Runtime exception raised in the Google Play console

Hi @CodeMinion ,

I get an error raised in play console this last days. No problem so far, just the last few days.

Error type is: java.lang.NullPointerException

Stacktrace is:

Exception java.lang.NullPointerException: bluetoothDevice.name must not be null
  at com.rouninlabs.another_brother.method.GetBluetoothPrintersMethodCall$execute$1.invokeSuspend (GetBluetoothPrintersMethodCall.java)
  at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith (BaseContinuationImpl.java)
  at kotlinx.coroutines.DispatchedTask.run (DispatchedTask.java)

  at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.runWorker (CoroutineScheduler.java)
  at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.run (CoroutineScheduler.java)

I have take a look at source code and it seems like the printer modelName is empty.

Here is the source code i use to detect BT printers :

     List<brother.BluetoothPrinter> printers =
        await printer.getBluetoothPrinters(
      [
        brother.Model.QL_820NWB.getName(),
        brother.Model.TD_2125NWB.getName(),
      ],
    );

The problem seems to arrive exclusively on OPPO OPD4A1L1 (OPPO Reno7 5G/Find X5 Lite) device, running Android 13 API 33.

Have you noticed this error before?

Sincerely, Alain Deseine.

Hi @alaindeseine ,

Thank you for reporting this issue. I have released version 2.1.1 of another_brother, that will properly handle the cases where the device name is null but this seems to be a deeper issue. I found a mentions of cases where BT devices are reporting a null name in Android 13 https://issuetracker.google.com/issues/240485116?pli=1

So while with this version you will not see the error, it's likely the printers won't appear while running in Android 13 in those devices.

Thanks again for the support,

Hi @CodeMinion,

Thanks for replying.

I will update the lib as soon as possible.

Thanks again.
