Nothing too exotic. I have classes in a library project, which is set to “Is Library”.
The target application project uses this library under the Project Properties/Android section. The project is set to version 2.1-Update (api 7).
None of the classes from the library are visible in the target project. i.e. import statements referencing the classes are underlined in red.
Any ideas?
Try restarting eclipse also try selecting and applying different API level for the project, then apply, then change API level back. I sometimes seen such a problem, usually these actions help.
