Question

在我的应用程序中，我正在尝试使用gcm服务，但我甚至无法编译gradle。我不断收到消息，说我不知道＆＃39; firebase core＆＃39;虽然我不知道如何安装它。

这是我的顶级gradle文件：

buildscript {
repositories {
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle:2.1.2'
    classpath "io.realm:realm-gradle-plugin:1.1.0"
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

allprojects {
repositories {
    jcenter()
    maven {
        url "https://jitpack.io"
    }

    maven {
        url "https://mint.splunk.com/gradle/"
    }
}
}

这是我的模块级gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'com.google.gms.google-services'


android {

compileSdkVersion 24
buildToolsVersion "24.0.0"
defaultConfig {
    applicationId "roof.android"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 11
    versionName "0.0.4"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

    exclude 'META-INF/NOTIC E.txt'

    exclude 'META-INF/maven/com.fasterxml.jackson.core/jackson-core/pom.properties'
    exclude 'META-INF/maven/com.fasterxml.jackson.core/jackson-core/pom.xml'
}
}

compile fileTree(include: ['*.jar'], dir: 'libs')

Answer 1

在您的模块Gradle文件（通常是app/build.gradle）中，在文件底部添加apply plugin（apply plugin: 'com.google.gms.google-services'）行以启用Gradle插件。

您还应该为Firebase com.google.firebase:firebase-core和com.google.firebase:firebase-messaging SDK添加依赖项：

apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  compile 'com.google.firebase:firebase-core:10.2.1'
  compile 'com.google.firebase:firebase-messaging:10.2.1'
}

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

确保在使用 Firebase 时安装了最新版本的'Google Play服务'和'Google Repository'。

请按照以下步骤安装：

打开Android工作室
转到菜单栏＆gt;工具＆gt; Android＆gt; SDK Manager
点击标签＆gt; SDK工具
检查并安装'Google Play服务'和'Google存储库'
单击“应用”并等待下载

最后，再次同步和构建您的项目。

Answer 2

您想在自己的应用中添加推送通知吗？

使用firebase而不是GCM。它是GCM的增强版。

您需要以下依赖于firebase推送通知。

compile 'com.google.firebase:firebase-messaging:9.0.1'
compile 'com.google.android.gms:play-services-gcm:9.0.1'

Answer 3

如果要添加firebase核心，可以添加 compile 'com.google.firebase:firebase-core:9.0.0' 在模块级gradle文件中的依赖项标记下。

如果您仍无法解决问题，可能需要先更新SDK才能获得Google Play服务第30版和Google Repository第26版。有关详细信息，请参阅here。

Answer 4

我在com.google.firebase:firebase-core:11.8.0上遇到了同样的问题，将google()存储库移到jcenter()上方后，它仍然起作用。

我之间使用的是Build -> Clean Project。

./ build.gradle

buildscript {
    repositories {
        google() // <- now on top!
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.1.1'
    }
}

allprojects {
    repositories {
        google() // <- now on top!
        jcenter()
    }
}

Answer 5

在存储区部分的android / build.gradle中，尝试将 google（）移到 jcenter（）上。

找不到com.google.firebase：firebase-core：9.0.0？
