Testing Android app

Yeah, I've been working on Android app development, but there is one problem. I don't have an Android phone. Previously, I have created several iPhone apps, including my most recent one Codename: Trivia WW2. Anyway, I'm torn between whether or not to buy an Android phone just for programming purposes. Working on the emulator may not be enough. It also seems more challenging from the perspective that the screen sizes are so different. I just hope it doesn't look like crud on certain phones. Apple definitely makes it easier. Oh well, we'll see.
