所以我最近刚刚更新到ADT 20，这是一场彻头彻尾的噩梦。
我尝试了我在网上找到的所有解决方案。 1.我将jar放入LIBS文件夹 2.在构建路径＆amp;中添加了来自libary选项卡的jar。在导出路径中检查它 3.我甚至做过这样的事情，有人说将libs文件夹设为源文件夹（我猜它会被导出）
没有任何作用。请帮助这是一场彻头彻尾的噩梦。我根本不能使用任何外部罐子......

答案 0 :(得分：0)
当我发布这个时，我确实弄清楚出了什么问题。 Caused by: com.google.ads.internal.b: Required XML attribute "adUnitId" missing。如此愚蠢，错误日志将它一直放在最底层。
