sounds like your apps were originally designed and implemented platform-agnostic. that is, they were not originally for android because, if they had been, imho, it would not seem so easy as you describe.
take for examples Android Intent, LBS, content provider, AndroidManifests.xml, Services, and other Android-specific components, which are seldomly seen in other mobile platforms, not to mention those android-specific api "constraints". how did you convert those? ----- Original Message ----- From: "Incognito" <[EMAIL PROTECTED]> To: "Android Challenge" <[email protected]> Sent: Monday, April 28, 2008 2:02 PM Subject: [android-challenge] Re: Android/Applets/J2ME >>So, I'd guess if you want an iphone app in its native platform, you're >>going to have a much easier time just manually building it after your >>java version is done, then update it based on diffs. At first glance that sounds like a really good idea. It would probably be true for small apps. i.e. A couple of thousand lines. I have tens of thousands of line of code written (distributted among several applications), easily close to 100,000 lines, and more than 1000 automated unit test cases. Trying to manually convert all this code to objective C would be extremely tedious. I would never have the patience to rewrite code that I already wrote once in a language and that has been tested and debugged thoroughly. Automating this is the best route for me. Then when I want to make changes to my code I make the changes only in Java and then I run the utility to convert the code to Objective-C, thus porting the changes over to Objective-C. >>Even if objective-C has every language feature of Java, and >>is syntactially very similar (or easily transformable), you have all >>the dependent libraries to worry about. Is not as bad as you think. For the IPhone specific functionality, i.e. drawing, touch events, key events, I'm using interfaces that abstract or hide the actual API. So my applications speak to my interfaces and then my interfaces speak to the actual platform APIs. Very similiar to what Java Standard Edition does. So all I have to do is connect my interfaces with the actual hardware or platform specific API's and I'm all set to go.
