The SlingPlayer App by Sling Media, Inc. doesn’t seem to connect to my Slingbox when I use the ART runtime. I will retest this when I switch back to the Dalvik runtime.
There seems to be small bug in Lame4Android with Android 4.4 (both Dalvik and ART). The file browser feature doesn’t work. As a work-around, I specified the entire path to each file (/mnt/sdcard/….)
