java - Android Studio 3.0 中任务 ':app:processDebugManifest' 执行失败

Question

我是 Java 和 Android 新手。当我申请 RUN PROJECT 时，会显示此消息。因此我需要您帮助解决以下问题。

Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:design:26.0.2] AndroidManifest.xml:28:13-35
is also present at [com.android.support:appcompat-v7:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:26:9-28:38 to override.

这是我的 gradle 文件，我有 SDK 版本 26.0.2 和 28.0.0

它有一个棘手的解决方案。只需在build.gradle中一一注释掉，然后尝试运行即可。然后就可以很容易地理解问题出在哪里。举个例子:

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
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'
}
