My application after an update needs to fill its ContentProvider with some data found on the server.
I found that starting a service from the ContentProvider.onCreate() method works but I'm not sure if it is a good idea or if it works randomly.
I don't know the initialization of an application in android. Are the services always already available before the content provider is created?

What is the lifetime of a ContentProvider in Android? After onCreate() is invoked, will the ContentProvider persist unconditionally for the lifetime of the process?
My ContentProvider manages a list of records, but only 1 is designated "active" and will be accessed by different applications a lot. I was wondering if it's safe to cache the index of this active record in memory as a member of my ContentProvider to speed up lookup.
Why if I start the MPlayer from the onCreate it doesn't start?
I tried also from onStart(), but the only working way was from onTouch or on key press.
Any idea how to start it without any additional user input needed?
I want to know what es the best place in an Activity to bind to a service? I saw examples doing it in onResume() and also in onCreate(). I was asking myself if it is not a problem putting it into onCreate(), cause in onPause() i will do a unbind to the service, so i dont get a serviceConnectionLeak, if i leave the activity. Now if i press the Home-Button and then switching to the HomeScreen, the Activity will unbind from the service, when i go back to the Activity from the Taskmanager, then onCreate() will not be called and if the Code is trying to access a function from the service i will get a null-pointer exception. If i bind and unbind only in onResume() and onPause() i dont have this problem.

Currently, it is taking about 20+ mins and for this time my UI is stuck. I was thinking of using a thread in service so my UI doesn't get stuck but it is giving error.

How do i check its presence and bring it to front, or optionally start this.
From what I can gather from other posts, this is about what I need to do:
CODE:..............
I don't knwo which of thest flags pertain to what I need to do. The docs are quite merky, and my random attempt at making this work failed.
My application has a background process which continuously waits on a socket for receiving messages and it should be started only once and at the time of application starting.Thus i want to do that background job in a service.
The service should not be started from the activity ,it should be started at the application starting.
How can i define the service,which will be started at the time of application starting?
If at all the service is started from activity.The activity can be destroyed and restarted.when this happens the service also be restarted .
We have a service. bindService() returns true. But our ServiceConnection is never called with onConnect(). The onCreate() of the service is never executed (neither is the onBind(), of course).
Except sometimes! (twice now, out of many many tries).
Remote service, local service, intent-filter, direct class invocation, "procedure" attribute, no procedure attribute, cupcake, 1.1, emulator, device ... we've tried 'em all!
We belive the service is found, and in the remote case, we see the new process always created ... but the dang service just isn't started. We aren't specifying any security settings and writing the simplest manifest entry we can....
I am trying to start a service from the BroadcastReceiver, but I keep getting the startService line marked as an error:

I am having service inside a .apk file. I want to automatically start this service when this package is downloaded from the browser and installed. Is it possible to automatically start the service when the .apk file gets installed using some special intents.
I am right now using activity and broadcast recievers to start the service . But however, I would like to start the service automatically when the apk file gets installed with out writting activity or broadcast recievers.
My service is not in the same package namespace as my application / activities.
I have
CODE:...........
The issue is that my service is in -- package com.myco.service.myservice and my activity is in -- package com.myco.test.myactivity
My questions are:
1. does my service *have* to be in the com.myco.test namespace?
2. if it doesn't, how do I specify the android:name for my activity and my service to work?
I have moved some intensive processing from my main thread to a service. My UI is hanging and then crashing when I start the service, even if I put the service start in a new thread started via
Thread updateThread = new Thread(null, backgroundRefresh2, "new_thread"); updateThread.start();
What am I doing wrong? Also, it seems like the cause of the eventual crash in the service/worker thread doesn't show up in LogCat.
Is it possible to start a service directly from the launcher by clicking the application icon?
I have no activity just a single service which I want to start when I click on the icon, however when I specify my service's intent-filters it seems that it will not be recognised from the launcher, therefore no icon is visible in android's launcher.

I have a Service which needs to receive data from external packages. So, to locate the data providing external packages, I use activity- filter and PackageManager.queryIntentActivities function to locate the interesting packages. Now, from each such package, I need to get a ContentProvider URI. So I want to start the external Activity and the external activity will return a result to my service - something like "startActivityForResult". The problem is that there is no way to call "startActivityForResult" from a Service, only Activity can do that, and my project does not have any Activity, and probably can't show UI for the user.
The bottom line: Can anyone suggest a way to get ContentProvider URI from an external package, while my package has only a Service?

View 3 Replies View RelatedI have an app which runs as a background service only. I'l like it to start up when its installed. As its just a background service it doesnt show up on the pane of installed apps. So there is no way for the user to manually start it. I've already regietered for the BOOT_COMPLETED intent which works but I dont want the user to have to power off the phone after the app has been installed, just so as they can start it.
I've looked at the following intents: ACTION_PACKAGE_ADDED/CHANGED/ REPLACED/RESTARTED/INSTALL, ACTION_SCREEN_ON/OFF, ACTION_USER_PRESENT, ACTION_TIME_TICK,
But it doesnt seem that you can register to listen for them from my manifest.
How I can start my background service without a power off/on?
I have written a class which extends the Service class of android and would like to launch the service during device boot-up. From the service I would like to receive the intents such as boot completed and screen off and on. Currently I am using a BroadcastReceiver to get the boot completed intent and then on starting a service to receive screen on and off intents. But I would like to remove either the broadcast receiver or the service. Any inputs.
