Hi.. Now that clash of clan is open in android devices, xan they also use itunes card to buy gems in the xlan?

No, the can only be used in the iTunes store (inlcuding in-app purchases on apps), ibookstore and the Mac App Store - they can't be used on Android devices.

If you have an itunes card, you but are playing clash of clans (COC) on an andriod. All you have to do is link you COC account to an apple device by using link a device in the settings menu on COC. (Do male sure that if the apple device owner is currently playimg COC, you must create or enter your Game Center account in the device swttimgs under Game Center, and begin a fresh COC game. Then you can transfer your current COC game safely) Once your COC is on that apple device, simply go to itunes on that device and redeem your code. Purchase your desired gems, and pull back up your COC game on your own andriod device. Gemmmmssss
