Didn't want to ask this because there is a lot of stuff out there on this topic, but I just can't seem to get it working. The main tutorial I've followed can be found here.
I've installed AndroidSerial, exported my project as a signed package, added the device filter lines in AndroidManifest.xml, created the xml directory in the res directory, and copied device_filter.xml into it, but when I try to build it it throws "Error: No resource found that matches the given name (at 'resource' with value '@xml/device_filter')."
I just want to send readable data from my phone to the PC, it doesn't seem like it should be this complicated especially considering it already has built-in console debugging with print()... Any ideas?
