当我的应用程序启动时，发生强制关闭错误

Question

在我的Galaxy Nexus上进行测试时，我通过按下后退按钮退出了应用程序，然后当我再次启动应用程序时，仅在几秒钟后，它导致应用程序转到FC并生成错误报告。任何人都可以帮助我，它只发生在Glaxy Nexus上。 Nexus系列设备是否有限制打开连接？为什么发生这种情况？提前致谢。

Answer 1

这个错误主要是由于这个问题

AppData::create pipe(2) failed: Too many open files

，并能在任何情况下发生的。例如

1. 您在应用程序中创建了很多HTTP connections。
2. 从internal或External SD卡”
3. 或者这可能是一些data access by DB + file writer object和HTTP connections组合开放许多files connection。

解决方案

尽量限制使用像你thread pool网络运放的max 5连接的限制在时间和如果做一些文件操作，那么尝试序列化。对于db close all open connections，每当你退出。

Answer 2

这可能是原因：

[ 12-21 19:43:11.731 2384:14147 E/NativeCrypto ] AppData::create pipe(2) failed: Too many open files 

您的应用程序可能做它用不紧密的资源。
