I use an AlarmManager to run a Service which tries to download a file from the web. If it fails I'd like to retry that Service in 5 minutes.
Inside the Service I run an AsyncTask to run my code. As far as I know the only way I can tell if it failed or not is from the onPostExecute().
What is the best way of implementing a retry of that Service again?

I have an activity that starts with an AsyncTask to check the connection to my servers api.
Since this should not run in the UI thread i have made a AsyncTask for this.
The problem is that is get an runtime exception when i start the background process of the Asynctask.
How can i avoid this?
From log:
code:.........................
I am using an AsyncTask to fetch the ring tone for a contact when my application starts, it works fine until after my Activity closes a couple of times during the AsyncTask, after this happens the AsyncTask will only ever get to onPreExecute() and never doInBackground, so I can never fetch the ringtone then until either a force stop or device restart.
Why this might be happening? Why the AsyncTask would get to onPreExecute but then never run doInBackground()?
Here is my code: (Following the Shelves source code)
CODE:.....................
And onAddRingtone() is used in onCreate and onCancelRingTone() is used in onDestroy() as well as where you can see if in the code above. I have spent 3 days on this and I haven't been able to find a solution? Am I taking the wrong approach? Using cancel wrong? Is there a bug?
I've tried downloading multiple different apps today and every time, the download almost immediately fails and says "download unsuccessful"
View 14 Replies View RelatedI'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:
CODE:...........
When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?

I have a Galaxy S3, running Omega v33.2 (4.1.2).
My time and date settings are correct, and haven't changed from when Play Store was working.
I've uninstalled Play Store updates.
I've tried clearing the cache from Play Store.
I've installed a modded Play Store, (ChelpuS), to see if this makes any difference.
Play store had been opening and working correctly until just 2 days ago, the last things I downloaded through it were "Freeze" and "1Weather".

This is pretty annoying, as so far I've tried:

I am currently setting an alarm to fire off a background service every 2 minutes in order to check my server for certain updates. Now if I start the app and my screen is on and not locked the phone plays the sound I need it to play and opens the activity. Thats great. But the way I need it to happen is if the screen is off and the phone locked I still need it to check every two minutes and I need it to play that sound and open the activity that is needed. This does not happen for some reason. Could someone explain to me why the alarm doesn't function when my app is not "running" (by this i mean the app is marked as a running process but not actually visible to the user) and the screen is off? The code for the timer is below: CODE:.............

