how to read/write sms body into a shared preference file onReceive

am trying to write an sms body into a shared preference file when onReceive method is invoked, but seems not to work. i have a class receiverClass which extends BroadcastReceiver and SessionManager is my shared preference class below is what i tried which doesn't work if i declare sessionManager globally else it displays the toast msg when it actually receives a new msg when SessionManager isn't declared.

public class receiverClass extends BroadcastReceiver{
SessionManager session;

    @Override
    public void onReceive(Context context, Intent intent) {
      String sendingNumber="";
      String smsBody=""; 
      Bundle bundle=intent.getExtras();
                  SmsMessage[] msgs = null;
                  String smsBody1="";
                    if (bundle!=null) {
                          Object[] pdus=(Object[])bundle.get("pdus");
                          msgs=new SmsMessage[pdus.length];
                          for (int i = 0; i < pdus.length; i++) {
                                msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                                sendingNumber += msgs[i].getOriginatingAddress();
                                smsBody1=msgs[i].getMessageBody().toString(); 
                            }
              Toast.makeText(context, "Remote Access " + smsBody1, Toast.LENGTH_SHORT).show();

              session.onSmsBody(sendingNumber,smsBody1);

        }
    }

however i also tried with sqlite database which crashes my application when a new sms is received even if the application is not opened. below is code with sqlite database and its class

public class DBController extends SQLiteOpenHelper{
private static final String LOGCAT = null;

public DBController(Context receiverClass) {
    super(receiverClass, "SMSsqlite.db", null, 1);
    Log.d(LOGCAT,"Created");
}

@Override
public void onCreate(SQLiteDatabase database) {
    String query;
    query = "CREATE TABLE SMS_configuration ( smsId INTEGER PRIMARY KEY, originatingAdress TEXT, smsBody TEXT)";
    database.execSQL(query);
    Log.d(LOGCAT,"SMS_configuration Created");
}

@Override
public void onUpgrade(SQLiteDatabase database, int version_old, int current_version) {
    String query;
    query = "DROP TABLE IF EXISTS SMS_configuration";
    database.execSQL(query);
    onCreate(database);
}

public void insertSms(HashMap<String, String> queryValuesOrig, HashMap<String, String> queryValuesBody) {
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put("originatingAdress", queryValuesOrig.get("originatingAdress"));
    values.put("smsBody", queryValuesBody.get("smsBody"));
    database.insert("SMS_configuration", null, values);
    database.close();
}

}

and receiverClass Class

public class receiverClass extends BroadcastReceiver{


    @Override
    public void onReceive(Context context, Intent intent) {
      String sendingNumber="";
      String smsBody=""; 
      Bundle bundle=intent.getExtras();
                  SmsMessage[] msgs = null;
                  String smsBody1="";
                    if (bundle!=null) {
                          Object[] pdus=(Object[])bundle.get("pdus");
                          msgs=new SmsMessage[pdus.length];
                          for (int i = 0; i < pdus.length; i++) {
                                msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                                sendingNumber += msgs[i].getOriginatingAddress();
                                smsBody1=msgs[i].getMessageBody().toString(); 
                            }
              Toast.makeText(context, "Remote Access " + smsBody1, Toast.LENGTH_SHORT).show();

              addNewConfig(sendingNumber,smsBody1);

        }
    }

    public void addNewConfig(String sendingNumber, String smsBody1) {
         DBController controller = new DBController(null);
        HashMap<String, String> queryValuesOrig =  new  HashMap<String, String>();
        HashMap<String, String> queryValuesBody =  new  HashMap<String, String>();
        queryValuesOrig.put("originatingAdress", sendingNumber.toString());
        queryValuesBody.put("smsBody", smsBody1.toString());
        controller.insertSms(queryValuesOrig,queryValuesBody);
    }
}

and my manifest file looks like this

  <uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" />

receiver android:name=".receiverClass" android:exported="true">
        <intent-filter android:priority="999">

            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>

all i want to do is write the sms body onReceive into a shared preference file or sqlite database where i would be using later and application is being runned on a kitkat device and am also aware of the security issues but is there's a solution for this i would gladly need ty.
