Android : Service Killed Unexpectedly - Phone Doesn't Lock The Notifications Are Generated
Nov 10, 2010
I have an Android service that's responsible for firing notifications at certain points in time. I use an android.OS.CountdownTimer for this. An activity creates and starts the service. If the phone is locked, notifications that are within let's say 1min are shown. Notifications that are much later are never shown. The service is unbound from the activity when the activity is onpause.
As long as the phone doesn't lock the notifications are generated, even if the activity is stopped and unbound from the service.
It seems to me that the service is stopped/killed. When I make the application debuggable and debug it on target, it works fine, also when the activity is stopped and the service is unbound.
The app is developed for v1.5 and runs at Galaxy S with 2.2.
Service is started as shown below
CODE:.................

I have a service in my app the creates an alarm and runs a check ever X minutes. I am new to android and I was wondering is there a way to prevent another app such as ATK (advanced task killer) from kill my service/alarms? It seems that if I normally close the app my alarms still work but when I go to ATK and stop the app the service dies as well. Maybe thats the point, but this service is rather important and most users would want it to run even if the app itself is no longer running. I assume that if the system kills it for whatever reason then their is nothing you can do about it. Could someone please inform me on this issue and a possible solution to do what I need?

I have a service running in the background. It starts on device boot. Also, I have one activity (that appears in the task launcher) in which I have provided buttons to start and stop the service.
Now, I install the application on the phone and I start the service using this activity (and not on-device boot). As expected the service starts and starts doing its designated task. I no-longer need the activity. So it goes out of sight and may not be required for a long time now.
My question is, now, if the android platform kills this activity, will it kill my service too ? (This is because I see that after few hours, my service is not running anymore.). If this is true, then will the service continue running longer if the service was started on device boot.

I have a service that needs to hold a persistent TCP connection, think IM. I'm reluctant to use setForeground() - the service being down temporarily isn't that big a deal, and I am assume I can trust that I'll be run again once memory is available, correct? The problem here is this. The service was started via startService() before being killed. However, when it is restarted, only onCreate() is executed. This makes it hard to continue, because starting work onCreate() means I can't even bind to the service (to say query it's status) without it doing so. Is this a bug or per design? What is the status of the service after it is being restarted? Is it consider "started" by the system, i.e. waiting for a call to stopService()?

It is very important that my service stay running until someone with a password stops the service from my UI screen. My app runs great but it is designed to be turned on/off by parents (with a password) on their kids phones. I have managed to make everything work but the problem I'm having is that if the kid uses a task manager to kill my service then my app is useless. I would be grateful to anyone who knows a way to either
1) monitor the service and start it back up automatically if its "killed"
or
2) prevent someone from being able to kill it except from the activity (administration screen) that launched the service. Or both?

I have a service that polls for data. To indicate this to the user I have a persistent notification in the statusbar. In some cases when the device goes low on memory it destroys the service but OnDestroy is not called. Later when there is available memory OnCreate is called. Is this normal behavior? I had hoped that OnDestroy would be called to I could remove the notification in the statusbar. Now the user thinks that the service is still running, while it has been stopped by the OS.
In order to restart the polling how do I know that the OnCreate is really a restart event and not first time creation of the service? I thought about checking for the presence of the notification in the statusbar, but I couldn't find a API to check if a notification was showing or not. I have not tried "SetForeground" on the service, since the service isn't that important to the user, but maybe that would minimize the problem.

I have an app widget that uses a Service to handle updates (as per the SDK sample). If a task killer kills the service, the widget obviously stops updating. Is there any way I can notify the widget that the service has been killed so it can attempt to restart it?

I just want to know how detect that the activity or service has been killed by the advanced task killer? I was expecting the onDestroy method to be called, but it doesnt!
My app starts the background service on boot. The activity is not started except from menu. But its name appears in the advanced task killer list. When I try to kill it, it doesnt call the onDestroy method neither the service's.

Is there a way to notify an activity/service of a force-close request right before it gets killed?
I mean when the user hits the force close button in Menu>Settings>Applications>Manage applications>app name>Force Close.

Recently, I installed FRG01B. I had no problems with it except for the fact that I couldn't get the phone to mute.
I noticed that there was a really cool version of FRG22 out by Liquid Frozen Yogurt 1.3 (FRG22).
I downloaded RSD Lite, SPRecovery_ESE81.sbf, and I downloaded the 64 bit drivers for the Droid. I am using Windows 7 Ultimate Edition 64bit. I got the files from this page: FRG01B.SBF for Droid courtesy of RootzWiki - Droid Releases - AllDroid Public Board - FRG01B.SBF for Droid courtesy of RootzWiki - Droid Releases - AllDroid Public Board - AllDroid.org > Home
Anyway, I installed RSD Lite and the drivers. I opened RSD Lite and opened the SPRecovery_ESE81.sbf file. I clicked show device, but nothing was showing up in the window, but below it said connected. I clicked START. After my phone rebooted, it's shot. No service, no battery life, and it keeps rebooting itself. What can I do! Someone please help! My Gmail address is chim777@gmail.com and I will be available for chat as well. I will keep checking this thread every few minutes. Someone please help as I have no clue what the hell I did. All I wanted to do was root my phone.

It used to lock whenever you pressed the end button andwhen you cliced end again, you had to slide the buttonto unlock it. But suddenly, it stoped doing it. So everytime I press end, it just goes right to the home screen.

