I am writing because I have not found many explanations online using the program. For example, all items “property” of each item that will fit on the screen, many are truly incomprehensible to me. Then, in the Test Center, what is the “web security” is not clear. I think the biggest problem, aside from the numerous crashes reported to me, is the rotation of the screen: the application does not conform created and remains unmanageable content. Is there a way to overcome it? I created my first application but I had to create it only in portrait, otherwise it happened that in landescape the contents were not managed well. I need help: I want to make an application that intercepts my location and calculated the distance from me and I find, for example, a store that is far from me. What to do? I’m not a programmer, you have something ready? Thank you, we look forward to the next version hoping that in addition to not go in crash, there is good news. thanks
