android - Android - 递归调用处理程序时的垃圾收集器错误

Question

我正在努力不断地做一份工作。对于这项工作，我正在使用处理程序并以恒定的时间间隔递归地调用此处理程序。我的代码在 Android 版本 4.3 的三星 Galaxy Note 2 中运行，但不能在 Android 版本 4.4.2 的 Nexus 5 中运行。我被这个问题困住了。我正在输入代码和错误日志，请帮忙。祝你有美好的一天。（我正在简化代码，因此您可以轻松分析，但是如果您愿意，我可以在这里编写所有代码。）（另外，由于它的大小，我没有写所有的错误日志。）

代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tram);

    some initializations...

    runnable = new Runnable() {

        public void run() {
            if (!isMapDataLoading) {
                // update the trams' markers
                loadMapDataIfNeeded(true);
            }
            handler.postDelayed(this, handlerDelayInterval);
        }
    };

    // some settings...
}

@Override

    super.onResume();
    setUpLocationClientIfNeeded();
    locationClient.connect();
    if (!isHandlerRun) {

        isHandlerRun = true;
    }

Answer 1

我意识到这个问题的发生是因为我谈到的 Nexus 5 具有 ART 的运行时。此外，“ART”一词出现在错误日志中。我已将 Nexus 5 的运行时更改为 Dalvik，问题已消失。我认为当前的 ART 实现存在错误。

Answer 2

这是否解决了它并完成了您的需要？

    runnable = new Runnable() {
        @Override
        public void run() {
            if (!isMapDataLoading) {
                // update the trams' markers
                loadMapDataIfNeeded(true);
            }
            try {
               Thread.sleep(handlerDelayInterval);
            } catch (InterruptedException ignore){}
            run();
        }
    };

你要无限循环吗？
