Problems installing Glassware onto Google Glass - not recognized

When I try to debug the application on the target, these are the log messages:

:13:52 - ApiDemoActivity] Android Launch! [2014-11-28 22:13:52 - ApiDemoActivity] adb is running normally. [2014-11-28 22:13:52 - ApiDemoActivity] No Launcher activity found! [2014-11-28 22:13:52 - ApiDemoActivity] The launch will only sync the application package on the device! [2014-11-28 22:13:52 - ApiDemoActivity] Performing sync [2014-11-28 22:17:37 - ApiDemoActivity] Launch canceled!

Debug mode HAS been enabled on Google Glass and here is the udev rule:

UBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev"
