Android services and TLocationSensor

Hi,
to include System.Sensors (TLocationSensor) or FMX.Types (TTimer) in Uses clause in service, this is not created.
the example given in Delphi (BeaconServiceDemo) works.
but if you change Uses of BeaconServiceUnit.pas for:
uses System.SysUtils, System.Classes, System.Android.Service, AndroidApi.JNI.GraphicsContentViewText, Androidapi.JNI.Os, System.Beacon, System.Notification, System.Beacon.Components, System.Sensors;
does not work. The service is not created.
to test, changed the following routine:
implementation

{%CLASSGROUP 'FMX.Controls.TControl'}

{$R *.dfm}

uses
Androidapi.JNI.App,
Androidapi.JNIBridge,
AndroidApi.JNI.Media;
function TBeaconServiceDM.AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags,
StartId: Integer): Integer;

procedure Sound(ADuration: Integer);
var
Volume: Integer;
StreamType: Integer;
ToneType: Integer;
ToneGenerator: JToneGenerator;
begin
Volume := TJToneGenerator.JavaClass.MAX_VOLUME;
StreamType := TJAudioManager.JavaClass.STREAM_ALARM;
ToneType := TJToneGenerator.JavaClass.TONE_DTMF_0;
ToneGenerator := TJToneGenerator.JavaClass.init(StreamType, Volume);
ToneGenerator.startTone(ToneType, ADuration);
end;

begin
sound(100); // with system.sensors, not play the sound and message "The BeaconServiceApp stopped"[/b]
Beacon1.Enabled := True;
Result := TJService.JavaClass.START_STICKY;
end;

my configuration:
Delphi 10 Seattle Update 1
android 4.4.4
Does anyone know what can it be?
