iBeacon not working with Android 12 #1067

Closed assembleMHN closed 2 years ago

assembleMHN commented 2 years ago

Hi guys.

Thank you for all your hard work. I have an issue with the library i hope you can help with :)

We have an older app, using android-beacon-library to recognize ibeacons. I have a physical android 10,11,12 laying on the table in front of me running the exact same codebase. I have a beacon simulator on my iPhone. When i activate the beacon Android 10 and 11 get the signal imidiatly, but the Android 12 device never reacts. I have tried everything, and google i cannot find the reason why the exact same codebase works on 8,9,10,11 but not 12.

Im using the newest version of the library org.altbeacon:android-beacon-library:2.19.2

All the code runs on Android 12, exactly as on 10 and 11 but 

       override fun didEnterRegion(region: Region) {
            ApplicationContext.addLocationTime(true, beaconStatusKeyBuilder(region))
            if (!ApplicationContext.isActivityVisible()) {
                val date = Date(System.currentTimeMillis())
                val cal = Calendar.getInstance()
                cal.time = date
                if (beaconNotificationCooldown(region)) {
                    ApplicationContext.addLocationNotification(beaconStatusKeyBuilder(region))
                    callback.sendNotification()
                }
            }
        }

        override fun didExitRegion(region: Region) {
            ApplicationContext.addLocationTime(false, beaconStatusKeyBuilder(region))
            beaconCoolDownPeriod!!.postDelayed(beaconCoolDownPeriodRunnable, coolDownPeriodInSeconds * 1000)
        }

Is never called.

I hope somebody can help me out, or give some input :)

Best Regards Morten

Google changed the way bluetooth permissions work for apps targeting Android 12+. If you are targeting Android 12 (targetSdkVersion 31 in your build.gradle file), you will also need to declare the following permission in your manifest and request it at runtime from the user: BLUETOOTH_SCAN

An easier solution is to change your targetSdkVersion 30 so that the same permission structure for earlier Android versions works with Android 12 devices. Read more here:

I have the permission declared in my Manifest and do request it at runtime, yet the scanning fails with the following logs when the app is killed and relaunched.

Here is my declaration in the manifest

  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"

  <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
  <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
  <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

What exactly could be the issue, please?
