怎么编译OpenXR的HelloXR例子

DavidChen

首先下载HelloXR的官方代码：

git@github.com:KhronosGroup/OpenXR-SDK-Source.git


可以通过git clone git@github.com:KhronosGroup/OpenXR-SDK-Source.git下载代码（我们的runtime是基于1.0.30这个版本编译的）

helloxr的app代码在路径：OpenXR-SDK-Source/src/tests/hello_xr


因为我们已经适配了Openxr，所以只需要做一个分体式开启应用的适配即可，修改AndroidManifest.xml即可：
1、在application标签下添加

1. <meta-data
   
2.             android:name="yyss.xrapplication"
   
3.             android:value="app" />

复制代码

2、将acitivity标签中的android:resizeableActivity设置成true
3、删除 tools:ignore="NonResizeableActivity"


整体AndroidManifest.xml如下：

1. <?xml version="1.0" encoding="utf-8"?>
   
2. <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   
3.     xmlns:tools="http://schemas.android.com/tools"
   
4.     android:installLocation="auto"
   
5.     android:versionCode="1"
   
6.     android:versionName="1.0">

另外，将OpenXR的runtime apk安装到机器就可以运行了
