Google provided documentation for android is very effective for non-android developers who like to learn android but you must have some basic knowledge in core Java.

Java is a pure object oriented programming language that can use for complex application development. Android application can develop in Java or C++ programming language(NDK is required). Java is exceedingly convenient for beginners, Java is considered as a professional language. I strongly recommend Java if you don't use core functionality of android OS. (Some native functionality can be achieved through NDK).

You might be wondering why these prerequisites are important for Android development. Why you can’t jump directly to android Google Documentation?

The answer is very simple most android development tutorials are made up of a Java flavour. If you don’t have enough knowledge in Java you can’t build a perfect android app.

This tutorial unveils, what are the basic concepts you must know before starting with Android development.

It is time to have some fun with Android. XML is a markup language which can able to create UI components for android. You cannot avoid XML when you work with Android.

Many people don’t know how to start android development with documentation. Should I start with HelloWorld ? No, Java core concepts will give you enough confidence to learn android quickly.
