百度地图小Demo错误

今天学习使用百度地图进行定位，按照开发指南Hello BaiduMapAndroid SDK来做了一个小demo，创建完毕后能够正常运行，但是按照建议将

注意：在SDK各功能组件使用之前都需要调用

SDKInitializer.initialize(getApplicationContext());，因此我们建议该方法放在Application的初始化方法中

将SDKInitializer.initialize(getApplicationContext());方法放入新建的Applicaiton方法中然后运行就会报错

package com.example.dingweibaiduapi;

import com.baidu.mapapi.SDKInitializer;

import android.app.Application;

public class MapApplication extends Application {

public void onCreate() {
super.onCreate();

//在使用SDK各组件之前初始化context信息，传入ApplicationContext
//注意该方法要再setContentView方法之前实现
SDKInitializer.initialize(getApplicationContext());
}

}

报错提示如下：

解决方法：

在mainfest的application配置文件中加入

android:name="com.example.dingweibaiduapi.MapApplication"

，也好就是你调用application这个方法的类名就可以了
