1.买了一个nexus 6, 编译了源码aosp_shamu_userdebug 版, 刷机器为aosp编译出来的rom, 然后修改SystemUI里的东西(只是加了一些log, 为了查看流程), 然后adb push 到手机, 就出现了systemUI异常的问题. 然后把原来编译出来的SystemUI(未做修改)adb push到手机, 依然出现systemUI异常的错误.

1. 采用的是aosp的源码, 直接在github上可以搜到.github源码地方:https://github.com/android/platform_frameworks_base/tree/master/packages/SystemUI

3.一下出现的错误信息

4.报错是systemUI发生异常, 然后是不断的重启SystemUI, 不断地发生异常.
5.目前在so上发现一个类似的, 但不全像我的问题. 连接在此:http://stackoverflow.com/questions/32115650/android-app-crashes-when-trying-to-read-contacts-in-android-marshmallow-android
