Question

I am going to develop an application which will be cross platform and it will be released for IOS and Android.

My App will be using network connectivity and communicate with the server and it has to be fast, reliable and responsive.

So my Question is: If i choose Adobe Flex to build that app for IOS and Android, So will there be any performance issues?

If no then why people use xcode or android sdk?
What are the disadvantages of using Adobe Flex over xCode and Andoid SDK?

Generally speaking, if you use a cross-platform “write it once and build for many platforms” tool you likely will give up the ability to take advantage of some (or all?) device- or platform-specific features. You are, in effect, choosing a lowest common denominator sort of solution. That is to say, you have available to you only the platform features available on ALL the platforms you are targeting.

Building a native app — that is, using Xcode to build an iOS app and using the Android SDK to build an Android app — gives you complete access to all of a given platform’s specific features and capabilities, thereby ensuring the best user experience on each platform.

This is now my opinion: Native apps are better, simply because they present the user with a native experience — an experience that will feel familiar to them as a user of the platform. When you choose to use a cross-platform tool you are actively choosing to give your user a less-than-ideal experience on their device, but YOU saved some time (maybe) getting your app to market. Who’s the winner?

In my job, my boss and I had a specific conversation about this. We have native iOS and Android apps, on purpose, because we didn’t want to give up platform-specific features. We wanted each app to give the best experience it could on its platform. We specifically agreed that a cross-platform solution was not the way we wanted to go.
