This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The book examples run on the Android emulator and the T-Mobile G1. In principle, they should run on most, if not all, Android devices as they come out. In practice, they will only be tested on the emulator and a couple of models.
