Attaching a debugger sometimes causes the app to crash

Question

I'm developing an Android application, and sometimes when attaching a debugger to the running app, after a while it causes it to crash. The stacktrace is below. I should mention that I'm running the N preview in the phone.

Answer 1

So I was able to fix this on my project. I read here that it had something to do with breakpoints set on nested functions. For me to solve this issue, I had to go and view all my breakpoints (Shift + Command + F8), and remove all of the breakpoints I had set. I had a few disabled breakpoints, and I didn't bother to look and see where exactly the breakpoints where, but I removed all breakpoints (both enabled and disabled) and it fixed this problem. I don't know if this has anything to do with breakpoints on nested function. Others have said that by turning off instant run it solved the problem.

Hope this helps someone else!
