            Intent sharing = new Intent(android.content.Intent.ACTION_SEND); 
            sharing.setClassName(,);
            sharing.setType("text/plain");
            sharing.putExtra(android.content.Intent.EXTRA_SUBJECT,"hello");
            sharing.putExtra(android.content.Intent.EXTRA_TEXT, "yahoomail");
