Thread: Converting Java Code to work with Android

Hello,

I am a beginner with Java in that I have worked through examples from a book. I would like to start programming android applications (simple ones). I know Android Apps use java (I can see the similarities) but words are different to some extent. Would it be effective to convert standard java code (don't know what to call this) to java code used in Android Apps (dont know what to call this)? Or should I start fresh, remember I am just starting out here? In general what changes are there. The first difference I noticed was the package declarations. I just want to know what I am getting into. Thanks in advance.

It is possible to convert some java code directly, but more often than not porting a java program to android will take significant effort, particularly when it comes to i/o and the gui interface. Packages are a part of standard java and android. The biggest differences I can see are the API's available and the execution model. Personally I would recommend getting familiar with java and general programming first before delving too deep into android.
