Writing a plugin to publish to Android platform

Hi, I am intrested to know about what should I be doing to write a plugin to publish my Unity games to Android platform?? In similar grounds as its happening on IPhone.

Are external developers (i.e. not a developer working with Unity) allowed to write the plugins??

If yes, what would be the next step to go ahead??

Please clarify.

That is not possible.
Games compiled are iphone os games, they run on the iphone os and the iphone os only.
Plugins won’t help on that end in any way as you would have to do something on the build app and you aren’t allowed to as you are not allowed to do any reverse engineering.

You will have to use something other than unity if you want to develop for the android

Currently, Android is coded using a compiled java. It has 2d and 3d libraries already built in as standard and is free. Right now, thats as good as it gets until some 3rd party extensions are released.
I can’t see Unity going to Android anytime soon, especially as there is no money to made making apps for Android yet. Give it a couple of years and maybe it’ll become more commercially attractive to developers.
