Cannot access android.support.v4.app.*

 解决办法：

添加到受影响的 module build.gradle 中（比如app的gradle文件根代码下）

 configurations.all {
     resolutionStrategy.eachDependency {
         DependencyResolveDetails details ->
             def requested = details.requested
             if (requested.group == 'com.android.support') {
                 if (!requested.name.startsWith("multidex")) {
                     details.useVersion '27.1.1'
                 }
             }
     }
 }
