IllegalStateException: Too many receivers

Hello!

I am trying to connect to a LE device periodically via WorkManager. On certain devices I am getting the following crash. Is there any situation when we are leaking some receiver instance?

Do we have to close some resources after job done to unregister the receiver which no.nordicsemi.android.ble.BleManager may be using?

Thanks!

You may try canaryleak library from Square to investigate the leaks.

I was interested whether you’re getting a logs about closing the managers. If you override log(...) method, and override getMinLogLevel() to return Log.DEBUG, you should see e.g. where “close()” is called, etc.

I’m waiting for updates regarding a single manager instance.
