内存/线程相关的方向更改崩溃？

Question

朋友们，

onCreate() 我正在使用异步线程从 web 服务加载数据。 当线程启动时，它会在屏幕上显示进度条并加载数据。

我遇到的一个突然的问题是，当我开始显示活动进度条时，我改变了手机的方向，第二个线程开始 &

应用程序崩溃。（类似的创新目标异常）。

这里是日志猫有没有人指导我这个问题的解决方案是什么？

代码很简单

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.searchbanks);
    threadBank = new AsyncBanks();
    threadBank.execute("","");
}

Answer 1

即使您关闭对话框以便重新创建它，在系统破坏对话框和您将关闭它的生命周期方法之间似乎存在竞争条件。我很少收到关于在配置更改时关闭不存在的对话框的崩溃报告。

我建议在 Dialog.dismiss() 中捕获并忽略异常，以处理竞争条件。这就是我所做的，它解决了我的问题。
