我按照这里的指示https://github.com/react-native-community/react-native-maps/blob/master/docs/installation.md在我的react-native项目上使用MapView。我写在我的谷歌MapAPI键的好地方，但代码仍然找不到它。有时这个错误不出现，我的应用程序只是崩溃。
我的react-native版本是0.60.4，所以我只对版本0.59和更高版本进行了修改，但为了验证，我还尝试了其他修改，但没有解决这个问题。
这是安卓系统/app/src/main/安卓系统清单. xml

<uses-permission android:name="android.permission.INTERNET" />

<application
  android:name=".MainApplication"
  android:label="@string/app_name"
  android:icon="@mipmap/ic_launcher"
  android:roundIcon="@mipmap/ic_launcher_round"
  android:allowBackup="false"
  android:theme="@style/AppTheme">
  <activity

  <meta-data

</application>

这是安卓/build.gradle

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.4.1")

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

        google()
        jcenter()
    }
}
/**
 + Project-wide Gradle configuration properties
 */
ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 28
    supportLibVersion = "28.0.0"
    playServicesVersion = "11.8.0" // or set latest version
    androidMapsUtilsVersion = "0.5+"
}

这是我的App.js

import React from 'react'
import {StyleSheet, Text, View, Button} from 'react-native'

//import Main from './screens/Main'
import Navigation from './Navigation/Navigation'

import MapView from 'react-native-maps';

export default class App extends React.Component{

  _loadSports(){

  }
  render () {
    return (
      <View>
        <MapView
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
/>
      </View>
      //<Navigation/>
      )
  }
}

const styles = StyleSheet.create({
  container : {
    flex : 1,
    alignItems : 'center',
    justifyContent:'center',
  }
})

我只是期望解决这个问题：/
