Android : Change default sms dialog for restore the sms not giving valid return value on kitkat

This code working properly on lollypop version, But, when i use it on Kitkat, it returns 0 when i choose "Yes" option from dialog.

btnSMSRestore.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
                if (currentapiVersion >= android.os.Build.VERSION_CODES.KITKAT){
                    defaultSmsApp = Telephony.Sms.getDefaultSmsPackage(SMSActivity.this);
                    if (!getPackageName().equals(defaultSmsApp))
                    {
                        Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
                        intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, getPackageName());
                        //startActivity(intent);
                        startActivityForResult(intent, DEF_SMS_REQ);
                    }
                }
                else
                {
                    new RestoreSMS().execute();
                }
    });

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case DEF_SMS_REQ:

if(resultCode == Activity.RESULT_OK) { new RestoreSMS().execute(); } } }

Activity.RESULT_OK value is -1 and resultCode in onActivityResult 0 when use with kitkat.

Please help me as soon as possible.
