Java vs Kotlin vs React Native which is the best language for Android development 

( Today we are going to discuss about the three official languages of android here we will discuss about their history, pros, cons and at we will find the conclusion that which is better in all of them )

Java

Java is a official language of Android it is developed by Oracle and the Android OS is also development in Java only, It was released in 1996 in the month of January James Gosling is the developer of Java it was created at Sun microsystems. Now it is mainly use for developing applications and for the Android OS it is very popular for creating appliactions for Android but there are some issues that android developers don't like about it is that it's syntaxs are very long for writing something in the console also it has a very long syntax, it is very slow and it doesn't provide any backup facily also that's why people hate it so much but it is very popular to create amazing, unique and big applications for android devices but why? because it works on oop (Object oriented programming) which helps you to learn other languages easily because all the popular languages works on the concept of OOP, it is very secure, it platform independent, portable, it has a big community so that in future if you face any problem while writing programs and you face any error then there are solutions for that in YouTube, StackOverflow or any other site and stable too that's why people use it for creating applications. But there is also a thing that you can create apps for android only using this applications you cannot use it for creating IOS applications because IOS supports SWIFT only as it's official language. Some of the applications that are created using Java are - Netflix, Spotify, Amazon, LinkedIn and more.

Kotlin

Kotlin is also a official language of Android as like Java. It was releases in February 2016 which is a bit new compared to other officail languages of Android like Java or React Native it was developed by Google it has a very easy to learn syntax and as it is bit new you can create also create big apps using this language  some of the popular applications that are created in Kotlin are Pinterest, Evernote, Coursera, Uber etc and it is also a very good language to learn as it is very easy to learn, it increases the team's productivity as you have to write less code compared to JAVA, it less buggy, compatible with your existing Java Code and it's easy maintainable and more features are there for Kotlin but as advantages languages also has some disadvantages like it is a new language so it has a small community compared to Java means if you face any error in code then there are less chances that you will find it's solution in stackoverflow or any other site but as it created by Google may you find it's solutions that their documentation, it compiles the code bit slow etc.

React Native 

As like Java and Kotlin react native also a official framework of Android it was developed in 2013 by Facebook and it was released in 2015 (1 year before the release of Kotlin) in the month of January and as of now many developers are also using this for creating applications some of the popular sites that are created using this framework are Discord, Facebook, UberEats, Instagram, AirBnB and more sites are there that are created using React Native as you have seen that so many big sites are created using this framework so if you are a good developer then you can also create a big site using React Native. Some of it's features are that will help you create such big applications are it has a common code base, it takes shorter time to market, it is very easy to learn and code, it is a open source framework and some of its disadvantages are that all apis are not supported for React Native, it has less third party libraries etc. But also a good thing for this framework is that it has a mature community so that if they create or find solutions for their problems then they share that solutions in stackoverflow or any other site. 

Conclusion: According to me if you want a language that provides you features to create very big applications then Java is good or if you are Java developer then you should choose Java only as you are already an experience person in that language and if you want to create a bit big language or if you are not a beginner you are experienced android developer then you can choose any of Kotlin or React Native both of them are good but for JavaScript developers and web developers I will recommend React Native only as it has a bit similar syntax like React JS. Both of them use JS. 

But if I declare some language or a framework as a winner then I will choose React Native as it is growing community in Android development and for web developers it is a perfect framework to learn as they have learned JS already in their web development carrier and it also has a good community.
