   1.获取密钥

   http://lbsyun.baidu.com/apiconsole/key
   创建应用:–>
   应用名称:BaiduMapTest
   应用类型:Android SDK

   发布版SHA1:A9:7D:70:70:4C:67:83:71:AC:FD:18:6E:EF:9B:08:FF:CF:07:A6:BD
   如何获取:AS–>Build–>Generate Signed APK
   创建签名文件key.jks
   keytool -v -list -keystore key.jks

   SHA1: A9:7D:70:70:4C:67:83:71:AC:FD:18:6E:EF:9B:08:FF:CF:07:A6:BD
   包名:com.bshui.baidumaptest
   提交后生成访问应用AK:HSyrKQAG1BktzbYSqtR8ZQHTPwleEGaV

2.开发包&Demo下载

   最新版本为:Android 地图 SDK v4.5.2
   http://lbsyun.baidu.com/index.php?title=sdk/download&action#selected=mapsdk_basicmap,mapsdk_searchfunction,mapsdk_lbscloudsearch,mapsdk_calculationtool,mapsdk_radar
   在导入时需要根据包名和SHA1生成一个key在BaiduMapsApiASDemo的AndroidMainfest.xml里添加
   运行Demo测试地图功能

   3.Android Studio工程配置

   1)开发包拷到工程
       将BaiduLBS_Android.jar放到app/libs目录下
       右击BaiduLBS_Android.jar Add As Library…加入库
       同步后build.gradle中会出现 implementation files(‘libs/BaiduLBS_Android.jar’)
   2)在libs下新建armeabi目录
   导入:libBaiduMapSDK_base_v4_5_2.so,libBaiduMapSDK_map_v4_5_2.so,liblocSDK7b.so
   在app的build.gradle中说明so为该libs路径
       sourceSets {
           main {
               jniLibs.srcDir ‘libs’
           }
       }
   4.BaiduMapDemo工程开发

一:显示地图
1)在AndroidManifest中添加开发密钥,所需权限

2)添加开发密钥

3)在布局xml文件中添加地图控件

4)在应用程序创建时初始化SDK引用的Context全局变量
SDKInitializer.initialize(getApplicationContext());

 @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main3);        initView();        LocationClient mLocClient;        MyLocationListenner myListener = new MyLocationListenner();        // 开启定位图层        mBaiduMap.setMyLocationEnabled(true);        //定位初始化        mLocClient = new LocationClient(getApplicationContext());//传入全局的context        mLocClient.registerLocationListener(myListener);//注册定位监听函数        LocationClientOption option = new LocationClientOption();        option.setOpenGps(true);        option.setCoorType("bd09ll"); // 设置坐标类型        option.setScanSpan(1000);        mLocClient.setLocOption(option);        mLocClient.start();//启动定位sdk    } private void initView() {        mMapView = (MapView) findViewById(R.id.bmapView);        //获取地图实例        mBaiduMap = mMapView.getMap();        // 开启定位图层，一定不要少了这句，否则对在地图的设置、绘制定位点将无效        mBaiduMap.setMyLocationEnabled(true);        View child = mMapView.getChildAt(1);        if (child != null) {            child.setVisibility(View.INVISIBLE);        }    }

生命周期方法

@Override    protected void onDestroy() {        super.onDestroy();        mMapView.onDestroy();    }    @Override    protected void onResume() {        super.onResume();        mMapView.onResume();    }    @Override    protected void onPause() {        super.onPause();        mMapView.onPause();    }

自定义类MyLocationListenner实现BDLocationListener接口

private class MyLocationListenner implements BDLocationListener{}

重写方法

  public void onReceiveLocation(BDLocation location) {}

 public void onReceiveLocation(BDLocation location) {            // map view 销毁后不在处理新接收的位置            if (location == null || mMapView == null) {                return;            }            mCurrentLat = location.getLatitude();            mCurrentLon = location.getLongitude();            mCurrentAccracy = location.getRadius();            Log.i("tag","lat:"+ mCurrentLat +"\n"+                    "lon:"+ mCurrentLon);            //构造定位数据                       MyLocationData locData = new MyLocationData.Builder()                    .accuracy(location.getRadius())                    // 此处设置开发者获取到的方向信息，顺时针0-360                    .direction(mCurrentDirection).latitude(location.getLatitude())                    .longitude(location.getLongitude()).build();            mBaiduMap.setMyLocationData(locData);                       if (isFirstLoc) {                isFirstLoc = false;                LatLng ll = new LatLng(location.getLatitude(),                        location.getLongitude());                MapStatus.Builder builder = new MapStatus.Builder();                builder.target(ll).zoom(17.0f);                                    mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));            }        }

自定义类继承Application重写onCreate()方法

public class MyApplication extends Application {    @Override    public void onCreate() {        super.onCreate();        SDKInitializer.initialize(this);    }}

最后别忘了在清单文件里配置
