Android development happens on a monthly basis these days, so it’s no surprise that it’s been almost a month since Google announced the first developer preview of Android 13 (codenamed “Tiramisu,” as Google sometimes calls it in developer documentation). Now it’s running. second. Developer overview.

These pre-releases usually still have a lot of rough edges and are meant for developers, so there is no over-the-air installation option in the first pre-release (although if you have the first pre-release installed, you can install the second one). set as wireless preview). -air-air-updates). Google has provided system images for the Pixel 6 Pro, Pixel 6, Pixel 5a 5G, Pixel 5, Pixel 4a (5G), Pixel 4a, Pixel 4 XL, and Pixel 4, as well as Android emulators.

While the first preview gave us a glimpse of the user experience in Android 13, today’s update is mainly focused on developer features.

The one exception to this is that users will notice that apps must now ask for permission to send you notifications (although Google is pushing for this today, it’s been a known feature of Android 13 for some time). Like other permissions, apps will now have to ask you if they can send notifications, and that’s the consent process. If you’ve ever installed an app that sends you tons of notifications right away, you’ll love this one. Developers, on the other hand, need to make sure they give users enough control and context to ensure they sign up.

Speaking of permissions, developers can now lower the permissions of their apps even if they no longer need them. Android 13 is getting a new API to make it easier for them.

The new version of the operating system also introduces a new feature that prevents apps from receiving messages from other apps unless the developer explicitly wants it to.

Also new in this preview is support for the MIDI 2.0 standard (musicians rejoice), which now allows MIDI 2.0 hardware to be connected to Android devices via USB, as well as support for Bluetooth LE audio, which allows streaming. . Sharing and streaming audio to others, and subscribing to public broadcasts for information and access – and, as the name suggests, use less power.

Android 13 also supports vector fonts that follow the COLRv1 format, and Google is also converting its system emoji to this format. Because they are vectors, they have a small file size and can be displayed at any size without being pixelated.

For those using non-Latin scripts, Android 13 now improves performance for languages ​​like Tamil, Burmese, Telugu, and Tibetan by adjusting the line height for each language to prevent clipping. And for those who use phonetic letter input methods for languages ​​such as Japanese and Chinese, Android 13 is now introducing a new text conversion API so that a Japanese language user can type hiragana and see real-time kanji search results immediately, adopting today’s more complex four step process. abandoned.
