java - 添加 firebase 与 google play 服务冲突

问题描述

自从将 Firebase 添加到我的应用程序以便我可以通过 appcenter 向用户发送推送通知以来，我遇到了许多问题。

我目前遇到两个库之间可能的合并问题。

Failed to notify dependency resolution listener.
The library com.google.android.gms:play-services-basement is being 
requested by various other libraries at [[15.0.1,15.0.1]], but 
resolves to 16.0.1. Disable the plugin and check your dependencies 
tree using ./gradlew :app:dependencies.

正如你在这里看到的，我对 play-services-basement 没有任何特定的依赖项......

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'io.realm:realm-gradle-plugin:5.3.1'
    }
}

apply plugin: 'io.fabric'

    syncEnabled = true

}

我已经运行了命令 ./gradlew :app:dependencies 并打印出：

* What went wrong:
Project 'app' not found in root project 'ChimePassportAndroid'.

解决方案

为了使用 Firebase 消息传递，您需要在build.gradle文件中添加相应的依赖项，如下所示：

implementation 'com.google.firebase:firebase-messaging:17.3.4'

你的问题将得到解决。
