CREATING AN APPLICATION FOR ANDROID PHONES
You need to learn basic and advanced Java programming first before you can create a standard application used on the Android operating system. The primary software used for the development of Android applications is a little program named Eclipse.
This program is used for other programming languages as well, but Android programming is one of its recommended use. If you want to study Android programming in an easy-to-understand, step-by-step tutorial, you can go to The New Boston’s website Android and its Android Development section.
This is a pretty great tutorial website because it is presented in video form. The tutorial is divided into properly titled sections that are very beneficial to your Android development learning. Everything is covered from installation of Android components and the Eclipse software, to placing your application to the Android Market (now known as Google Play).
This is a great tutorial trust me, because I learned greatly from this.
Hope this helps!
