@bhaktiugp Could you try using the latest SDK version and see if you can reproduce the issue? Also, did you add the correct location permissions for your android export.

More details on how to reproduce the issue would be super helpful .

Trying to use "World-scale AR manual alignment" with android application, but faced same issue. Any help?

Same Problem here. If I add the Android Native location provider, the above class can't get loaded and the location is not updating

[janweigel]

As a workaround to the problem I could get the classes loaded successfully if the minify options in the android player settings of unity are disabled. As soon as I enable Minify (set the checkbox for Release or Debug) the classes are not found anymore. I hope this get's fixed in a future version as of course we would prefer to use Minify and Mapbox makes this impossible.

Just letting you know I'm having the same issue. Thank you @janweigel for the workaroud. Seems to be working when turning off the minify options.

Here's the log:
