Android 12 running java example (sample)

[pascalpm]

Anyone found a solution to this? Running the java sample in Android 12 results to (debug mode):

java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for AttributionSource ......

Older Android versions do not ask for this permission and seem to work fine!

R1.15.1
Android Studio Chipmunk 2021.2.1 Patch 1
Sdk 32

Could you describe in more detail what steps did you take that ended up with such result?

[dariuszseweryn]

Could you try out 1.15.2-SNAPSHOT release with DEBUG log level enabled and show the logs that precede the exception?
Instructions how to integrate snapshot repositories are here.

If you could checkout branch fix/permissions_logging, build and run the sample app again and show the logs that precede the exception — it could help me out to diagnose the problem.

Here it is (from the branch "fix/permissions_logging". Hopefully this helps.

[dariuszseweryn]

Awesome, thank you. TIL that calling BluetoothDevice#getName() needs android.permission.BLUETOOTH_CONNECT.

I will need to think if the library should warn the user and return null in case connect permission is not granted or leave it as it is

[dariuszseweryn]

It should be just a formality but you could check fix/sample_scan_device_name branch — it should be working fine. I should merge it somewhere this weekend probably if it works for you.

[pascalpm]

Thanks, but this did not work for me.
Please note that this permission issue happens when you hit the 'START SCAN' button, not when selecting a Bluetooth device! No list is displayed!

[dariuszseweryn]

I have changed the list adapter to use device name from the advertisement class which should not need the permission I think. Unless there is something else now. Could you share what is the exception now?

[pascalpm]

Same exception:
java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for AttributionSource { uid = 10488, packageName = com.polidea.rxandroidble.sample, attributionTag = null, token = android.os.BinderProxy@287f744, next = null }: AdapterService getRemoteName

[pascalpm]

When run for the first time a message will show:
'Allow sample to find, connect to and determine the relative position of nearby devices? Allow/Don't allow'

After pressing 'Allow' the exception is generated in the debugger.

[dariuszseweryn]

There should be no more access to the device name in the code of ScanActivity. Are you able to pinpoint the place / stacktrace of the exception?

I would do it myself but I don't have access to Android 12 phone

[pascalpm]

Thanks for following this through.
As far as I can see the exception is created after executing 'resultAdapter.setOnAdapterItemClickListener(.....' in configureResultList(){...} (ScanPermission.java).

[pascalpm]

I am happy to give you remote access to my PC if you want. If so please send me an email (pascalmater@gmail.com).

[dariuszseweryn]

I think I might have found the problem. Could you pull fix/sample_scan_device_name branch again and re-check?
Thank you for proposing — I hope not to have to take it :)

[pascalpm]

Yes, you did. Thank you very much! Should I close this issue or do you want to add some additional comment?
Again thanks for your help. I can finish my project now.
