Android :: AppWidgetManager.updateAppWidget Refreshing Always Lagging One Behind
Oct 2, 2009
I've got an App Widget that gets updated (er... I try to update it) with the following chunk of code: ComponentName thisWidget = new ComponentName(context, MyAppWidgetProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(context); manager.updateAppWidget(thisWidget, remoteViews);
The problem I'm seeing is that it the user interface is updating always one behind (i.e. using the previous remoteView to update the user interface). So, i make that call with a certain configuration in remoteViews, and it doesn't reflect in the UI until the next time I call it with a different remoteView. I know this is kinda vague and I don't have a lot of details here, but i was wondering if I'm missing something very obvious.

I've successfully built a small sample app where the user can add a appwidget, using the AppWidgetPicker, using the action AppWidgetManager.ACTION_APPWIDGET_PICK. When I do this, the AppWidgetPicker takes care of binding my appwidget-id to a provider. However, now I'd like to load some widgets without using the AppWidgetPicker (for instance, maybe I want to restore the added appwidgets when I restart the application or something).
I've tried the following code
CODE:...........
But it fails with a SecurityException, even though I've added
CODE:....................
To my manifest file. Is this the way to do it? (using AppWidgetManager.bindAppWidgetId). Im using the emulator, and android 2.1.

I got the Droid from Verizon a couple days ago, and about two days ago I rooted it, and I'm now using Bugles Beast 0.9 with a 5 slot Chevy 1.2ghz kernel. I keep the CPU set to 800 because i feel like 1200ghz is burning up the battery unnecessarily when I'm playing games. However, I can't figure out why sometimes when I'm returning to the home screen, no icons will display for about 5 seconds (usually when exiting a program that eats up a large amount of CPU). Could it have something to do with Set CPU settings?

Why is support for OpenGL lagging so far behind with Android? I have ebooks that date OpenGL 1.0 ES back to 1997 or so. I don't understand why ~13 year old technology is what's being offered in the Android API. Could someone enlighten me? What's the best path for someone wanting to learn OpenGL ES 1.0? The ebooks I have are of course not oriented for Java/Android and most everything in them doesn't work when I try it. I can post some specific examples later but at this point I'm just wondering if I'm wasting time or if I should keep going and struggle through it. I have a tiny amount of OpenGL experience but it's with 2.0 and apparently things were very different back in the ES 1.0 world. I guess my question boils down to, is OpenGL ES 2.0 support coming to Android anytime soon? And what OpenGL ES 1.0 + Android learning resources already exist?

I'm gonna be honest here... When I found out that i could have GBA and SNES emulators on my android, I made up my mind. I tryed it out a bit on my friend's Motorola Flipout and was working just perfectly. However, on my own Flipout, the games are all "laggy". Not to mention the music which plays one note every 1 second or so... bummer. I know it's not the ROM, for i have tested with the same one my friend used... so I'm guessing it's a setting in either the phone or the emulator. Any adeas? ps: I'm using the free versions of the gameboid and snesoid

I have Galaxy W but I noticed that the games have a little lag. That normal maybe because my phone is not dual core. But I have read that lot of people are complaining about lagging in games even if they have a phone with good specifications like Galaxy S2 & S3. I understood that this is from bad optimization for Android, cause the games are direct port from iOS.

Im just asking why is my messaging app lagging like hell when my messages exceeds to like 150+ messages, I mean its kinda awkward since this phone has a quadcore processor and a 512ram. Is this some glitch on the os or just the dual sim or dual text to sim 1 or sim 2 making it lag so bad?

I'm trying to develop a small app, that can retrieve GPS coordinates, and store them, so I can retrace the path I took. The thing is, the GPS on Android emulator is kind of screwing around with my nerves... First of all, the Mock Position system doesn't work, so I'm manually fixing the coordinates with telnet "geo fix" command. Second of all, the location listener seems to not be refreshing. I'm lauching the app, fixing a first set of coordinates, and observing the response I expect. But when I push a second set of coordinates, the app simply doesn't react.
I tried a lot -big lot- of ideas on this, and I'm kind of running short...
By the way, I'm developping on Eclipse with ADT, and the SDK for Android 1.5 (French HTC Heros are still with Android 1.5) so that I can use my own app.
Here's my code (just the coordinate retrieval part) :
CODE:.................

I have a view with a spinner. The activity starts another acvitity with a popup where I add or delete values that the parent shows in the Spinner.
So, in onActivityResult() I refresh the content of the Spinner so that it reflects any additional or deleted values, by calling my fillSpinner() method.
The parameter to this method is the previously selected value:
CODE:..........
When I open the Spinner, it contains the correct list (i.e. it was refreshed) and the correct value is selected. However, the Spinner control itself (in its closed state) does not show the selected value, but the first in the list.
When I step through the code in the debugger, the Spinner value is correct before and after I call setSelection() (and it is always called with the same correct id). However, since I cannot step out of the event, when I resume the execution after a short moment the value in the Spinner changes.
In other words, the spinner's displayed string is changed and is different from the selected item when I return from my popup activity.

I have a listview that's populated by rows that get their data from a web server. It all works totally fine except I want to have a refresh button to re-download the data. I'm getting the data through an asynctask (getting the data in doinbackground) and then setting the listadapter in onpostexecute. All I do to run the asynctask which should take care of everything is run
new PopulateListTask().execute();
However, in my optionsSelect method, creating a new asynctask just like I did in oncreate doesn't do anything. It doesn't even enter doInBackground. I've tried using listView.invalidate() and listView.invalidateViews(). Is there some special way I'm supposed to repopulate a listview?
My only guess is that since I'm using a custom adapter, my getView method is creating some kind of error, but that wouldn't explain why it's not even entering my asynctask's doInBackground method. Thoughts?
Posting some code. This is a trimmed down version.
CODE:............
I'm getting this in my logcat when executing my asynctask the 2nd time. Any idea what it means? I tried googling to no avail.

