嗨,我已经开发了 android phonegap 应用程序,当显示对话框并且屏幕方向发生变化时,在 logcat 中显示错误。如何解决这个问题
这是我的 logcat 错误:
E/WindowManager(5759): Activity com.example.Service.NotificationAlert has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@412c93c0 that was originally added here
E/WindowManager(5759): android.view.WindowLeaked: Activity com.example.Service.NotificationAlert has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@412c93c0 that was originally added here

请告诉我解决方案。在此先感谢。
这是我的代码:
AlertDialog alertDialog = new AlertDialog.Builder(NotificationAlert.this).create();
alertDialog.setTitle("Mobilyzer");
msgCountBundle = getIntent().getExtras();
messageCount = msgCountBundle.getInt("Count");
userId = msgCountBundle.getInt("userid");
if (messageCount > 1) {
alertDialog
.setMessage("You have " + messageCount + " New Messages");
} else {
alertDialog.setMessage("You have " + messageCount + " New Message");
}
alertDialog.show();
new Timer().schedule(new task(), 30000);
private class task extends TimerTask
{
public void run()
{
toastHandler.sendEmptyMessage(0);
}
}
private final Handler toastHandler = new Handler() {
public void handleMessage(Message msg) {
if(alertDialog.isShowing())
{
try
{
alertDialog.dismiss();
finish();
Log.i("alertdialog","hide alert dialog");
}
catch(IllegalArgumentException e)
{
Log.e("illegal ","illegal exception in dialog"+e);
}
catch(Exception e)
{
Log.e("illegal ","exception in dialog"+e);
}
}
Log.i("alertdialog","show alert dialog");
}
};
