请任何人帮助我......

告诉你。

Answer 1

06-20 13:13:39.839: E/AndroidRuntime(23778): Caused by: java.lang.NullPointerException
06-20 13:13:39.839: E/AndroidRuntime(23778):    at com.globalnest.CaptureActivity.onCreate(CaptureActivity.java:116)

有你的线索。查看CaptureActivity.java的第116行，找出可能意外的null。

Answer 2

你可以假设你的进程被Android操作系统杀死了，如果它在后台工作了半个小时。因此，当您再次启动应用程序时，Android操作系统将重新创建该过程并重新启动仅位于堆栈顶部的活动。

如果堆栈顶部的Activity依赖于其他任何内容（之前可能已设置的其他活动），那么您的应用程序将崩溃。这是因为整个活动堆栈未重新创建。

考虑到这一点，请回顾一下在这种情况下会发生什么。

在恢复时，应用程序在android中一小时后崩溃
