Jan 11, 2010I have the giant clock/weather widget on my homescreen (the one that comes on the phone when you first get it and the one most people probably use). I have seen animations of this clock on the HTC site that show the digits flipping over. And you would think it would do that anyway based on the design. However, I noticed my doesn't really flip. The digits just change instantaneously. No flipping animation. Is this just mine or is that how it is? I was actually hoping it would flip because I always thought it looked neat.

Could you please share the best practices where to initiate the thread so that keeps running irrespective of the Activity is being shown and things to consider.

View 1 Replies View RelatedAndroid :: How Can I Stop A Thread In A Activity?
Dec 9, 2009My problem is: Activity A called Activity B, and in Activity B, it start a background thread to do some client-server work. But it maybe takes too much time. So i add a cancel button to call the stop() method to stop the thread, and call finish() to finish the Activity B and go back to Activity A. Although it is back to Activity A, the thread isn't stop immediately. Can i just call the finish() to go back to Activity A, and leave the thread to exit by itself? If it is not the right way, which is?

View 6 Replies View RelatedAndroid : Stop / Kill A Thread?
Apr 29, 2010I am basing my game off of the Lunar Lander demo.
The problem I am having is my game not restoring its last saved state when it comes back into focus.
When the game loses focus/quits it saves all the information to a Bundle correctly, then runs surfaceDestroyed() to shut down the thread.
When I restart the game, I thought onCreate(Bundle savedInstanceState) method was supposed to always start first, then restore the saved Bundle if it is not "Null". But because it sees that I have started/ created a thread last time, it jumps straight to surfaceCreated method.
The only thing I can think of is to find a way to get rid/destroy the thread so that it runs onCreate at the start. However the stop() and destroy() methods for threads have been depreciated. Is there anyway to do this? Or is there a better method of saving an instance of the game? code...
Android :: Avoid Background Thread Been Killed?
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 2 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 :: Droid App Crashes Due To Low Memory / Stop A Thread Before Completion?
Nov 11, 2010My application is basically a image viewer. It is opened from both camera and as a separate application.
I open the image viewer to view and edit the picture. Each edit operation is implemented using thread. If my application closes due to pressing the home button, the next time I open it with camera. It throws anr.
This doesn't always happen. Only when large edit operations or edit operations on large image files are done.
I get out of memory error, sometimes timeout.
I guess it s because the thread doesn't complete the edit operation when home is clicked. and it s still running on the background. so when i open it s unable to process it.
m I right?
If so what is the way to stop a thread before the completion?
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 49 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?

Jul 10, 2009My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler.This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.How can I handle the screen orientation change gracefully?
View 9 Replies View RelatedAndroid :: Stop Background Apps From Causing GC And Eating Up CPU
Nov 17, 2010In looking at some performance issues for a game I'm developing I came across some interesting facts. Although I've minimised GC caused by my app, other apps can still cause one. Also, during framerate drops in my game, I've noticed things like the weather service, email checked, etc. going nuts in the background. (This is on Android 1.6).
I don't really want to block incoming calls, i.e. go into flight mode, before the game starts. I think it's important for the game to be interrupted if there's an incoming call. However, while playing, I don't think people care about weather updates, email updates, texts, etc.
Is there an interface that will let me control what is "active" in the background and what should be "suspended"?
