在我的应用程序中，我使用线程来显示启动画面。 。 。 但我也已将Android许可授予我的应用程序。哪个也使用线程。 。 。 但是，当我安装应用程序时，它运行一次.. 如果我再次打开它然后它崩溃了。问题出在哪儿 ？？？ 代码如下：

我认为线程中可能存在问题。 。 。请帮我解决一下。 。谢谢 请帮帮我。 。 。 让我告诉我，虽然我能够立即运行该应用程序。 。 。 提前谢谢。
答案 0 :(得分：1)
你能试试splashHandler.postDelayed(new Runnable(), DURATION); ?
并将其添加到字段private Handler splashHandler = new Handler();
