几种方式来尝试
- 无效高速缓存/重新启动AS
- 清理项目和重建
- 更新 “谷歌库”,并在Android SDK管理器 “的Android支持库”。
如果不工作,那么如果你想获得的支持库,这是正确的导入:
compile "com.android.support:support-v4:25.3.1"
如果你的编译API不是25,更改版本到最新的与你的编译API。
如果您使用不兼容的版本,Android Studio应该会给您一个黄色警告。只需将鼠标悬停并使用
P/S给出的建议是:请切勿使用com.google.android.gms:play-services
..它很沉重DEX方法计数
gradle这个通常指向确切的错误,你可以检查和后 –
