When I run my app in Android Studio I get the message "Unfortunately your App Appointment DB has stopped working". Not sure how to resolve this issue. Here is my code.

MainActivity.java

package com.example.android.appointmentdb;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends Activity {

    TextView idView;
    EditText clientNameBox;
    EditText clientPhoneBox;
    EditText clientTimeBox;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        idView = (TextView) findViewById(R.id.clientID);
        clientNameBox = (EditText) findViewById(R.id.clientName);
        clientPhoneBox =(EditText) findViewById(R.id.clientPhone);
        clientTimeBox =(EditText) findViewById(R.id.clientTime);
    }

    public void newClient (View view) {
        MyDBHandler dbHandler = new MyDBHandler(this, null, null, 1);


        String phone = clientPhoneBox.getText().toString();

        String name = clientNameBox.getText().toString();

        String time = clientTimeBox.getText().toString();

        Appointment newAppointment = new Appointment(name, phone, time);

        dbHandler.addClient(newAppointment);


        Toast.makeText(getApplicationContext(), "Your appointment is set =)",
                Toast.LENGTH_LONG).show();

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
