Even though Android documentation insists heavily on not using background location updates, my app really needs them, so I updated everything to request permissions properly and abide by the new rules. Now once I have ACCESS_BACKGROUND_LOCATION permission granted, I do the following to request background location updates from within my initial Fragment:
private fun configureBackgroundLocationTracking() {
fusedLocationClient.requestLocationUpdates(createLocationRequest(), getPendingIntent())
}
private fun createLocationRequest(): LocationRequest {
return LocationRequest.create().apply {
interval = 20000
fastestInterval = 10000
priority = LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY
}
}
private fun getPendingIntent(): PendingIntent {
val intent = Intent(requireContext(), LocationUpdatesBroadcastReceiver::class.java)
return PendingIntent.getBroadcast(
requireContext(),
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT
)
}
In my AndroidManifest, I declare the BroadcastReceiver like so:
<receiver android:name=".LocationUpdatesBroadcastReceiver"
android:exported="true"
android:permission="android.permission.ACCESS_BACKGROUND_LOCATION">
<intent-filter>
<action android:name="com.herontrack.LOCATION_UPDATE" />
</intent-filter>
</receiver>
And here is the code of my LocationUpdatesBroadcastReceiver:
class LocationUpdatesBroadcastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
val result = LocationResult.extractResult(intent)
if (result != null) {
val location = result.lastLocation
if (location != null) {
Log.d(TAG, "Received location update: $location")
}
}
}
companion object {
private const val TAG = "LUBroadcastReceiver"
}
}
And the log instruction inside onReceive() sends the log to a remote logger (Bugfender).
When my app is in the foreground, everything seems to work, I can see the logs.
But when it is in the background, no more updates.
I double checked the permission and I'm sure that when I register the BroadcastReceiver, ACCESS_BACKGROUND_LOCATION is granted.
I'm running on a Samsung S9 with Android 10.
Did I forget something? Is there a problem with doing all of that from within a Fragment?
