在android stdio中使用邮件,激活和其他jar文件时出现I/O错误

Question

我在我的应用程序中使用邮件,激活和其他jar文件以编程方式发送电子邮件.实现这一目标的代码之前运行良好,但最近它只是停止工作.尝试从我的应用程序发送邮件时,我收到以下I/O错误:

我的应用程序中的libs目录中有jar文件,我在gradle文件中使用以下内容来使用jar : compile fileTree(dir: 'libs', include: ['*.jar']).

正如我所说,这一直都很完美,但由于某种原因,它只是开始抛出这些错误.

我删除并重新安装了Android Studio.我还清理了项目,重新启动了IDE并重建了几次项目.我试图将JAR文件添加为模块而不是直接使用libs文件夹.代码中没有错误,因此IDE正在检测JAR文件,但就好像我运行项目后文件丢失一样(不确定发生了什么:()).

你能帮我弄清楚问题是什么以及如何解决？

(要么)

2-我是否可以使用任何替代方法在Android中以编程方式发送不需要使用JAR文件的电子邮件？

如果您需要任何其他信息,请告诉我.先感谢您 :)
