# 一，***配置*** #

### 1.在buile.gradle(Module.app) ###

android里面加入

packagingOptions {
        exclude 'META-INF/LGPL2.1'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }

在dependencies里加入

//添加Runtime依赖
    implementation 'com.esri.arcgisruntime:arcgis-android:100.3.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])

### 2.在buile.gradle（Project） ###

加入

allprojects {
        repositories {
            google()
            jcenter()
    
            // Add the Esri public Bintray Maven repository
            maven {
                url 'https://esri.bintray.com/arcgis'
            }
        }
    }

### 3.在AndroidManifest.xml 添加相关权限 ###

<uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
     <uses-feature
            android:glEsVersion="0x00020000"
            android:required="true" />

**完成以上步骤arcgis配置 就OK了；**

### 然后创建一个Activity ###

package com.example.text;
    import android.graphics.Color;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import com.esri.arcgisruntime.geometry.Point;

    public class MapViewActivity extends AppCompatActivity {
        private MapView mMapView;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_map_view);
           mMapView = (MapView)findViewById(R.id.mapView);
    
    //创建并添加地图服务*********************************

         /* 英文地图   ArcGISMap map = new ArcGISMap(Basemap.Type.TOPOGRAPHIC, 32.344914, 114.740954, 16);
            mMapView.setMap(map);*/
         //***********************************************
    //创建底图、并设置底图图层
            Basemap basemap = new Basemap();
            basemap.getBaseLayers().add(arcGISTiledMapServiceLayer);
    //设置地图底图
            map.setBasemap(basemap);
    //设置map地图对象在MapView控件中显示
            mMapView.setMap(map);
       //gps采用的gps84坐标系，arcgis采用的是Gcj02所以要进行坐标转换
            double[] point0 = GPSUtil.gps84_To_Gcj02(32.344914,114.740954);
            Viewpoint vp = new Viewpoint(point0[0], point0[1], 2000);
            map.setInitialViewpoint(vp);
            /*double   longitude =114.740954;
            double  latitude = 32.344914;
            Point wgspoint = new Point(longitude, latitude);
            mMapView.addLayer(new ArcGISTiledMapServiceLayer(strMapUrl));
            Point mapPoint = (Point) GeometryEngine.project(wgspoint, SpatialReference.create(4326), mMapView.getSpatialReference());
            Unit mapUnit = mMapView.getSpatialReference().getUnit();
            double zoomWidth = Unit.convertUnits(3, Unit.create(LinearUnit.Code.MILE_US), mapUnit);
            Envelope zoomExtent = new Envelope(mapPoint, zoomWidth, zoomWidth);
            mMapView.setExtent(zoomExtent);*/
            Point point = new Point(point0[1], point0[0], SpatialReferences.getWgs84());
            SimpleMarkerSymbol simpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.Style.CIRCLE, Color.RED, 10);
            Graphic pointGraphic = new Graphic(point, simpleMarkerSymbol);
            GraphicsOverlay graphicsOverlay = new GraphicsOverlay();
            graphicsOverlay.getGraphics().add(pointGraphic);
            mMapView.getGraphicsOverlays().add(graphicsOverlay);
        }
    
     
    }
