实现谷歌玻璃低频卡直播 [英] Implement low-frequency live card in google glass
本文介绍了实现谷歌玻璃低频卡直播的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试使用在 GDK提供的指令，以实现低频直播卡导游的。
我有我想要呈现布局和LiveCard服务类（扩展服务）。我也有菜单：活动处理菜单回调，使得菜单透明的，并且在LiveCard服务使用的setAction（）为卡的动作提供的PendingIntent。
我加载应用到玻璃时，也得到了成功的消息，但它并不在我的玻璃出现。
我不知道还有什么缺失。

解决方案
下面是原来的答案，因为我已经做了一个参考项目，是以谷歌文档和使用秒表项目作为参考更新它XE16。检查code和提交历史学会了很多：
的https://github.com/mscheel/GoogleGlass-XE16-LowFrequencyLiveCardBasketballScore
一种方法是申报语音触发启动服务/ livecard。
这是这个模式的解释中提到：
https://developers.google.com/glass/develop/patterns/正在进行的任务
的技术是这里描述
的https://developers.google.com/glass/develop/gdk/starting-glassware#unlisted_commands
我与你code测试了它和它的工作，如果清单的这些项目（修改当然是你的包名）......这第一个进入该应用程序标签中：

您还需要：
＆LT;使用许可权的android：NAME =com.google.android.glass.permission.DEVELOPMENT/＆GT;
您还需要这个文件...... RES / XML / voice_trigger.xml：

我发现定时器项目将在想出这个有用，这里是它的清单：

I try to implement low-frequency Live Card using the instruction provided in the GDK guides. I have a layout that I want to render and the LiveCard service class (that extends Service). I also have the Menu: activity to handle menu callbacks, making the menu transparent, and provide a PendingIntent for the card's action using setAction() in the LiveCard service.
I also got a successful message when loading the app into Glass but it doesn't show up in my Glass. I'm not sure what else is missing.

and here is my Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.coeverywhere.google_glass"
android:versionCode="5"
android:versionName="1.0" >

and here's my voice_trigger_start.xml. I put them under res/xml
<?xml version="1.0" encoding="utf-8"?>
<trigger command = "basketball" />
解决方案
Below is original answer, I have since made a reference project that takes the Google documentation and updates it for XE16 using the StopWatch project as a reference. Check the code and commit history to learn a lot more:
https://github.com/mscheel/GoogleGlass-XE16-LowFrequencyLiveCardBasketballScore
One way is to declare a voice trigger to start the service/livecard.
This is mentioned in this pattern explanation:
https://developers.google.com/glass/develop/patterns/ongoing-task
The technique is described here:
https://developers.google.com/glass/develop/gdk/starting-glassware#unlisted_commands
I tested it out with your code and it worked if the manifest has these items (modify for your package name of course) ... this first one goes inside the application tag:
<service
android:name="com.example.lowfrequencylivecardexample.LiveCardService"
android:enabled="true"
android:exported="true"
android:label="@string/app_name" >
<intent-filter>
<action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
</intent-filter>
<meta-data
android:name="com.google.android.glass.VoiceTrigger"
android:resource="@xml/voice_trigger" />
</service>
You also need:
<uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />
You will also need this file ... res/xml/voice_trigger.xml:
<?xml version="1.0" encoding="utf-8"?>
<trigger keyword="basketball" />
I found the Timer project to be helpful in coming up with this, here is its manifest:
https://github.com/googleglass/gdk-timer-sample/blob/master/AndroidManifest.xml
Optionally you can make the home team the Celtics and the away team the Lakers. Larry Legend forever!
