Question

Errors occurred during the build.

Answer 2

Eclipse platform version=4.2.0. Android SDK 4.3 and 4.2.2 both I used. Nothing worked for me in the web. Tried to update the eclipse and many more setting changes as suggested in forums.

Eventually I use a fresh eclipse. That was the only way.

Answer 3

In my case simillar error was produce by eclipse, when in class i write only

import

this result in invalid compilation in file below problematic one.
