我的code到了图片附件发送电子邮件：

My code to send email with a image attachment:

public void sendViaEmail(String pAttachmentPath, String pSubjectLine) {
    Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, pSubjectLine);
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, 
            "Screenshot ****************");
    emailIntent.setType("image/jpeg");
    emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile("file://" + pAttachmentPath));
    mActivity.startActivity(emailIntent);
}

或

public void sendViaEmail(File pAttachmentFile, String pSubjectLine) {
    Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, pSubjectLine);
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, 
            "Screenshot ****************");
    emailIntent.setType("image/jpeg");
    emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pAttachmentFile));
    mActivity.startActivity(emailIntent);
}
