我有以下Android Unity 3D项目文件，它在运行时使用java.lang.RuntimeException编译但失败：无法启动活动ComponentInfo java.lang.nullpointerexception。 runtime error message

这是UnityPlayerNavtiveActivity.java 

  package com.sniper.game;

  import com.unity3d.player.*;
  import android.app.NativeActivity;
  import android.content.res.Configuration;
  import android.graphics.PixelFormat;
  import android.os.Bundle;
  import android.view.KeyEvent;
  import android.view.MotionEvent;
  import android.view.View;
  import android.view.Window;
  import android.view.WindowManager;

  public class UnityPlayerNativeActivity extends NativeActivity
 {
 protected UnityPlayer mUnityPlayer;        // don't change the name of this variable; referenced from native code

// Setup activity layout
@Override protected void onCreate (Bundle savedInstanceState)
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);

    getWindow().takeSurface(null);
    setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
    getWindow().setFormat(PixelFormat.RGBX_8888); // <--- This makes xperia play happy

    mUnityPlayer = new UnityPlayer(this);
    if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true))
        getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,
                               WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(mUnityPlayer);
    mUnityPlayer.requestFocus();
}

// Quit Unity
@Override protected void onDestroy ()
{
    mUnityPlayer.quit();
    super.onDestroy();
}

// Pause Unity
@Override protected void onPause()
{
    super.onPause();
    mUnityPlayer.pause();
}

// Resume Unity
@Override protected void onResume()
{
    super.onResume();
    mUnityPlayer.resume();
}

// This ensures the layout will be correct.
@Override public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    mUnityPlayer.configurationChanged(newConfig);
}

// Notify Unity of the focus change.
@Override public void onWindowFocusChanged(boolean hasFocus)
{
    super.onWindowFocusChanged(hasFocus);
    mUnityPlayer.windowFocusChanged(hasFocus);
}

// For some reason the multiple keyevent type is not supported by the ndk.
// Force event injection by overriding dispatchKeyEvent().
@Override public boolean dispatchKeyEvent(KeyEvent event)
{
    if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
        return mUnityPlayer.injectEvent(event);
    return super.dispatchKeyEvent(event);
}

// Pass any events not handled by (unfocused) views straight to UnityPlayer
@Override public boolean onKeyUp(int keyCode, KeyEvent event)     { return mUnityPlayer.injectEvent(event); }
@Override public boolean onKeyDown(int keyCode, KeyEvent event)   { return mUnityPlayer.injectEvent(event); }
@Override public boolean onTouchEvent(MotionEvent event)          { return mUnityPlayer.injectEvent(event); }
/*API12*/ public boolean onGenericMotionEvent(MotionEvent event)  {      return mUnityPlayer.injectEvent(event); }
}

这是UnityPlayerActivity.java：

    package com.sniper.game;

    import com.unity3d.player.*;

 /**
 * @deprecated Use UnityPlayerNativeActivity instead.
 */
  public class UnityPlayerActivity extends UnityPlayerNativeActivity { }

这是UnityPlayerProxyActivity.java：

package com.sniper.game;

import com.unity3d.player.*;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

/**
 * @deprecated Use UnityPlayerNativeActivity instead.
*/
public class UnityPlayerProxyActivity extends Activity
{
protected void onCreate (Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    Intent intent = new Intent(this,   com.sniper.game.UnityPlayerNativeActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    Bundle extras = getIntent().getExtras();
    if (extras != null)
        intent.putExtras(extras);
    startActivity(intent);
    }
}

这是AndroidManifest.xml：

以下是几小时后从上面的屏幕截图中发现的完整日志跟踪：

我需要帮助让这个Unity3D Android游戏在模拟器上运行，然后下载并在实际设备上运行。
