After I upgraded the system to Android 12, Bluetooth pairing was no longer supported. Why?

Last Updated on：2025-02-27 06:02:44

Google has added some Bluetooth permissions to Android 12. If your App is compiled based on SDK 31 or above, you need to enable three permissions, namely BLUETOOTH_SCAN, BLUETOOTH_CONNECT, and BLUETOOTH_ADVERTISE, for Bluetooth pairing. If your App is compiled based on a version earlier than SDK 31, you can use Bluetooth pairing with the old permissions on Android 12. For more information, visit https://developer.android.com/guide/topics/connectivity/bluetooth/permissions.

Why can't I perform pairing for an offline Bluetooth lock right after I remove it from the app?

Why does the app remain on the upgrade screen for a long time and cannot exit after a device upgrade failure and restart?
