Here is the working code which you need:

Firstly save image from Drawable to SD Card here is the code:

try{

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.bubble_green);

            //replace "R.drawable.bubble_green" with the image resource you want to share from drawable 

            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            largeIcon.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

            // you can create a new file name "test.jpg" in sdcard folder.
            File f = new File(Environment.getExternalStorageDirectory() + File.separator + "test.jpg");

            f.createNewFile();

            // write the bytes in file
            FileOutputStream fo = new FileOutputStream(f);
            fo.write(bytes.toByteArray());

            // remember close de FileOutput
            fo.close();
        }
        catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

Then get the saved image from SD card and attach in the email intent like this:

        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
        shareIntent.setType("image/jpeg");

        shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Hi"); //set your subject
        shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "How are you"); //set your message

        String imagePath = Environment.getExternalStorageDirectory() + File.separator + "test.jpg";

        File imageFileToShare = new File(imagePath);

        Uri uri = Uri.fromFile(imageFileToShare);

        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);

        startActivity(Intent.createChooser(shareIntent, "Share Image"));

the problem is image is attach but its not viewing and not able to send..i am testing in device samsung edge.lollipop version – Aditya Aug 06 '15 at 08:40
@Roman i tried this code and it is working perfectly in Nexus 9 (Lollipop). Are you setting `` permission in your manifest? – Anand Singh Aug 06 '15 at 08:44
@Roman Ok, check your directory whether you can see "test.jpg" or not? Try to run same code in other device, check whether it is working there? – Anand Singh Aug 06 '15 at 08:50

This is what worked for me perfectly.

            Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
            shareIntent.setType("image/jpeg");

            shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getResources().getString(R.string.share_subject));
            shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getResources().getString(R.string.share_message));

            shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.image_to_share);

            startActivity(Intent.createChooser(shareIntent, "Share Image"));

But I will always recommend to decode a Bitmap from this resource, save it as a File in the storage and then use that file. A more reliable way this directly using from the resources.

roman thing is you are passing a null bitmap object

 Bitmap icon = mBitmap;

you need to assign bitmap first then the code will start work

hello roman you need to pass your drawable or image source as a **URI** first and then you can send that URI by using below intent :- Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage); shareIntent.setType("image/jpeg"); startActivity(Intent.createChooser(shareIntent,"Share Image")); please note **uriToImage** is object which will store your image resource as uri – kuljeet singh Aug 06 '15 at 07:15

and please see my edited answer I have updated the link you can find a information https://github.com/codepath/android_guides/wiki/Sharing-Content-with-Intents – kuljeet singh Aug 06 '15 at 07:17
icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);..as per error line it shows issuie here – Aditya Aug 06 '15 at 07:24

the thing is object "icon" is null means there is no image bitmap in it . so you need to assign the bitmap or image as a bitmap to object "icon" – kuljeet singh Aug 06 '15 at 07:27

First Convert your drwable to image and store it on SDCard

Store Drawable to SD card

Then

private void shareImage() {
        Intent share = new Intent(Intent.ACTION_SEND);

        // setType("image/png"); OR for jpeg: setType("image/jpeg");
        share.setType("image/*");

        // Make sure you put example png image named yourImg.png in your
        // directory

        String imagePath = Environment.getExternalStorageDirectory()
                + "/yourImg.png";

        File imageFileToShare = new File(imagePath);

        Uri uri = Uri.fromFile(imageFileToShare);
        share.putExtra(Intent.EXTRA_STREAM, uri);

        startActivity(Intent.createChooser(share, "Share Image!"));
    }
