Android Question GPS location background

[stevenindon]

Hello all,
I have been building an app for my customer - tracking user location in the background. Followed example app by erel :

Background location tracking

Simple example of a foreground service that keeps the process running in the background. The current location is shown in the persistent notification. The app starts at boot and theoretically should run all the time. It also schedules itself to run with StartServiceAt. This can help in cases...

www.b4x.com

The application runs non stop on android 9 (Samsung) sending user location to server....but rapidly stopped on android 12 after phone idle for 20 minutes (Oppo). Will continue for a short while again only when i wakes up phone. (* I puts beeping sound when upload location to server)

Below are GPS request permissions :
1) rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
2) rp.CheckAndRequest("android.permission.ACCESS_BACKGROUND_LOCATION") - *Phone1.SdkVersion >= 29
3) JavaObject1.RunMethod("isIgnoringBatteryOptimizations", Null) * Ignore battery optimization


Menifest :

AddPermission(android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)
AddManifestText(<uses-feature android:name="android.hardware.location.gps"/>)
SetServiceAttribute(TWP_GPSService, android:foregroundServiceType, "location")
AddPermission(android.permission.ACCESS_FINE_LOCATION)
AddPermission(android.permission.ACCESS_BACKGROUND_LOCATION)

Did i miss something? Please help..

Check the device settings. Some manufacturers add options to whitelist apps. This is not something that you can do programmatically.
