在日食中我应该怎么处理这个问题呢？（对不起我写英文不是很神）

并且声明这个例子。 （我的项目名称是“第一个”）

感谢。

Answer 1

在项目属性中设置如下所示的api-level 21.

for Android studio在build.gradle

中设置如下

android {
  compileSdkVersion 21
  // ...

  defaultConfig {
    // ...
    targetSdkVersion 21
  }
}

Answer 2

在eclipse中打开你的project.properties文件（appcompat lib）并将目标编辑为android-21或以上警告你不应该手动使用属性来改变它。
