■ Current conclusion
从日志中看，出现 ANR 的应用非常多（系统应用及三方应用），应该是系统整体资源占用高变慢导致的 ANR。其中 hht_ota_mgr CPU 占用非常高，基本都超过 90%，应该和其他卡顿问题一样。
■ Next action
等其他系统变慢、卡顿问题处理了再分析。

■ 我的分析
---------------------
11-11 03:07:50.830 1565 25375 E ActivityManager: ANR in com.android.settings
11-11 03:07:50.830 1565 25375 E ActivityManager: 91% 2745/hht_ota_mgr: 36% user + 54% kernel
11-11 03:07:50.830 1565 25375 E ActivityManager: 90% TOTAL: 44% user + 39% kernel + 2.8% iowait + 2.6% irq + 1.6% softirq
//CPU使用率也超90%，cpu占用很高 ①
//其中hht_ota_mgr是占用最多的, 且持续时间很长 ②
11-11 03:07:59.368 1565 2721 I am_meminfo: [420007936,310702080,1332023296,796921856,887967744]
//内存剩余300M，总的8G，内存占用很高 ③
//检查了发生anr的trace文件，设定在加载页面，无异常发生，但是由于当前系统拉满了导致处理缓慢，超时5秒发生anr ④
//还出现了其他的anr，发生原因与上述4点一样 ⑤
---------------------
发生anr的原因如上述5点
■ 下一步计划
1.等限制后台任务数量的功能入库
2.hht_ota_mgr待客户分析结果
3.跑monkey时装的应用太多了，包含了很多大型应用，不安装额外应用，只带预置的，基本不会发生ANR的。本身跑monkey就不应该装额外应用, 是否考虑不安装。。

1.安装过多的三方应用，在跑monkey时会产生比较大的影响，大型游戏比较吃资源，应用中也存在各种流氓操作，同时受限于设备的硬件性能，产生的anr问题无法完全杜绝
需要项目上讨论下，测试目标是否合理，目前看，基于上述原因, 无法完全杜绝ANR的发生
先关闭
