Android在OnActivityResult中不显示对话框

现在我发现在其他机器(不是我的机器)上会抛出错误：

MainActivity has leaked window that was originally added here

我觉得onCreate()方法中的代码有时会取消对话框？尽管仅启动UI内容和一些后端通信

更新：在另一个设备上运行该应用程序时,致命信号11(SIGSEGV),代码1,在tID 12737(RenderThread)中的故障地址0x24(更快,用SGS6代替SGS $).对话框出现,单击imagevIEws之一时出现此错误

解决方法:

尝试在需要显示对话框的OnActivityResult中设置一个标志,然后在onResume中检查该标志,然后在此处而不是在OnActivityResult中创建对话框.
