I wish I had an answer for you. I have seen coding with tabs using Intents to be very flakey. It will work, then not work. I'll restart the emulator and then it will work again. Very frustrating. I think there is a bug somewhere in Android, but I can't prove it. Did you ever get you issue worked out?
