Google released its second Android 13 developer preview last Thursday, which includes an important new feature. Now on Android 13, apps will have to ask users for permission to send notifications. iOS has had a similar feature for years, and this is a very practical method to ensure that only certain apps send you notifications.

“Apps targeting Android 13 will now need to ask the user for notification permission before sending notifications,” Dave Burke, Vice President of Android Engineering, wrote in a blog post about Google’s new Android 13 developer preview.

Another big feature in this second preview is Bluetooth Low Energy (LE) Audio support. Bluetooth LE Audio is a new standard that can transmit in higher quality at lower bit rates and uses an audio codec called LC3 for short. This standard was created to provide less energy consumption and better battery life.

In addition to all this, the second Android 13 developer preview includes other improvements, including support for the new MIDI 2.0 standard, which adds higher resolution with 32-bit messages that should provide two-way communication, more precise timing, and a more analog-like feel.
