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

当前回答

我有这个:

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:27.1.1'
   implementation 'com.android.support:design:27.1.1'
   implementation 'com.android.support:support-v4:27.1.1'
   implementation 'com.google.firebase:firebase-auth:12.0.1'
   implementation 'com.google.firebase:firebase-firestore:12.0.1'
   implementation 'com.google.firebase:firebase-messaging:12.0.1'
   implementation 'com.google.android.gms:play-services-auth:12.0.1'
   implementation'com.facebook.android:facebook-login:[4,5)'
   implementation 'com.twitter.sdk.android:twitter:3.1.1'
   implementation 'com.github.PhilJay:MPAndroidChart:v3.0.3'
   implementation 'org.jetbrains:annotations-java5:15.0'
   implementation project(':vehiclesapi')
   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'
}

并得到以下错误:

解决方案很简单-主要依赖项都是正确的,因此留下了任何第三方依赖项。一个接一个地删除,直到找到罪魁祸首,结果是facebook!它使用的是27.0.2版本的android支持库。我试图添加cardview 27.1.1版本,但这并不奏效,因为解决方案仍然足够简单。

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:27.1.1'
   implementation 'com.android.support:design:27.1.1'
   implementation 'com.android.support:support-v4:27.1.1'
   implementation 'com.google.firebase:firebase-auth:12.0.1'
   implementation 'com.google.firebase:firebase-firestore:12.0.1'
   implementation 'com.google.firebase:firebase-messaging:12.0.1'
   implementation 'com.google.android.gms:play-services-auth:12.0.1'
   implementation('com.facebook.android:facebook-login:[4,5)'){
       // contains com.android.support:v7:27.0.2, included required com.android.support.*:27.1.1 modules
    exclude group: 'com.android.support'
   }
   implementation 'com.android.support:cardview-v7:27.1.1' // to replace facebook sdk's cardview-v7:27.0.2.
   implementation 'com.twitter.sdk.android:twitter:3.1.1'
   implementation 'com.github.PhilJay:MPAndroidChart:v3.0.3'
   implementation 'org.jetbrains:annotations-java5:15.0'
   implementation project(':vehiclesapi')
   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'
}

其他回答

只需添加以下内容:

compile 'com.android.support:mediarouter-v7:25.2.0'

针对新SDK版本更新

compile 'com.android.support:mediarouter-v7:28.0.0-alpha3'

突出显示错误并按“ALT+ENTER”,您将看到一个选项:

添加库依赖项>编辑意图设置

这会将您带到一个菜单,在那里您将看到与支持兼容不同的特定问题支持依赖关系。在gradle(com'XXX')中创建其依赖项,并将其版本设置为与support-compat的版本匹配。同步渐变,你就完成了。

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"
                    }
                }
    ...
    }

我跑了/gradlew任务--所有任务,并检查与目标版本(25.3.1)不同的依赖项

在本例中,我的目标是25.3.1,并且在运行此命令时有一些针对不同版本的依赖关系。诀窍是在这个列表中识别针对以前版本的依赖项,并通过在Gradle中导入最新版本的依赖关系来覆盖这些依赖项。

如果appcompat上出现相同错误

implementation 'com.android.support:appcompat-v7:27.0.1'

然后添加设计解决了这个问题。

implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'

对我来说

implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'

包括appcompat-v7:23.1.1

.didea/库

没有vlc,仅appcompat就足够了。
