[android] How can I enable or disable the GPS programmatically on Android?

This one works for me.

It is simpler then Rj0078's answer in this question (https://stackoverflow.com/a/42556648/11211963), but that one is worked as well.

It shows a dialog like this:

(Written in Kotlin)

    googleApiClient = GoogleApiClient.Builder(context!!)
        .addApi(LocationServices.API).build()
    googleApiClient!!.connect()
    locationRequest = LocationRequest.create()
    locationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    locationRequest!!.interval = 30 * 1000.toLong()
    locationRequest!!.fastestInterval = 5 * 1000.toLong()

    val builder = LocationSettingsRequest.Builder()
        .addLocationRequest(locationRequest!!)
    builder.setAlwaysShow(true)

    result =
       LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
    result!!.setResultCallback { result ->
        val status: Status = result.status
        when (status.statusCode) {
            LocationSettingsStatusCodes.SUCCESS -> {
               // Do something
            }
            LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
                try {
                    startResolutionForResult(),
                    status.startResolutionForResult(
                        activity,
                        REQUEST_LOCATION
                    )
                } catch (e: SendIntentException) {
                }
            LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
                // Do something
            }
        }
    }
