So I was having these issues that the android app force closed immediately after connected to the robot on my tablet Nexus 7 2nd gen.
I thought the problem was that I had my tablet upgraded to android 6.0.1 so I downgraded to 5.0.1. Nothing. Even tried 4.4.3 and that didn't work either. (tried both aosp and cm roms).

I read that someone had tried older versions of vortexbot than the one in play store so I went to the github and downloaded the oldest one available version 0.9 and that worked!
For me (or for the nexus 7 2nd gen) is vortexbot 1.1 the last version working. After that it force closes.
I got the apks from here:
https://github.com/DFRobot/DFResources/ ... ForAndroid

Hope I can help someone with this!

The app is now updated on google play and works just as it should!
