I'm using HERE Maps SDK and after calling navigationManager.startNavigation() I'm getting this exception in logs, SOMETIMES:

LocationManager: [LocationManager] requestLocationUpdates(), 

    java.lang.RuntimeException

        at android.location.LocationManager.requestLocationUpdates(LocationManager.java:1013)

        ...

Looks like the SDK is catching it because try/catch doesn't get it and nothing crashes, response is still NavigationManager.Error.NONE but navigation doesn't start.

Not sure what triggers it but the app may work fine for days and then this shows up and for few minutes or hours I can't get the navigation to work.

This exception occurs only sometimes, when the app tries to get a location from the SDK, but then it's for every single request for a certain time.

Has anybody encountered this ? I have no idea how to handle this other than setting a timer to check whether I'm getting any location updates.

Documentation for LocationManager describes that requestLocationUpdates throws two types of exceptions - IllegalArgumentException and SecurityException.
Maybe some vendor added its own undocumented logic that throws RuntimeException.

As a dirty fix, you could try stop/start requestLocationUpdates like that:

PositioningManager.start(LocationMethod.NETWORK); // will stop updates for LocationManager.GPS_PROVIDER

PositioningManager.start(LocationMethod.GPS); // will stop updates for LocationManager.NETWORK_PROVIDER

PositioningManager.start(LocationMethod.GPS_NETWORK); // will start updates for both

Secondly, if you have appropriate permission, you can try setting HERE location data source, like that:

//SDK will use custom algorithm to calculate device location

//and Android's LocationManager will not be used

PositioningManager.setDataSource(LocationDataSourceHERE.getInstance()); 

If you provide more info, like device, preconditions when it is happening, do other apps like Google Map can detect your location etc, maybe then it can be fixed.
