The Blog Reader app will teach us one of the most common and important uses of an Android app: downloading data from the Internet and displaying it in a list. We will investigate the Model-View-Controller design pattern that is essential for all Android apps, learn how to request data from the web, parse and use information in JSON format, and utilize the built-in Android ListActivity and adapter. We'll also see how to display a webpage inside our app.
Using the right tools can make an Android developer's life so much easier. At Google I/O in 2013, a new Android IDE was announced named Android Studio. Currently available as a beta release, we will see how to get started and learn some helpful features that make it powerful and fun to use. Then we will take a look at a 3rd party emulator called Genymotion that is much faster and more responsive than the default Android emulator. And lastly, every developer should be using some sort of version control, even on small projects. We will show you how to set up and make changes to an Android project on GitHub.
In the Self-Destructing Message app we will build on the concepts learned in previous Android projects to create an app that will allow users to send photo or video messages to other users that will be deleted once viewed. The app will be tab-based, meaning we will cover Fragments, and we'll dive further into layouts, list views, and the Activity lifecycle. The backend of the app will be built on Parse.com's popular cloud storage services, which will handle user accounts and file and message storage.
In this project we will see how to implement a clean and refreshing flat design for the Ribbit app from Build a Self-Destructing Message Android App. We will start out by implementing custom login and sign up screens, and then we will heavily customize the ListViews and the rest of the app, including using a custom theme and styles. Finally we'll add a few improvements to the app like pull-to-refresh in the Inbox and getting Gravatar images for users.
