Location activities report a missing class #1222

All location activities report a missing LocationResult class with each location update:

The activities continue to work as expected, so I suspect a dependency clash.

The text was updated successfully, but these errors were encountered:

I've also seen this log cat message in a weekend side project that uses the Maps SDK and shows the device location puck LocationComponent .

cc @harvsu @nkukday in case ya'll have seen this before and/or if this message comes from something upstream from the Maps SDK in https://github.com/mapbox/mapbox-events-android/

botanegg · 2019-11-12T19:09:30Z

I fixed it for me by adding implementation 'com.google.android.gms:play-services-location:17.0.0' into my build.gradle

Is this still an issue in the latest SDK? I can't simply just add the dependency com.google.android.gms:play-services-location because this causes the getBestProvider method to incorrectly assume play services is installed.
