Mapbox: Failed to obtain last location update

[ctlmjg]

I created an Android App following this tutorial: https://docs.mapbox.com/android/maps/examples/show-a-users-location/

I did everything exactly as it says in the tutorial. I can open the map but when the app tries to give my current location I'm getting this error:

D/Mbgl-LocationComponentCompassEngine: Rotation vector sensor not supported on device, falling back to accelerometer and magnetic field. E/Mbgl-LocationComponent: Failed to obtain last location update java.lang.Exception: Last location unavailable at com.mapbox.android.core.location.MapboxFusedLocationEngineImpl.getLastLocation(MapboxFusedLocationEngineImpl.java:40) at com.mapbox.android.core.location.LocationEngineProxy.getLastLocation(LocationEngineProxy.java:25) at com.mapbox.mapboxsdk.location.LocationComponent.setLastLocation(LocationComponent.java:1315) at com.mapbox.mapboxsdk.location.LocationComponent.onLocationLayerStart(LocationComponent.java:1134) at com.mapbox.mapboxsdk.location.LocationComponent.enableLocationComponent(LocationComponent.java:1248) at com.mapbox.mapboxsdk.location.LocationComponent.setLocationComponentEnabled(LocationComponent.java:502) at com.example.android.myapplication.MainActivity.enableLocationComponent(MainActivity.java:74) at com.example.android.myapplication.MainActivity.access$000(MainActivity.java:25) at com.example.android.myapplication.MainActivity$1.onStyleLoaded(MainActivity.java:56) at com.mapbox.mapboxsdk.maps.MapboxMap.notifyStyleLoaded(MapboxMap.java:845) at com.mapbox.mapboxsdk.maps.MapboxMap.onFinishLoadingStyle(MapboxMap.java:205) at com.mapbox.mapboxsdk.maps.MapView$MapCallback.onDidFinishLoadingStyle(MapView.java:1178) at com.mapbox.mapboxsdk.maps.MapChangeReceiver.onDidFinishLoadingStyle(MapChangeReceiver.java:194) at com.mapbox.mapboxsdk.maps.NativeMapView.onDidFinishLoadingStyle(NativeMapView.java:1040) at android.os.MessageQueue.nativePollOnce(Native Method) at android.os.MessageQueue.next(MessageQueue.java:143) at android.os.Looper.loop(Looper.java:122) at android.app.ActivityThread.main(ActivityThread.java:5930) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1405) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1200) D/SensorManager: registerListener :: 0, K2HH Acceleration , 100000, 0, E/SensorManager: sensor or listener is null

Hey @catarinarpds, thanks for reaching out!

The only issue I'm seeing here is that you weren't able to obtain a location update. This is just a log, not an actual crash.

Would you be able to provide which version of the Maps SDK have you used and what device have you tested on?

Meanwhile, I'm transferring this issue to out telemetry repository.

@catarinarpds any updates? also can you share your project's app/build.gradle file? thanks!

Sorry I forgot to answer ! I guess the phone I used to run the app is not updated.

I'm also having this error

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.mapbox.mapboxsdk.maps.MapView.onSaveInstanceState(android.os.Bundle)' on a null object reference when I click in the Recent Apps Button in my phone... Can u help me?

@nkukday please review alongside #419

Valid: https://github.com/mapbox/mobile-telemetry/issues/458

From #419

@alfwatt we're pretty much adhering to google apis behavior with the only diff: if last location isn't available in google they return null and we throw an exception. Perhaps we need to document api signature to set expectation.
