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.

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?
As a part of my app I would like to include a countdown timer.
I would much rather have the timer count in minutes and seconds, so any good tutorial to set such a timer up I would rather they point me in that direction first (I have looked)
My problem is that I'm getting this error when I press the button to open the activity
02-27 21:07:47.776: E/AndroidRuntime(711): Uncaught handler: thread main exiting due to uncaught exception
02-27 21:07:47.786: E/AndroidRuntime(711): java.lang.RuntimeException: Unable to start activity ComponentInfo{converter.units.kitchen/converter.units.kitchen.Timer}: java.lang.NullPointerException
I currently have the following java activity
import
android.app.Activity;
import
android.os.Bundle;
import
android.os.CountDownTimer;
import
[code]....
It was working fine when I had a fixed number as the starting value, although since reverting to a fixed number it still does not work.
One thing that really bothers me about Google Now on a mobile device is that if you say "Set a timer for 'x' minutes" it will set an alarm (vs a countdown timer) for 'x' minutes into the future. If you say the same command to Google Search on Chrome on a PC it will set a countdown timer. I would really like it if I could just say "Okay Google (Now)... Set a timer for 10 minutes" and then have it start counting down.
Does KK updates Google Now to the ability to set a timer?
Is there any way to define countdown timer without specifying millisInFuture. i.e to have a countdown timer which stops only when explicitly stop() function called.

View 1 Replies View RelatedAnyone have experience with a good countdown timer that works well with Droid? I think I downloaded the "Ultimate Stopwatch" once and it didn't work well (The alarm sound was way too soft). There are dozens of timer apps, and it seems people have various problems with all of them, aside from maybe a few pay ones. But I just want something really simple. Just for timing things like cooking stuff in the oven and poker games. Any suggestions?

View 1 Replies View RelatedI'm trying to create a simple Workout Timer for Android. The user creates a WorkoutPlan containing info such as total duration, total rest time, etc, the app will display a timer that updates every second.
Pretty simple to begin with, but I'm trying to build the app as properly as possible, i.e. separation of concern, correct techniques, responsive UI, ensure the timer will be accurate, etc.
Here's a simplification of what I have so far:
WorkoutPlan, the user can load/save different workout plans to the timer
Code:
public class WorkoutPlan {
public long duration;
}
TimerThread, this class implements `Runnable`, it takes in a `WorkoutPlan` in the constructor, start/stop, shows elapsed time.
Code:
public class TimerThread implements Runnable {
public boolean running = false;
[Code]....
TimerView, the custom view that displays the elapsed time
Code:
public class TimerView extends View {
private final Paint mBg;
private final Paint mText;
private WorkoutPlan plan;
private TimerThread timer;
private Thread thread;
private Handler handler = new TimerHandler();
[Code]...
Finally, WorkoutTimer, the activity that starts it off
Code:
public class WorkoutTimer extends Activity {
private TimerView mTimer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
[Code]....
A couple of questions:
Where's the best place to create the `WorkoutPlan` object? Currently it's done in `TimerView`. Should it be done in the `WorkoutTimer` activity instead? If yes, how do I pass the `WorkoutPlan` object to `TimerView`?
The app works fine the first time, but crashes when I go to the home screen then back to the app the second time. What's causing it to crash? Is it the theading?
Currently I'm using a `Handler` in a new `Thread`. Is this ok or would a `TimerTask` be better? Where's the best place to start the thread? Am I correct to put all the threading code in `TimerView`?
Am I correct to add synchronized to all the methods in `TimerThread`?
Wondering if there is an app or widget that does a countdown to a certain day? With the ability to enter your own date that you want to countdown to.

View 1 Replies View RelatedI am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

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.
View 4 Replies View RelatedI 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?
