We use this project to listen for broadcasted UDP messages. Those UDP messages are broadcasted to the whole network (using 255.255.255.255 IP mask.
For some Android devices, this works fine, for others it does not. I created a blank native App to analyse this problem further, and it seems that it works, when the MulticastLock is acquired.
I scanned the source code, it seems that the MulticastLock is acquired when adding a membership.
But I did not find out how to use this, and how to add a membership as a UDP listening App. Which multicastAddress I am supposed to put there?
Do you have an example or some hints how to do this? Is this already implemented in 4.1.7?
