Android O Developer Preview 3 is now available for anyone to download and try out to see what are the new changes included by Google. The latest preview version has been released with one month of the Developer Preview 2 which was made available during Google I/O 2017 where it also announced Android O Beta program.
The latest developer preview release also answers one of the commonly asked questions as it confirms that Android O will indeed be Android version 8.0. Other than this, it brings final Android O APIs (API level 26) and official SDK which means developers can start making their apps compatible with the next Android version. They can also start publishing those apps to the Play Store so that when Google releases Android O to masses, their apps start working with the new version instantly.
This is the penultimate release from Google which means there will be one more developer preview release before Android O is released for public and source code is sent to OEMs to make their own changes to make it compatible with their devices and custom UIs/skins. And as it is said, the developer preview can be downloaded and installed but there are still chances of running into bugs and other performance related hiccups. It means you are not recommended to install it on your daily driver yet.
If you are an Android Beta Program member, you will be getting the latest developer preview as an OTA update anytime soon. But if you are not or you don’t want to wait for the update, you can download the flash image file for your particular device and start exploring.
