我正在尝试修改AOSP（主分支）中的指纹trinturecontroller api，以返回布尔值，而不是void，但即使在重新编译SDK之后，我也会继续错误地构建项目。
。错误是：

******************************
You have tried to change the API from what has been previously released in
an SDK. Please fix the errors listed above.
******************************
我遵循的编译的步骤是：
lunch sdk-eng
make update-api //Success
make sdk //Success
lunch 1
make -j10 //Errors out here
有人可以指导我如何在源代码中更改Android发布的SDK API并编译Android。
您需要确保随着方法签名更改已更新以下文件：
/frameworks/base/api/current.txt
/frameworks/base/api/system-current.txt
/frameworks/base/api/test-current.txt
只有一个提示：您是否实际修改了api/26.txt文件，以反映您的API更改，然后再进行make update-api？
