React-Native-Maps：地图为空。 仅显示 Google 徽标和标记

Question

I am using react-native-maps and the version is "react-native-maps": "0.27.1" .

I was able to view the map on Friday, 1st October 2021 .

However, today ( Monday, 4th October 2021 ) I am getting blank map with Google logo and just the Marker for location.

I tried troubleshooting from the react-native-maps (ie google_maps_api.xml , PROVIDER_GOOGLE ) but it didn't solve the issue.

It also mentioned it could be API KEY issue but I have been using the same API key for this project when it first worked ( I also have billing enabled ).

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.

Here's my code snippet and other files:

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 {

    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

Answer 1

Check whether you have enabled the Maps SDK for Android / Maps SDK for IOS from the below link. Since SDK is disabled the map is not showing.

For Android:

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

Screenshot for reference:

For IOS:

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

Answer 2

SOLVED

It was indeed an API issue on Google Cloud Platform

Answer 3

在 iOS 中将 provider 属性设置为DEFAULT_PROVIDER为我修复

provider={ Platform.OS === 'ios' ? PROVIDER_DEFAULT : PROVIDER_GOOGLE }
