Receiving Broadcast Error For Bluetooth Discovery - Error In Onreceive() Method That Receives Intents By Startdiscovery() Method

I am facing a problem in device scan activity. I want to scan all bluetooth devices in vicinity and print them on UI. But i am getting the same run time error as in Receiving broad

Solution 1:

device.getUuids() - here you have a Null, that is why you have an error here. Check this variable beforе using it.
