我正在尝试将从 3ds max 生成的 obj 文件加载到 android 中，并进行了以下编码，但收到了我解决的错误，但无法找到我错的地方。

Min3dTest.java

package com.min3dtest;
import android.os.Bundle;  
import android.app.Activity;  
import android.content.Intent;  
public class Min3dTest extends Activity {  
  /** Called when the activity is first created. */  
  @Override  
  public void onCreate(Bundle savedInstanceState)   
  {  
    super.onCreate(savedInstanceState);  
     this.startActivity( new Intent(this,Obj3DView.class));  
  }  
}

Obj3DView.java

 package com.min3dtest;   
    import min3d.core.Object3dContainer;  
    import min3d.core.RendererActivity;  
    import min3d.parser.IParser;  
    import min3d.parser.Parser;  
    import min3d.vos.Light;  
    public class Obj3DView extends RendererActivity {  
      private Object3dContainer faceObject3D;  
      /** Called when the activity is first created. */  
      @Override  
      public void initScene()  
      {  
        scene.lights().add(new Light());  
        scene.lights().add(new Light());  
        Light myLight = new Light();  
        myLight.position.setZ(150);  
        scene.lights().add(myLight);  
        IParser myParser = Parser.createParser(Parser.Type.OBJ, getResources(), "com.example.min3dtest:raw/updatedfloor00_obj",true);  
        myParser.parse();  
        faceObject3D = myParser.getParsedObject();  
        faceObject3D.position().x = faceObject3D.position().y = faceObject3D.position().z = 0;  
        faceObject3D.scale().x = faceObject3D.scale().y = faceObject3D.scale().z = 0.009f;  
        // Depending on the model you will need to change the scale faceObject3D.scale().x = faceObject3D.scale().y = faceObject3D.scale().z = 0.009f;  
        scene.addChild(faceObject3D);  
      }  
      @Override  
      public void updateScene() {  
        faceObject3D.rotation().x += 0.5;  
        faceObject3D.rotation().z += 1;  
      }  
    }

我已经设法让它正常工作，但我不能确定你的情况可能是什么问题。我看到的唯一与我的示例不同的是 AndroidManifest.xml Mine 的外观如下：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.a"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity   
   android:name=".Obj3DView"   
   android:label="@string/app_name">  
    </activity> 
    <activity
        android:name="com.example.a.Min3dTest"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>
