android百度地图开发遇到的错误及解决方法

         最近在做公交查询方面的项目，本来公司要求用Google Map的，但是Google Map android的V1版本已经不允许申请Key了，V2可以申请但是必须是谷歌原生Rom,并且手机必须带有 google play service这两点限制了国内大多数手机，所以又重新选择了百度地图。百度地图4.2开发的时候首先申请key不必说了。下面是我项目中出现的报错，以及我找到的解决方法。 我准备把这个项目中所有关于百度地图的报错做成系列，当然如果有各位博友如果有更好的解决办法，欢迎及时指出。

上面的这个报错发生的原因可能有两点：

        第一：你可能在项目中使用了默认的Application,百度地图API没有能够初始化。解决办法是：自定义一个xxxApplication类继承自android.app.Application;然后在xxxApplication中复写onCreate()方法，在onCreate()方法中加上这么一句代码SDKInitializer.initialize(this)。

        第二：就是你可能已经自定义过Application，但是没有在android manifest中声明，声明的方式就是在application标签的属性中加入android:name属性，用name属性关联你定义的Application.
