我已经给下面

package com.me.myapp; 

import com.unity3d.player.*; 
import android.app.Activity; 
import android.content.res.Configuration; 
import android.os.Bundle; 
import android.view.KeyEvent; 
import android.view.View; 
import android.view.Window; 
import android.view.WindowManager; 

public class myActivity extends Activity 
{ 
    private UnityPlayer mUnityPlayer; 

    // UnityPlayer.init() should be called before attaching the view to a layout. 
    // UnityPlayer.quit() should be the last thing called; it will terminate the process and not return. 
    protected void onCreate (Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 

     requestWindowFeature(Window.FEATURE_NO_TITLE); 

     mUnityPlayer = new UnityPlayer(this); 

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

     int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1); 
     boolean trueColor8888 = false; 
     mUnityPlayer.init(glesMode, trueColor8888); 

     View playerView = mUnityPlayer.getView(); 
     setContentView(playerView); 
     playerView.requestFocus(); 
    } 
    protected void onDestroy() 
    { 
     super.onDestroy(); 
     mUnityPlayer.quit(); 
    } 

    // onPause()/onResume() must be sent to UnityPlayer to enable pause and resource recreation on resume. 
    protected void onPause() 
    { 
     super.onPause(); 
     mUnityPlayer.pause(); 
     if (isFinishing()) 
      mUnityPlayer.quit(); 
    } 
    protected void onResume() 
    { 
     super.onResume(); 
     mUnityPlayer.resume(); 
    } 
    public void onConfigurationChanged(Configuration newConfig) 
    { 
     super.onConfigurationChanged(newConfig); 
     mUnityPlayer.configurationChanged(newConfig); 
    } 
    public void onWindowFocusChanged(boolean hasFocus) 
    { 
     super.onWindowFocusChanged(hasFocus); 
     mUnityPlayer.windowFocusChanged(hasFocus); 
    } 

    // Pass any keys not handled by (unfocused) views straight to UnityPlayer 
    public boolean onKeyMultiple(int keyCode, int count, KeyEvent event) 
    { 
     return mUnityPlayer.onKeyMultiple(keyCode, count, event); 
    } 
    public boolean onKeyDown(int keyCode, KeyEvent event) 
    { 
     return mUnityPlayer.onKeyDown(keyCode, event); 
    } 
    public boolean onKeyUp(int keyCode, KeyEvent event) 
    { 
     return mUnityPlayer.onKeyUp(keyCode, event); 
    } 
} 

游戏崩溃我的活动类线

mUnityPlayer.init（glesMode，trueColor8888）;

任何人都可以帮助解决这个问题。提前致谢。

编辑：我的应用程序坠毁在延长UnityPlayerActivity，而不是myActivity活动与下列崩溃报告

Answer 1

这是你的统一版本的问题。它在统一4.1上崩溃。尝试运行它在统一4.2或3.5，它会运行良好。

Answer 2

我认为你需要从UnityPlayerActivity而不是活动拓展业务，为您使用UnityPlayer。
