Android ArcGis runtime 100 基础操作
1.为什么升级100.0
我之前在公司做地图一直用的是arcgis10.2，经过多年的开发，这个版本的工具类封装的非常方便，自己也没有时间去换100.0的版本。但是突然有一天工程反馈说他的9.0的安卓手机打开地图直接崩溃，在网上找了半天没有解决arcgis10在9.0手机上的兼容问题，所以只好去换最先的100.0了。但是100.0与10.0的api完全不同，在开发中踩了许多坑，所以了这篇文章希望能帮到之后遇到同样问题的同学。
下面代码如果有错误请大神指出，我会及时改正
2.集成ArcGIS Runtime SDK
集成方式在官方文档中有介绍
1.首先要在build.gradle文件中添加Esri的仓库
allprojects {
repositories {
google()
jcenter()
maven {
url 'https://esri.bintray.com/arcgis'
}
}
}2.第二步添加依赖
dependencies {
implementation 'com.esri.arcgisruntime:arcgis-android:100.4.0'
}3.根据官方文档要求在app模块build.gradle文件中添加如下代码设置java兼容版本
android {
[...]
module.
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}4.最后一步添加权限

4.几个注意点
1.100.0之后没有设置初始化范围的方法（setExtent()）了，想要初始化范围需要利用中心点和比例尺来确定范围。
arcGISMap.setInitialViewpoint()
2.测量面积时，如果点的方向是逆时针的话，会出现负数。所以我们要加个判断，如果是负数需要
GeometryEngine.simplify()方法处理一下。
overallArea = GeometryEngine.area(polygon);
if (overallArea < 0) {
polygon = (Polygon) GeometryEngine.simplify(polygon);
overallArea = GeometryEngine.area(polygon);
}
