12:47:48 ******************************
12:47:48 You have tried to change the API from what has been previously approved.
12:47:48 
12:47:48 To make these errors go away, you have two choices:
12:47:48    1) You can add "@hide" javadoc comments to the methods, etc. listed in the
12:47:48       errors above.
12:47:48 
12:47:48    2) You can update current.txt by executing the following command:
12:47:48          make update-api
12:47:48 
12:47:48       To submit the revised current.txt to the main Android repository,
12:47:48       you will need approval.
