Android千好万好，唯独模拟器不是太好，在不更换旧有硬件的前提下，使用Android模拟器通常会遭遇效率问题，况且在logcat下面调试，也始终不如开发桌面游戏时那么直观。有没有什么办法，能够解决这一问题呢？

 

其实很容易做到。

 

Android首先是一个精简的Linux平台，其次才是一个手机系统，Java在PC上可以做到的事情，Android不但可以做到，而且能以近乎一致的手段做到。事实上，如果有人故意通过封装抹杀Android与PC上Java应用差异性的话，任何Java游戏，都可以在很少更改代码（或者完全不更改代码）的情况下移植到Android之上。

 

比如，笔者下面提供的这个拼图游戏示例，就可以在几乎不改变程序结构（部分相关类需要替换，不过可以利用正则自动完成）的前提下，运行在Android上。

Android游戏与Java桌面游戏在本质上不存在任何区别，逻辑实现更可以完全一致。通过示例我们看到，把一个以LGame-Simple框架开发的Java桌面游戏移植到Android上居然是如此简单。

 

事实上，未来的Android版LGame-Simple，函数实现将与PC版保持一致，对于差异性代码，笔者也将提供相互转换的辅助工具。

 

如果您正在以LGame-Simple开发Java游戏，那么恭喜您，至多到今年12月底，它也将可以同时运行在Android上了。
