I 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 an compiled executable that is supposed to copy itself from the res folder, and into the /data/data/package-name/ folder, and change the permissions, and then execute. Every step completes all the way to the end. The output stream seems to be writing, etc. Except when I go check the file system, nothing has been done. I first tried with 'sh' then with 'su' (I have a rooted Cyanogen rom).
Here is the code:

Can anybody tell me what method of an activity executes when an application closes?. Like I have a main activity and if I press back button on my phone. The Application closes so I want to know what method executes at that time.

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 RelatedThe android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity?

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?
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 RelatedI am quite impressed by the workflow I follow when developing Android applications: Define a layout in an xml file and then write all the code in a code-behind style. Is there an equivalent style for the web? I mean, with a predefined list of widgets that can be defined using a markup language and then control them using code? I have come across Google's Web Toolkit that does something like this but I'd like to hear what other's think as well.
View 3 Replies View RelatedI am new to the Droid world and was curious as to if there was a real competitive Voice Command app, similar to MS's? I came over from ATT using Win Mobile devices. While I disliked many things about WinMobile, I really liked the Voice Command. It wasnt perfect but I liked using it. I even thought it was great how it would read Text messages aloud to me through the speaker when I received them.Is there anything that can do that or more for Android phones yet? I know they have the basic Voice Calling thing but is there anything else? Maybe even something that will read text messages outloud when they arrive?

For those who know about Lose It! and would like to see it on Android, you can send an email to them requesting it and hope for the best. I already have.

View 6 Replies View RelatedHere's my scenario. I have an app that is playing backgound sounds. Using the BroadcastReceiver I can tell when the display turns off, and then kill the sounds. I can also tell if the screen turns back on. However, if the device is in the lock state I don't want the audio to start. Therefore I wait for the ACTION_USER_PRESENT intent to signal. That all works, except that if the user turns the screen back on quickly after it was turned off, you don't get the lock screen or the ACTION_USER_PRESENT message. So, is there a way to tell, when the screen turns back on, if the device is locked or not, which I guess also means sleeping or not?
