I think it is time Nokia jumps on the Android bandwagon. Java is a very common tool used for developing mobile applications that is why it is used. Besides while Android does have its limitations it is more open the Symbian, iOs, Windows Phone 7, and Bada os. Besides just because Android isn't full Linux doesn't mean it isn't open. Linux isn't the be all end all of openness. What has crippled Android isn't programing (80,000 apps in Android appstore) but rather manufacturers and carriers imposing restrictions trying to make the platform closed and trying prevent people from uninstalling manufacturer skins and carrier crapware. Also rooting become harder example Motorola Droid x has a locked bootloader and Samsung Captivate prevents sideloading of nonmarket Android apps. So What Google would need to do is try to stop carriers and manufacturers from crippling the platform but that would be almost impossible.
