我正在使用LibGDX和RoboVM制作应用程序，而且我遇到了谷歌移动广告框架的问题。 我到处搜索但没有解决我的错误。
如果我在 robovm.xml 中声明此框架
<frameworkPaths>
<path>libs</path>
</frameworkPaths>
<frameworks>
<framework>UIKit</framework>
<framework>OpenGLES</framework>
<framework>QuartzCore</framework>
<framework>CoreGraphics</framework>
<framework>OpenAL</framework>
<framework>AudioToolbox</framework>
<framework>AVFoundation</framework>
<framework>GoogleMobileAds</framework>
</frameworks>
当我要创建IPA时，它会给我这个错误。
我该如何解决这个问题？
