How to tell if Flash AS3 is running in desktop or mobile browser

问题

I am developing a full-Flash site (Player 10.2).

I need to know at runtime if code is running on a desktop/mouse computer or a mobile/touch device, so that I can differentiate the input mechanism.

Is this by any means possible?

回答1:

How's flash.system.Capabilities.version look?

回答2:

Use flash.system.Capabilities.os to check.

回答3:

For AIR 3.9: Capabilities.manufacturer returns "Adobe iOS" on ipad2, "Android Linux" on Galaxy s4. Capabilities.version returns "IOS 11,9,900,117" on ipad2 and "AND 11,9,900,117" on Galaxy s4.

You could check to see if the device has accelerometer support. If so, you know it's a mobile device. I dont know exactly what it is you would like to do so I dont know if this will work well for your project. It will distinguish mobile from desktop, though.

if(Accelerometer.isSupported){
    //mobile device
    //os still unknown
else{
    //desktop or laptop
    //os still unknown
}
