需要修改frameworks/base/下的代码，请注意 ：如果修改了Android原有API的 ，需要update frameworks/base/api/current.txt。否则编译被中断并出现下面提示。
可以通过运行 make update-api 后，自动更新此文件，检查确认正确后，跟代码一起提交即可。
Note: 本周碰到这样case ，是因为修改了： M frameworks/base/core/java/android/provider/Contacts.java
Install: out/host/linux-x86/bin/apicheck
Checking API: checkapi-last
Checking API: checkapi-current
*******************************************************************************
You have tried to change the API from what has been previously approved.
To make these errors go away, you have two choices:
1) You can add "@hide" javadoc comments to the methods, etc. listed in the
errors above.
2) You can update current.xml by executing the following commands:
p4 edit frameworks/base/api/current.xml
make update-api
To check in the revised current.xml, you will need OWNERS approval.
