Android is an operating system based on modified Linux kernel. It was designed primarily for touchscreen mobile devices such as smart phones and tablet computers but now this coming in TV, Wear. Auto and other systems also. Initially developed by Android, Inc., Google later bought in 2005.

Google announced Kotlin as an official language so I will convert each post to Kotlin with Android, now Java is old with Android. Kotlin comes with lots of features like reduces boilerplate code, provides null safety, 100% interoperable with Java and Android, supports higher functions, supports lambda expression, supports string template and many things as Kolin comes from industry not academia.

I have provided many examples here so before starting, download android studio from Android developer site. I will convert all posts with Kotlin programming as soon as possible. Keep updated with our YouTube channel as well as I published many videos there and will publish more videos according to update.

I have created Master in Android app which contains Android tutorials and tools to help all Android developers. Best things in app is that you can "Run Kotlin or Convert Java to Kotlin code".
