  <p>I don't understand why this error occurs.</p>
  
  <p>I am trying to appear notification at specific time and after searching for a time i found this <a href="https://stackoverflow.com/q/7540724/1250370">old stackoverflow question</a>. I tried everything but my code gives error.</p>
  
  <p>Please help me to solve this problem.</p>
  
  <p>Here is my MainActivity code:</p>
  
  <pre><code>public class MainActivity extends Activity {
      int mHour, mMinute;
      ReminderService reminderService;
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          reminderService = new ReminderService("ReminderService");
  
          TimePickerDialog dialog = new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, false);
          dialog.show();
      }
  
      TimePickerDialog.OnTimeSetListener mTimeSetListener =  new OnTimeSetListener() {
  
          @Override
          public void onTimeSet(TimePicker v, int hourOfDay, int minute) {
              mHour = hourOfDay;
              mMinute = minute;
  
              AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
              Calendar c = Calendar.getInstance();
              c.set(Calendar.YEAR, Calendar.YEAR);
              c.set(Calendar.MONTH, Calendar.MONTH);
              c.set(Calendar.DAY_OF_MONTH, Calendar.DAY_OF_MONTH);
              c.set(Calendar.HOUR_OF_DAY, mHour);
              c.set(Calendar.MINUTE, mMinute);
              c.set(Calendar.SECOND, 0);
  
              long timeInMills = c.getTimeInMillis();
  
              Intent intent = new Intent(MainActivity.this, ReminderService.class);
              PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0, intent, 0);
              alarmManager.set(AlarmManager.RTC, timeInMills, pendingIntent);
          }
      };
  
  }
  </code></pre>
  
  <p>and here is my ReminderService code:</p>
  
  <pre><code>public class ReminderService extends IntentService {
  
      public ReminderService(String name) {
          super(name);
          // TODO Auto-generated constructor stub
      }
  
      @Override
      protected void onHandleIntent(Intent intent) {
  
          Intent notificationIntent = new Intent(this, MainActivity.class);
          PendingIntent contentIntent = PendingIntent.getActivity(this, 1, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
  
          NotificationManager nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
  
          Notification.Builder builder = new Notification.Builder(this);
  
          builder.setContentIntent(contentIntent)
              .setSmallIcon(R.drawable.ic_launcher)
              .setTicker("Local Notification Ticker")
              .setWhen(System.currentTimeMillis())
              .setAutoCancel(true)
              .setContentTitle("Local Notification")
              .setContentText("This is content text.");
           Notification n = builder.getNotification();
  
           nm.notify(1, n);
      }
  
  }
  </code></pre>
  
  <p>and here is my manifest.xml:</p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"

      &lt;/application&gt;
  
  &lt;/manifest&gt;
