Wait till you see the Kotlin stuff (and the Android documentation)!

The very basic and first-must-know part of Android development is getting to know the UI components. This app does the same thing by making you acquainted with the structural components of Android from the Get Acquainted section of the app, which makes easy for beginners to understand and identify the building blocks of Android.
Further, to guide you more, there's the official offline documentation, for learning both, Android (https://developer.android.com!) and Kotlin (https:/kotlinlang.org).
You can turn on the internet for additional styling in the documentation if you want.
Implementation of different libraries will be added, and even the newly added Android components will be added in the future updates.
You can push yourself by taking a quick quiz, wherein the answers to the questions will be displayed with an explanation for the same.
Learning Android was never so much easier! All you need to do is download the app and get going.
You will also get a daily dose of a quick tip whenever you visit the Tip of the day section!
The "Learn Kotlin" section is filled with the complete documentation and easy to use search box for the content you're looking for. For those who do not know what Kotlin is, it is the latest programming language developed by JetBrains, which is interoperable with Java and is really simple to learn. Again, learning Kotlin and specifically learning Android was never so much fun!
