React-Native-Maps：地图是空的。仅显示 Google 徽标和标记

Question

我正在使用 react-native-maps，版本是 "react-native-maps": "0.27.1"。

我能够在 2021 年 10 月 1 日星期五 查看地图。

但是，今天（2021 年 10 月 4 日，星期一）我得到带有 Google 徽标和位置标记的空白地图。

我尝试了 troubleshooting 来自 react-native-maps（即 google_maps_api.xml、PROVIDER_GOOGLE) 但它并没有解决问题。

它还提到它可能是 API 密钥问题，但我在该项目首次运行时一直在使用相同的 API 密钥（我也启用了计费).

I did not make any changes to my file nor did I add anything new but the map still fails to load

I have another project with the same version "react-native-maps": "0.27.1" and it seems to be running fine and displays the map.

这是我的代码片段和其他文件：

MapScreen.js:

import React, {Component} from 'react';
import {View, StyleSheet} from 'react-native';
import MapView, {Marker} from 'react-native-maps';

class DeliveryRoute extends Component {
  constructor(props) {
    super(props);
    this.state = {
      region: {
        latitude: parseFloat(5.3302),
        longitude: parseFloat(103.1408),
        latitudeDelta: 0.002,
        longitudeDelta: 0.002,
      },
    };
  }

  renderMap() {
    return (
      <View style={styles.flex}>
        <MapView
          style={styles.map}
          initialRegion={this.state.region}>
          <Marker coordinate={this.state.region} pinColor="red" />
        </MapView>
      </View>
    );
  }

  render() {
    return <>{this.renderMap()}</>;
  }
}

const styles = StyleSheet.create({
  flex: {
    flex: 1,
  },
  map: {
    ...StyleSheet.absoluteFillObject,
  },
});

export default DeliveryRoute;

android\build.gradle:

buildscript {
    ext {
        buildToolsVersion = "29.0.2"
        minSdkVersion = 21
        compileSdkVersion = 29
        targetSdkVersion = 29
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.0.0")

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }

            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

Answer 1

已解决

这确实是 Google Cloud Platform

上的一个 API 问题

Answer 2

检查您是否启用了下面link中的Maps SDK for Android/Maps SDK for IOS。由于 SDK 被禁用，地图未显示。

对于Android:

https://console.cloud.google.com/apis/library/maps-android-backend.googleapis.com?authuser=2&project=robotic-tract-330912&supportedpurview=project

截图供参考：

对于IOS:
