Art isn't about what you have, or what you use, art can be made from the simplest materials. Art is about invention, imagination, individuality . . . you don't need expensive tools and materials in order to be creative.

A friend of mine has an Android app that’s been working great for over a year but started erroring last week.
Different Android versions, different hardware platforms, all showing errors over the last few days.
Any other Android devs seeing this?
Any clues? Thanks!
