当我使用最新且相同的版本时，为什么 Gradle 会给出有关依赖项的错误？今天才刚刚开始，我不知道如何解决这个问题:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:26.1.0

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:animated-vector-drawable-v7:28.0.0'
    implementation 'com.android.support:support-media-compat-v7:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
}

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not generate a proxy class for class com.android.build.gradle.tasks.BuildArtifactReportTask.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

最佳答案

也许这是因为支持库版本 28 没有任何调用它的库

implementation 'com.android.support:animated-vector-drawable-v7:28.0.0'

或

implementation 'com.android.support:support-media-compat-v7:28.0.0'

或者这可能是因为您使用的是支持库版本 28，但 targetSdkVersion 低于版本 28。

(在 Android Studio v:3.1.4 中)如果您想将另一个库添加到您的项目中，请使用以下 URL

(from toolbar) file \ Project Structure ... \ (from left window : under modules) app \ Dependencies \ (use green plus)

这对我有用:在 build.gradle (Project Gradle) 中添加这一行

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "your project"
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    buildToolsVersion '28.0.3'
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'junit:junit:4.12'
    implementation 'com.android.support:support-v13:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support.test.espresso:espresso-contrib:3.0.2'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:mediarouter-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support:support-annotations:28.0.0'

关于android - 依赖项是最新的，但 Gradle 认为不是，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52571014/
