java.lang.NoClassDefFoundError : ayc for InterstitialAd 错误

Question

如果发现使用旧设备(2.3.6)的用户向我发送此未捕获的异常:

java.lang.NoClassDefFoundError: ayc

错误行的代码是这样的:

mInterstitialAd = new InterstitialAd(this);
//... some defenitions
AdRequest adRequest = new AdRequest.Builder().build();
mInterstitialAd.loadAd(adRequest);/// <<< THE ERROR APPEARS

是否可以在不包装 try-(catch Exception e)-finally 的情况下修复此错误？

Answer 1

这是一个 SDK 问题，而不是您的代码有问题。

刚刚推出的 Play 服务版本包含一个影响运行 Gingerbread 的设备的移动广告错误。工程人员意识到了这一点，已创建修复程序，并将在下一个版本中发布。
