Thread run（）函数中的Android内存泄漏

Question

我有这个从服务运行的线程。运行循环运行大约15分钟没有问题。之后 - 我的GC因内存泄漏而疯狂，然后该功能再也不能正常工作了。

我已经使用DDMS分配跟踪器来查找泄漏，并且泄漏似乎在input = in.readLine();行内。我真的不知道如何解决它，但这是我的代码，堆栈跟踪和Allocation Tracker快照：

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);
}
