更新到android studio 2.3后,我收到了这个错误消息。我知道这只是一个提示,因为应用程序运行正常,但这真的很奇怪。

所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃)。找到版本25.1.1、24.0.0。示例包括com.android.support:animatedvector-drawable:25.1.1和com.android.com/support:mediarouter-v7:24.0.0

以下是修复此警告的流程

建筑物玻璃

android {
    compileSdkVersion ... // must same version (ex: 26)
    ...
}

dependencies {
    ...
    compile 'any com.android.support... library'  // must same version (ex: 26.0.1)
    compile 'any com.android.support... library'  // must same version (ex: 26.0.1)

    ...
    compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
         // do nothing 
    }

    ...
    compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) { 
        // By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)

        // If you want to use 26.0.1 use
        exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7') 
        exclude group: 'com.android.support', module: 'another module'
        ...

        // If you want to use 27.0.1 do 
        Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
        (It may be a good solution because the best practice is always use latest `compileSdkVersion`.  
        However, use 26 or 27 is base on you for example higher library may have bug)

查看/验证应用程序中所有库的依赖关系打开终端并运行/gradlew应用程序:依存关系

要查看应用程序中特定库的依赖项,请遵循以下教程:-如何在Gradle中排除特定依赖项的依赖项

使用变量:执行以下操作将使您更容易确保对所有库使用相同的版本

dependencies {

    ext {
        support_library_version = '25.2.0'
        google_play_services_version = '10.2.0'
    }

    //#####################################################################
    //          Support Library
    //#####################################################################
    compile "com.android.support:appcompat-v7:${support_library_version}"
    compile "com.android.support:palette-v7:${support_library_version}"
    compile "com.android.support:design:${support_library_version}"

    //#####################################################################
    //          Google Play Services
    //#####################################################################
    compile "com.google.android.gms:play-services-auth:${google_play_services_version}"
    compile "com.google.android.gms:play-services-ads:${google_play_services_version}"
    compile "com.google.android.gms:play-services-analytics:${google_play_services_version}"

    //#####################################################################
    //          Firebase
    //#####################################################################
    compile "com.google.firebase:firebase-core:${google_play_services_version}"
    compile "com.google.firebase:firebase-auth:${google_play_services_version}"
    compile "com.google.firebase:firebase-messaging:${google_play_services_version}"

有关Google建议您如何处理此版本控制的更多信息,请参阅本文:https://developer.android.com/studio/build/index.html#top-水平,水平

对我来说,错误是由于我导入的第三方库使用了较旧的Google Support library模块造成的。我只是将它们更新到最新版本(例如在Github上检查),错误就消失了。我建议检查你的build.gradle中包含的所有非Google库是否是最新的。

我的问题解决了添加以下最新的dependencyimplementation“com.google.firebase:firebaseauth:16.0.4”

解决冲突的另一种方法是强制所有依赖项使用正确的版本,如下所示:

dependencies {
            configurations.all {
                resolutionStrategy.eachDependency { DependencyResolveDetails details ->
                    if (details.requested.group == 'com.android.support' && details.requested.name == 'support-v4') {
                        details.useVersion "27.0.2"
                    }
                }
    ...
    }

所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃)。找到版本25.1.1、24.0.0。示例包括com.android.support:animatedvector-drawable:25.1.1和com.android.com/support:mediarouter-v7:24.0.0

当我们使用Google Play Services时,通常会出现此警告,因为它使用支持库作为依赖项。

我们大多数人都不知道我们可以覆盖Google Play Services中使用的支持库。当我们使用以下依赖项时:

implementation "com.android.support:animated-vector-drawable:25.1.1"

它隐含地依赖于com.android.support:mediarouter-v7:25.1.1。但它与谷歌Play服务的依赖性冲突,后者是com.android.support:mediarouter-v7:24.0.0。因此,我们需要通过显式使用库来重写它:

implementation "com.android.support:mediarouter-v7:25.1.1"

然后,依赖项块将包括这两个项,如下所示:

dependencies {
    implementation "com.android.support:animated-vector-drawable:25.1.1"
    implementation "com.android.support:mediarouter-v7:25.1.1"

    ...
}
