Learning Android™ Application Programming will help you master modern Android programming by building a fully functional app from the ground up. Working with the Android 4.3 toolset, you’ll solve real-world problems faced by every Android developer and learn best practices for success with any mobile development project.
Ideal for developers who have little or no Android experience but have basic Java experience, this tutorial teaches through carefully structured exercises that address the entire development process. Leading Android developers James Talbot and Justin McLean guide you through building a real biking mobile app that can handle everything from mileage tracking to route planning. Each chapter builds your knowledge, step-by-step, and in the end you will have a complete, working app.
Along the way, you’ll gain hands-on experience with writing code that can run on the widest spectrum of devices while still leveraging Android’s newest features. You’ll also discover proven solutions for the occasionally messy realities of Android development, from inaccurate sensor data to inadequate device battery life–pitfalls that most other Android books ignore.
