unity+vuforia+二维码识别

Easy Code Scanner 下载地址：Easy Code Scanner v2.3

本文转载自http://blog.csdn.net/puremilk684/article/details/51479245，经本人验证，可以在安卓平台正常运行，iOS暂时不知，图片系本人实验时截图；以下为原博主内容：在做 Vuforia 的项目时，需要在游戏过程中进行二维码的扫描以进行游戏的激活操作。所以使用了这个Easy Code Scanner插件，Android端和iOS端都可以完美运行使用，非常简单，不需要在Android端和IOS端写原生的代码。

iOS端完全不用自己写东西，直接在unity中照着Easy Code Scanner的例子使用它的接口就可以了。Android端则需要修改一下AndroidManifest（因为项目中还使用了Vuforia，Vuforia自带一个AndroidManifest，需要把这俩个合并一下），Android端的代码就不用改了。

Easy Code Scanner 的 AndroidManifest：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.c4mprod.ezcodescanner"
    android:versionCode="3"
    android:versionName="1.8" >

    <uses-feature android:name="android.hardware.camera.autofocus" />

    <application
        android:debuggable="false"
        android:icon="@drawable/app_icon"
        android:label="@string/app_name" >
        <activity

                <category android:name="android.intent.category.LAUNCHER" />
            intent-filter>
        activity>
        <activity
            android:name="com.c4mprod.ezcodescanner.camera.CameraActivity"
            android:screenOrientation="sensor" />
    application>
manifest>

Vuforia 的 AndroidManifest：

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"

        android:xlargeScreens="true"
        android:anyDensity="true"/>
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

        android:debuggable="false">
        <activity android:name="com.unity3d.player.UnityPlayerNativeActivity"
                  android:label="@string/app_name">

            intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
            <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
        activity>
        <activity android:name="com.unity3d.player.VideoPlayer"
                  android:label="@string/app_name"
                  android:screenOrientation="portrait"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
        activity>
        
        <uses-library android:name="com.ti.s3d" android:required="false" />
        
        <uses-library android:name="com.osterhoutgroup.api.ext" android:required="false" />
    application>
manifest>

合并后的 AndroidManifest：

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