I created an Activity which allows navigating between pages with a couple of Buttons (Previous and Next). When the user clicks one of the buttons, the Activity (same) needs to be "refreshed". In order to do this, I set up the buttons to make a call to onCreate(this); after they set up the other stuff that the activity uses for the paging to work. And it is working so far, but I'm wondering if there is a better way. Is there?

I have a TabActivity based class which has 3 tabs. All are ListActivities (but that's not important for this problem)
I'm updating the TabHost's TabSpec's to change the text on the tabs. This works fine and the ListActivities display correctly.
Iater on the execution flow I need to update the Text on the tabs from "Current Text" to "Current Text (3)", for example. I update the TabSpec.setIndicator() with the new text, and attempt to call invalidate() on the TabWidget (and all it's children). But the tab text refuses to update!

I used to get gmail email notifications instantly when they arrive now I get them only with 1-2 hours delay. Basically I get the notification of a new email faster than the browser version on my pc refreshes (dunno how often it does it maybe once every 10-20 secs). This has been going on for 2 days now. I will get the notification eventually of a new email if I don't mark them as read but just before it was within seconds now it's within hours of the new email arriving. The problem is gmail gets into sync loop I'm assuming this is a gmail problem.

I'm running into some issues here with my app. I have 4 tabs run through a tabActivity. One tab sends an intent and run my ListActivity that populates the screen from a simpleCursorAdapter. My problem is that when I change back to this tab, after the first time its run, the list never refreshes regardless of the changes made to the database via other tabs. Is there something I can call from onTabChanged to refresh my ListActivity?

In the Settings menu, there is an "Auto Refresh" option which you can set to "Never," but there is also a "Ticker Refresh" option which you can't turn off. What do each of these things control? Is the Auto Refresh just for when the app is running? Does it affect the widget at all?
Does the Ticker Refresh option only affect the widget? Does it have any effect if the widget is not being used on any homescreen?

My problem is when I want to refresh data in ExpandableListView while being in that current activity. I create adapter and when I want to add new data to list I call again constructor of that adapter(it is my private variable) with all new data....and then I call onContentChanged() method to redraw my list.
But what happens is that I cant expand my list any more...like it is blocked or something and logcat isn't saying anything...
This is the code that i call after setting new data in arraylists and maps:

I created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............

I'm trying to add views dynamically to a linearlayout. I see through getChildCount() that the views are added to the layout, but even calling invalidate() on the layout doesn't give me the childs showed up.

I have a Moto Droid 2.2 with "Alarm Clock Plus v2" set as my clock when in the multi-media dock. The weather information will load the current weather when the application first starts up, however will not refresh.
If I tap on the weather it will open the weather info with up to date info but going back to the clock will still show the old data. By removing the phone from the dock (thus exiting Alarm Clock Plus) and putting it back on the dock (thus running Alarm Clock Plus again) the weather info becomes current.
Has anyone else run into this? I looked in the settings for Alarm Clock Plus v2 and could not find any information on how often to refresh the weather info.

I have created an option menu which also has a sub menu. In the sub menu I have a setting for enabling/disabling images in my application based on the application level flag that i change based on the option being clicked.What I am observing is that when i click on the "Menu" and change the settings from enable Images to disable Images. its not reflecting.I have put the debug log and what have been seen is the onOptionCreateMenu method is getting called only one time- first time when i click the "Menu" button. That is the reason the changed sub menu is not getting reflected.My question is that is there a way i can re-create the option menu every time user presses the "Menu Button".

This Android application on Google uses the following method to refresh the database after replacing the database file with a backup:
CODE:...........
I did not build this app, and I am not sure what happens. I am trying to make this idea work in my own application, but the data appears to be cached by the views, and the app continues to show data from the database that was replaced, even after I call cleanup() and reopen the database. I have to terminate and restart the activity in order to see the new data.
I tried to call invalidate on my TabHost view, which pretty much contains everything. I thought that the views would redraw and refresh their underlying data, but this did also not have the expected result.
I ended up restarting the activity programmatically, which works, but this seems to be a drastic measure. Is there a better way?

I have set up Eclipse to run as smoothly as possible because I was having a lot of problems with it running out of memory in my last machine. One of the configurations was to have it automatically refresh the workspace every time I save. I don't know if that is the problem but I thought I's mention it. Here's a screenshot of the error:
It happens every time I open Eclipse and save anything. I was also having another problem with something to do with my workspace being compliant with Java 1.6 when I need 1.5. But then I switched and the problem went away. This problem then popped up. Does anyone know any solution to this because it is really getting annoying now.

This is a very common scenario: displaying images in a ListView which have to be downloaded from the internet.Right now I have a custom subclass of ArrayAdapter which I use for the ListView. In my getView() implementation of the ArrayAdapter, I spawn a separate thread to load an image. After the loading is done, it looks up the appropriate ImageView and sets the image with ImageView.setImageDrawable(). So the solution I used is kind of similar to this one: http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listviewThe problem I'm having is that as soon as I make the call to setImageDrawable() on the ImageView, the ListView somehow refreshes all currently visible rows in the list! This results in kind of an infinite loop. Code...

I'm trying to write code that draws accuracy circles around a gps location based on a time param. I have no problem setting up the GPS, or of calculating how to draw the circles.What's been killing me is that the Overlays always overwrite one another.So I can never have more than one circle.I've looked at all the examples and tutorials online but they seem to be obsessed with putting in icons or with Drawing from some database or array.If I understood correctly I should be able to do itemizedoverlays and just draw as i go without having to track each readout in an array.
