所有内容都在标题中。
在官方文档中,声明Note that services, like other application objects, run in the main thread of their hosting process
和AsyncTask只有在UIThread中执行时才能工作。
那么在服务类中使用AsyncTask是可能的吗?
我正在尝试这样做,但是我总是得到相同的错误
05-01 18:09:25.487: ERROR/JavaBinder(270): java.lang.ExceptionInInitializerError
..。
05-01 18:09:25.487: ERROR/JavaBinder(270): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
是我做错了什么,还是这是不可能的?
下面是我的Service类的代码
package com.eip.core;
import android.app.Service;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
public class NetworkService extends Service {
private final INetwork.Stub mBinder = new INetwork.Stub() {
@Override
public int doConnect(String addr, int port) throws RemoteException {
new ConnectTask().execute("test42");
return 0;
}
};
@Override
public IBinder onBind(Intent arg0) {
return mBinder;
}
private class ConnectTask extends AsyncTask<String, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
Log.i("OnPreExecute()", "");
}
@Override
protected Void doInBackground(String... arg0) {
Log.i("doInBackground()", "");
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
Log.i("OnPostExecute()", "");
}
}
}
