首先登录高德地图 控制台
然后选择创建新应用 里面的应用名称和应用类型根据自己的项目填写

然后点击新建之后 选择右上角添加 里面的key名称根据项目名称填写
PackageName 则在AndroidManifest.xml文件里面

接下来如何获取到高德地图的SHA1
在获取SHA1之前需要先把项目进行打包 打包过程中会产生一个****.jks文件
找到你的javaJDK安装路径 然后直接在命令窗口进入该目录，并且进入该目录的bin目录
然后再次执行命令：keytool -list -v -keystore D:\xxxx.jks
C:\Program Files\Java\jdk-11.0.14\bin>keytool -list -v -keystore D:\me\demo1.jks
输入jks的秘钥口令就可以了

获取到SHA1口令之后复制到对应的地方 然后点击提交可以

接下里集成高德地图
首先集成插件 amap_flutter_location 网址 https://pub.dev/packages/amap_flutter_location/versions
image.png
dependencies:
amap_flutter_location: ^3.0.0
接下来配置一下相关信息 在android下的app里面的build.gradle 加上如下代码
implementation('com.amap.api:location:5.2.0')
image.png
然后在android对象里面加入以下代码
image.png
image.png
signingConfigs {
release { //发布版本的签名配置
storeFile file('demo1.jks')
keyAlias "key0"
storePassword "1qaz2wsx"
keyPassword "1qaz2wsx"
}
debug { //调试版本的签名配置
storeFile file('demo1.jks')
keyAlias "key0"
storePassword "1qaz2wsx"
keyPassword "1qaz2wsx"
}
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
debug {
// TODO: Add your own signing config for the release build. // Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
}
接下来在AndroidManifest.xml中配置相关代码
