Android’s lengthy standing doc picker permits a consumer to share particular paperwork of any kind with an app, with out that app needing permission to view all media information on the machine. The photograph picker extends this functionality with a devoted expertise for selecting pictures and movies. Apps can use the photograph picker APIs to entry the shared pictures and movies with no need permission to view all media information on the machine. We plan to deliver the photograph picker expertise to extra Android customers via Google Play system updates, as a part of a MediaProvider module replace for gadgets (excepting Go gadgets) working Android 11 and better. Give photograph picker APIs a attempt to tell us your suggestions!

Close by machine permission for Wi-Fi – Android 13 introduces the NEARBY_WIFI_DEVICES runtime permission (a part of the NEARBY_DEVICES permission group) for apps that handle a tool’s connections to close by entry factors over Wi-Fi. The brand new permission will probably be required for apps that decision many commonly-used Wi-Fi APIs, and permits apps to find and hook up with close by gadgets over Wi-Fi with no need location permission. Beforehand, the placement permission necessities had been a problem for apps that wanted to connect with close by Wi-Fi gadgets however didn’t really want the machine location. Apps focusing on Android 13 will probably be now in a position to request the NEARBY_WIFI_DEVICES permission with the “neverForLocation” flag as a substitute, which ought to assist promote a privacy-friendly app design whereas lowering friction for builders.

Developer productiveness and instruments

Android 13 additionally brings new options and instruments for developer productiveness. Serving to you create stunning apps that run on billions of gadgets is one in all our core missions – whether or not it’s in Android 13 or via our instruments for trendy Android growth, like a language you’re keen on in Kotlin or opinionated APIs with Jetpack. By serving to you’re employed extra productively, we purpose to decrease your value of growth so you’ll be able to give attention to persevering with to construct wonderful experiences. Right here’s a few of what’s new in immediately’s launch.

Fast Settings Placement API – Fast Settings within the notification shade is a handy manner for customers to vary settings or take fast actions with out leaving the context of an app. For apps that present customized tiles, we’re making it simpler for customers to find and add your tiles to Fast Settings.

Programmable shaders – Android 13 provides help for programmable RuntimeShader objects, with conduct outlined utilizing the Android Graphics Shading Language (AGSL). AGSL shares a lot of its syntax with GLSL, however works throughout the Android rendering engine to customise portray inside Android’s canvas in addition to filtering of View content material. Android internally makes use of these shaders to implement ripple results, blur, and stretch overscroll, and Android 13 allows you to create related superior results in your app.

OpenJDK 11 updates – In Android 13 we’ve began the work of refreshing Android’s Core Libraries to align with the OpenJDK 11 LTS launch, with each library updates and Java 11 programming language help for app and platform builders. We additionally plan to deliver these Core Library modifications to extra gadgets via Google Play system updates, as a part of an ART module replace for gadgets working Android 12 and better. Study extra.

App compatibility

With every platform launch we’re working to make updates sooner and smoother by prioritizing app compatibility as we roll out new platform variations.
