At work I have pretty poor internet connection on my phone. Because of this, sometimes when I try to use the Android app it fails to connect. Instead of this being handled nicely, the Android Stack Exchange application displays a black screen for a few seconds then crashes completely.
Not sure if this is a versions specificversion-specific bug, but I'm experiencing this on Android 4.4.4 with CyanogenMod 11.0-XNPH44S.
