title: Android Java Time Picker Dialog
body: <p>hey I am trying to make a TimepickerDialog. But the app crashes soon as I press the Set Time button. Here is the code.</p>
  
  <p>MainActivity:</p>
  
  <pre><code>package com.wifitimer;
  import java.text.DateFormat;
  import java.util.Calendar;
  import android.app.Activity;
  import android.app.TimePickerDialog;
  import android.os.Bundle;
  import android.widget.TimePicker;
  
  public class MainActivity extends Activity {
  DateFormat formatDateTime=DateFormat.getDateTimeInstance();
  Calendar dateTime=Calendar.getInstance();
  
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  }
  
  public void chooseTime(){
      new TimePickerDialog(this, t, dateTime.get(Calendar.HOUR_OF_DAY), dateTime.get(Calendar.MINUTE), true).show();
  }
  
  TimePickerDialog.OnTimeSetListener t = new TimePickerDialog.OnTimeSetListener() {
      @Override
      public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
          dateTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
          dateTime.set(Calendar.MINUTE,minute);
      }
  };
  }
