Question

我使用android studio，经过2天的搜索我无法解决这个问题，我想在我的项目中使用AdView我尝试了很多东西但我仍然有这个错误在Android工作室的设计时间。

目前build.gradle文件有

android {       compileSdkVersion 21       buildToolsVersion＆＃34; 21.1.2＆＃34;       ....}

依赖{       编译fileTree（dir：＆＃39; libs＆＃39;，include：[＆＃39; * .jar＆＃39;]）       编译com.google.android.gms：play-services-ads：6.5.87＆＃39;    }
