Android development is monthly these days, so it’s no surprise that about a month after Google announced the first developer preview of Android 13 (codenamed “Tiramisu,” as Google occasionally calls it in its developer documentation), it’s now launched the second developer preview.

These previews usually still have a lot of rough edges and are intended for developers, so as with the first preview, there is no over-the-air installation option (although if you have the first preview installed, you can install the second as an over-the-air preview). -air -the-air-update). Google has made available 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 the Android Emulator.

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

The one exception to this is that users will definitely notice that apps now have to ask for permission to send you notifications (although Google emphasizes this today, this has been a known feature of Android 13 for a while). As with other permissions, apps now have to ask you if they can send notifications and this is an opt-in process. If you’ve ever installed an app that immediately sends you a plethora of notifications, you’ll love this. On the other hand, developers need to make sure that they give users enough control and context to make sure they sign up.

Speaking of permissions, developers can now also downgrade their apps’ permissions when they no longer need them. Android 13 is getting a new API that makes it easy for them to do this.

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 you to connect MIDI 2.0 hardware to Android devices via USB, as well as support for Bluetooth LE Audio, which offers features such as the ability to transfer audio sharing and broadcasting to others, as well as subscribing to public broadcasts for information and accessibility – and, as the name implies – it consumes less power.

Android 13 also supports vector fonts that conform to the COLRv1 format and Google is moving its system emoji to this format as well. Since these are vectors, their file sizes are smaller and can be displayed at any size without pixelation.

For those using non-Latin scripts, Android 13 now improves the display of languages ​​such as 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 now introduces a new text conversion API so that a Japanese user can type Hiragana and immediately see the Kanji search results live, taking today’s more complicated four-step process. is skipped.
