Embedding image in email in Android

Question

Is it possible to programatically embed an image in the body of an email sent by the Mail app in Android?

Can I use the ACTION_SEND intent to do this, or should I compose the email myself?

Answer 1

to put the image in the body, you need to set the content type to "text/html" and then put an img tag in the email body. if you don't want to use a webserver to host the image, then you can use a data uri for the image.

Info & Sample:

<img src="data:image/png;base64,
iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABGdBTUEAALGP

If you want to attach an image to the email, you use the putExtra method and set it to EXTRA_STREAM.

emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, myImageStream);

Answer 2

If your image (or file) is in the SD card, you can proceed as follow:

Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/your_path_in_the_sd_card/your_image.png"));
startActivity(shareIntent);

If you don't want to send image, you need to modify the MIME in the "setType()" method.
