After so many years developing for Desktop and Web, I think it would be great to create something for Mobile as well. Then I started to learn Android last week and my objective now is to develop an App that helps people in some way. I will be sincere and say you that I still don’t know how to create a simple “Hello, World!” in Android (maybe I can learn that in the next days), but I already know how to configure the development environment. So that will be our first step. Let’s go!
1 Download and install Android Studio
To start, we will need an IDE and I have decided by Android Studio for three reasons. First, it’s free. Second, it’s the official IDE for Android development. And third, because I got a lot of errors when I tried to use Eclipse for Android Developers.
2 Download and install SDK tools package
After that you will have Android SDK Manager in your computer.
3 Install Tools, Android APIs and Extras
Open Android SDK Manager and install:
- Tools: Android SDK Tools, Android SDK Platform-tools and Android SDK Build-tools;
- APIs: Android 4.0.3 (API 15), Android 5.1.1 (API 22) and Android 7.0 (API 24);
- Extras: all of them.
In Extras, I think the most important package is Google USB Driver. We will need that to test our projects directly on the phone, what is much better than a virtual machine. About APIs, if you chose API 15, your app will be able to run at least in 95% of devices. Besides that I installed API 22, that is the last one supported by my smartphone, and API 24, that is the most recent Android version.
And now we have a development environment ready to create our first Android project. And we'll do that on next post.
