Google Glass Eye手势崩溃(EyeGestureLib) [英] Google Glass Eye Gesture Crashing (EyeGestureLib)
问题描述
我正在尝试使用 EyeGestureLib 从Glass检查Wink.
I am trying to check Wink from Glass using the EyeGestureLib.
I created a new project and did exactly what the guy did with the sample project here.
我的代码的问题部分如下:
The problem part of my code is below:
private EyeGestureManager mEyeGestureManager;
private EyeGestureListener mEyeGestureListener;
private EyeGesture target1 = EyeGesture.WINK;
private EyeGesture target2 = EyeGesture.DOUBLE_BLINK;
在onCreate里面，我有:
Inside onCreate, I have:
mEyeGestureManager = EyeGestureManager.from(this);
mEyeGestureListener = new EyeGestureListener();
// print out each eye gesture is supported or not
for (EyeGesture eg : EyeGesture.values()) {
boolean supported = mEyeGestureManager.isSupported(eg);
Log.d(TAG, eg.name() + ":" + supported);
}
我的程序在打开后立即崩溃.我意识到问题是当它尝试访问时
mEyeGestureManager.使用mEyeGestureManager的代码中的任何位置都会使程序崩溃.根据我观察到的情况，即使在mEyeGestureManager = EyeGestureManager.from(this);
My program crashes immediately after opening. I realize that the problem is when it tries to access
mEyeGestureManager. Any where in the code that uses mEyeGestureManager will make the program crash.According to what I observed, mEyeGestureManager is null even after mEyeGestureManager = EyeGestureManager.from(this);
当我更改
mEyeGestureManager = EyeGestureManager.from(this);
到
mEyeGestureManager = new EyeGestureManager();
它不再崩溃，并且mEyeGestureManager不再为null，但不会检测到眨眼或双眨眼.
it stops crashing and mEyeGestureManager is no longer null but won't detect wink, or double wink.
我的玻璃杯运行的是XE21，但我将其降级为XE18.3，因为我的研究表明 EyeGestureLib 在Glass版本> XE18.3上无法正常工作.
My glass was running XE21 but I downgraded it to XE18.3 because my research shows that EyeGestureLib wont work properly on Glass version > XE18.3.
https://github.com/thorikawa/EyeGestureLib/issues/2
现在我有XE18.3，但是它不起作用.眨眼时我不工作 mEyeGestureManager = new EyeGestureManager(); 然后我得到:
Now I have XE18.3 but it is not working. Wink is not working when I have mEyeGestureManager = new EyeGestureManager(); and I get:
Supported:﹕ BLINK:false
Supported:﹕ DOFF:false
Supported:﹕ DON:false
Supported:﹕ DOUBLE_BLINK:false
Supported:﹕ DOUBLE_WINK:false
Supported:﹕ LOOK_AT_SCREEN:false
Supported:﹕ LOOK_AWAY_FROM_SCREEN:false
Supported:﹕ WINK:false
但是当我有:
mEyeGestureManager = EyeGestureManager.from(this);
它立即崩溃.
我去安装了已经编译好的示例"EyeGestureDemo-debug-1.1.apk" 工作效果很好，但我的效果不好.
I went and installed already compiled example "EyeGestureDemo-debug-1.1.apk" and that WORKED very well but mine does not.
我做错了什么?我已经尝试了3天了. Google对此没有官方的API，但是我不想等到他们发布一个.我的学校项目需要这个. 任何人都知道可能是什么问题吗?
What am I doing wrong? I have been trying to do this for 3 days now. Google doesn't have an official API for this but I don't want to wait till they release one. I need this for my school project ASAP. Anyone got any ideas of what might be the problem?

推荐答案
API很久以前发生了变化(我认为是XE 20左右).
The API has changed a long time ago (around XE 20 I think).
我必须做大量的反思工作才能弄清EyeGestureManager的工作原理.
I had to do quite a bit of digging with reflection to figure out the workings of EyeGestureManager.
这是我的更新版本，以及一些演示用法的示例代码: https://gist.github.com /victorkp/9094a6aea9db236a97f3
Here's my updated version, along with some sample code demonstrating usage: https://gist.github.com/victorkp/9094a6aea9db236a97f3
