I'm calling this tasks:
CODE:.........
And here are the two TimerTasks:
CODE:........
As you can see, I just call a method after 5 resp. 10 seconds. From time to time I would like to pause the "countdown". This means i want that the time until the 5 seconds are passed isn't running anymore. And then in a later point in time, I would like to resume it. How can I achieve that?

Can I rely on Timer and TimerTask to work properly on Android?
I have a background Service with a single Timer, and I schedule (possibly multiple) TimerTask's via Timer.schedule()
At the beginning of each implemented TimerTask.run() method, I check the TimerTask.scheduledExecutionTime() and compare it with the current time. Sometimes things are fine, and the difference is a small number of ms. But sometimes things are nowhere near fine, and the invocation of my TimerTask is *way* late -- like multiple hours late.
Can an Android phone go into some deep sleep mode when it doesn't think anything is going on that would cause a TimerTask to be so late? Can I not reliably use TimerTask for scheduling events, and should I be using some Android-specific means (e.g. the AlarmManager, or a Handler) instead?
I have not found anything that says that java.util.TimerTask shouldn't be sufficient, the Android docs include no kinds of qualifiers, and this post (from Mark Murphy, who's written several good Android books) specifically mentions it as being available:

Is it a no-no to try to update a View from a TimerTask? My initial experiments indicate it doesn't work. Is there a way to make it work?
View 3 Replies View RelatedI have noticed that when display goes to sleep, my TimerTask is also freezed, until display is waked up. I need my TimerTask to execute (a BlueTooth operation every few minutes) even while the display is sleeping.
How do i achieve this (eventually using something else instead of a TimerTask)?
I have one simple question regarding Java TimerTask. How do I pause/resume two TimerTask tasks based on a certain condition? For example I have two timers that run between each other. When a certain condition has been met inside the task of first timer, the first timer stops and starts the second timer, and the same thing happens when a certain condition has been met inside the task of second timer.how do I pause timer1 while running timer2 and vice versa while timer2 is running? Performance and timing is my main concern as this needs to be implemented inside another running thread. By the way I am trying to implement these concurrent timers on Android.
View 4 Replies View RelatedI am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?

View 2 Replies View RelatedThis is what the Java site www.java.com says: "KVM, the virtual machine for mobile devices, is the counterpart of JVM (Java virtual machine). It is used to run applets and applications written with Java technology on mobile devices. KVM must be installed by the manufacturer. It is NOT available for download or installation by consumers". Now Android has a customized virtual machine called DVM (Dalvik Virtual Machine). Can we compare it with KVM? Wonder if we can further reprogram DVM to incorporate features of KVM to run applets on Android? Same goes for Blacberry, is there a possibility?

I have a HTC HD2 which had WinMo before. Long time ago I changed it to Android. Couple of days ago, I wanted to change to a new Android version so I deleted the whole OS on my Android to install a new one.I got stuck on the Magdlr option because I couldn't go select any option. I realized then, that my call button is broken! how it is possible to install Android, because WinMo sucks!!

The Magic has the back button closer to the trackball, which is much easier to access.Anyone else have the same experience? Or am I the only one that uses this button quite often?Is there a possibility to re-map the hardware buttons?
View 4 Replies View RelatedThis thread will probably be best answered by devs who have the full knowledge of how our phones' internal 'stuff' works. But anyone with a decent idea/answer is welcomed to enlighten us.
With all the excitement about the 2.1 update and rooting the Droid and using custom ROMs, overclocking..etc..what exactly is it that allows a person to perform such actions? I've read on this site and a few other places that Motorola will be 'locking' the ability to root our phones with the 2.1 update.
One of Motorola's support pages has a posting from some lady that stated just because the OS is open source, does not mean that the devices have to be open to user configuration beyond what the manufacturer has available for us. She went on to say that when a certain business decision is made to allow for such access, it will be made based on certain factors....
I can't find the link to that page anymore. It was posted on Facebook the other day, so forgive me for lack of a link to show what I'm talking about in above paragraph.
I guess my real question is what do they do to the phones OS that blocks this ability to root?
And of course, if they can lock it up, can't some devs just 'unlock' it again? I have minimal to no knowledge of Linux and the ability to create/modify system files on these phones so I am leary about unrooting my phone to see what the 2.1 update will encompass. Yet I want to, just to see how well it works and what it offers.
Wondering if this is possible. I am trying to go to paperless flight check in for my airline. Continental sends me email with url link to my boarding pass. (I have HTC Incredible). Problem is, I cant download or save the boarding pass to by phone. Instead I need to rely on connecting to that link from email when I go thru security. This is very risky if link is down or 3G signal is weak. Wondering if theres anyway to download/save the web page in advance?

As far as I know, if an owner of an android smartphone decides to flash/update his phone by not using the official ways (by smartphone via wi-fi or by pc via Kies), then he permanently loses a possibility to update his phone officially.
I know that because I used to have Galaxy S2 and installed a custom firmware, although there was a trick when you use some stick to have your phone "official" again.
So, I'm not comfortable with the "latest" android OS 2.3.6, S6802XXLF2 / Gingerbread.XXLF4 My phone is GT-S6802 Ace Duos. I'm not comfortable due to the fact that the default browser doesn't have an exit button, so I have to resort to task manager in order to kill the process of internet browser - which is an oversight by android devs.
But I know, that in some new firmwares the default internet browser has an exit button, so I'm wondering if there's any firmware to which I can upgrade without losing the possibility to update my smartphone afterwards.
Also, I take it, for every smartphone there's certain firmware version, right?
For example, for Galaxy S3 it's Android 4.0.4
While for Galaxy Ace Duos it's Android 2.3.6
And the OS of Galaxy S3 can't be installed onto Ace Duos, right?
This is sad, why can't Samsung make one universal OS for its smartphones? Does Windows Mobile has the same issue? Or is it universal just like PC Windows OS?

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
