Introducing the app idea

Just like the beginning of many new mobile projects, we will start with an idea.
We will create a travel app named TripLog and, like the name suggests, it will be an app that will allow its users to log their travel adventures. Although the app itself will not solve any real-world problems, it will have features that will require us to solve real-world architecture and coding problems. The app will take advantage of several core concepts such as list views, maps, location services, and live data from a RESTful API, and we will apply patterns and best practices throughout this book to implement these concepts.

Defining features

Before we get started, it is important to understand the requirements and features of the TripLog app. We will do this by quickly defining some of the high-level things this app will allow its users to do:

• View existing log entries (online and offline)
• Add new log entries with the following data:
  • Title
  • Location using GPS
  • Date
  • Notes
  • Rating
• Sign into the app
