问题描述
我必须将数据上传到服务器.我正在使用与我的应用程序在同一进程上运行的服务.我应该使用单独的线程进行上传过程还是应该使用 AsyncTask 将数据上传到服务器?
I have to upload data to a server. I am using a service that is running on the same process as my application. Should I use a Separate thread for upload process or Should I use a AsyncTask to upload data to server ?
更具体地说，我可以在服务类中使用 AsyncTask 吗?我应该使用它吗?此服务应始终在内存中运行，以便每 5 秒向服务器发送一次数据.
More specifically can I use AsyncTask inside a service class ? And should I use it ? This service should always be running in memory in order to send data to the server every 5 seconds.
推荐答案
是的，你可以，下面的代码将每 5 秒运行一次.使用您的常规连接代码发送部分.
Yes you can, the below code will run every 5 seconds. Use your regular connection code for sending part.
public class AsyncTaskInServiceService extends Service {
public AsyncTaskInServiceService() {
super("AsyncTaskInServiceService ");
}
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
}
@Override
protected void onHandleIntent(Intent intent) {
final Timer t = new Timer();
t.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
//Connect to database here
try {
} catch (JSONException e) {
e.printStackTrace();
}
}
}, 0, 5000);
}
}
