回答1:

First, add build.gradle file, to include the google-services plugin and the Google's Maven repository:

buildscript {
// ...
dependencies {
    // ...
    classpath 'com.google.gms:google-services:4.0.1' // google-services 
plugin
}
}

 allprojects {
// ...
repositories {
    // ...
    maven {
        url "https://maven.google.com" // Google's Maven repository
    }
}
 }

add the apply plugin line at the bottom of the file to enable the Gradle plugin:

apply plugin: 'com.android.application'

android {
 // ...
 }

 dependencies {
  // ...
 implementation 'com.google.firebase:firebase-core:16.0.0'

  // Getting a "Could not find" error? Make sure you have
  // added the Google maven respository to your root build.gradle
  }

  // ADD THIS AT THE BOTTOM
  apply plugin: 'com.google.gms.google-services'

You should also add the dependencies for the Firebase SDKs you want to use. We recommend starting with com.google.firebase:firebase-core

I have fix problem : import onesignal

buildscript {
    repositories {
        maven { url 'https://plugins.gradle.org/m2/'}
    }
    dependencies {
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:0.10.1'
    }
}
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

repositories {
    maven { url 'https://maven.google.com' }
}

Remove implementation 'com.google.firebase:firebase-core:16.0.0' and useimplementation 'com.google.firebase:firebase-database:10.0.0' for firebase database, it will solve your problem.

回答5:

To fix this issue I followed Google firebase integration guidelines and did the following changes in my app/build.gradle and project/build.gradle

Follow this link if you have any doubts

https://firebase.google.com/docs/android/setup

changes in app/build.gradle

implementation 'com.google.android.gms:play-services-base:15.0.2'
implementation "com.google.firebase:firebase-core:16.0.1"
implementation "com.google.firebase:firebase-messaging:17.4.0"

Changes in Project/build.gradle

repositories {

        google()
        jcenter()
        mavenCentral()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath 'com.google.gms:google-services:4.2.0'// // google-services plugin it should be latest if you are using firebase version 16.0 +
       
    }
    allprojects {
    repositories {
         google()// add it to top instead of bottom or somewhere in middle
        mavenLocal()
        mavenCentral()
        maven {
            url 'https://maven.google.com'
        }
       
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        
    }
}
