Using the "Run as" menu in Eclipse will only install the APK on the device but won't run it, because none of the application components in the manifest have android.intent.category.LAUNCHER
.
Instead, after the APK is installed, you can use the voice trigger on Glass to start it. For example, say "ok glass, show a compass" for the Compass sample. This will start the CompassService
service that publishes the live card to the timeline.
