My Scenario is to show Greeting notification to my users even they are not using the app. Below code is working fine if the open is opened or minimized. But, I want to show the notification in morning even though the user did not open the application.
Main Activity:
public class MainActivity extends Activity {
private PendingIntent pendingIntent;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 18);
calendar.set(Calendar.MINUTE, 40);
calendar.set(Calendar.SECOND, 0);
Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
} //end onCreate
}
My Receiver Class:
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{
/*Intent service1 = new Intent(context, MyAlarmService.class);
context.startService(service1);*/
try{
Utils.generateNotification(context);
}catch(Exception e){
e.printStackTrace();
}
}
}
Utils Class:
public class Utils {
public static NotificationManager mManager;
@SuppressWarnings("static-access")
public static void generateNotification(Context context){
mManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
Intent intent1 = new Intent(context,MainActivity.class);
Notification notification = new Notification(R.drawable.ic_launcher,"This is a test message!", System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(context,0, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(context, "AlarmManagerDemo", "This is a test message!", pendingNotificationIntent);
mManager.notify(0, notification);
}
}
My Alarm Service:
public class MyAlarmService extends Service {
@Override
public IBinder onBind(Intent arg0)
{
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate()
{
// TODO Auto-generated method stub
super.onCreate();
}
@Override
public void onStart(Intent intent, int startId)
{
super.onStart(intent, startId);
}
@Override
public void onDestroy()
{
// TODO Auto-generated method stub
super.onDestroy();
}
}
Next Activity:
public class NextActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
