具有定时Embarcadero的德尔福XE10的Android服务 [英] embarcadero delphi XE10 android service with a timer
问题描述
我发展我的第一个服务,我有烦恼。我使用作为基础这个例子从Embarcadero的:
I am developing my first service and I am having troubles. I am using as basis this example from embarcadero:
<一个href=\"http://docwiki.embarcadero.com/$c$cExamples/Seattle/en/FMX.Android_Notification_Service_Sample\" rel=\"nofollow\">http://docwiki.embarcadero.com/$c$cExamples/Seattle/en/FMX.Android_Notification_Service_Sample
在服务启动时将消息发送到服务器,它工作正常。我只需要删除UDPclient的形式和我加code的一条线。这是code和的它的工作原理:的
When the service starts I send a message to a server and it works fine. I only need to drop the UDPclient on the form and I add one line of code. This is the code and it works:
unit NotificationServiceUnit;
interface
uses
System.SysUtils,
System.Classes,
System.Android.Service,
AndroidApi.JNI.GraphicsContentViewText,
Androidapi.JNI.Os, System.Notification, IdBaseComponent, IdComponent,
IdUDPBase, IdUDPClient;
type
TNotificationServiceDM = class(TAndroidService)
NotificationCenter1: TNotificationCenter;
IdUDPClient1: TIdUDPClient;
function AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags, StartId: Integer): Integer;
private
{ Private declarations }
FThread: TThread;
procedure LaunchNotification;
public
{ Public declarations }
end;
var
NotificationServiceDM: TNotificationServiceDM;
implementation
{%CLASSGROUP 'FMX.Controls.TControl'}
uses
Androidapi.JNI.App, System.DateUtils;
{$R *.dfm}
function TNotificationServiceDM.AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags,
StartId: Integer): Integer;
begin
IdUDPClient1.Send('I am a service');
LaunchNotification;
JavaService.stopSelf;
Result := TJService.JavaClass.START_STICKY;
end;
procedure TNotificationServiceDM.LaunchNotification;
var
MyNotification: TNotification;
begin
MyNotification := NotificationCenter1.CreateNotification;
try
MyNotification.Name := 'ServiceNotification';
MyNotification.Title := 'Android Service Notification';
MyNotification.AlertBody := 'RAD Studio 10 Seattle';
MyNotification.FireDate := IncSecond(Now, 8);
NotificationCenter1.ScheduleNotification(MyNotification);
finally
MyNotification.Free;
end;
end;
end.
所以,我只加了 IdUDPClient1.Send(我是一个服务');
当我想用一个定时器来重复信息发送到服务器的问题出现了。所以我滴计时器的假的形式,计时器是活动的,并分别5秒期间将消息发送到服务器。
The problem arises when I want to use a timer to send repetitively a message to the server. So I drop a timer to the "false" form, timer is active, and each 5 seconds sends a message to the server.
新的code是:
unit NotificationServiceUnit;
interface
uses
System.SysUtils,
System.Classes,
System.Android.Service,
AndroidApi.JNI.GraphicsContentViewText,
Androidapi.JNI.Os, System.Notification, IdBaseComponent, IdComponent,
IdUDPBase, IdUDPClient, FMX.Types;
type
TNotificationServiceDM = class(TAndroidService)
NotificationCenter1: TNotificationCenter;
IdUDPClient1: TIdUDPClient;
Timer1: TTimer;
function AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags, StartId: Integer): Integer;
private
{ Private declarations }
FThread: TThread;
procedure LaunchNotification;
public
{ Public declarations }
procedure Timer1Timer(Sender: TObject);
end;
var
NotificationServiceDM: TNotificationServiceDM;
implementation
{%CLASSGROUP 'FMX.Controls.TControl'}
uses
Androidapi.JNI.App, System.DateUtils;
{$R *.dfm}
function TNotificationServiceDM.AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags,
StartId: Integer): Integer;
begin
IdUDPClient1.Send('I am a service');
LaunchNotification;
JavaService.stopSelf;
Result := TJService.JavaClass.START_STICKY;
end;
procedure TNotificationServiceDM.LaunchNotification;
var
MyNotification: TNotification;
begin
MyNotification := NotificationCenter1.CreateNotification;
try
MyNotification.Name := 'ServiceNotification';
MyNotification.Title := 'Android Service Notification';
MyNotification.AlertBody := 'RAD Studio 10 Seattle';
MyNotification.FireDate := IncSecond(Now, 8);
NotificationCenter1.ScheduleNotification(MyNotification);
finally
MyNotification.Free;
end;
end;
procedure TNotificationServiceDM.Timer1Timer(Sender: TObject);
begin
IdUDPClient1.Send('I send from the timer');
end;
end.
在这种情况下,应用程序无法启动的服务和它不响应。任何帮助吗?感谢很多提前。
In this case, the Application cannot start the service and it does not respond. Any help? Thanks a lot in advance.
推荐答案
我发现定时器不上的服务西雅图10工作,它似乎对服务不作任何FMX人员的工作。
I found timers do not work on services on Seattle 10. and it seems no fmx staff work on services.
我现在用的是睡眠线程(x)的模拟定时器。我打开可以重复每个任务的线程。例如:
What I am using are threads with sleep(x) to simulate a timer. I open a thread for each task to be repeated. For example:
procedure Thinfinito;
var
atask : Itask;
begin
atask := Ttask.create(procedure()
var
hacer: boolean;
ahora : Tdatetime;
begin
hacer := false;
REPEAT
begin
sleep(10000);
ahora := now;
v.IdUDPClient1.Send(TimeToStr(ahora)+' = soy el servicio');
end;
UNTIL hacer = true;;
end);
atask.Start;
end;
此线程从服务将消息发送到一个服务器的每个10秒。没有尽头......好吧,直到服务被杀害。我的工作这一点。
This thread sends a message to a server from the service each 10 seconds. No end...well until the service is killed. I am working on that.
