Strange error appears from time to time in my builds. In my case most of
the times are:
1. Forgot to add an activity to the Manifest
2. A missing uses-permitions on the Manifest
3. Needed to rebuild the project (manually remove gen and bin directories)
+ Project Clean (sometimes the clean does not removes files correctly)
Also as other mention read in the detail the error message.
