The Android Companion Device Manager functionality is not working on the Galaxy S21 with Android 14. I have built a minimalist reference application and confirmed it works as expected on Galaxy S22, S23 and ZFold with Android 14 , but does not work on the S21 with Android 14.
The specific problem is that the dialog described in Figure 2 on this page never displays: Companion device pairing | Connectivity | Android Developers even though the device is discovered and the callback is executed here:
override fun onAssociationPending(intentSender: IntentSender) {
intentSender?.let {
startIntentSenderForResult(it, SELECT_DEVICE_REQUEST_CODE, null, 0, 0, 0)
}
}
A minimalist app demonstrating this problem with instructions is here:
