A few days ago we reported that Google is prepping the launch of Android 11, and while Google did take down the link to the developer preview website, it did hint that the launch was imminent. What we did not anticipate was how quickly Google will release the Android 11 Developer Preview.

This is the first time Google has released the preview ahead of the usual launch window. Google normally aims for the second week of March but seems like the company is eager to let the developers test out what they have been cooking. This also means that developers are going to be getting more time testing out and providing feedback.
