I once led a project that had an android app years ago. Someone on the team brought in guava for a small number of helper utilities. This made our apk exceed the method limit which required some partitioning (forget the details) that increased the time to push the app from like 15 seconds (which was still way too long) to a minute (which I found unbearable). One day I ripped out guava, handwrote the parts we were using and got our apk size safely within the method count limit. The project still failed horribly though but for other reasons :)
