Android服务,JavaMail API

Android服务,JavaMail API,java,android,email,logcat,Java,Android,Email,Logcat,我有一段代码在工作。但当我尝试运行时,会显示错误异常。 我使用广播接收器在每次重新启动时启动服务,服务监视器sim卡更改并向用户生成电子邮件。但我在编译时遇到问题,LogCat显示以下内容: LogCat 01-24 17:00:14.035: E/SimSerial::(8538): 8944110065486249080 01-24 17:00:14.035: E/Current Sim Serial::(8538): 8944110065486249080 01-24 17:00:14.0