I have set a alarm,but now i want to delete it? how can i make it.
I think I'm reading some conflicting statements about the AlarmManager on the Android docs website. The following statements both exist on this page:
http://developer.android.com/reference/android/app/AlarmManager.html
[at the top]
"Registered alarms are retained while the device is asleep (and can optionally wake the device up if they go off during that time), but will be cleared if it is turned off and rebooted."
- and -
[under setRepeating()]
"This alarm continues repeating until explicitly removed with cancel(PendingIntent)"
So, the question is, do I need to register a BootReceiver that re-sets my Alarms when the phone turns on. The first statement makes me think I do, but the second statement is worded in a way that would lead one to believe that it would live forever, unless a cancel() call on that Intent is called.
So, which statement do I believe or am I misinterpreting one of the statements? I suppose when the power is turned off or back on, Android itself could call the cancel() function on all alarms. I guess it would help if it said that after the second sentence.
Show me some sample code on how to use an AlarmManager in android.
I have been playing around with some code for a few days and it just won't work...
I need to trigger a block of code after 20 minutes from the AlarmManager being set.
I changed AlarmController.java in ApiDemo a little bit, so I want the alarm not to go off when the phone is sleeping by using AlarmManager.RTC.
CODE:.................
The receiver code is like below:
CODE:..............
I ran the modified app, but I still see many log messages as below after the phone wento sleep (the screen was black):
CODE:...............
This means the flag AlarmManager.RTC didn't work.
I have a AppWidget, after I delete it from HomeScreen it seems not stopping the AlarmManager attached with it. I have supported it with the AlarmManger, that call the ProviderImplementation class every 1 minute and in onReceive I put the code to call onUpdate. and in onDelete I explicitly stop the alarm, but it seems it is running continously and not stopping. any cure of it ?
I have stopped it with cancel(pendingintent) function.
I have a service that I need to execute every two minutes. Would it be more efficient to use an alarm or a timer?
View 3 Replies View RelatedI am trying to create intents that will be set using alarmmanager. Currently, I can do this with one intent, add extra data to it (strings, but i send them as one string with a seperator), and everything works fine and goes off at the correct time. However, when I try to send multiple intents like this, they are overwritten and only one goes off at the correct time. How can i structure my intents so that they appear different to the alarmmanager (i think they are getting deleted when filterIntent() is run).
long story short- putExtra() makes all the intents look the same still... how can i make them look different so they wont get deleted (and keep track of them in case i want to delete a specific one)
I've created a simple app widget for personal use that queries a site from the internet, parses the XML received and displays some info from it. I'm using a Droid X, if that makes a difference; both in the emulator and as physical hardware, developing in the Android version of the MotoDev IDE.
No matter what I put in updatePeriodMillis, the shortest refresh time I can get is 30 minutes (I thought this was a 1.6 only bug but apparently not since I'm running 2.1) and I want it to refresh every 5 minutes, with some caveats. I don't want the widget to refresh when the screen is off and I want it to refresh immediately upon waking up the screen. My search for information says to set updatePeriodMillis to 0 and use the AlarmManager instead, but I can't find any complete code examples on just how to do this.
Obviously, I'm new to Android development, and Java in general actually, but I've been a developer for a very long time with experience in just about every other language. Currently working in C#, so I thought I'd be able to jump in fairly easily. Can anyone point me to sample code or an open source project that does what I'm looking for? I have other questions, but until I get this piece working they don't really matter. :)
Any experts on AlarmManager out there?I've got something weird going on.The basic code to set my repeating alarm works fine. I can close my app and the alarm will continue to run like clockwork every five minutes. It works fine only if I set it in the app and then close the app.I've got a registered BootReceiver for re-registering the repeating alarm. I know it fires on boot b/c the log message clearly shows it is firing and re-setting the repeating alarm in question for the same frequency. But the AlarmManager is not firing.Basically, the nearly identical code for setRepeating() fires when set from the app and continues to run when the app is closed, so I know my AlarmReceiver is functioning, but the AlarmManager is either not broadcasting this alarm or my receiver doesn't work from an alarm set in the boot receiver.
View 9 Replies View RelatedI wanted to ask a question regarding the Alarm Manager. I have a requirements of setting long running timers in my application. The minimum duration for my timer is 1 hour...and the maximum may be for 4-5 days. This timer is supposed to run in the background, and when it fires/expires, i have to show something on the GUI. The timer can be re-scheduled once it fires based on user action.
What is the best approach for scheduling such long running timers ?
Should i make use of the Alarm Manager ? Or will it be an overkill ? As far as i know, alarms are retained even if the device goes to sleep and they wake up the device when the alarm goes off.
I am thinking of using a simple Java TimerTask as an alternative to setting an alarm: http://java.sun.com/j2se/1.5.0/docs/api/java/util/TimerTask.html.
But i am not sure what will happen to the timer task if the device went to sleep while the task was running.
I'm having some strange behavior of wakeup alarms scheduled by AlarmManager in Motorola Milestone (Droid in US). The thing is that they don't wake the device as they should. The same piece of code works fine in Samsung Galaxy and the alarms are fired as they should fire. In Milesstone when the device is in sleep no alarms are fired but all the alarms are fired at once when the device wakes up. I also found out that Milestone doesn't have the /proc/wakelocks file to check the wake lock info but I'm not sure if that has something to do with the problem. For this scenario there is no reason to acquire a wakelock because the AlarmManager acquires it automatically for lifetime of the OnAlarmReceive. I found some other threads about the same problem in Droid/Milestone, but does anybody have an idea what is the problem and is there anyway to solve it.
This is the code that I'm using to test this.

I have a question about the background thread handling change that went into SDK 1.6. I read here that BG threads get placed in a scheduling class that can't use more than 5-10% of the CPU in order to keep the foreground responsive. Do system services get into that scheduling class?
My app uses repeating alarms. It was great with 1.5, very reliable. Since the upgrade to 1.6, the phone seems to be dropping some of my repeating broadcasts, especially if I am doing something fun in the foreground like with WIFI when the Alarm is supposed to fire. I do not have any of the task killer programs that have been a hot topic lately. To be clear, the dropped alarm broadcast behavior is intermittent. I am not 100% sure if I really am doing something when it has failed. If the timer is a one shot, it seems to work better but there is no real empirical evidence here. My phone is usually in my pocket when I fire one of the one shot alarms. If my theory about system services in the background scheduling class is correct, then I probably cannot find a workaround or defensively code a solution. Will it be the same in 2.0?
Have others seen issues with alarms and with the setRepeating method? I am looking for suggestions to troubleshoot this problem. How can I determine if the problem is the broadcast, if it is the repeating alarm creation, or if there is some other issue like low memory coming in to play.
