一切，我尝试同步摇篮这个错误出现。我使用SDK的21岁，我已经安装了所有的更新。我试图删除Value.xml，清洁的摇篮，同步并试图改变SDK版本。仍然是上来了。

解决方案

您需要确保所有的模块都支持库的依赖也已编译的SDK设置为21，所以还是项目结构并检查所有的模块上的左手侧。

Everything i try to sync Gradle this error comes up. I am using SDK 21 and I have all updates installed. I tried deleting the Value.xml, cleaning the Gradle, syncing it and trying to change the SDK version. and still it come up.

here is what goes wrong

If you would like the project to see give me a message. Im really new to android studio. Ive rebuild the app also.

解决方案

You need to make sure all your modules that have the support library as dependency also have the compile SDK set to 21. So go to Project Structure and check all the modules on the left hand side.
