Android :: Need To Create A Background Service That Listens For Actions
Aug 26, 2010
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.

Is it possible to pass user defined Intend actions?
That is instead of using predefined Intend actions like "ACTION_MAIN" can I create my own action and use it in my code?
If so how do I do that?
I have been surfing for this detail for long but dint find anything useful. Can any of u help me regarding this?

I'm in a trouble managing a spinner. I have a spinner with its adapter. I initialize the spinner with a list of values when starting my activity. Then I force the selected value to be the one used in the object that I manage.
Once the screen is initialized :
When the user selects a value in the spinner, according to the selected value, I may continue (or not) to another activity for let the user choose a complementary and necessary value.
If the user "cancels" this second activity, I want to rollback the spinner to its previous selected value, and cancel some actions made in the meantime.
If the user goes to the end of the second activity, everything is fine and I want juste to refresh the spinner display with the datas selected in the second activity (I overload the getView method in the adapter to do this).
Overall, I can easily do all of this, however, when I force the selected value in the spinner at the begining of my activity, or whene returning back from the second activity by "Cancel", the change value event is catched and the second activity is triggered (the user did not click anything at all).
How would you allow the second activity to be lauched only if the change of the selected value in the spinner is due to a manual action from the user, and prevent that same second activity to be launched when the value of spinner is changed "in the code "?
I tried many solutions, as setting a boolean into the adapter that tells if the next event will be raised because of an "in the code" action.
Or also putting a boolean in the adapter that tells if the adapter has initialised itself, and I force that boolean to true on the forst change catched event.

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 want to call a method every X minutes, if my method got a result it ´should inform the user by vibrating or showing a alertbox. if the method doesn't get a result it should wait for X minutes and restart. What is important, this should also work when the phone turns to sleep. Which means I want to wake the phone from sleep to run my method. Actualy I can activate my method via a Button, and it is working like I want it to be except the background loop thing.
I already searching for a solution here in the group or also on google but I think I don't got the right search terms to find a solution for my problme. I already read about the AlarmManager and broadcast receiver but I'm not sure if this is right for my problem.

what is a good way to signal an error from a thread that is not the UI thread and you don't know which activity/handler is currently active? Can I somehow get eleto the current UI thread? Can I somehow use the MainLooper from the application context? I use notification for serious events where the user needs to take action, e.g. a login failed, but here I am looking for a transient notification with a toast and it would be ok if the toast is not seen in some cases.

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.

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.
