I wrote a 4-screen sketch by adapting the simbleeUItest example app.
It was switching screens fine until some point in my sketch development when it began to crash the
"For Mobile" Android app each time I release a button on the Home screen after having visited the first of my 4 other screens. A crash window pops up, "Unfortunately, For Mobile has stopped" and if I hit the Report option, I can see some cryptic debugging info that suggests it was a crash in processSetVisible on line 3045 (of For Mobile, not my sketch).
I have no idea what is causing this.
How can I debug it?
