Hi David,

Welcome to ranch!

I'm basically coming from a java/j2ee background and been in the web development arena for 12 years. What are the fundamental differences between
programming for web versus programming for android? I suppose java is used in the android development world? Is that correct? Memory footprint, hardware considerations etc.

Thanks
Sunderam G

There are similarities in web and android development.
1) file structure is important.
2) XML and java (android APIs) are used.
3) IDE is similar.

There are differences
1) Java is a little different from java SE. However previous java knowledge is a big plus.
2) The devices that run are very different from web servers. Smaller devices yet ever improving in hardware.
3) User experience and UI is very different from web applications.

It takes around 6 months and useful book/books for the average java/java2ee developer to get a good grasp of android.

Hello Sunderam,

And that's a good response Rehan :-)

Yes--there will be a few things that will seem to be very familiar when you start Android development. The AndroidManifest.xml serves a similar purpose to the web deployment descriptor. Layouts are a little like JSPs. Activities are *somewhat* like servlets, but a better analogy would be that they are a little like the backing beans that people used with JavaServer Faces. The truth is, that if you know Java, you will find a lot that is familar in Android development.

Dawn and David
