On iOS, the embedded web browser or the UIWebView is not identical to the Safari browser. While the differences are minor, they can cause debugging headaches. That’s why it pays off to invest in popular frameworks that have addressed all of the limitations.Building native applications means using the native language of the platform, Objective-C on iOS, and Java on Android. The main advantage of native applications is their performance. Native apps are compiled into machine code (Dalvik byte code under Android), which gives the best performance you can get from the mobile phone.
Best performance includes fast and fluid animations as well as full access to phone hardware, multi touch support and the latest APIs.
Native development is far from easy. Despite the great number of resources that can be found, it may not be understandable to everyone. As code must be written specifically for each platform, the same code will have to largely be rewritten with little able to be shared. The logic may be the same, but the language, APIs and the development process is different. This process can be relatively long for complex applications.
