Recently I've been trying to implement the logic in order to get Location Updates from a FusedLocationProviderClient using Work Manager, every 15 mins (as that's the minimum background execution delay). However requestLocationUpdates() function from FusedLocationProviderClient is failing every 15 minutes, and I cannot get success result task from it, I'm always getting failed result. And when I print the exception from fusedlocationproviderclient it just prints "null"? Any help?
Fragment:
private fun addWorker(){
val workRequest = PeriodicWorkRequestBuilder<MyWorker>(15, TimeUnit.MINUTES)
.build()
val workManager = WorkManager.getInstance(requireContext())
workManager.enqueueUniquePeriodicWork(
"MyMainWorker",
ExistingPeriodicWorkPolicy.KEEP,
workRequest
)
}
Worker
class MyWorker(context: Context, wp: WorkerParameters) :
Worker(context, wp) {
private val LOCATION_UPDATE_INTERVAL = TimeUnit.MINUTES.toMillis(4)
private val LOCATION_FASTEST_UPDATE_INTERVAL = TimeUnit.MINUTES.toMillis(2)
private var ctx: Context = context
override fun doWork(): Result {
return if (getLocationUpdate()) {
Log.d("MyWorker", "SUCCESS")
Result.success()
} else {
Log.d("MyWorker", "FAILURE")
Result.failure()
}
}
@SuppressLint("MissingPermission")
private fun getLocationUpdate(): Boolean {
val fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(ctx)
val locationCallback = object : LocationCallback() {
override fun onLocationResult(result: LocationResult?) {
super.onLocationResult(result)
result?.locations?.let { locations ->
for (location in locations) {
Log.d("MyWorker", "NEW Location: $location")
}
}
}
}
val locationRequest = LocationRequest().apply {
interval = LOCATION_UPDATE_INTERVAL
fastestInterval = LOCATION_FASTEST_UPDATE_INTERVAL
priority = LocationRequest.PRIORITY_HIGH_ACCURACY
}
val result = fusedLocationProviderClient.requestLocationUpdates(
locationRequest,
locationCallback,
Looper.getMainLooper()
)
Log.d("MyWorker", result.exception?.message.toString())
Log.d("MyWorker", result.exception?.cause.toString())
Log.d("MyWorker", result.exception.toString())
return result.isSuccessful
}
Error
