Description

I'm not sure if this issue is GmsCore related.
CityMapper v6.22 is crashing on my device.

Logcat: https://gist.github.com/pihug12/49504ca314ffda96993feb3f5a76098a
"java.lang.IllegalArgumentException: provider doesn't exist: gps"

My device doesn't have a GPS chip. But WiFi geolocalisation should work.

  • Device: Amazon Kindle Fire HD 7" (tate)
  • OS: CyanogenMod 12.1 (Android 5.1.1)
  • microG Services Core: 0.2.4-103
  • Xposed + FakeGapps module
  • FakeStore
  • MozillaNlpBackend + NominatimNlpBackend

CityMapper v6.22: ApkPure.com

Research direction

Start with the linked Logcat and reproduce CityMapper v6.22 on the specified Kindle Fire configuration without a GPS chip. No source file or test is identified in the issue, so trace the provider-doesn't-exist exception into GmsCore's location handling; done means CityMapper no longer crashes and WiFi geolocation remains usable.
