android - 支持库必须使用 compileSdkVersion 28 的确切版本规范错误

Question

将 compileSdkVersion 从 27 更新到 28 并将支持库从 27.1.1 更新到 28.0.0 后，我在 Android Studio 3.2 中收到了这条警告消息:

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-v4:26.1.0

我的 Gradle :

dependencies {
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    // Für Google "Mobile Vision" API
    implementation 'com.google.android.gms:play-services-vision:15.0.2'

    // wird nicht weiterentwickelt
    implementation 'com.edwardvanraak:MaterialBarcodeScanner:0.0.6-ALPHA'

    // für Butter Knife
    // https://github.com/JakeWharton/butterknife
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
    implementation 'com.jakewharton:butterknife:8.8.1'

    // Logging nur im Debug Modus
    // https://github.com/JakeWharton/timber
    implementation 'com.jakewharton.timber:timber:4.7.1'

    // Für Material Dialogs
    // https://github.com/afollestad/material-dialogs
    implementation 'com.afollestad.material-dialogs:core:0.9.6.0'

    // Google support library
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:animated-vector-drawable:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:support-media-compat:28.0.0'

    implementation 'commons-io:commons-io:2.6'
    implementation 'com.google.code.gson:gson:2.8.2'


    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'
}

如果我运行该应用程序，我会在 setContentView(R.layout.activity_main); 行中收到此错误

Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;

2018-09-26 15:03:49.987 21534-21534/com.timeshuttle.lagerapp I/zygote64:     

我该如何继续解决这个问题？

当我添加行时

implementation 'com.android.support:support-v4:28.0.0' 

警告消失，但应用仍然无法启动(同样的错误信息)

更新

当我恢复到 27.1.1 时，版本冲突警告没有出现。该警告仅出现在 28.0.0 中。我应该重新排序依赖项吗？

Answer 1

您的一些依赖项仍在使用 com.android.support:support-v4:26.1.0，因此您需要更新依赖项或使用旧的支持库版本。
