与 android manifest 上的活动标签冲突：Unity3d 中的 Facebook 和 Prime31 插件

Question

我正在尝试让一个项目同时使用 Facebook Unity 插件和（几个）Prime31 插件。我正在尝试创建自己的活动来扩展 Prime31 活动，并结合此处给出的 Facebook 解决方法：Conflict with activity tags on android manifest: Facebook and Google Play Games in Unity3d

到目前为止，我的课程看起来像这样：

import android.content.Intent;
import android.os.Bundle;
import com.facebook.Session;

public class DQUnityPlayerActivity extends com.prime31.UnityPlayerProxyActivity
{
  @Override
  protected void onCreate(Bundle arg0) {
    super.onCreate(arg0);
  }

  @Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
  } 
}

我用javac编译了它，打包成一个.jar文件，放到/Assets/Plugins/Android中。我像这样修改了我们的 AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player" android:installLocation="preferExternal" android:theme="@android:style/Theme.NoTitleBar" android:versionCode="1" android:versionName="1.0">
  <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity="true" />
  <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="true">
    <activity android:name=".DQUnityPlayerActivity" android:screenOrientation="sensorLandscape" android:launchMode="singleTask" android:label="@string/app_name" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
etc...

现在我遇到了困难：此时，当我尝试在我的测试设备上运行它时，找不到该类。亚行向我展示了这一点：

知道可能出了什么问题吗？

您需要将导出的 jar 文件放在 Assets/Plugins/Android/ 文件夹中，并确保在 DQUnityPlayerActivity 类中有以下行： package com.dqsoft.ChampHearts;
