Google releases second Android 13 developer preview to improve notification push permission settings

In recent months, the development of Android 13 has been progressing quite smoothly. About a month after the launch of the first developer preview version (codenamed Tiramisu), we ushered in the second Developer Preview. It can be seen that in order to reflect the latest changes, DP2 designed specifically for developers still has no direct OTA update option-unless you have already installed DP1 .

If you happen to have a Pixel 6 / 6 Pro, Pixel 5 / 5a 5G, Pixel 4 / 4 XL / 4a / 4a 5G, you can now experience Android 13 Developer Preview 2 on your real device (or use an emulator image to try it out).

Last month's first developer preview version gave us a preliminary understanding of the user experience of Android 13. However, the second developer preview version pushed today mainly focuses on improving developer functions.

One exception is that apps must now request permission to send notifications to users. (Although Google emphasized this today, we are not surprised by this Android 13 experience improvement)

As with other permissions, users can choose whether to allow a specific app to send notifications. If it has been installed before, the app can also inherit the previous settings.

On the other hand, developers must ensure that they provide users with enough control and context to allow them to choose whether to release.

Speaking of permissions, through a newly added API, Android 13 DP2 now also allows applications to be easily downgraded when unnecessary.

Another feature is designed to ensure that apps cannot receive messages from other apps - unless the developer explicitly requests it.

It is worth mentioning that Android 13 DP2 supports the MIDI 2.0 standard (musicians rejoice):

Users can connect MIDI 2.0 hardware to Android devices via USB, and support for Bluetooth LE Audio is also available.

As well as sharing and broadcasting audio with others, subscribing to public broadcasts for information and accessibility, all while consuming less electricity.

In addition, Android 13 will support vector fonts that follow the COLRv1 format, and Google has also converted its system emojis to this format. Thanks to the characteristics of vectors, the file size becomes smaller, and there will be no mosaics no matter how you scale it.

For users of non-Latin scripts, Android now prevents unexpected clipping by adjusting the line height for each language (improving display for languages ​​like Tamil, Burmese, Telugu, and Tibetan).

Finally, for users of phonetic input methods such as Chinese and Japanese, Android 13 introduces a new text conversion API so that Japanese users can enter hiragana and immediately see Kanji search results (skipping the current complicated four-step process).
