【问题描述】：

我有以下配置 app/build.gradle

 implementation project(':react-native-firebase')
    implementation "com.google.firebase:firebase-auth:11.+"
    implementation "com.google.firebase:firebase-core:11.+"
    implementation "com.google.firebase:firebase-firestore:11.+"
    implementation "com.google.firebase:firebase-database:11.+"
    // implementation "com.google.firebase:firebase-auth:11.+"
    implementation(project(':react-native-maps')) {
        exclude group: 'com.google.android.gms', module: 'play-services-base'
        exclude group: 'com.google.android.gms', module: 'play-services-maps'
    }
    implementation 'com.google.android.gms:play-services-base:11.+'
    implementation 'com.google.android.gms:play-services-maps:11.+'
    implementation 'com.google.android.gms:play-services-location:11.8.0'
    implementation project(':react-native-geolocation-service')
    implementation project(':react-native-background-timer')
    implementation project(':react-native-mauron85-background-geolocation')
    implementation project(':react-native-contacts')
    implementation project(':react-native-gesture-handler')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.facebook.react:react-native:+"  // From node_modules

Package.json

"react": "16.6.3",
    "react-native": "0.58.6",
    "react-native-background-timer": "^2.1.1",
    "react-native-contacts": "^3.1.4",
    "react-native-firebase": "^5.2.3",
    "react-native-geolocation-service": "^2.0.0",
    "react-native-gesture-handler": "^1.1.0",
    "react-native-maps": "^0.23.0",
    "react-native-mauron85-background-geolocation": "^0.5.0",
    "react-native-permissions": "^1.1.1",
    "react-navigation": "^3.3.2"

Android/gradle

classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.1'

当我尝试关注时

https://firebase.google.com/docs/android/setup#available-libraries

出现错误

this.unsubscribe = firebase.firestore().collection('locations').onSnapshot(this.getCollectionData)

应用程序崩溃

请帮忙

谢谢

【问题讨论】：

您提到的 firebase 集成是什么？？
rnfirebase 库
我可以在 firebase 中添加数据，但是使用 onSnapshot 时会抛出错误
您是否遵循此文档rn-firebase ??
是的，这里出错 this.unsubscribe = firebase.firestore().collection('locations').onSnapshot(this.getCollectionData

标签： firebase react-native google-cloud-firestore react-android

【解决方案1】：

我有同样的错误。请创建名为“locations”的集合并添加一个虚拟文档。那就试试吧。
