申请高德地图api
官网地址：lbs.amap.com/
-
控制台创建安卓应用
-
获取本机测试sha1安全码
- 进入C:\Users\admin.android
- 执行
keytool -list -v -keystore debug.keystore - 默认秘钥为:
android
-
打开flutter项目android -> app -> src -> main -> AndroidManifest.xml文件
-
第二行代码package对应名称为packageName
生成keystore秘钥
- 在目的磁盘下创建文件夹用于存放keystore秘钥文件（这里存放在D盘下）
- 命令窗口执行
keytool -genkey -v -keystore D:\keystore\key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key - 在项目android -> app -> build.gradle添加，对应地址与密码，测试正式可以使用同一个
- 分开使用可访问:www.cnblogs.com/zhireshini/…
- 在keystore文件夹执行
keytool -list -v -keystore key.jks获取发布版sha1码 - 高德地图api key 配置到此完成。
使用flutter 高德地图定位功能
- android -> app -> src -> main ->androidManifest.xml配置
<!--访问网络-->
<uses-permission android:name="android.permission.INTERNET" />
<!--粗略定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!--精确定位-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!--申请调用A-GPS模块-->
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<!--用于获取运营商信息，用于支持提供运营商信息相关的接口-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--用于访问wifi网络信息，wifi信息会用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<!--用于读取手机当前的状态-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--用于写入缓存数据到扩展存储卡-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
- 在application里配置
<!-- 配置ApiKey -->
<meta-data android:name="com.amap.api.v2.apikey" android:value="高德地图api key" />
<!-- 配置定位Service -->
<service android:name="com.amap.api.location.APSService"/>
- 将此代码覆盖main.dart
