title: Porting processor-intensive app to Android - limit devices?
body: <p>I have a rather processor-intensive app that I'll be releasing shortly for iOS.  The iPhone 3GS, 4, and iPad hardware can handle the app fine, but earlier iPhones and early-generation iPod touches don't perform well enough to execute the app.  In the Apple App Store, I'll be able to limit the devices the app can be installed on my requiring the devices to be armv7 -- that way, I won't have to worry about disappointed users with earlier devices complaining because they installed it and it doesn't perform well or correctly.</p>
  
  <p>My question:  If I were to go through the effort of writing the app for Android, do the marketplaces (or the apps themselves?) have a similar way of requiring a certain amount of performance ability?  I'd like to avoid having an app out there performing badly on older devices that weren't meant to be able to handle it anyway.</p>
