Core Java Concepts required for Android

Hello everyone,
Nice to meet you

I am new to Java and I want to be an android developer.
I started learning Java Se from Java The Complete Reference.

Till now I completed these concepts

1.OOPS
2.Multi threaded programming
3.Enums
4.Auto Boxing and Auto Unboxing
5.Annotations
6.Generics
7.String Handling.
8. Java.lang
9. Collections Framework

Are these concepts sufficient to start learning Android?
Should I learn any more java concepts?
What are the important concepts of Java for android development.

Please help!

Thank you.

Your list looks fine to me and I think you are reading to join the green army

But keep in mind that you will need to learn Android's specific APIs in order to be able to build applications.
Welcome to the Ranch

Java I/O and networking knowledge will come in handy (for accessing files and network resources). And yeah, there are lots of Android-specific APIs you will need to master. A book like Android in Action can help you get a grip on all those.
