How well do you need to know Java to create an Android application?

Question

Java

Good day.
Interested in creating a social network application. As far as I know, applications work through the API of a pre-designed back-end. Essentially, apps are conduits. Therefore, I had the following question: how deep do you need to know Java in order to create a full-fledged social network application that works on the basis of API interaction of a pre-developed web application (server)? Having skimmed over the lessons from Android, I can assume that knowledge can be superficial, since all the necessary functionality (uploading photos to the server, registering, etc.) already has its own, created and tested third-party libraries. Take and use. Or I'm wrong? Thanks for the replies.

Answer 1

At the very beginning, knowledge can be almost zero, now it is increasingly practiced to study both android api and java at the same time. But you need to understand that it will be necessary to gain knowledge. Creating an application based on ready-made api and libraries is also not an easy task.

about 19

Answer 3

From my own experience. I started Android without any knowledge in java. As a result, many questions arose as to why it is so, and not otherwise. Usually, such questions are not answered in Android books / courses. Switched to java for a while - it helped. It will be enough to take any book on java and go through it at least superficially in order to have at least a general understanding of what is in the language and how it is accepted. Since if you have to write something more serious than 'Hello world' - problems may arise.

Answer 4

according to your tasks.
For a primitive application with one button and the helloworld level is enough.
