Question

我有问题根据此tutorial为Google Glass创建基本应用程序。我有2节课。我跟着教程完全一样，但我在谷歌眼镜中找不到它。我试过“Ok Glass”，但我也找不到它。我创建了2个类，第一个是HelloWorldActivity.java。这个类是一个Activity类。这是HelloWorldActivity.java

public class HelloWorldActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Card myCard = new Card(this);
    myCard.setText("Hello, World!"); 
    myCard.setFootnote("First Glassware for Glass"); 
    View cardView = myCard.getView();       
    // Display the card we just created
    setContentView(cardView);
}


}

第二个是HelloGlass.java这个类是一个可识别语音命令的Service类。

public class HelloGlass extends Service {

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}

public int onStartCommand(Intent intent, int flags, int startId) {

    Intent i = new Intent(this, HelloWorldActivity.class);
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);
    return START_STICKY;
   } 
}

我创建了必要的xml文件，包括voice_trigger_start.xml。这是andorid清单

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.app.helloglass"
    android:versionCode="1"
    android:versionName="1.0" >

        <uses-sdk
            android:minSdkVersion="8"
            android:targetSdkVersion="19" />

        <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name" >
            <activity
                android:name=".HelloWorldActivity"
                android:label="@string/app_name"
                android:enabled="true" >
            </activity>
             <service
                android:name="com.app.helloglass.HelloGlass"
                android:enabled="true"
                android:exported="true"
                android:icon="@drawable/ic_launcher"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
                </intent-filter>  
                <!-- Voice command found in res/xml/voice_trigger_start -->
                <meta-data
                    android:name="com.google.android.glass.VoiceTrigger"
                    android:resource="@xml/voice_trigger_start" />
            </service>
        </application>

    </manifest>

有人知道我错过了什么吗？我试图运行它，但我找不到它。

编辑：

添加权限后，语音命令工作正常，但应用程序崩溃，因为清单中的包名称错误。

See the whole update project on my GitHub.

The tutorial使用自定义语音命令。您需要在清单中使用此权限：

<uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />

请参阅Why is my voice command missing from the ok glass menu in XE16?和https://developers.google.com/glass/develop/gdk/voice

你能试试这个清单吗？
