This is a simple demonstration of the android development process. We use the most common android development platform currently, which is Android Studio. We go through all the processes from creating a project until uploading it to google play store. Android as an operating system is an open-source O.S mostly used for mobile phone development, although it has been used for other devices such as robots, drones, smart televisions, cars, and smartwatches as well. It is what we call “a Linux based operating system”.During the course of this project, I will show different ways of modeling an app, some of which I didn’t utilize in my project but are also very effective ways of design and modeling.We will take a look at android runtime, we will take a look at the libraries, the frameworks, activities, projects, the android manifest, user interfaces, and much more.
