做一个关于百度地图的项目，项目有几个大功能，做第一个功能，需要加载百度地图，加载时稍微有点慢，但是加载后没有任何问题，这个板块做完后 ，做另外的功能后添加了不少activity，这个大功能也做完后，回过头完善第一个功能时，问题来了！
加载完百度地图后，就崩溃，手机黑屏，或者开始没崩溃，点击打开一个子activity，必崩溃。

大神求解释！
------解决思路----------------------
singleton mode
是否要设置成singleton呢
------解决思路----------------------
你的activity有重复启动的吗？
------解决思路----------------------
你把activity 的模式改变一下换成其他的试试，不是有四种启动模式么，你每一个都试试，那么问题来了：
更改模式那家强？
