I am trying to create AlarmManager in BOOT_COMPLETED BroadcastReceiver.
It is NOT working, AlarmManager Receiver is never fired.

I have a BroadcastReceiver which never enters onReceive(), so to debug I created a bare bones project with a simple BroadcastReceiver and still it never gets the BOOT_COMPLETED intent (see manifest below).
I do see a lot of warnings/errors in my Eclipse log (filtered and after manifest) which didn't seem to cause issues before, but maybe I have a bad install of the emulator? I have all the latest SDK and plugins. I also noticed that when I run the emulator I always get "Waiting for" popup for either Alarm or MMS.
The debugger attaches normally for my main Activity, it's just this "boot" receiver that never seems to start. I've tried using "com.boottest.BootReceiver" instead of".BootReceiver" to no avail.

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.

The receiver code is like below:

I ran the modified app, but I still see many log messages as below after the phone wento sleep (the screen was black):

This means the flag AlarmManager.RTC didn't work.
New to Android and this is probably a stupid question but I couldn't find an answer after searching the forums.
I have the Evo and cant figure out how to get rid of the completed download indicator arrows at the top of the screen.
I want to find the dimensions of the various views in my layout. My understanding is this can only be done after layout is completed since layout is somewhat dynamic. So, after the activity calls setContentView() and then returns control on the main thread to the OS so that layout can occur, how do I get a notification that layout has completed so I that I can query the views for their dimensions? On a related topic, can I find out the status bar's height or least the screen's full size (from which the status bar's height can be calculate by subtracting my window's height)?

After querying , when i call cursor.move To First(), the UI gets blocked until the operation is completed.This is very disturbing experience for user , especially if there are 10000 plus records.I use Thread.sleep in between after each 1000 records, As soon as cursor.move To First is called, UI blocks for 2 3 seconds. Am i missing anything here ?

View 9 Replies View RelatedI have two versions of the same application that starts by playing an mp3 from the res/raw/ directory, both versions of code are the same as far as the MediaPlayer is concerned and the code used. I get the following error in one version and it plays just I would expect in the other version. I am using 1.5 as my target. I get the same issue on my the devices (G1 and G2) as well as the emulator. I have read some other posts with the same issue and still am unable to resolve my own issue. For those who are going to come back with use MediaPLayer.create (context, id) I can not as I want to control what is being played without creating new instances of the player. It perplexes me that the same code works in another version of the same app that has no change in the code (in fact the alternative app just has a reduced number of images in the drawable folder).
The error message also will occur if the file is not found by using mp.setDataSource("file");

View 5 Replies View RelatedI 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 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. :)
I can't figure out what is wrong with my custom boot animation. Between the graphics were not created by me they were taken from a lot of different places. Here's the animation Box.net | Simple On line Collaboration: On line File Storage, FTP Replacement, Team Workspaces ~ Free Version And the commands I'm using in terminal emulator are
su cp /sdcard/bootanimation.zip /data/local/reboot
but i just keep getting a black screen I've tried lots of different tweaks to the desk.text but nothing is working.
Okay so some of you have probably figured this out but since it took me so long and I finally ended up pulling apart the Jager .zip install file to figure it out, here's now you do it.
Go look at any tutorial you want for making a boot animation, I'm not going into those speciffics here.
Instead of putting your first animation pictures in the folder part0, put it in the folder 'android'
In desc.txt you need to change the second line from 'p 1 0 part0' to 'p 1 0 android' substituting your loop number and frame delay appropriately of course.
Now just make sure you push bootanimation.zip and android_audio.mp3 to /data/local (this is NOT on the SD card but you can push to it without superuser)
To check to make sure it's working, do adb shell and use the bootanimation command. You can get out of it with a control-c (the audio will play but the screen will probbaly still timeout so if it goes blank just hit the power button).
I have one issue with my Karbonn A30. After installing custom Boot animation,my phone is not playing animation and sound.(Neither original nor new one). When i boot my phone after showing logo it come to blank screen and then started to my home screen.

View 32 Replies View RelatedAny 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.
