ionic打包apk报错问题A problem occurred configuring root project 'android'.

今天打包ionic项目的时候报出了下面错误：

What went wrong: A problem occurred configuring root project 'android'. > Could not resolve all dependencies for configuration ':_debugCompile'. > Could not find any version that matches com.android.support:support-v4:24.1.1+. Searched in the following locations: https://repo1.maven.org/maven2/com/android/support/support-v4/maven-metadata.xml https://repo1.maven.org/maven2/com/android/support/support-v4/ Required by: :android:unspecified * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.错误原因是sdk的包没下载全，主要缺的是下面的几个文件，通过sdk manager下载；

下载完成之后，运行“ionic build android”命令
