In my previous blog, I talked about what characteristics made a good app for Qt in the Android environment. I'll paraphrase an insightful response from Artem Marchenko -- my blog post is really talking only about standalone apps, and not Android integrated ones. That's correct--my blog focused on "easy wins" - areas where you could […]
