Question

我正在使用基於Cordova應用程序的Mobilefirst平台8.0，我已經導出了簽名的APK文件，但無法生成。 我嘗試了android studio以及命令提示符/終端，請在下面的錯誤日志中找到我從android studio gradle build和命令提示符處獲得的錯誤日志。

操作系統：MAC OS Android Studio：2.3+ Cordova：6.5.0 Mobilefirst 8.0

         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.

         You probably need to update the library versions.

Answer 1

最可能的原因是Proguard規則文件配置錯誤。 在此處關注博客，以成功混淆您的Android項目。

Answer 2

嘗試在您的profuard-mfp.txt文件中添加以下行：

-dontwarn okhttp3.internal.**
