Hi There!
I’m working on a standalone app for Oculus Quest 2/3 that uses the OSC protocol. When the app receives an OSC message it crashes but I have some Internet permissions enabled in the Android Manifest. I think I’m obviously ignoring something.
Any advice is well accepted, thanks!
Try to share the errors you get.
My initial guess is that you haven’t initialized your input buffer correctly, so either the receive data process is trying to write outside of the buffer or you are trying to read the data outside of the buffer.
Remember that any OSC message includes:
“OSC Address Pattern” followed by an “OSC Type Tag String” followed by zero or more “OSC Arguments”

hey thanks for the reply, it actually gives me an error on a buffer…how I can fix it?
this is the log:
