Android training - Java related common queries

We have been teaching Android course in Chennai as well as conducting online android training for a while now. These are some of the common queries that we get regarding Java –

1) Why does Android use Java instead of some native program?

- For various reasons, actually.
Unlike native programs, Android runs on many different hardware platforms. You would need to compile and optimize your native code for each of these different platforms to see any real benefits.
There is a large pool of developers already experts in Java.
Java is open source with good support, many libraries and tools available to make developers life easier.
Java doesn’t have problems inherent in native code, like memory leaks, bad pointer usage, etc.
Java allows you to create sandbox apps, and create a better security model so that one bad App can't take down your entire OS.
2) Is Java knowledge necessary for Android?

Java is not compulsory, but preferable. You can use frameworks such as phonegap, which allows you to write code in HTML, CSS & Javascript & it can be used to make Android apps. But even for this, you need a little Java knowledge to make the app work. There are quite a few other alternatives too.
But java is the standard way of writing android apps & there is no necessity for you to avoid it.
3) How much Java should I know before learning Android app development?

The basic knowledge would be sufficient, especially these -

Declarations and Access Control
Object Orientation
Assignments
Operators
Flow Control, Exceptions, and Assertions
Strings, I/O, Formatting, and Parsing
Generics and Collections
InnerClasses
Threads
4) Can I join Android course directly without knowing Java?

We cannot talk for others, but you can join our Android training program directly without any knowledge of Java because our Android course curriculum covers Java too. At Web D School, the syllabus of Android course is most comprehensive, as we actually start from the fundamentals. So, if you are looking for a best training institute to learn Android course, welcome to Web D School!
