Chernobyl
Crash fast library for Android
Simple precondition library for crashing in case you find unexpected values. For example: After you login against a certain API, you have to get back your user. It's completly necessary to have a no null user, so you can checkNotNull(receivedUser). Antoher example: a user must have an email, so you can checkNotEmpty(user.getEmail()).

checkNotNull(null);
checkNotNull(5);
checkElementIndex(5, 4, "index > size");
checkElementIndex(5, 5, "index == size");
checkElementIndex(4, 5, "index < size");
