We recently ran into the same problem when building for Android 12 and above, given that Google are now expecting every new app to target Android 12 (31+). A number of things need changed to get this to work.

NOTE - These changes have only been tested on our side for ranging with iBeacons.

Now instead of BLUETOOTH and BLUETOOTH_ADMIN we now only need BLUETOOTH_SCAN.

So your permission for Bluetooth in you Android Manifest should look like:

<!-- Replace both of these -->
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<!--  -->

<!-- With this -->
<uses-permission android:name="android.permission.BLUETOOTH_SCAN"/>
<!--  -->

NOTE - You also need to change the required permissions in manifest for this library to the above. Again you only need BLUETOOTH_SCAN in the library manifest.

If you aren't already you also need to ask for both ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.

See permissions changes here: Android 12 Changes

We have forked this library to maintain it for more recent versions of RN, Android and iOS.

Our Fork: Here

If you don't want to use our fork, simply just update the permissions as I have described above and update the Altbeacon version to 2.19.4 as done here: #237

We know our version of the library works for RN up to:

  "react": "18.0.0",
  "react-native": "0.69.7",

I hope this solves your problems!

It's working!

  "react": "17.0.2",
  "react-native": "0.65.3",

compileSdkVersion = 33
targetSdkVersion = 32

Hi @mattia-beta

Do you have working code in android?

Worth to mention, BLUETOOTH_SCAN requires a runtime permission prompt.
@Jake-Young's fork works perfectly in that case!
