How do I make my service always alive?? If my service gets killed because of an exception or if the VM kills my service on low memory, How do I make sure that my service is always running?

Is it possible to keep service alive even if the foreground app does not run anymore? My app consists of a foreground app (UI) and a service that should keep running in the background until it is being explicitly stopped by the user (similar to a music player). The problem is that if the user opens other apps, my foreground app is being killed by the system (makes sense) but then also the service is being killed by the system (does not make sense).

What is the recommended way to handle these changes in an activity that binds / unbinds to a service (that is possibly heavy/slow to start)? When the activity gets destroyed, it unbinds & causes the service to be destroyed. When the new activity is created, it binds & recreates the service.
The only choices seem to be:
-- override onConfigurationChanged in the activity. Feels ok, but non - conformant.
-- explicitly start the service & only stop it when the last activity gets an onDestroy that's not due to a config change (i.e., there was no call to onRetainNonConfigurationInstance). Feels icky.
-- explicitly start the service & don't stop it until some amount of time after the last unbind. Ickier.
On a related note, what happens between activity switches within a process, where the first activity (A) starts the next activity (B) & then calls finish() -- is there a guarantee that B.onCreate is called before A.onDestroy? If not, and the activities share a service, the same issue of keeping the service alive during this window exists, but with only the icky workarounds.
Once we call the startService() method, can we keep the service alive until its explicitly stopped by the user? I want my service to stay alive until the phone is switched off. How can i do this? The idea is that when I receive an incoming call, I want to start recording and once the status changes to idle, I want to stop the recording. I am doing this inside my service. It does work sometimes and sometimes it doesn't. How can I implement such a thing in a service? Can someone help me with this?
View 2 Replies View RelatedThe app widget documentation indicates that the "widget provider"being a receiver of a broadcast service may not exist (the process) beyond the completion of the call.If I want to maintain state between two broadcast events, such as say widgetProvider.onUpdate(), can I start a local service and leave it hanging there until my widgets are disabled? If I didn't explicitly stop that service will it be loaded again and resumed when the device wakes up.
View 4 Replies View RelatedI am currently firing an Intent to a Broadcast Receiver which in turns starts an Activity.
Then from the same Service another Intent is fired to a Broadcast Receiver thats in the Activity.
The problem is that the Activity isn't getting the Intent meant for it because it is fired before it is alive and the Broadcast Reciever is registered.
I was wondering is there anyway to make sure an Activity is alive before sending an Intent?
How do some android app make their service restart even if killed from task manager? A good example is Lookout security app. What I guess is that it has registered for all common events that are announced like app installed unistalled, interenet available ,etc.Is this a way to keep your service running ?Another solution I found was to make 2 services monitoring each other, so if one gets killed restart another.Which one would be a proper approach? Is there any way in android to start booting automatically(if device is switched off) once connected to power source? I have never heard this on mobile platform.This is possible for PC through bios feature. Can it be done on android?

This will start the service but when i exit the activity by invoking finish() and system.exit(), I see that service created/started by the activity is also terminated.How can i make sure service runs indefinitely even after terminating activity that started the service?

View 5 Replies View RelatedI have an app which declares a BroadcastReceiver, the receiver gets the broadcast, does what it needs to, then ends ensuring that everything is tidied up as needed. When I examine the system through the DDMS view in Eclipse the process for the application is still running after the receiver has completed. I've even boiled it down to a simple test case which gets a shared preferences instance from the context, checks a random setting, and then exits, and, when run on the 1.5 emulator (which is the minimum supported OS level) the process is still hanging around.The reason this is an issue is memory usage (which shows under DDMS as around 2MB).I've had queries about why the application still uses up memory even when it's not doing anything, so, my question is; Is this behaviour normal, or have I missed something that would make the process exit?
View 9 Replies View RelatedI just wondered which frequency is OK to send whitespace keep alive packets onto a TCP connection to keep it alive on a T-Mobile 3G connectivity (the use case is to maintain an idle XMPP session alive). On SFR in France, we are disconnected if idle for 3 minutes, but I guess T-Mobile's timeout is lower. By the way there is a bug in the Smack library, the "keep alive" setting is not enforced, e.g. if you set it to 30s, in the worst case the whitespace will not be sent until the double of this time (60s).

View 9 Replies View Relatedam developing an app that needs to track incoming calls. I have set up a phonelistener which is launched form a service like so
TelephonyManager tm = (TelephonyManager)getSystemService (TELEPHONY_SERVICE); tm.listen(mPhoneListener, PhoneStateListener.LISTEN_NONE);
This seems to work for a while but then fails to fire after - say an hour. I have tried relaunching the listening in a timertask every 60 seconds but this does not seem to work. Is there a way of keeping a listener alive for a long period of time. I can only assume the system is garbage collecting it.
I want my service keeps network connection alive even if user presses the power button to shutdown the screen. As I have tested, socket will return exceptions and through CONNECTIVITY_ACTION intent, i know EXTRA_NO_CONNECTIVITY is true. So can current Android keep connection not closed when screen is off?
View 3 Replies View RelatedTrying to understand the Android framework model. I have an application that needs to have several threads running. On thread gets GPS fixes, another picks up GPS fixes and pushes them to server, and yet another occasionally polls a server for dispatched orders. Some of these threads update status Views as well.
Since I am new to Android, the application framework model hasn't clicked for me. Where are these threads started? Right now I start the threads in the initial Activity, but if I understand it right, once that Activity goes invisible it is stopped. Furthermore, I have to track GPS and network statistics so that I can have a View which may (or may not) be the active View.
Is there a way to keep an Activity in memory after the user hits the back button on it?ActivitySearch is used frequently in my app, however after the user starts it up, then hits the back button, it's destroyed, and the next visit to it requires it be built from scratch again.If after its first construction, I could just request it be paused instead of destroyed on the back button, then I could reuse it. Is there a sensible way of doing this?The only way I could think of reasonably doing it is to combine ActivitySearch with ActivityMainMenu into a single activity, and simply switch views when the user chooses search, but this is probably a bad design.

Update
The reason in this case is to keep the video streaming from the phone to a server.
I had a weird issue that has sprung up twice now with making phone calls and I wanted to see if anyone else was experiencing the same thing. Visually everything looks like it is functional with my phone service on the phone. I have bars, nothing out of the ordinary. However, I can't make any outbound calls either through my contacts or by manually dialing. I the number pad and it makes the response noise but doesn't actually type the number. In contacts, I hit call and the same thing happens. The fix I have found is just to soft boot the phone. Now I hear you all saying "No big deal, just restart." Yeah, it is no big deal unless I have to make a call in an emergency say calling 911 or things of that nature. Waiting for 5 minutes for my phone to reboot in an emergency can cost lives. I know I am being a little dramatic, but c'mon, at the end of the day, it is a phone and it is having trouble making calls.
