无法解析API文件"frameworks/base/api/current.txt"

Question

我尝试在Android框架中添加一些文件.一切顺利,除了在编译结束时,我遇到了错误.

我也试过make update-api,但没有运气,每次编译它都会给出以下错误.如果有人知道如何解决这个问题,请告诉我.

******************************
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.txt by executing the following command:
         make update-api

      To submit the revised current.txt to the main Android repository,
      you will need approval.

Answer 1

这个问题的原因是,

原因: - 我在Android框架中添加了私有类,必须添加这些类文档/声明“frameworks/base/api/current.txt”

解决方案: - 根据错误日志,有两种解决方案.

1)在每个新添加的文件及其成员中添加@hide注释method's Signature.

2)$ make update-api然后 使用命令$ make -j4或者使用命令$make update-api && make -j4,现在代码应该是可编译的.
