Android vs iPhone Development: A Comparison
from - http://java.dzone.comA few months ago I ventured into the world of Mobile development and created an application (Hudson Helper) for both iPhone and Android. This article is about my experiences, comparing Android and iPhone development with a focus on tools, platform and the developer experience.
Before going much further I should note that my comparison is with considerable bias. I’ve spent the past 12+ years in Java development, having spent much of my career building developer tools. Since January of 2004 I’ve been building plug-ins for Eclipse, and before that plug-ins for NetBeans. This bias is somewhat tempered with several years of C and C++ development. With this background I find that I’m very critical of developer tools. Developer productivity is key — anything that takes away from the flow of a developer in the zone is a real problem.
Language, Programming Model and Platform
Language
The language of choice for iPhone development is Objective-C. Objective-C is a language based on C with extensions for object-oriented concepts, such as classes, inheritance, interfaces, messages, dynamic typing, etc. The Java language is used when developing for Android (though it doesn’t actually get compiled to bytecode). Java is a no-brainer. I have to say that it’s nice not to have to learn a new language to target mobile. Existing skillsets don’t come easy — so reuse of expertise is worth a lot.
It took a little while to wrap my head around some of the language features available with Objective-C. I soon discovered that I really loved certain language features, such as message passing (instead of calling methods), categories and named arguments. I did find however that the syntax of Objective-C is cumbersome. I’m still not used to ‘+’ and ‘-’ for static and member methods, too many parentheses are required, and in general I just felt like I had to type way to much to express a simple concept. The IDE didn’t help much with this either (more on that later).
One thing that really became clear to me is that Objective-C, though it may have been visionary for its time, is really a language of the '80s. Certain issues such as split header and implementation files and violation of DRY are really time-wasters, and not small ones at that. I found myself constantly switching back and forth between files, which not only has a cost in navigation (which file to open?) but with every file opened your sense of context must be recreated (where’s the caret, what’s selected, where am I in the file, how is this file organized).
