Multiple Alarm Problem

Hi All,

I am able to execute single alarm app successfull, but if i make using for multiple alarms then i am facing the problem. The problem is if we set for the different alarm timings but we are able to get alarm for only once
(For example if button1 set for 15secs,button2 set for 30secs and button3 sets for 45secs. If button2 get selected after selecting button1 and button3 then alarm notification shows only for 30secs how to show the alarm for 3 timings).

Thanks,
Satish

Hello satish,

The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.

Have a look at this post, where I described how to do time-delayed invocation of "things":
:arrow:

http://www.anddev.org/viewtopic.php?p=3188#3188

It basically wirks like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

     public void onCreate(Bundle icicle) {
 
          super.onCreate(icicle);
 
          setContentView(R.layout.splashscreen);
 
          /* New Handler to start the Menu-Activity
 
           * and close this Splash-Screen after some seconds.*/
 
          new Handler().postDelayed(new Runnable(){
 
               @Override
 
               public void run() {
 
                    /* Create an Intent that will start the Menu-Activity. */
 
                    Intent mainIntent = new Intent(Splash.this,Menu.class);
 
                    Splash.this.startActivity(mainIntent);
 
                    Splash.this.finish();
 
               }
 
          }, SPLASH_DISPLAY_LENGHT);
 
     }

Hello satish,

Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running.

So in my view the Alarm Manager shall be used to wake your program up at a specific time.
You could do the following if the user selected more than one program to be notified of:

Get the earliest one and set the Alarm Manager to wake program up on that time.
Then internally work with Handler as long as Program is running
If program is sent to background (would probably be onFreeze() or sth.), repeat step 1.

Thats how I would do it.

:idea:

The Handler-Class also provides a method postAtTime (probably only works if application is running!):

postAtTime(Runnable r, long uptimeMillis)
Causes the Runnable r to be added to the message queue, to be run at a specific time given by uptimeMillis.

Hope I could help you.

plusminus
