1.申请key值

https://lbs.amap.com/api/android-sdk/guide/create-project/android-studio-create-project?tdsourcetag=s_pcqq_aiomsg

2.权限

3.引入jar包及相应的配置

4.配置清单文件

5.配置build
android {
compileSdkVersion 28
defaultConfig {
applicationId “com.qgs.gd”
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName “1.0”
testInstrumentationRunner “android.support.test.runner.AndroidJUnitRunner”

    defaultConfig {
        ndk {
            //设置支持的SO库架构（开发者可以根据需要，选择一个或多个平台的so）
            abiFilters "armeabi", "armeabi-v7a", "arm64-v8a", "x86","x86_64"
        }
    }
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

public interface Constant {
String gaode_key = “6ad11ccb906ec62b5b106ae673d9d41c”;
}
