Android unity 从activity跳转至unityActivity再finish会崩溃

Question

我新建了一个简单的unity工程，导出为简单的不可直接用的android工程。然后新建一个安卓工程，将unity导出的资源一一拷贝进去，然后在mainActivity中跳转至unityActivity，但是每次finish当前unityactivity都会crash掉，下面是我的安卓代码，求大神们帮忙看看这是为什么，感激不尽！

UnityPlayerActivity:

 package com.cain.unitytest.activity;

import com.cain.unitytest.R;
import com.cain.unitytest.inject.ContentView;
import com.cain.unitytest.inject.ViewInject;
import com.unity3d.player.*;

import android.content.res.Configuration;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.Toast;

@SuppressWarnings("unused")
@ContentView(R.layout.activity_unity)
public class UnityPlayerActivity extends BaseActivity {
    private static final String TAG = UnityPlayerActivity.class.getSimpleName();

    protected UnityPlayer mUnityPlayer;     // don't change the name of this variable; referenced from native code

    @ViewInject(R.id.unity_test_view)
    private LinearLayout unityPanel;

    // Setup activity layout
    @Override protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mUnityPlayer = new UnityPlayer(this);

        unityPanel.addView(mUnityPlayer);
    }

    /**

     * @param v 发起组件
     */
    public void changeBackgroundColor(View v) {
        UnityPlayer.UnitySendMessage("AndroidInterface", "ChangeCameraBackground", "#fafafa");
    }

    /**
     * 显示toast,被unity调用
     * @param message toast内容
     */
    public void showToast(final String message) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(UnityPlayerActivity.this, message, Toast.LENGTH_SHORT).show();
            }
        });
    }

    /**

    @Override
    public void onBackPressed() {
        //super.onBackPressed();
        //UnityPlayer.UnitySendMessage("AndroidInterface", "Finish", "");
        //mUnityPlayer.quit();
        finish();
    }

    // Quit Unity
    @Override

        mUnityPlayer.quit();
        super.onDestroy();
    }

    // Pause Unity
    @Override

    }

    // 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);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mUnityPlayer.injectEvent(event);
    }
}

每次crash都是底层的错误，每次都有下面的错误：
启动unity页面时：
