Android :: Broadcast Message Leave Activity In Background
Oct 31, 2010My app's main activity listens to a broadcast message. When it receives the message it brings the activity to the front. I want to update the activity if it is in the front, so the user is playing with it, but otherwise I do not want to bring the activity to the front. How should I do it? Is there a flag for invoking the intent, or what?
View 4 Replies View RelatedAndroid : Kill The Currently Running Thread - If One Is Currently Running
Nov 4, 2010I've created a class which is an extension of Thread. This class hits a web service and throws some data on screen. I don't care about persisting this data (the screen displays search results).
Currently, the user simply types into an EditText and clicks a search button. I'd like to take away the search button and implement something similar to Google's Instant Search where, as you type, the search results get updated.
This means, as the user types, the search parameters change. I want to be able to kill the currently running thread (if one is currently running) and spawn a new one with the new search string. How can this be achieved? Can I do it with Thread or will I need to use a new object?

Mar 1, 2009As is mentioned above,What i'm trying is to protect a sub- thread,and keep it going on as long as the App that starts it is still alive.In other words,If the system need more resources,Let it kill both the App main thread and the sub-thread started from it,Instead of just kill the sub-thread.Is there any way i can do this ?? And another question here,The android system seems to be "rude",As it killed my thread without telling me,even in the logs,Is this the case?

View 3 Replies View RelatedAndroid :: Continuously Running Thread
Jul 20, 2010I am continuously running a thread in my activity which fetches lat/ lon information and the overlays on the map are updated dynamically through a handler. The overlays can be varying in number and can change dynamically. The thread is interrupted in onPause().
I am over riding the onTap() method in my Itemizedoverlay, where I want to call a dialog or may be start anothrer activity which describes that particular overlay item.
Every time I click on the moving overlay my app force closes.
I am basically using same onTap() method in http://developer.android.com/resources/tutorials/views/hello-mapview.... .
If it is only a Toast message and not starting a dialog/activity then it works fine.

View 1 Replies View RelatedAndroid :: Modifying Adapter Content From Background Thread
Sep 14, 2010I've read up quite a bit on the exception thrown while using BaseAdapter, but i can't seem to find an alternative solution: Make sure the content of your adapter is not modified from a background thread. What i want to achieve is to keep a copy of a message queue in memory, and use this message queue to populate the BaseAdapter for my ListView. The reason im doing this is that the message queue will keep getting messages from a socket even when the ListView is not currently present (for example a chat window).
The problem comes when i have the Activity with the ListView in foreground, BaseAdapter binded to the message queue's data, and a message comes in the socket. Adding the new message into the queue will throw the exception mentioned above. Unless i pre-populate my BaseAdapter with the message queue (as in the BaseAdapter having its own message queue) and updating both of them when a new message come in, i can't really find a way around this issue. I don't really want to double up the effort on keeping those 2 queues up-to-date like this, surely there is a better way of doing this? Send broadcasts around doesn't work either because of the potential delay in the adapter serving a scroll and the notifyDataSetChanged call is made.

Android :: Game Doesn't Work Due To Thread Background Processes
Mar 8, 2010I have written a very simple game with some simple animations, but I've noticed that when the phone checks email, or several other apps are running, the animations that update in my thread start behaving slowly or choppy. This is a problem as the game mechanic requires some careful timing of your screen touches based on the animations. So if it starts behaving erratically, the game doesn't really work well - and isn't much fun.
Is there a way to prevent this? Can my threads have a higher priority when they need to run?
Android :: Run Query On Background Thread On Cursoradapter Doesn't Get Called?
Jul 25, 2010I have a listactivity as a startup screen in my application. Which is displaying database records using custom cursor adapter. On create I set the filterable flag - getListView().setTextFilterEnabled(true)
My cursoradapter overrides runQueryOnBackgroundThread which runs corresponding query. The problem is that after typing some text and hitting enter, runQueryOnBackgroundThread never gets called. However, when the item click in the same view launches another activity(detail view of the record) and I come back to the original list activity, hitting back button, then text filtering works just fine. I don't call setTextFilterEnabled anywhere except during the initialization process and I can't really find any other API affecting this behavior, so any guesses why text filtering doesn't work initially, but all of the sudden starts working when I come back to the list activity from child activity?

Android :: Background Thread - Application To Sync Contacts Largest Number
Oct 18, 2010I am working on an application to sync contacts which are large in number. The syncing takes place in a background thread with user being able to browse through the rest of the application. I am displaying the sync status in the notification bar suing the progress bar. The problem I am facing is that there are instances when the activity is killed and hence the background thread used for syncing the contacts is purged.
View 1 Replies View RelatedAndroid :: ASync Task Progress Dialog Not Showing Until Background Thread Finishes
Apr 24, 2010I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?
