AIDE is an integrated development environments that lets you develop Android apps... from an Android app. Now the piece of software has reached version 2.5 and is taking things a step further. Instead of merely letting you code, it's prepared to teach you how. The latest version provides interactive lessons with step-by-step instructions, so you can learn how to program in Java and develop for Android at your own pace.

A couple introductory lessons are free, but the rest require an AIDE Prime subscription that comes in the form of a recurring in-app purchase. You can pay $4.99 a month or save yourself 50% by coughing up $29.90 annually instead.

There's a premium key in the Play Store for $9.99, but it doesn't provide you with any of the paid lessons. You get the following features instead.

What comes with the AIDE Premium Key:

  • Saving files in pure Java projects
  • Saving files in larger Android projects (5+ Java files)
  • Direct run without user prompt on rooted devices
  • Git push/commit
  • APK publishing
  • Offline SDK Help
  • Some customization options
