实验_百度定位

累死哥了。。早饭没吃，现在都晚上八点了晚饭还没吃呢。

运行效果图：

项目框架图：

根据上图完善项目libs文件夹里so与jar文件。

新建DemoApplication.java：

package cn.example.d8_baidumap3;

import android.app.Application;

import com.baidu.mapapi.SDKInitializer;

public class DemoApplication extends Application {

	@Override
	public void onCreate() {
		super.onCreate();
		SDKInitializer.initialize(this);
	}

}

LocationDemo.java代码：

package cn.example.d8_baidumap3;

import android.app.Activity;
import android.os.Bundle;
import android.widget.RadioGroup.OnCheckedChangeListener;

import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.mapapi.map.BaiduMap;
import com.baidu.mapapi.map.BitmapDescriptor;
import com.baidu.mapapi.map.MapStatusUpdate;
import com.baidu.mapapi.map.MapStatusUpdateFactory;
import com.baidu.mapapi.map.MapView;
import com.baidu.mapapi.map.MyLocationData;
import com.baidu.mapapi.model.LatLng;

.xml的代码：

BaidumapSDK3.0之后需要修改 AndroidMainfest.xml代码：添加meta-data，service，supports-screens以及权限：
