解决方法如下，在你的app下的build.gradle文件中加上

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

    configurations.all {
        resolutionStrategy {
            eachDependency { details ->
                // Force all of the primary support libraries to use the same version.
                if (details.requested.group == 'com.android.support') {
                    if (!requested.name.startsWith("multidex")) {
                        details.useVersion '28.0.0'
                    }
                }
            }
        }
    }

}
