timertask

I want o make threads execute at specific exact times (for example at: 2012-07-11 13:12:24 and 2012-07-11 15:23:45) I checked ScheduledExecutorService , but it only supports executing after specific period from the first run and I don't have any fixed periods, instead I have times from database to execute tasks on. In a previous question for a different problem here , TimerTask was the solution, but obviuosly I can't make thread a TimerTask as Runnable and TimerTask both have the method run which needs to be implemented. The question here if I make the thread extends TimerTask and have one

What are the differences between these methods (classes)? I want to run a app that runs every 5 seconds, clear the memory when it is finished and when the cpu is in standby mode, that you can run the app. So that the app is not bound to a wakelock. Regards, Shafqat The difference between first three is just the amount of work that has been done for you. And a Service is a fundamental Android application component . AsyncTask as a convenience class for doing some work on a new thread and use the results on the thread from which it got called (usually the UI thread) when finished. It's just a

I suspect an exception could make the TimerTask stop running in which case I most likely need a second timetask to monitor that the first is still running? Update Thanks for the answers. I had inherited this code so a bit ignorant... I just saw that if I throw an uncaught exception in my job the TimerThread ceases to run forever. Run method of TimerThread showed that if an exception is thrown, my scheduled thread never runs again. public void run() { try { mainLoop(); } finally { // Someone killed this Thread, behave as if Timer cancelled synchronized(queue) { newTasksMayBeScheduled = false;

How can one ensure that a task that is supposed to run for x amount of time on an android os be run for that x period without user manipulation of date and time? For example, if I want this timer to run for 24 hours solid and then advise the user that 24h has passed, even if the phone is off for an hour, the user then turns it back on and sets the system time forward 2 hours, this timer would still indicate when that solid 24 hour period had passed without the user manipulating the system date/time and without connecting to the internet to verify the proper amount of time has passed. Thanks

I am creating an app that vibrate and beep every 30 sec and when I log out the vibrate and beep must be cancelled and when I log in the vibrate and beep should resume. NOTE: it must vibrate and beep for every 30 sec until I log out In my app I am using TimerTask for this implementation this is the code for vibrate and beep using TimerTask static TimerTask Task; final static Handler handler = new Handler(); static Timer t = new Timer(); public static void vib() { Task = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { Vibrator vibrator = (Vibrator)

I'm having a bit of an annoying problem. Right now, I have a snippet of code that starts a thread, sets a timer within that thread, and then exits that thread and continues with its life. My intent here was for the program to wait for the TimerTask to complete before continuing with code flow. However, obviously, setting up a new TimerTask doesn't pause execution to wait for the timer to run down. How do I set this up so that my code reaches the TimerTask, waits for the TimerTask to expire, and then continues? Should I even be using a Timer at all? I've looked everywhere for a solution, but I

I need my Android app to periodically fetch data from a server using AJAX calls, and update the UI accordingly (just a bunch of TextView s that need to be updated with setText() ). Note that this involves 2 tasks: Making an AJAX call, and updating the UI once I receive a response - I use a simple AsyncTask for this. Doing the above repeatedly, at regular intervals. I haven't figured out an elegant way to achieve Point 2 above. Currently, I am simply executing the task itself from OnPostExecute() . I read on this thread at SO that I need not worry about garbage collection as far as the

I'm writing a "Who Wants to Be a Millionare" game and I have everything set up, it's just a problem with the timer. The game works like this: if the user gets the question right he/she moves on. If not, the game is over and they can opt to play again. When the game first runs it's fine and the timer does what it should -- start at 30 seconds and count down, displaying the seconds. However, when the user clicks the "play again" button, the previous timer continues with the new timer. Like this: -timerA had 20 seconds left before the user lost (indicated by a). -timerB begins the next time the
