android 邮件附件拷贝到应用程序,Android:如何从应用程序发送图像作为电子邮件附件？...-优快云博客

我目前正在尝试创建一个可以拍照的应用,然后将该图片附加到将要转到预先确定的电子邮件地址的电子邮件中.

我有电子邮件工作,我有相机工作.我似乎无法获得相机已添加为附件的图片.我在应用程序中弹出的图像作为一种预览图像,如果这就是为什么它不会附加我没有问题.

发送电子邮件时,已创建图片但已损坏但未打开.好像我正在制作一张不存在的画面.我认为这是将拍摄的照片与创作附件部分联系起来的情况,但我不知道!如果有人可以提供帮助,我将非常感激!

这是我MainActivity与相机一起创建电子邮件的地方:

我希望它简单,我只是不将它们连接在一起.
