Create a check for the facebook before sharing the data following is an example

 public void shareIntent(){
        String urlToShare = "http://stackoverflow.com/questions/7545254";
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("text/plain");
// intent.putExtra(Intent.EXTRA_SUBJECT, "Foo bar"); // NB: has no effect!
        intent.putExtra(Intent.EXTRA_TEXT, urlToShare);

// See if official Facebook app is found
        boolean facebookAppFound = false;
        List matches = act.getPackageManager().queryIntentActivities(intent, 0);
        for (ResolveInfo info : matches) {
            if (info.activityInfo.packageName.toLowerCase().startsWith("com.facebook.katana")) {
                intent.setPackage(info.activityInfo.packageName);
                facebookAppFound = true;
                break;
            }
        }

// As fallback, launch sharer.php in a browser
        if (!facebookAppFound) {
            String sharerUrl = "https://www.facebook.com/sharer/sharer.php?u=" + urlToShare;
            intent = new Intent(Intent.ACTION_VIEW, Uri.parse(sharerUrl));
        }

        startActivity(intent);
    }
