Found a small bug in devrant:
If you double tab on an already ++'ed rant it opens twice so if you have to press the back button two times to get back to the rants list.

It's a known bug.

This made me realise I've the bug in an app I made as well. I'm guessing the on click listener is still active while the other activity is launched so the double tap gets registered as two seperate clicks launching two activities. I guess making the activity singletop could solve this but I guess there could be some downsides to that.
