In android, there are the use of xml and java. Xml is for the layout design and Java is for the functioning but android has its own libraries. Now, the question is “Is this hard to learn?” Well, there is nothing easy to learn any programming language. We have to give our time and effort to understand the language and takes years to master. But, I found this language pretty easier as compare to other languages.

Now, I am going to share some information about the thing that you need to learn and understand to be the android app developer.

1.      You need to learn the Object oriented programming concept because java is based on OOP. It makes the language and process understandable. Learning oop is the first thing that we need do.

2.      You need to learn some programming language such as java, php etc. I recommend to learn basic java and do some coding and make simple apps. It helps to sharp your oop knowledge.

3.      Now it’s time to learn android application development. You need to download Java JDK and android studio which are fee and can be downloaded easily. Install the android studio in proper guidance. Learning android you must cover following things:
