compile 'com.google.android.gms:play-services:5.0.77'
在我的gradle。 我已输入此处指定的所有部件;
https://developers.google.com/mobile-ads-sdk/docs/
但仍然没有。 希望有人能帮忙..！
干杯
activity_main.xml中
AndroidManifest.xml中
build.gradle（依赖项）
dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.google.android.gms:play-services:5.0.77' }
我在尝试预览自定义视图AdView时遇到了同样的问题。 我的项目是使用gradle通过Intellij社区版（13.x）构建的，我最终更改了Google Play服务的版本
compile 'com.google.android.gms:play-services:5.+'
至
compile 'com.google.android.gms:play-services:4.+'
具体来说，我将gradle文件的依赖项部分更改为如下所示：
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.google.android.gms:play-services:4.+' }
我遇到了同样的问题，我更换了compile 'com.google.android.gms:play-services: +'来compile 'com.google.android.gms: play-services: 4.4.52 +'
