+******************************
+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.
