Is this possible in Android, anybody having suggestions plz welcome. There is provision of Notification Manager for icon, but it is not reacting to user events. Is there any other way to this.

I wish to have one application that runs in the background, which knows when any of the built-in applications (messaging, contacts, etc) is running. So my questions are: How I should run my application in the background. How my background application can know what the application currently running in the foreground is.

Service Component is used to do some task which can be done without user interaction. But for that we have to run a thread in subclass of the Service. I think we can create a thread in Activity class itself then what is the use of Service component? Why don't we create another thread and write the non interacting code in this thread.

I got a null pointer exception in an Activity onCreate() while trying to access my Application object (extended from android.app.Application).This exception occurred very rarely and i have no way to reproduce this again.My App starts a service on BOOT_COMPLETED intent and the null pointer exception seems to have occurred during boot up. Can somebody please throw some light on this issue? Application should have been created before creating any activities.

I am in the process of creating an app that is similar to the build-in SMS app. What I have tried: - running a regular service which worked just fine until android kills the service - using the AlarmManager the make the 5 min. interval call to a service. But I was not able to make this work.

I'm trying to develop a service, which needs to be run in background as a low priority task and does some complex processing . I need to gracefully quit my service when their is a resource shortage( like CPU running low on memory). Was there any APIs available to know the CPU resource usage, Objectives of my service is to - 1. Exit service when a high priority application(s) is running and which might need entire CPU resources. 2. Should store my states before onDestroy() of my service is called.

It seems trivial to use GPS in a background service, but how can you do the same with the accelerometer? Everything I've tried seems to require a context, but a background service doesn't have a context?

I wish to use implement Service in my application to display a message on the screen. This service should run while my application is running. But right now, i just want to test the service function and the Service doesn't seem to work well. In the main java file, i call startService(new Intent (this,testing.class)).

An activity can use AsyncTask or Handler framework for background work. Both will continue to work even after user has moved away from the activity that started them and the onDestroy for the activity has been called. In other words, an activity is fully capable of doing background work even after its GUI has been shutdown.In this scenario, use of Service for background work seems like redundancy. What does Service bring to the table that an activity can not do?

I 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'm writing an application that consists of a background Service and one or several Activities acting as UI towards this. There will most likely be several different UIs for this service that will installed later on, like custom widgets or UIs. The question is how to solve this in the most efficient way. Is it better to only use Intents for communication between UI and Service (sending control commands with Intents from the UI and listening for Intents from the Service for state and data updates) or should I prefer using IPC communication (AIDL -> Java Stub, binding to the service etc.)?
Since the UI might be started long after the service is started, I would either need to use sticky intents to signal current state, or have a very frequent intent sent by the service if choose to go with the Intent-based design. Which one would be the preferred way in that case? I've read that sticky intents are much more resource consuming than normal intents, but are intents more consuming than IPC directly towards the service? Also, is really an AIDL the right way to allow third-party integration? Intents sounds better, since they are also asynchronous.

I'd like to include a feature in my application that would include a running background service that would disable SMS, if certain conditions were met (location for instance). Is there a way I can intercept the user wanting to open any SMS app and block it? Would a Broadcast Receiver be able to do the trick? Maybe a different way to go about this?

I am currently writing my first Android application and I keep running into references to background and foreground services. Since I intend on using a service in my application I was hoping to get a clarification between the two and how they are used.

I've tried video recording in the background. But had failed.
Under normal circumstances, the recording works properly. However, if HOME key down-> Home screen or Other Activity is running, recording terminates.
In such a situation, I want to record continuously. I want to record whole process!

I am aware my issue is against the philosophy of Android, but I have no choice, this application will run on a embedded car gps and I need to bring an activity to prevent from car accident, for example, when it's happen around the user. I have to put other activity on the back and bring my alert pop up without user manipulation like notification on the front. Is there a way to bring manually an activity to the front, by resuming it like when you click on the android task switcher?

I am trying to create a simple Android application that has a ActivityList of information, when the application starts, I plan to start a Service that will be constantly calculating the data (it will be changing) and I want the ActivityList to be in sync with the data that the service is calculating for the life of the app. How can I set up my Activity to be listening to the Service? Is this the best way to approach this problem? For example, if you imagine a list of stock prices - the data would be being changed regularly and need to be in sync with the (in my case) Service that is calculating/fetching the data constantly.

How to find what service running on background on Android? Maybe I have to ask in another way? Does the service be presented as one "process", then we can use "ps" or "top" command to find it?

I'm new to the android platform, and I need to create a background service that listens for actions from different applications, the home activity, menu items in different apps, etc. Is it enought to call several event listeners and pass the different home activity events (and events from other activities) to the listeners? If so, what exactly to I pass to my event listener? Is the home activity an object that I can call? What is it and how do I pass it? Otherwise how to I listen for user interaction with variouse elements of a given view/activity? I need the listeners to trigger an activity that occurs before the event they asked for. For example. 1. They press the arrow button on the homescreen. Before it pops up, a picture pops up on the screen.

In Android, if I want to do some background work, what is the difference between
Creating a Service to do the work, and having the Activity start the Service VS. Creating a standard java class to do the work, and having the Activity create an object of the class and invoke methods, to do the work in separate thread.

I have an android main activity which starts a service (class extending service).
The services onStart creates a Mediaplayer and starts playing an mp3 file.
Then when you click something in my main layout (from the main activity), I call startActivity to fire another screen. I would assume my music background service keeps running, however it finishes. How can I achieve my goal then? code...
