Google envisions bigger and brighter things for the future of its Android platform. We recently saw how 850,000 Android devices are being activated every day, but that’s not stopping Google from believing it can get everyone on the planet having an Android device.
When an Android manufacturer wants to include Google applications on devices, they must sign the Mobile Application Distribution Agreement (MADA). This agreement is why Samsung, HTC, Motorola, and a bunch of others can use things like Google Play. Without something like Google Play, users would be left with meager alternatives.
