I will be publishing my app in couple of weeks but before that, I need to know something which I think might me important. To my knowledge the only way to publish the .apk file of my app is through Google Play. Am I right? If wrong please correct me. What else do I need in order to publish my app? Is there anything about license or something more important that I should keep in my mind?
Second thing I need to know is about update. After I have published my app at the Play, what if I need to release an update? To provide an update in future do I need to add something in my code or something in the manifest now at this moment of my development process? What are the important points should I keep in mind now so that I could provide an update later.
