Is WWW class usable in Android platform?

This seems like a trivial question but if yes, then why is it that when I use Unity Editor to play a scene containing scripts that uses WWW class and the editor automatically switch the player to Webplayer platform without any notification? Or is this a bug in Unity Editor?

Now I have to switch back to Android platform and waste another 3 hours re-importing all assets included in the project. I really wish there is a good explanation for all the time wasted.

Your should do like this in your editor’s class :

BuildPipeline.BuildAssetBundle(Selection.activeObject,
selection, path,
BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets,
BuildTarget.Android);//Look here
