Java Android Studio与Android SDK相关的多个错误

我让Android Studio开始学习和开发Android应用程序，一开始它工作得非常好。我制作了一个helloworld应用程序，然后androidstudio说我应该如何更新一些androidsdk相关的东西，我让它来做。一旦完成下载更新，一切都停止工作。现在，在尝试构建任何Android项目时都会出现一些错误

下面是一些错误。MusicPlayer只是android项目。此外，这些错误是在创建一个新项目后出现的，该项目只有一个主要活动，没有cod变化。注意：我已经尝试完全重新安装Android SDK

您的项目使用API level 21专有功能，例如

values-v21

中的材质设计样式，但同时该项目仅使用

android sdk windows\platforms\android-20\android.jar

编译，该版本是以前的版本，不知道材质设计

---

要解决这个问题，请将

build.gradle

文件中的

编译dkversion

（可能还有

targetSdkVersion

）设置为21。

values-v21和

-ic:\android sdk-windows\platforms\android-20\android.jar

的组合是致命的。你在build.gradle文件中没有以v21为目标，你只使用了20。这为我解决了问题，将其作为答案发布，我会检查它。
