I was told by the instructor in my app-development course last Spring to "keep it small and simple," but I'm not sure how much of that was b/c a semester is short.
I'm trying to make an app to teach users how to subtract positive and negative integers. It has six activities and four custom Views for number lines, and my computer gets incredibly slow now. When I deleted an activity (and its related layouts, etc) things ran faster. However, it might be Eclipse that's slow, and not the app.
I could break the app into two apps, but I'm not finding (maybe because I'm not using the right search terms) a way to link to the "next app" when the user is ready.
Since I'd like to make a prequel app with adding positive and negative integers, I need to address this at some point anyway.
