可以看出system_server进程占用了cpu的大部分时间，而且存在多个线程池在syste_server中作业。
结合测试操作流程，从逻辑层面来看，因为应用宝使用系统的辅助功能，会在安装apk时，实现自动点击，自动安装的一些列操作，而这些操作都会
与system_server有交互，大部分操作是在system_server进程中完成，而且安装的应用又很多，会长时间的在system_server中通过packageinstaller进行作业，
在packageinstaller发生的输入事件会因为当前系统卡顿导致响应延时，发生ANR。

系统卡顿从下面的日志也可以看出，系统不停的在做GC，说明当前的内存使用告急，应用宝又不停的在下载安装应用，导致系统的整体性能出现瓶颈

2、综合来看

anr的发生是因为在应用宝中下载了很多的应用，进行静默安装，使用系统的辅助功能完成该流程，而这一系列的操作都会涉及与system_server交互，特别是安装的逻辑
都是com.android.packageinstaller通过system_server完成，不停的下载以及不停的安装，导致系统整体性能下载，cpu使用过载，内存使用告急，这个时候
com.android.packageinstaller中发生了输入事件，就有很大概率发生处理超时，发生anr。

3、处理策略
下载安装apk的这个操作，如果系统当时的整体性能正常，cpu负载不高，内存使用正常，一般是不会发生anr的。
但是如果下载大量的应用，并且使用辅助功能进行安装操作，这种操作本身就会加速cpu和内存的使用，会降低当前系统的整体性能，如果这种操作反复执行
或者当前系统已经存在降低的情况，那么发生anr的概率就会加大，而这种操作引发系统整体的性能降低发生anr，是没办法从系统层面进行处理的，
只能建议不要一次性下载安装太多的应用，分批次来完成该操作，将系统性能的整体消耗进行分散。

综述：该票不做特殊处理，维持现状。

需要确认下发生的场景，如果存储空间剩的较多，且仅同时安装几个应用时，就会发生的话，很难推不解

[下一步动作]
确认复现的条件

【】信息确认

从目前与测试的沟通和问题的调查情况来看，
该问题的发生的必要条件是：
1）在应用宝中一次下载20+的应用；
2）开启应用宝中的“自动安装模式”；
而当前存储空间的大小与问题发生不是必要条件，只是在存储更小时，问题发生的概率会大一些

@测试同事
请帮忙明确下面几个信息：
1）该问题的发生概率是多少？比如在存储很多正常的情况下，发生的概率（？/10）;存储不是很多的时候，发生的概率（?/10）;
2）是否可以使用不同类型的应用市场软件进行对比测试，看是否发生该问题，如果发生请记录日志和anr等信息？比如：华为市场、小米市场等；
