Question

我正在尝试使用inonic build android构建Android应用，但我遇到以下错误：

running cordova build android
Running command: "c:\Program Files\nodejs\node.exe" c:\xampp\htdocs\discipulado\
discipulado\hooks\after_prepare\010_add_platform_class.js c:/xampp/htdocs/discip
ulado/discipulado
add to body class: platform-android
Running command: c:\xampp\htdocs\discipulado\discipulado\platforms\android\cordo
va\build.bat
[Error: Please install Android target: "android-21".

Hint: Open the SDK manager by running: C:\Users\Thiago\AppData\Local\Android\sdk
\tools\android.BAT
You will require:
1. "SDK Platform" for android-21
2. "Android SDK Platform-tools (latest)
3. "Android SDK Build-tools" (latest)]
ERROR building one of the platforms: Error: c:\xampp\htdocs\discipulado\discipul

我已经安装了Apache Ant，但错误仍然存在。我使用ionic platform remove android删除了Android平台，并添加了ionic platform add android但没有成功。

有什么想法吗？

更新我已经安装了Android Studio和Android SDK Tools。
