我有这个从服务运行的线程。run 的循环运行大约 15 分钟没有问题。在那之后 - 我的 GC 因内存泄漏而发疯，然后该功能就不能再正常工作了。

我已经使用 DDMS Allocation Tracker 来查找泄漏，并且似乎泄漏在input = in.readLine();线路内。我真的不知道如何解决它，但这是我的代码、堆栈跟踪和分配跟踪器快照：

代码：

@Override
public void run() {
    startKeepAliveTimer();  
    try {
            socket = new Socket(host, port);
            if (socket != null)
            {
                Log.i("ServerConnection", "Server connection opened");
                this.app.setConnectedToServer(true);
                serverManager.loginToServer();
            }
            else
                app.setConnectedToServer(false);                
            InputStreamReader inputStreamReader = new InputStreamReader(socket.getInputStream());
            BufferedReader in = new BufferedReader(inputStreamReader);
            String input;
            while (app.isConnectedToServer()) 
            {
                app.getFacebookManager().refreshAccessToken();                                      
                input = in.readLine();
                if (input != null)
                {
                    lastOnline = System.currentTimeMillis();
                    input = input.trim();
                    input = app.decrypt(input);
                    Log.e("Server Reponse", input);                 
                    serverManager.processData(app.convertToJSONObject(input));
                }
            }
        } catch (IOException e) {
            Log.e("ServerConnection", e.toString());
        }           

        Log.i("ServerConnection", "Server connection closed");
}



private void startKeepAliveTimer() {
    Timer timer = new Timer("keepAlive", true);
    timer.scheduleAtFixedRate(new TimerTask() {         
        @Override
        public void run() {
            keepAlive();                
        }
    }, 0, keepAlive);
}
