Android UnityPlayerPractivity未获取onCreate（）日志

我试图在docs.unity3d的帮助下扩展UnityPlayerPractivity。我有一个带有MainActivity类的简单jar文件，还将classes.jar文件包含在libs文件夹中。我的类文件有以下代码

package com.example.testactivity;

import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import com.unity3d.player.UnityPlayerActivity;

public class MainActivity extends UnityPlayerActivity
{

@Override
public void onCreate(Bundle savedInstanceState) {
  Log.i("Hiren","==============ON CREATE CALLED==============");
  super.onCreate(savedInstanceState);
}


public static void callMe()
{
   Log.i("Hiren","==============Function CALLED==============");
}
}

我可以通过我的c#脚本调用静态函数callMe（），但在活动开始时不会调用onCreate（）。我的C#脚本是

private static FBShare _instance;

public static FBShare Instance
{
get
{
  if(_instance == null)
     _instance = new FBShare();
  return _instance;
}
}

private AndroidJavaClass cls_Fb = new AndroidJavaClass("com.example.testactivity.MainActivity");

public void CallMe()
{

  using(AndroidJavaClass cls_UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
  {

    using(AndroidJavaObject obj_Activity = cls_UnityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
    {
      cls_Fb.CallStatic("callMe");
    }
  }

私有静态FBShare\u实例；
公共静态共享实例
{
得到
{
if（_instance==null）
_实例=新FBShare（）；
返回_实例；
}
}
私有AndroidJavaClass cls_Fb=新的AndroidJavaClass（“com.example.testactivity.MainActivity”）；
public void CallMe（）
{
使用（AndroidJavaClass cls_UnityPlayer=新的AndroidJavaClass（“com.unity3d.player.UnityPlayer”））
{
使用（androidjavaobjectobj_Activity=cls_UnityPlayer.GetStatic（“currentActivity”））
{
cls_Fb.CallStatic（“callMe”）；
}
}

当我调用“CallMe”方法时，我得到了被调用的日志。但是我没有从onCreate（）得到任何日志

AndroidMenifest.xml文件包含

正如尼古拉斯所说，检查舱单 确保此部分正确无误

<activity
    android:name=".MainActivity"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
             <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

猜测问题出在AndroidManifest.xml文件上，尝试绕过它，我们可以检查问题。清单文件看起来很好，如unity网站上所示。
