If I debug an android application without signing it, everything works as expected - GDB connects up, and I can break into the code and step through it etc.
However, if I sign my package with a key (Run Settings/Deployment/Sign Package) for a Debug build configuration, GDB fails to connect.
Below is sample logcat output that shows the debug failure. The application still runs, but cannot be debugged.
