使用 EXTRA_STREAM 发送电子邮件 Intent 在 GMail 中崩溃

Question

我正在尝试从我的应用程序发送带有附件的电子邮件。当弹出选择器时，如果我点击 GMail，GMail 就会崩溃；如果我点击我设备的默认电子邮件客户端，它会完美运行。附件是从外置sd中截取的jpeg。
这里是代码：

filelocation = gv.getPath();
                    Intent emailIntent = new Intent(Intent.ACTION_SEND);
                    // set the type to 'email'
                    emailIntent.setType("image/jpeg");
                    String to[] = {"myemailaddress@gmail.com"};
                    emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
                    // the attachment
                    emailIntent.putExtra(Intent.EXTRA_STREAM, filelocation);
                    // the mail subject
                    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                    emailIntent.putExtra(Intent.EXTRA_TEXT, "Body");
                    emailIntent.setType("message/rfc822");
                    startActivity(Intent.createChooser(emailIntent, "Send email using:"));

这里是logcat:

有什么建议吗？每一个帮助将不胜感激！ :)

这一行：

emailIntent.putExtra(Intent.EXTRA_STREAM, filelocation);

需要 URI 才能工作。更改为：

emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(filelocation));
