        compile 'com.itextpdf:itextg:5.5.10'
        testCompile 'junit:junit:4.12'
    }

Answer 1

当您使用不同版本的 SDK 和支持库时，通常会发生这种情况。替换这些

的版本

compile 'com.android.support:cardview-v7:26.0.0-alpha1'
compile 'com.android.support:design:26.0.0-alpha1'

至

compile 'com.android.support:cardview-v7:27.1.0'
compile 'com.android.support:design:27.1.0'

它应该可以工作。