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

I am trying to write an app that cannot be killed by a user or another application. I understand this goes against what Android has designed for its platform, this is more of a proof of concept. The plan is two have two apps, app1 and app2. When app1 starts it will start app2 and then bind onto app2, when app2 starts it will make sure app1 is started if not, then start it and bind onto app1. The point of app1 binding on app2 and app2 binding on app1 is so when one of them gets killed a method will be called that the binding has been disconnected and the app can then be restarted. I currently have the apps starting each other when they start up but I cannot seem to get them to restart when I force close one of them.
For App1 service I have and app2 very similar:
CODE:..............
And for my class that implements ServiceConnection I have:
CODE:............
I think the issue I am having is that onServiceDisconnected never gets called when app1 or app2 is killed. I think this may be because I am not correctly binding to a service.
W/JavaBinder( 884): ibinderForJavaObject: 0x436274a0 is not a Binder object
W/JavaBinder( 891): ibinderForJavaObject: 0x43621d30 is not a Binder object
How can I bind services together so when one gets force closed that I will get a notice on the other?

I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL.This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me?If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong.

This morning my alarm started unexpectedly at 6am. The lock screen turned into the snooze/stop screen. Dragging down didn't stop it it.. It came on every ten minutes for the next hour. My alarms were set to 9:45am and 8:30pm as usual. Even turning the phone off and on didn't stop the beeping. It was my 9:45am ringtone even. (The two are set differently)
Anyone else see anything like this? I'm on OTA 2.1

I was trying to root my samsng behold 2 earlier today using the command codes on theunlockr.com. I thought everything was going well as I went all the way to the last step where it rebooted my behold 2. Problem is, the phone kinda just turned off after doing the reboot command and didn't turn back on by itself (I gave it like 10 minutes). I eventually then just turned on the phone manually and noticed that everything was super laggy. Even when I used taskkiller to kill every task minus GDE, it said I only had 38MB ram available. I rebooted my phone a few times and it was laggy everytime so I decided to do a hard reset. The problem is that when I attempted the hard-reset, it will now get stuck on the samsung screen when trying to load up (stayed there for over 30 minutes). I can still enter the phone if I just start it up regularly without trying to hard-reset, but it will continue to be VERY laggy.
Is there anything I can do to restore this phone back to its original state? I was reading about using ODIN to flash it or something, but for some reason my computer doesn't detect my phone when I go into Download mode on startup (it does however detect the usb drivers on my phone once the phone officially startsup into its homepage).

I'm having an issue with inter-process communication with a Service and Notifications
The structure of my application is as follow: - ListActivity (TunnelDroid), once the user presses a listitem it will start a Service. The ListActivity is binded to the service for intra-process communication
- Service (TunnelManagerService): running in the background. This service will add a (permanent) Notification in the statusbar. Using a Handler I sometimes need to communicate with the ListActivity (to show GUI Dialogs)
- Notification: Once this notification is clicked it should open the ListActivity.
To add the action when the user touches the notification I use the following code: notificationIntent.setClassName("net.sourceforge.tunneldroid","net.sourceforge.tunneldroid.TunnelDroid"); Then I use the intent to create the notification.
Unfortunately a new Intent is opened. When I press the back button the original ListActivity is shown. So I have two instances of my same class/list.
How could I make sure the original ListActivity is opened when the user touches the Notification?
It's OK for me if the original ListActivity was previously destroyed, but I cannot have two instances. The problem is that the Handler in the Service has a reference to the ListActivity (PARENT_ACTIVITY), so if another instance is created I have invalid references. I could overwrite the PARENT_ACTIVITY, but then when the user presses the back button I have an instance with no correct link to my Service resulting in a crash/nullpointer.
The complete source can be found here: http://tunneldroid.svn.sourceforge.net/viewvc/tunneldroid/tunneldroid. Attached you can find a drawing of (most of the) inter-process communication. Could someone point me in the right direction?

I downloaded Voodoo (something) rebooted in recovery mode, and selected the file installed it and rebooted the phone. my phone turned on showing on the screen only Samsung and above it Vibrant. a voice on the phone told me "this will take 15 minutes." and that was it. the phone is now stuck on that opening screen and I can not get to download or recovery mode. It does charge if turned off and plugged in.

I have noticed that if my background service crashes the system will automatically restart the service after 5 seconds. This is great, but I have noticed that only the onCreate method gets called and not the onStart method. Does this mean the service is properly restarted or do I need to do something special in the onCreate method to make sure it is? I did have my initialisation logic in the onCreate method and my starting service logic in the onStart method but it looks like it will all have to be in the onCreate method.

This is confirmed by Verizon, so take warning.I got my Incredible on Tues, used my BB charger on my phone because the Verizon store said it was ok since it was still a micro usb. My battery started dying after about a few hours. Tried every trick in the book and still died afte about 3 hrs.Went to the Verizon store and got it replace. They once again said it was ok to use the blackberry charger. So i let the new battery run down as the guy said and began to charge w/ my blackberry car charger for about 30 min. I noticed the orange charger light was not on. I unplugged the charger and the phone will not even turn on now. Verizon is overnighting me another Incredible.Listen to others if you want or take your chances, but the tech guy at Verizons main tech support center said to use only Htc chargers. **SO USE YOUR BB CHARGERS ON YOUR INCREDIBLE AT YOUR OWN RISK**
