Xml is very important to write android apps or i can use only java to develope androud apps?

Answer 1

XML is like the CSS of java, it just makes Java GUIs easier to design but you can just use java code instead of XML, I find it easier jut using java as XML requires new file and extra code to locate the file

Answer 2

to me, XML is important for developing your app, it makes the designing part easier...
