I am trying to learn the fundamentals of Android. I am currently in the process of creating a calculator application (nothing too strenuous). So far I have designed it through PhotoShop (based around FlatUI colour schemes) and I've coded the UI for portrait mobile. I want to have a separate layout once the device's orientation is changed so it transforms into a scientific calc. I also need to design two layouts for Tablet.
It's nothing really exciting but it will help me to learn more about the SDK, IDE (Android Studio) and the phase of designing, implementing, testing and releasing an application.
