Android Studio's debugger not stopping at breakpoints within library modules

Question

At the moment I\'m developing an Android app that is based on third party code. I started to set breakpoints for understanding the code and soon ran into a problem. Suddenly

Answer 1

I had a problem with trying to debug Kotlin code. The debugger wasn't stoping at any of the breakpoints. It turns out it was an issue with Instant run. I removed all the build directories from my project then I uninstalled the app after that I disabled Instant run.

To disable Instant run go to File > Settings > Build, execution, deployment > Instant run > Uncheck Enable Instant Run
