Android attach image to email doesn't work

Question

I'm trying to send email from my application with it's logo.
But I receive the email when the attachment in string format(should be png).
My code:

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("application/image");

    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, getString(R.string.fb_share_description));
    intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://my.package/" + R.drawable.ic_launcher));
   Intent chooser = Intent.createChooser(intent, "share");
   startActivity(chooser);

What should I do?

Answer 1

You cannot attach files to an email from your internal resources. You must copy it to a commonly accessible area of the storage like the SD Card first.

InputStream in = null;
OutputStream out = null;
try {
    in = getResources().openRawResource(R.drawable.ic_launcher);
    out = new FileOutputStream(new File(Environment.getExternalStorageDirectory(), "image.png"));
    copyFile(in, out);
    in.close();
    in = null;
    out.flush();
    out.close();
    out = null;
} catch (Exception e) {
    Log.e("tag", e.getMessage());
    e.printStackTrace();
}


private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while ((read = in.read(buffer)) != -1) {
        out.write(buffer, 0, read);
    }
}

//Send the file
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/html");
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "File attached");
Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "image.png"));
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

This is required as the resources you bundle with your app are read only and sandboxed to your application. The URI that the email client receives is one it cannot access.
