Want to learn how to develop Android apps? Android is an open-source mobile operating system. It is now the most popular mobile platform. Android now has 1.4 billion 30-day active users globally. And aside from phones and tablets, Android is now in wearables like smartwatches (Android Wear), televisions (Android TV), cars (Android Auto), and IOT devices (Brillo and Weave). There is a lot of potential in the field of Android development.
The best place to learn is of course the official Android developer site, developer.android.com. They have guides, tools, articles, training materials, and other resources there. Read the basics; it will be helpful. The Android Developers YouTube Channel is the home of Android demos, tutorials, and other updates about Android development.
There are also online courses (most of which are free) that you can take to learn about Android app development. Google has partnered with Udacity to develop a Nanodegree Curriculum for Android. Udacity's Nanodegree is both a curriculum and a credential, developed in partnership with leading technology companies. This is $200/month (with 50% refund upon completion).
You can also check the Android courses, which you can access for free. As of now, the Android courses are:
- Android App Development for Beginners
- Developing Android Apps: Android Fundamentals
- Advanced Android App Development
- Google Play Services
- Gradle for Android and Java
- Material Design for Android Developers
- Android Ubiquitous Computing
- Android Performance
The best way to learn Android development though is by doing it hands-on. Try making apps while reading Android materials or taking Android courses. It doesn't have to be publish-ready at first. Experiment and learn from your mistakes.
