If you head over to Facebook Engineering's latest note, you'll find a lot of words that generally don't in any way forgive the fact that Facebook's official Android app is nothing short of an abomination. You will, however, find instructions on how to join the beta testing program for that app buried in this manifesto, near the bottom. Here are those instructions.
- Join the Facebook for Android Beta Testers Google group
- Allow beta downloads by clicking Become a Tester in the Play Store (you need to join the Google Group before becoming a tester)
- Download Facebook from the Play Store to update your app
- Join the Facebook for Android Beta Testers group on Facebook to tell us what you think
Now, there might be a slight delay between steps one and two (the Play Store link may 404 for a few minutes before it recognizes you), so be patient.
