我正在开发一个通过 Unity 扩展将 Vuforia 用于 AR/交互式内容的应用程序。我无法弄清楚如何将 Vuforia 集成到应用程序中（以及用于渲染的 Unity）。
我的目标是 Android 2.3.3（API 级别 10）及更高版本。
目前我的应用程序设置为有一个 SherlockFragmentActivity 启动几个后台任务并使用 ViewPager 和 FragmentPagerAdapter 在几个片段之间切换。这些片段之一是 Vuforia 片段。
到目前为止，我尝试的是实例化 UnityPlayer 并在片段的 onCreateView 中返回视图：
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
UnityPlayer mPlayer = new UnityPlayer(this); // Put your activity object here
int glesMode = mPlayer.getSettings().getInt("gles_mode", 1);
boolean trueColor8888 = false;
mPlayer.init(glesMode, trueColor8888);
View view = mPlayer.getView();
return view;
}
但是，当我这样做时，Vuforia 无法加载。Unity 确实加载了，但我得到一个黑屏并且没有来自相机的输出。日志猫：

然后我尝试实例化 QCARUnityPlayer 而不是 UnityPlayer，但随后我得到一个 UnsatisfiedLinkError：

我已经按照本教程以及我能找到的几乎所有其他内容进行操作，但仍然无法弄清楚。
我的片段代码：
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.actionbarsherlock.app.SherlockFragment;
import com.unity3d.player.UnityPlayer;
public class MyFragment extends SherlockFragment {
private UnityPlayer mUnityPlayer;
// UnityPlayer.init() should be called before attaching the view to a layout.
// UnityPlayer.quit() should be the last thing called; it will terminate the process and not return.
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mUnityPlayer = new UnityPlayer(getActivity()); // Put your activity object here
int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1);
boolean trueColor8888 = false;
mUnityPlayer.init(glesMode, trueColor8888);
// Get the view - e.g. to return from the fragment method onCreateView:
View view = mUnityPlayer.getView();
return view;
}
public void onDestroy()
{
super.onDestroy();
mUnityPlayer.quit();
}
// onPause()/onResume() must be sent to UnityPlayer to enable pause and resource recreation on resume.
public void onPause()
{
super.onPause();
mUnityPlayer.pause();
if (getActivity().isFinishing())
mUnityPlayer.quit();
}
public void onResume()
{
super.onResume();
mUnityPlayer.resume();
}
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
mUnityPlayer.configurationChanged(newConfig);
}
// Pass any keys not handled by (unfocused) views straight to UnityPlayer
public boolean onKeyMultiple(int keyCode, int count, KeyEvent event)
{
return mUnityPlayer.onKeyMultiple(keyCode, count, event);
}
public boolean onKeyDown(int keyCode, KeyEvent event)
{
return mUnityPlayer.onKeyDown(keyCode, event);
}
public boolean onKeyUp(int keyCode, KeyEvent event)
{
return mUnityPlayer.onKeyUp(keyCode, event);
}
}
我的问题是，如何强制 Unity/Vuforia 在 SherlockFragment 中工作？
