Your Way to Android

▪ Building native applications means using the native language of the platform such as Java on Android.

▪ The main advantage of native applications is their performance .

▪ Best performance includes fast and fluid animations as well as full access to phone hardware, multi touch support and the latest APIs.

▪ Hybrid applications are web applications (or web pages) in the native browser, such as WebView in Android.

▪ Hybrid apps are developed using HTML, CSS and Javascript, and then wrapped in a native application using platforms like Cordova.
