Question

我为我的应用程序使用react-native和firebase / firestore。当开发一切正常时，但是当我收集android的发行版时，在应用程序启动时崩溃。出现错误。该应用程序在启动后立即关闭...

当我添加以下行时会发生这种情况：

import * as Firebase from 'firebase';

我没有为Android开发应用程序的经验，我很难理解自己错过或做错了什么。

我的build.gradle：

buildscript {
ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 27
    supportLibVersion = "28.0.0"
}
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'

    classpath 'com.google.gms:google-services:4.2.0' 
}
}

allprojects {
repositories {
    mavenLocal()
    google()
    jcenter()
    maven {
        url "$rootDir/../node_modules/react-native/android"
    }
}
}

task wrapper(type: Wrapper) {
    gradleVersion = '4.7'
    distributionUrl = distributionUrl.replace("bin", "all")
}

我的app / build.gradle

我一直为此苦苦挣扎。让我省钱的是添加了import '@firebase/database'名称空间。您将必须npm install才能保持联系。这是我的完整代码段：

import firebase from '@firebase/app'
import '@firebase/database'
import '@firebase/auth'

运行发行版时React-native + Firebase崩溃
