Can android apps written in java run on iOS?

[sweettooth_15]

I'm still new to android development but if I were to develop an app in Android, can it also run in iOS if it's written in Java?

If it is a compiled application it will not run on anything other than the target hardware. That is because the code is changed to the binary or machine language values that perform the appropriate operations. Two dissimilar processors do not interpret the binary codes in the same way so they won't work.

Also, compiled applications usually make calls to the operating system. Again, if the OS is not the same then system calls may be trying to address a function that does not exist in that OS.
