我有一个在信息亭上运行的应用程序。大约 8 小时后，应用程序“消失”。“消失”是指它不再是最顶级的应用程序并且桌面显示。该应用程序仍在运行，因为它在我单击“切换应用程序”按钮后出现。

我试图弄清楚为什么会这样。我添加了

protected void onDestroy() {
    Log.e("here", "onDestroy");
    super.onDestroy();
}

protected void onPause() {
    Log.e("here", "onPause");
    super.onPause();
}


protected void onStop() {
    Log.e("here", "onStop");
    super.onStop();
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    Log.e("here", "onCreate");

    super.onCreate(savedInstanceState);
    webView = (WebView) findViewById(R.id.webView);

    Thread.setDefaultUncaughtExceptionHandler(
                new Thread.UncaughtExceptionHandler() {
                    public void uncaughtException(Thread thread, Throwable ex) {
                    };
                }
        );

当我收到错误报告时，我就是这样想的，我会看看发生了什么。但是，日志中没有出现任何内容。

有谁知道为什么在使用大约几个小时后窗口被隐藏了？有什么我可以用仪器来解决这个问题的系统吗？
