新建一个空活动项目
选择语言、平台,修改命名等
ArcGIS SDK
build.gradle (Project: <project name>)
添加
maven {
url 'https://esri.jfrog.io/artifactory/arcgis'
}
build.gradle (Module: <module name>)
添加
implementation 'com.esri.arcgisruntime:arcgis-android:100.10.0'
Gradle
更新:Sync Project with Gradle Files
AndroidManifest.xml
添加
//网络权限
<uses-permission android:name="android.permission.INTERNET" />
//use a MapView (2D) require at least OpenGL ES 2.x:
<uses-feature android:glEsVersion="0x00020000" android:required="true" />
在appdbuild.gradle(Module:app)
的android部分指定Java版本
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
MapView
地图控件修改activity_main.xml
,替换TextView
<com.esri.arcgisruntime.mapping.view.MapView
android:id="@+id/mapView"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
tools:ignore="MissingConstraints">
</com.esri.arcgisruntime.mapping.view.MapView>
定义相关变量
