Android :: Way To Keep Service Alive Till Phone Switched Off?
Nov 23, 2010
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?

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).

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?

I am starting a service from an activity. Once the services starts, the calling activity loses focus and blocks till the service is completed. Why is this and is there a way around it to return the control to the calling activity while the service runs in the background?

The default way configuration changes (i.e., rotates) are handled is to destroy the activity & recreate it with a new one. 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.

The 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.

i last week took a HTC hero out on contract and switched from my iphone 3g, which i loved dearly reason being i wanted to use spotify to its full potential without having to shutdown etc.It's definately the best decision i ever took, i absolutely love the android platform and would recomend anyone else thinking of doing the same. A few question thought i have about the Hero;
1) battery life, seems pretty short? can i buy a better battery without having ot change the back cover? I like the idea of being able to carry a spare?
2)When on the internet/browser it always opens pages zoomed in, i find it pretty hard to use compared to the iphone, can i set it so that it open the page like a normal pc/iphone?
3)And how do i know i'm getting a 3g signal ?
4)Upgrade for Android? How do i get them? I read there is a better version but how do i upgrade it?

It's just that all my other Sony phones, the alarm worked (and calendar reminder) when the phone was switched off, to wake me up ect. Is there a way to activate this so that it will work, or does the phone have to be switched on to use this facility?

My Samsung Galaxy S Duos GT-S7562 is having many problems. First of all it is taking a lot more time to charge the battery and it gets very Hot while charging.
Wifi is also Disabled. I am not able to turn the Wifi on. And Phone is getting switched off Automatically. It won't even turn on until and unless I remove battery and insert it back. Tried to do Factory reset but no dice.

Firstly I am new to android so please forgive any ignorance below. My Questions are; I really need a phone upgrade (iphone 3g being a proper drag!) and the HD looks great, but with 3.0 scheduled (from what I have read) to come out around xmas I am tempted to hold off till then. Can anyone shed light on when the next HTC uberphone would be expected to come out? I can probably wait till Xmas before upgrading, and maybe a little longer, but otherwise I'll go for the HD in October.

I 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?

Is there anyway to block the UI Thread till the .mp3 file completes (or in general blocking UI thread till perticular action in the b/g thread completes).

I have read all I can about using the Inc overseas and am confused. If the phone is switched to WiFi in a WiFi spot, can you use the phone? I have read that Verizon put some sort of restrictions on it, but I'm not savvy enough to understand it all. My daughter is in the Coast Guard and we both have DInc's. She goes to places like Star Bucks in other countries that offers WiFi and we would LOVE to be able to text each other with our phones. Any advice would be greatly appreciated!

I 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).

am 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?

Trying 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.

If it is possible to keep an Air for Android application alive during sleep, how can it be done? I know how to prevent sleep and lock but this course is not preferable to some users.
Update
The reason in this case is to keep the video streaming from the phone to a server.
