如何在android应用程序中使用droidAR？

Question

我尝试在我的Android AR项目中使用droidAR。我从here找到了一个例子并完成了所有步骤。我下载了droidar-master.zip并提取了C:/Documents。我在C:/Documents下创建了一个名为WorkspaceAR的文件夹。我在WorkspaceAR打开eclipse。

我将我的测试项目作为android应用程序运行。控制台消息如下：

[2015-04-28 10:28:10 - TestProject] ------------------------------
[2015-04-28 10:28:10 - TestProject] Android Launch!

eclipse包explorer的屏幕截图如下：

我项目的AndroidMAnifets.xml：

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

</application> 

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-feature android:glEsVersion="0x00020000" />

<supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true" />

我的真实设备连接到电脑后运行测试项目。但我什么也看不见。该应用程序无法启动。
