There are two default development tools you can use for native Android development. The de facto tool is Google’s Android Studio. Android Studio was introduced in 2014, but don’t let its newness fool you. It is a good tool designed specifically for mobile development. Google has put a lot of thought into Android Studio and you will see cues Google has taken from leading development environments such as Apple’s XCode and Microsoft’s Visual Studio. The other tool you can use for native Android development is the open source Eclipse Studio. Android Developer Tools (ADT) for Eclipse is a plug-in you will need to download. It should be noted that Google does plan to retire ADT in favor of Android Studio.
