Running Timer, Stopwatch, and Compass example on Glass doesn't seem to work

问题

I ran the timer, stopwatch, and compass example here:

https://developers.google.com/glass/develop/gdk/quick-start#for_android_beginners

However, the application builds but doesn't run. This is all I can get in logcat:

I'm using

Eclipse Standard/SDK

Version: Kepler Release Build id: 20130614-0229

回答1:

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.

In addition to use voice trigger or touch menu to launch, you can also use adb command to launch the service, this will save some time, because it gets kind of old to manually navigate to launch the app.

adb shell am startservice com.google.android.glass.compass/com.google.android.glass.sample.compass.CompassService 
adb shell am startservice com.google.android.glass.timer/com.google.android.glass.sample.timer.TimerService
adb shell am startservice com.google.android.glass.stopwatch/com.google.android.glass.sample.stopwatch.StopwatchService:

adb shell am startservice <name of service>
adb shell am start <name of activity>

Please make sure you have XE11 update, otherwise it wont' work.

回答4:

You can also edit the debug configuration. The second section should have a launch activity option. Since you don't have a default (because it is triggered by the voice intent) you can select one from the project manually. this will then auto launch the main activity when you debug the application.
