问题
I am using SettingsApi and FusedLocationProvider to upgrade Gps settings and getting location updates, I want High accuracy location updates for that I am showing Turn on gps dialog using SettingsApi to upgrade GPS settings to High Accuracy but in some devices (like Mi and Gionee) even if the user has clicked OK button in Turn On Gps Dialog I am getting RESULT_CANCELED on onActivityResult while everything is working perfectly fine in other devices like Motorola, Lenovo
When User is Clicking On in Turn On Gps dialog
- If Gps is Off then it is turned On and gets set to Device Only Mode (Gps Only Mode)
- If Gps is On then Gps is turned Off and I am getting RESULT_CANCELED on
onActivityResultin both the cases
Here's My Code

回答1:
There is no issue with library itself, the problem is with an App called FusedLocationProvider go to Settings -> Intstalled Apps -> FusedLocationProvider -> Clear Cache & Data now your app will work Just fine.
WorkAround #1: You can opt for
LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY- Faster Location Updates but location accuracy may be lowLocationRequest.PRIORITY_LOW_POWER- Slower or maybe No Location Updates (if indoor or underground)
WorkAround #2: Redirect User to Settings Page
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, REQUEST_UPDATE_GPS_SETTINGS_MANUALLY);
