Java knowledge for android

The Java programming language is one of the glorious tools that make programming Android a breeze compared with programming for other mobile platforms. Whereas other languages insist that you manage memory, deallocate and allocate bytes, and then shift bits around like a game of dominoes, Java has a little buddy called the Java Virtual Machine (JVM) that helps take care of that for you. The JVM allows you to focus on writing code to solve a business problem by using a clean, understandable programming language
(or to build that next really cool first-person shooter game you’ve been dreaming of) instead of focusing on the plumbing just to get the screens to show up.


You’re expected to understand the basics of the Java programming language before you write your first Android application. If you’re feeling a bit rusty and need a refresher course on Java, you can visit the Java tutorials site at http://java.sun.com/docs/books/tutorial. or you can find some tutorial here - JAVA

Spend time researching and thinking about yourself, the occupation, the organization, and questions you might ask at the end of the interview. Step 1: Know Yourself The first step in preparing for an interview is to do a thorough self-assessment so that you will know what you have to offer an employer. It is very important to develop a complete inventory of skills, experience, and personal attributes that you can use to market yourself to employers at any time during the interview process.
