如何将SD卡中的图像附加到电子邮件？

Question

I am trying to attach an image from SD Card to an email (from my app to Gmail app).

Every time I try, I select Gmail app and it closes, it doesn't attach the file.

Let's say the image path is: /sdcard/DCIM/Snapseed/Snapseed4.jpg . This is the code I am using to send the email:

Intent emailintent2 = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
emailintent2.setType("image/*");
emailintent2.putExtra(Intent.EXTRA_EMAIL, emailaddress2);
emailintent2.putExtra(Intent.EXTRA_SUBJECT, CorAsunto);
emailintent2.putExtra(Intent.EXTRA_TEXT, message2);

Uri uris = Uri.fromFile(new File(Environment.getExternalStorageDirectory()
        + "/DCIM/Snapseed/Snapseed4.jpg"));

emailintent2.putExtra(Intent.EXTRA_STREAM, uris);
startActivity(emailintent2);

Answer 1

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setType("text/plain");
    emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    emailIntent.setType("image/jpeg");
    emailIntent.putExtra(Intent.EXTRA_STREAM,Uri.parse("SDCARD IMAGE PATH"));
    startActivity(Intent.createChooser(emailIntent,"Share image using"));
