Android :: Problem In GPS While Running In Timer
Nov 11, 2009
I am presently working on GPS. I have to start GPS periodically. I mean I want GPS to start after a particular interval, get Location value and then stop taking location updates. For this, I'm calling requestLocationUpdates( , , ) method in a timer. Then in onLocationChanged(), I stop taking location by using removeUpdates(). Then after particular interval, it again starts taking values, then when location changes, it stops, and so on.
Here is my code:
CODE:.............
Now the problem is:It starts fine for the first time,when location changes it stops then starts again,but the timer stops running after that.I dont get any error or exception.I dont know where is the problem.As far as I am concirned,the problem is in timer......

I have a class that is essentially a message manager (a singleton) that has a timer that polls for status. (statusPollerTask is just a derived class of TimerTask that has the run() defined)
timer.scheduleAtFixedRate(this.statusPollerTask, 0, 1000);
Several Activities register themselves with the msg-man for updates (observer pattern style) as they become visible. Works fine, except if the user presses the Home button and minimizes the app. Sometimes the timer keeps polling other times it doesn't. I need to maintain the polling even when the app is not visible. I feel like I'm just missing something simple here.

I came to know about Timer in android. I read http://android-developers.blogspot.com/2007/11/stitch-in-time.html that Timer is not available at Runtime.

I have a service that I need to execute every two minutes. Would it be more efficient to use an alarm or a timer?

What is the proper way to set a timer in android in order to kick off a task (a function that I create which does not change the UI)? Or there is a better way in android (android's handler)?

I'm looking for the best way to setup a timer for a game. For example I want the timer to tick down, but I want to be able to add to the timer when certain levels are reached etc. I'm just looking for the most efficient way to accomplish this. it only needs to be every second or so. If anyone has any insight on this.

I am new to Android development and have been working on a simple demo app that needs to update a TextView a few times from an array after a button is clicked. I have read and adapted the code found here to achieve this: http://developer.android.com /resources /articles /timed-ui-updates.html

I would like to know how to intercept the event that the apk has been updated in order to launch again my Timer. Indeed, I have a Timer wich is "scheduled AtFixedRate", but when my App is updated through the market, the timer is killed ; and if the user doesn't launch the App, the timer is not started (so my app becomes useless). How could I do to avoid it ? Is there an event to catch the "App updated" ? I searched, tried, but nothing.

I have to give a 20x20 presentation tomorrow and I'm looking for a timer app to help out. 20x20 means that each slide auto-advances after 20 seconds. I'd like to have a timer on my phone that would give me a quick glance of how much time I have left for each slide. Start it at 20 seconds, have it count down and when it hits zero, start over at 20. Seeing as it's just a timer app, I really would rather not pay $2 for StopWatch & Timer, which is the only one I've found that offers a looping timer. Does anyone have any ideas?

In order to get XML data from a server repeatedly, I'm attempting to use AsyncTask and Timer as per Mark Murphy's suggestion. I get the following error:01-07 16:11:26.705: ERROR/AndroidRuntime(729): Caused by: java.lang.Runtime Exception: Can't create handler inside thread that has not called Looper.prepare()I'm using SDK 1.5 with Eclipse on Windows.I've looked in documentation, on StackOverflow and in the Android Developers group, but I'm not clear what's causing the error or how to fix it.I can get the data once - i.e. without Async and Timer - and parse it via SAX without problems.s: I'm quite new to Android.

Is there a timer within Android that can be set for a given interval and when the interval has elapsed to send a signal back to a listener routine inthe main programme? Something like the way a button reacts when clicked.

I am using a Timer in my android application, but i can't get it to work. When I start my application the Timer simply does not start. The application continues but does not update.The long "toStart" finds the number of seconds left of the current minute, and thereafter the period is set to 60 seconds. The TimerTask simply calls a method.

Is there an app that lets you set a countdown timer on another app which causes it to force close. For example, I use my Eris as my MP3 player and would like to listen to it while I go to sleep, however I don't wanna let it play all night while I'm sleeping maybe just an hour or so.*Edit* Nevermind I found an app that does the job. Its called Music Sleep. It lets you set a timer that will close your music app in case anyone else was interested. It only costs 99 cents

I have an activity that uses a Timer (java.util.Timer) to control the display. I set it off to repeat its run() method every second or so. When it runs, it updates some View elements.
As Timer runs in its own thread, I assumed this would be reliable. But I notice that sometimes there is a stutter, or delay, in the views updating. It's like they occasionally get stacked up, and all happen together. Studying the output from logcat, I notice that this happens when the device is doing something else - some system functions, or sometimes a garbage collection.
How can I avoid this? I'm not aware I can run the main activity in a thread of its own, can I? If the timer has its own thread, why is it affected?

I've created an app that functions as a countdown timer via a thread, a wakelock, and a handler back to my activity. My question is, what will cause my thread to die, or app to not be running in memory anymore? I've had this happen once, and can't seem to recreate it again.

Could someone explain how to use the Timer.schedule - that is used for scheduling tasks - in Python? Note that Python's time.sleep will not work in Android.

I need to create a Timer to update the UI at regular intervals. But the Swing Timer class is not available on Android. (I would avoid creating threads and then use the Timer class from java.util package)

I was rather surprised to find a couple of features missing from android, having just moved from a sony-ericsson w200i (a phone which i bought for a fifth of the price of my new galaxy), in which these features seemed obvious
i did get tone picker to sort out the lacking ringtone settings etc. but when i tried to find a simple countdown app i hit a bit of a wall
from the ones i tested out, "oi countdown" and "countdown alarm" seemed to work ok up until the point the alarm rang and i couldn't shut the thing up in any other way than booting the whole phone
"snappy countdown timer" is the closest i've found for a simple app to remind you when your pizza is done, but that has the annoying issue of the ui being way too sensitive to pick a specific time (on minute-scale)
so is there a simple app to do the job of an egg timer that actually works?
