Heh, this is cute.
Let me lay this out for you. IF (big if, considering the judges already outspoken distaste for the trial, and the general consensus among most analysts, legal, and technorati that niether side has a very strong case) Oracle beats Google, Google will simply pay a fine and probably license fees. I dont know if you checked, but Google makes a lot of money across a lot of platforms - and I'm talking profit, not operating revenue. given it's current momentum they could easily offset these costs with licensing fees of their own (which would suck, as this means prices go up, but you're already paying premiums for other devices as well).
Android wont die. Even in the worst case scenario, It'll be 3 years before Microsoft gets anywhere close to Android or iOS marketshare simply due to turnover and life expectancies of products even if Android suddenly becomes illegal to produce and sell.
That's not to say anything bad about windows phone. It's an excellent product, and even though everyone hates on the ecosystem it's actually really good. 70,000 apps. Think about that for a second. "Well thats small compared to-" No. It's at least 700 times more than you're ever likely to use, and at this point Microsoft actually has one of the best Quality:Quantity ratios because they're paying "upper tier" developers to come over to their side, and that's only accelerating. They'll make a big deal out of Apollo or whatever they're calling the next big version (wouldn't be surprised if it's Windows Phone 8 time with the Windows 8 launch considering how big of a stiffy Balmer has for the whole unification thing) because the whole point from their perspective is to upgrade the Kernel for Windows CE (which is old old old and apparently crap) to a newer kernel, but it's not yet confirmed if it's the same or at least spiritual relative of the Windows 8 NT kernel. Time will tell. I'm rambling.
Windows 8 has it's pros and cons. But it's got a long way to go and stiff competition, and this Oracle vs Google thing - regardless of outcome - will not give windows a competitive advantage. They have to make their own, and they're on the right track, but so are Google and Apple in their own way.
