For the next three years, Google must meet the following criteria:

• Allow third-party app stores for Android, and let those app stores distribute all the same apps as are available in Google Play (app developers can opt out of this);
• Distribute third-party app stores as apps, so users can switch app stores by downloading a new one from Google Play, in just the same way as they'd install any app;
• Allow apps to use any payment processor, not just Google's 30 percent money-printing machine;
• Permit app vendors to tell users about other ways to pay for the things they buy in-app;
• Permit app vendors to set their own prices.

Google is also prohibited from using its cash to fence out rivals, for example, by:

• Offering incentives to app vendors to launch first on Google Play, or to be exclusive to Google Play;
• Offering incentives to app vendors to avoid rival app stores;
• Offering incentives to hardware makers to pre-install Google Play;
• Offering incentives to hardware makers not to install rival app stores.
