1. 安装依赖

yarn add react-native-amap-geolocation

2.引包使用

import { Platform, PermissionsAndroid } from 'react-native'  
import {init, Geolocation } from 'react-native-amap-geolocation'

async getLocation() {
        if(Platform.OS === 'android') {
            const granted = await PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.ACCESS_COARSE_LOCATION)
            if (granted === PermissionsAndroid.RESULTS.GRANTED) {
                //设置高德key
                await init({
                   // ios: "9bd6c82e77583020a73ef1af59d0c759",
                   android: "7c9050abafa88e8ef98d7232c09ea258"   // 传入AMAP_KEY
                });
                Geolocation.getCurrentPosition(
                    ({location}) => {
                        console.log(location.address)
                        // 输出结果
                         // {

    // 测试高德定位
    componentDidMount() {
        this.getLocation()
    }

3. 申请高度key

发行版的

需在本地cmd中的 C:\Program Files\Java\jdk1.8.0_152\bin中执行 通过

keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

输入密码（123456）自己写的

会生成一个my-release-key.keystore 文件，复制到android/app  （复制到.android目录）

查看命令

keytool -v -list -keystore E:\ReactNative\tanhua\android\app\my-release-key.keystore

结果
