我想在我的应用上添加带有 firebase 的通知。 我在 YouTube 上关注了一个视频 (https://www.youtube.com/watch?v=xx7hemn3FY4) 但是当我在我的 flutter 项目中做同样的事情时出现错误:[[15.0.1,15.0.1]] 的各种其他库正在请求库 com.google.android.gms:play-services-basement ，但解析为 11.8.0。禁用插件并使用 ./gradlew :app:dependencies 检查你的依赖树。

如您在评论中看到的，我尝试了几件事。

项目等级:

 buildscript {
    repositories {
        google()
        jcenter()
    }

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'

    classpath 'com.google.gms:google-services:4.0.1'
    //classpath 'com.google.gms:google-services:4.0.0'

}
}

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

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.0"
            }

        }
    }
}

应用分级:

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 27

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.weatherapp"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    //Implementation 'com.google.android.gms:play-services-basement:15.0.1'
    //Implementation 'com.google.firebase:firebase-core:15.0.0'
}

apply plugin: 'com.google.gms.google-services'

但是这些更改都不起作用。你有其他想法吗？

最佳答案

我遇到了类似的问题，在错误消息中它指出

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 11.8.0. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

已解决解决到 11.8.0

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    //Implementation 'com.google.android.gms:play-services-basement:15.0.1'
    //Implementation 'com.google.firebase:firebase-core:15.0.0'

   implementation 'com.google.firebase:firebase-core:11.8.0'.  // <<--- Add this
}

我通过添加行解决了我的问题

implementation 'com.google.firebase:firebase-core:11.8.0'.  // <<--- Add this

另外，如果这不能解决问题，请添加此行；

com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

在同一文件的末尾，如下所示；

...

dependencies {
  ....
}

....

com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

如果它解决了我们的问题，请告诉我。

谢谢!

关于android - 库 com.google.android.gms :play-services-basement is being requested by various other libraries at [[15. 0.1,15.0.1]]，但解析为 11.8.0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51485608/
