Answer 1

Problem occurs for me with projects which use Support library.

This thread helped me a lot to resolve ClassNotFoundException issue with ADT 22:

https://code.google.com/p/android/issues/detail?id=55304

The idea is to enable Android Private Libraries on Java Buils Path | Order and Export

Nikolay's workaround works for me: For all projects (app and library):

1. Right click the project, and choose Properties
2. Go to Java Build Path-Order and Export.
3. Tick 'Android Private Libraries'
4. (Optional) Clean all projects if necessary

Thanks, Nikolay.

After the mentioned steps,it required eclipse restart for me to get rid of this issue – Messuage

Do this on all the library projects as well. – Feer
