Oct 8, 2010I 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.
http://developer.android.com/reference/android/os/AsyncTask.html

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.

View 8 Replies View RelatedAndroid : Why Use Service For Background Tasks?
Nov 2, 2010An 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 RelatedAndroid :: Start Background Service On Install
Oct 22, 2010I 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?

View 2 Replies View RelatedAndroid :: Background Service - Intents For Communication Between UI
Jul 6, 2009I'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.
Android :: Running Background Service That Would Disable SMS
Jun 25, 2010I'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?

Aug 26, 2010I'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.
