Libgdx Admob Robovm Eclipse构建错误：架构armv7的未定义符号

我正在为github上的robovm libgdx项目集成admob绑定： 根据本文件：

在“使用设备调试”步骤中，我遇到一个错误：

我需要你帮我解决这个问题。谢谢大家!

我又添加了三个框架（MessageUI、SystemConfiguration、CoreTelephony），解决了这个问题——目前我在robovm.xml中的框架如下所示：

<frameworks>
  <framework>UIKit</framework>
  <framework>OpenGLES</framework>
  <framework>QuartzCore</framework>
  <framework>CoreGraphics</framework>
  <framework>OpenAL</framework>
  <framework>AudioToolbox</framework>
  <framework>AVFoundation</framework>
  <framework>MessageUI</framework>
  <framework>SystemConfiguration</framework>
  <framework>CoreTelephony</framework>
</frameworks>

UIKit
打开
石英砂
岩芯图
开放的
音频工具箱
AVF基金会
MessageUI
系统配置
核心电话

请问，如何在Android Studio中添加这些框架？自从我解决这个问题以来，我一直找不到任何下载，但是你不必下载那些框架。这些框架是iOS的系统框架。xml只定义了Xcode项目需要的系统框架。
