  3. Install the latest version of JDK or Open JDK
  4. Install the latest version of Android Studio (at the time of writing this book, the latest version is 2.2.3 and any newer version should be fine)

Installing Android Studio

Visit https://developer.android.com/studio/index.html to download the latest version of Android Studio. Google highly recommends using Android Studio for all Android application development, since Android Studio has tight with and useful Android APIs:

After the Android Studio installation, it's now time to download the necessary SDK in the SDK Platforms tab in SDK Manager. Install one complete version of Android; for the scope of this book, we will install Android 7.1.1 API level 25:

But updates from this channel are not recommended for application production.

Dev Channel: On this channel, a happens after a complete round of internal testing from the Android Studio team.
