Bluetooth

Day after day, billions of people all over the world use their Android smartphones to assist them in accomplishing their goals. Android’s ability to perform effectively for each of them is due in part to a collaborative effort with you, our developer community, who share input to help us improve Android.

With the Android 13 Developer Preview 1, we’re giving you a first peek at the future version of Android. We’re continuing some essential themes in Android 13, including privacy and security, as well as developer productivity. We’ll also expand on some of the more recent changes from 12L to help you make use of the 250 million or more large-screen Android smartphones now in use.

This is only the beginning of Android 13, and we’ll have plenty more to offer as the rollout progresses. Read on for a taste of what’s new, then go over to the Android 13 developer site for more information on Pixel downloads and the release schedule. As always, getting your input early is critical to ensuring that it is included in the final version. We’re excited to hear your feedback, and we appreciate your ongoing support in making Android a platform that works for everybody! 

Themed application icon

In Android 13, we’re extending Material You dynamic colour beyond Google applications to all app icons, allowing users to choose between icons that inherit the hue of their wallpaper and other theme settings and icons that don’t. Only a monochrome app icon (for example, your notification drawable) and a change to the adaptable icon XML are required from your app. All developers are encouraged to supply suitable icons to allow users who have opted in to enjoy a consistent experience. Themed app icons are currently only available on Pixel smartphones, but we’re working with our device maker partners to expand their availability.

Users may choose to have customised app icons starting with Android 13. This feature tints app icons incompatible with Android launchers to match the colour scheme of the user’s wallpaper and other themes.

To use this functionality, your app must have a monochromatic app icon that is linked from the manifest’s adaptive-icon> element. If a user has activated the Themed icons toggle on their device, the system determines the tint colour by looking at the colour of the user’s wallpaper and theme, which it then adds to the monochromatic app icon.

Specifications

The following requirements should be met by your monochromatic app icon:

It must be in SVG format and not a photograph.

We propose that the logo be contained within a 90 × 90 dp container with a 36 x 36 dp area. If the logo must be larger, it must be at least 60 × 60 dp.

You may utilise the alpha gradient if your logo is three-dimensional.

➊Container area (90 x 90 dp).

➋ Logo area (36 x 36 dp recommended, 60 x 60 dp maximum).

At the heart of it, all are privacy and security

People would like an operating system and apps they can trust with their most private and sensitive data. Android 13 focuses on establishing a responsible and high-quality platform for everybody by delivering a safer environment on the device and more controls to the user, which is central to Android’s product principles. We’re adding a picture picker in today’s release to allow users to safely share photographs and videos with applications, as well as a new Wi-Fi permission to reduce the requirement for apps to have location permission. We propose that you check out the new APIs and see how they affect your project.
