Foreword:

Android is developed using the java language. I believe that almost all of the beginners of Android mobile development have been exposed to java. Therefore, the JDK installation and configuration should have been configured. I will not repeat them here. The following mainly introduces the recording of the installation and construction steps of Android Studio:

Install Android SDK

Android SDK is a free and professional programming language used to create Android applications. The Android SDK developed by Google for its Android platform is a convenient program for mobile application developers.
Android Studio is an Android development environment based on IntelliJ IDEA. Similar to Eclipse ADT, Android Studio provides integrated Android development tools for Development and debugging.

It doesn’t matter if you don’t have the SDK installed on your computer, because Android Studio will download the SDK itself. Here you can also download the SDK yourself, and unzip the downloaded zip package to a medium disk directory named by the English specification. Later, the Android Studio configuration points to the SDK. Can be
