Question

我在Android项目中使用的是Android Studio 3.0和我正在尝试添加

'implementation 'com.android.support:recyclerview-v7:28.0.0'

同步后，出现以下错误，但我没有发现问题所在。无法解析配置的所有依赖项

':app:debugRuntimeClasspath'.
Could not determine artifacts for com.android.support:recyclerview-v7:28.0.0
Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/support/recyclerview-v7/28.0.0/recyclerview-v7-28.0.0.aar'.

Answer 1

从build.gradle中删除这些行，然后尝试再次同步，可能是这些行引起了问题。

 androidTestImplementation 'com.android.support.test:runner:1.0.2'
 androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

'实现'com.android.support:recyclerview-v7:28.0.0'给出无法获取资源错误
