本文探讨了在使用百度地图SDK时遇到的初始化错误问题，特别是在模拟器环境下。文章详细分析了错误原因，并提供了检查初始化状态、确保正确引用so包及配置gradle等解决方案。

今天突然出现了一个错误，也是因为我使用模拟器之后的错误，百度地图在使用模拟器初始化会出错，百度他本身不支持google的模拟器，所以我就把 SDKInitializer.initialize(getApplicationContext());给注释了，然后就出现下面的问题了

初始化百度自定义的 MapView出现发下错误

mMapView = new MapView(mActivity)

java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method ‘java.io.File android.content.Context.getFilesDir()’ on a null object reference
com.baidu.mapapi.map.MapView.(Unknown Source:17)

出现的这些错误都是和百度核心有关，他只是重写 ViewGroup 可他里面引用了很多其他mapsdk函数。所以要解决这些问题就可以出现下面的解决方法了

查看百度初始化成功了吗？（SDKInitializer.initialize(getApplicationContext());）
查看 so包有添加相对应的包了吗？（so包要和jar包对应版本）
查看 gradle有引用so包配置吗？（ jniLibs.srcDirs = [‘src/main/libs’] 或者
jniLibs.srcDir [‘libs’] ）
