I have a background service component which is reacting to changes in network connectivity. I would like to alert the user that a a connectivity change event has occurred by popping up a Toast View on the device screen. Is this possible ? Can it be done even though a Service component does not have a UI associated with it ?

I have a service running in the background.I have a background thread that gets a reference to the service from the application's main activity. But when the background thread calls a method in the service to display a toast, I get the "Looper not initialized exception".Why,if I have a valid, bound reference to a Service, does this still happen?

Why existing solution will not work? All the solution provided in the link works well with an Activity, but I want to write a Background Service which controls the brightness of the screen.
Does anyone know what this program is? What does it do? i launch it, it goes into preparing device and then I am back at home screen.

I am developing my first Android App and I need a ProgressDialog to be showed while a background task, in this case just a http call on the server, happens.
I did a bit of studying on this and also have already checked other threads related to this subject.

Among others.
Than I got to write a bit of code:
1) In My Activity I declare a variable to be of type ProgressDialog
code:............
2) I have also written an inner class to extend AsyncTask as required, here in the doInBackGround is where I call a static method which actually do the POST http request to the server, in the server side I have blocked the server response 20s to validate the progress dialog.
code:............
3) When the button is pressed I than build the ProgressDialog anc call the AsyncTask I have created:
code:...................
Well, this is it, I believe this was suppose to show a progress dialog while the AsyncTask would query the server in background, but what I get is NO progress bar until server response arrives and than for a fraction of time(less than 1 second) the progress shows and the next Activity is called.
1)Which is better for developing a game.
a)Using XML layouts
b)Using Custom layouts with Surface view
2) while making a custom view using Surface view... do we need to have a secondary thread to implement the surfaceholder.callback()......
My code below does not show the activity in grey background as i have coded... do i need to use the unlockcanvas and all ,,but i havent used the secondary thread

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.

View 8 Replies View RelatedAn 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?

View 2 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 am trying to call a push notification background service from BroadcastReceiver class, but my application crashes.When I call this service through an Activity it's working, but my goal is to call this service from a BroadcastReceiver.
View 2 Replies View RelatedI'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?
