Sorry guys, there was a function that I thought was introduced in 4.0, and apparently it was introduced in 4.1.... long story short, if you're running Android 4.0.x then Auto Respond 1.2.7 may crash on opening. (Android 2.x should be fine, 4.1.x and 4.2.x should also be fine)
188.8.131.52 fixes this, I accurately changed the cutoff for that function's usage from 4.0 to 4.1.
184.108.40.206 was JUST published, so it may be a while before it is live. If you haven't updated to 1.2.7 yet, you may want to wait until 220.127.116.11 is live on Google's servers. Sorry for the mixup :-\
