Introducing Android Q Beta – On March 13, Beta 1 of Android Q was released for early adopters along with a preview SDK for devs. This post outlines the changes that Google has announced so far, including some future-proofing support for foldable devices, as well as more immediately useful features such as a quicker sharing shortcut, quick settings, wider support for Vulkan, and the ability to grab dynamic depth images. And of course, there are the usual improvements to security and privacy to consider. More soon.
Android Q Beta 2 – Google announced the second Android Q developer preview on the Android Developers Blog. Key features include a new foldables emulator, a new MicrophoneDirection APIR, Google’s own take on floating chat heads – called Bubbles – and more.
Introducing a new Google Play app and game icon specification – As of May 1, all new apps uploaded to the Play Store will need to conform to new icon standards.

Giving users more control over their location data – Every time Google makes a change to streamline and improve the experience for users, it equates to a headache for us devs! In Android Q, users will have more control over location permissions, which means they’ll be able to opt for apps to only access location data while “in use”. Devs will need to add a new permission to the manifest and manage the new setting. The new feature is available to test in Q Beta, and you can find more info in the post.
Google Mobile Developer Day at Game Developers Conference – Stadia may be the big gaming announcement from Google, but the company hasn’t left us traditional mobile devs completely in the lurch.
