On older version of the facebook SDK I add this method to check facebook is installed on the user phone.

public boolean isFacebookAvailable() {

        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.putExtra(Intent.EXTRA_TEXT, "Test; please ignore");
        intent.setType("text/plain");

        final PackageManager pm = this.getApplicationContext().getPackageManager();
        for(ResolveInfo resolveInfo: pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)){
            ActivityInfo activity = resolveInfo.activityInfo;
            // Log.i("actividad ->", activity.name);
            if (activity.name.contains("com.facebook.katana")) {
                return true;
            }
        }
        return false;
    }

On the new facebook SDK they already have this validation, and let you login with a webview in case the user doesnt have fb installed. My opinion, install the new sdk.
