Android 服务被 ANR 杀死

Question

我的应用程序中有一个服务(由一个线程创建)，我在里面创建了另一个线程，它是一个 TCP 服务器。在启动线程(并完全工作、接收和处理收到的包)后不久，服务被“超时执行服务”和我的服务中的 ANR 终止。

这是我的服务代码和执行所有工作的线程:

public class Android_Wifi_Service extends Service {

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, flags, startId);
        handleStart();
        return START_STICKY;
    }

    private void handleStart() {
        Server server=new Server(this);
        new Thread(server).run();
    }


    @Override
    public void onDestroy(){
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

}

这是我的主题:

public class Server implements Runnable {
    private boolean end=false;
    private Context context;

    public Server(Context _context){
        this.context=_context;
    }

    @Override
    public void run() {
        try {
            ServerSocket ss= new ServerSocket(5552);

            while(!end){
                //wait for connection
                System.out.println("Server Waiting connection");
                Socket s=ss.accept();
                SenderMessage msg=null;
                // connected 
                InputStream is = s.getInputStream();
                ObjectInputStream obj=new ObjectInputStream(is);
                try {
                    msg= ( SenderMessage ) obj.readObject();
                } catch (Exception e) {
                    Log.e("Message Receive Error", e.toString());
                }
                obj.close();
                is.close();
                s.close();
                if(msg!=null){
                    // do somethings
                }
            }

        } catch (IOException e) {
            Log.e("Messages Server", e.toString());
        }

    }   
}

这是 logcat:

谁能帮帮我？

您不会通过调用 run() 来启动 Thread。您通过调用 start() 启动一个 Thread。现在，您只是在主应用程序线程上调用您自己的 Thread 的 run() 方法。
