I have an app which polls a remote server by sending to it its cache GPS location. Sometimes a remote server will ask for live location and an app must send it to it.
object MyLocationManager {
val providers = listOf(
LocationManager.GPS_PROVIDER,
"fused",
LocationManager.NETWORK_PROVIDER,
LocationManager.PASSIVE_PROVIDER,
)
fun getCached(ctx: Context, locationManager: LocationManager): Location? {
for (provider in providers) {
when (provider) {
"fused" -> {
val fusedLocationClient =
LocationServices.getFusedLocationProviderClient(ctx)
val fusedLocationTask = fusedLocationClient.lastLocation
val fusedLocation = getTaskResult(fusedLocationTask)
if (fusedLocation != null) {
return fusedLocation
}
}
else -> {
if (locationManager.isProviderEnabled(provider)) {
val lastKnownLocation = locationManager.getLastKnownLocation(provider)
Log.d(
TAG,
"Provider: $provider, Last Known Location: $lastKnownLocation"
)
if (lastKnownLocation != null) {
return lastKnownLocation
}
}
}
}
}
return null
}
fun getLive(ctx: Context, locationManager: LocationManager): Location? {
val locationListener = object : LocationListener {
override fun onLocationChanged(location: Location) {
//This works correctly!
//
//1) how to save its result? How to save it into cache?
//2) or how to return it from here?
Log.d(TAG, "onLocationChanged: ${location.latitude}, ${location.longitude}")
stopLocationUpdates()
}
private fun stopLocationUpdates() {
val fusedLocationClient = LocationServices.getFusedLocationProviderClient(ctx)
try {
// Stop location updates
fusedLocationClient.removeLocationUpdates(locationCallback)
Log.d(TAG, "Location updates stopped")
} catch (e: SecurityException) {
Log.e(TAG, "SecurityException while stopping location updates: ${e.message}")
}
}
private val locationCallback = object : LocationCallback() {
override fun onLocationResult(locationResult: LocationResult) {
super.onLocationResult(locationResult)
val location = locationResult.lastLocation
if (location != null) {
onLocationChanged(location)
} else {
Log.e(TAG, "Received null location in onLocationResult")
}
}
}
}
for (provider in providers) {
when (provider) {
LocationManager.GPS_PROVIDER -> {
//obsolete, in the last Android versions
val _locationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(0)
.setFastestInterval(0)
val fusedLocationClient = LocationServices.getFusedLocationProviderClient(ctx)
val locationResult: Task = fusedLocationClient.getLocationAvailability()
if (!Tasks.await(locationResult).isLocationAvailable) {
return null
}
val locationTask: Task = fusedLocationClient.getCurrentLocation(
LocationRequest.PRIORITY_HIGH_ACCURACY,
null
)
return Tasks.await(locationTask)
}
"fused" -> {
val apiAvailability = GoogleApiAvailability.getInstance()
val resultCode = apiAvailability.isGooglePlayServicesAvailable(ctx)
if (resultCode == ConnectionResult.SUCCESS) {
val fusedLocationClient = LocationServices.getFusedLocationProviderClient(ctx)
val fusedLocationTask = fusedLocationClient.lastLocation
val fusedLocation = getTaskResult(fusedLocationTask)
if (fusedLocation != null) {
return fusedLocation
}
} else {
Log.w(TAG, " Google Play Services aren't available, can't use fused")
}
}
else -> {
if (locationManager.isProviderEnabled(provider)) {
locationManager.requestSingleUpdate(
provider,
locationListener,
Looper.getMainLooper()
)
val lastKnownLocation = locationManager.getLastKnownLocation(provider)
if (lastKnownLocation != null) {
return lastKnownLocation
}
}
}
}
}
return null
}
}
An issue is that the code for obtaining GPS location doesn't work properly. Firstly, I don't know whether the approach in the code is correct. Secondly, I don't know how to properly to return the GPS coordinates from a callback -- see the comments. Thirdly, I don't know how to force it to store the latest coordinates that it's obtained into cache.
And there're some functions that's been derprecated in the latest versions of Android, particularly in Android 10.
How to do all of this?
My device is rooted.
I have a rooted Android 10. And I've written a service (off the class Service) which I want to run under too, in background. A service uses a microphone and location. It's written in Kotlin.
I've not found any information of how to run a service on a rooted device under root. I've found some, about running some commands in a service (code) itself under root, though, but it may be only a part of what I need.
How to do it?
Essentially, I want my service to run forever, with elevated preveligies, get itself restarted if it fails, gets killed by Android.
Also, I've tried to copy it into /system
and /system/init
directories, but I haven't been able to, due to "read-only file system". Nor have I been able to remount it to make it writteable. I've managed to make the /
writteable, but it didn't allow me to copy my service in /system
nonetheless.

I connect to a WireGuard installed on my VPS. Then I go to a random VPN service marketing page on which I'll discover that my DNS leaks. And which is correct because I've specified DNS = 1.1.1.1 in [Interface]
for all the Peers.
In order to avoid DNS leakadge, do I have to a) run DNS server on the a VPS -- along with WireGuard, and b) use this one and only it, instead of 1.1.1.1
?
But if so, how will this possibly work?
[Peer]
PublicKey = [....;....]
PresharedKey = [......]
Endpoint = wg.my_domain123.com:51820
In order to resolve Endpoint
of my VPS to begin with, other DNS server will have to be used -- by IP. But there'll be none because I'll use a DNS on my VPS instead of 1.1.1.1
. In other words, it'll be a circular dependency.
In a third-party project, in the models, I've encountered functions like this:
def changeset(model \\ %__MODULE__{}, params) do
model
|> cast(params, @required_fields ++ @optional_fields)
|> validate_required(@required_fields)
end
How can a function have a default argument which is both a) first and b) followed by a mandatory one?
What's interesting, they work properly.
A docker, when run for the 1st time, won't do so:
$ docker-compose -f docker-compose.local.yml up -d
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.config-hash%22%3Atrue%2C%22com.docker.compose.project%3Doxygen%22%3Atrue%7D%7D": dial unix /var/run/docker.sock: connect: permission denied
I'll run this command
$ sudo setfacl --modify user:user1:rw /var/run/docker.sock
which will resolve the issue. However, after a reboot, the issue will arise again.
Why? How to make the change permanent?
