
        @Override
        public void permissionGranted() {
            //action to perform when permission granteed
        }

        @Override
        public void permissionRefused() {
            //action to perform when permission refused
        }
    }
);
