我正在使用 gmailsender 在我的应用程序中发送电子邮件。我按照下面的链接在 Android 中使用 JavaMail API 发送电子邮件，而不使用默认/内置应用程序

然而，我注意到，每当我使用 proguard 构建我的 APK 时，gmail 发件人都不起作用（当我安装该 APK 时）。没有抛出错误，但没有发送电子邮件。如果我禁用 proguard 然后生成 APK，那么使用该 APK 可以正常工作。

谁能建议这里可能有什么问题。

:::EDIT:::-在生成 APK 时从控制台添加了一些错误消息（删节）行。但是，我可以通过在 PROGUARD CONFIG 文件中忽略它们来摆脱这些警告

最后通过将 proguard 的最新版本从 4.7 更新到 4.9 解决了这个问题。

还将以下内容添加到 proguard 配置文件中

-dontwarn java.awt.**
-dontwarn java.beans.Beans
-dontwarn javax.security.**
-keep class javamail.** {*;}
-keep class javax.mail.** {*;}
-keep class javax.activation.** {*;}
-keep class com.sun.mail.dsn.** {*;}
-keep class com.sun.mail.handlers.** {*;}
-keep class com.sun.mail.smtp.** {*;}
-keep class com.sun.mail.util.** {*;}
-keep class mailcap.** {*;}
-keep class mimetypes.** {*;}
-keep class myjava.awt.datatransfer.** {*;}
-keep class org.apache.harmony.awt.** {*;}
-keep class org.apache.harmony.misc.** {*;}
