Cannot debug, Fatal signal 6 (SIGABRT) at 0x00007c37 (code=-6)

Question

I ran into the following situation where I cannot debug the android app. I can run it but cannot debug it. I started brand new project copied everything and it worked (meaning was able to debug) but got this again. I tried both on emulator and my phone but no avail. I am using Android Studio 0.5.1

it fails at the very beginning. i don't feel like it has entered MainActivity. The moment app launches, I get "Unfortunately btbnie has stopped working" message.

Appreciate any help/direction...

Answer 1

I got the same thing: ClassLoader error followed by SIGABRT, but only when running the debugger.

For me, switching from ART to Dalvik fixed it.
