You have to do some operations before you share your image, so add the permission in your Manifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Fist, create a Bitmap object from your drawable resource:

Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx);

Then, get the path for you share your image

String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/yourImage.jpg";
OutputStream out = null;
File file=new File(path);
try {
    out = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
    out.flush();
    out.close();
} catch (Exception e) {
    e.printStackTrace();
}
path=file.getPath();
Uri uri = Uri.parse("file://"+path);

And finally, create your intent:

Intent intent = new Intent();
intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/jpg");
startActivity(Intent.createChooser(intent,"Share with..."));
