can we run our android application in all iphone devices?
iPhone uses Objective C, Android uses Java
So Android applications can not be executed on iPhones and vice versa
Just as your Mac can run Windows virtually, iPhone creators have mashed up a solution for the iPhone to run Linux. Porting Android over would be next step as the backbone of Android is Linux (Linux is the lower most layer in Android architecture). But Android OS is the prerequisite...otherwise not....because your Application Package(.apk) cant be installed on any other OS.
Android application cant be used on i-phone as android uses java and i-phone uses objective C.
But if you want to use your application that is built on Android to be used in i-phone, You have to install Android in i-phone. This has been done recently for reference you can see Video in you tube. And for step by step guidance u can use url..
