这个问题,可以通过注释掉module的gradle中的androidTestCompile部分代码即可。 
第三步:然后又爆出这个问题,问题已经好转,报错信息越来越少了哈哈 
Error:(15, 21) No resource found that matches the given name: attr ‘android:keyboardNavigationCluster’. 
通过下面这个链接的一个回答解决了,stackoverflow可能打不开,下面我介绍一下:如图就是解决方案

简单说就是修改module的gradle 
1.把compileSdkVersion改26 
2.buildToolsVersion改”26.0.1” 
3.compile ‘com.android.support:appcompat-v7:26.0.1’替换之前的版本 
4.sync后会提示下载更新,完成后问题就解决了。
