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);
}
