On my network I've started to see the ConnectivityService broadcast android.net.wifi.LINK_CONFIGURATION_CHANGED intents every time a UDP packet is being sent. It prevents the response from coming back.
Whenever the link configuration is changed, it flips between one of two IPv6 addresses. Does anybody know how the best way to handle this case? I need to be able to send out a UDP packet and read the response. Here's what I think the relevant source file is: https://android.googlesource.com/platform/frameworks/base/+/be9ee6a498afc08df1ca6d796b703b703b25c9a9%5E!/ Here's a log of the intent: <--- UDP Packet is sent here, and instead of the response I see this intent.
