Android :: Updating CursorAdapters?

Aug 31, 2010

When my Activity resumes, I query for a Cursor (by calling managedQuery to retrieve a Cursor pointing at my database using a ContentProvider), call startManagingCursor, instantiate a new CursorAdapter, and setListAdapter to my new CursorAdapter.

Suppose, at some later point, I launch some thread that hits a web service to query for new data to add to that table. Do I need to repeat everything I've listed above again?

Android :: CursorAdapters - ListViews And Background Threads

Aug 26, 2009

This application I've been working on has databases with multiple megabytes of data to sift through. A lot of the activities are just ListViews descending through various levels of data within the databases until we reach "documents", which is just HTML to be pulled from the DB(s) and displayed on the phone. The issue I am having is that some of these activities need to have the ability to search through the databases by capturing keystrokes and re-running the query with a "like %blah%" in it. This works reasonably quickly except when the user is first loading the data and when the user first enters a keystroke. I am using a ResourceCursorAdapter and I am generating the cursor in a background thread, but in order to do a listAdapter.changeCursor(), I have to use a Handler to post it to the main UI thread. This particular call is then freezing the UI thread just long enough to bring up the dreaded ANR dialog. I'm curious how I can offload this to a background thread totally so the user interface remains responsive and we don't have ANR dialogs popping up.

Just for full disclosure, I was originally returning an ArrayList of custom model objects and using an ArrayAdapter, but (understandably) the customer pointed out it was bad memory-manangement and I wasn't happy with the performance anyways. I'd really like to avoid a solution where I'm generating huge lists of objects and then doing a listAdapter.notifyDataSetChanged/Invalidated()

Here is the code in question:

Motorola Droid X :: Widgets Not Updating / Stop Updating

Jul 24, 2010

Anyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.

Android :: Way To See What Update Doing Before Updating An App?

Feb 24, 2010

Is there a way to see what an app developer is updating in an update BEFORE I update an application? I don't want to update my apps really unless I know what is being changed (i.e. a developer putting restrictions on an app that was once free).

Android :: Development And Updating The UI

Sep 19, 2010

I've just started with android development and updating the UI is really bugging me :/

This is what I've got working so far -

CODE:...........


It works fine but everybody says that doing your graphics in the main thread, so I'm trying (and failing) to pass it off to another thread. Trouble is, I have absolutely no idea how since really I've never used Threads.

The examples that Google gives on using Threads doesn't seem to be very clear and I couldn't really follow it for what I want to do. Could I ask somebody out here to give me the most basic example of how I could do what I'm doing here efficiently using Threads?

Android :: Updating The Call Log

Nov 13, 2010

I'm trying to update the CalLog to change the name/cached name of an entry. I have successfully updated a row but once i go into the call log on my phone the displayed name is removed after a short moment. I figured this is because the number of the incoming called is not found in any of the contacts. But why would it then clear the cached name that is in the Log? If the number is not in contacts the call log should display the cached name without trying to refresh it? At least that's the behavior I expect.My question is: Is it possible to add a name to an incoming number to display in the call log without adding the number and name to the contact list? I've figured it should be possible to add the contact first, then mark it as removed and thus get it displayed in the call log but that seems like a stupid work-around.

Android : Updating App Properly

Jul 31, 2010

I updated my android application on the market.This update included a change in the databaseHelper file where I put in more data and tables. Normally, when debugging, I would have to uninstall and reinstall the app because it doesn't see the new values in the database.Now, it's doing the same thing on the market.
Why is this happening?How can I fix this?Is it possible to 'rollback' the changes to the app?

Android : Need Self-Updating Package?

Feb 25, 2009

I'm looking for ideas on how to have a package that is not distributed through the Android Market (it's in closed Beta) upgrade itself.

I had hoped to download the .apk file from my web server and then use PackageManager.installPackage(), but that requires the INSTALL_PACKAGES permission, which is apparently not available to packages not installed in /system/app.

Best idea I have now is to launch an Intent to download the .apk (via web browser), but that would require the user to then manually install the package, which is unkind.

Android :: R Cannot Be Resolved - After Updating To 1.5 SDK Pre - Trying To Compile For 1.1

Apr 27, 2009

I updated to 1.5 SDK pre, together with the ADT. I followed the instruction to select Android 1.5 as target by right clicking on the project, Preferences>Android. In this window there are 3 options, Android 1.1 Android 1.5 Google APIs

I selected Android 1.5 and Apply, clicked OK. Application compiled nicely.

If I go back to the same Preferences and select Android 1.1, Apply, I can no longer compile my application successfully. I get hundreds of the same error R cannot be resolved

Then I try to open this project in another computer that I have not updated the SDK yet. I get the same error. I'm trapped until the new SDK is out.

Android :: Updating TextView Values

Apr 9, 2009

Hello everyone, and thanks in advance for the help. What I'm trying to do is a relatively simple task, but one that doesn't seem to be working. What I'm trying to do is display the Orientation X,Y,Z coordinates on the screen in basic TextView boxes. The sensors are constantly updating my Global.myOrientation float array, and then I'm running a Timed thread (I'm very new to threading, so forgive me if it's ugly, but it gets the job done almost). In this thread I just set the value of each TextView's text to the desired value. The problem is that it only seems to work the first time.

It correctly displays whatever my initial data is, but then subsequent runs of the thread do nothign to update the onscreen values when I change the orientation of the phone. LogCat output shows me that inside the run() method, the values of Global.getOrientationX,Y,Z are being updated correctly, and that the right data is being passed to TextView. How can I get around this limitation of TextView being initialized once and then immutable?

Any assistance in fixing this, or providing an alternate solution would be greatly appreciated. Code posted below:

Android :: Genie Widget Not Updating

Jun 24, 2010

2.1 OEM on Droid Incredible. It still says the temp from yesterday afternoon and stuck on the same news story. Tried re-adding widget and still nothing. Refresh does nothing. Also reinstalled yesterday because I was having the same problem and nothing. It's a great little widget, but if it doesn't update it's pointless for me. Had the same problem with the ESPN scorecenter widget. Would never load data correctly or wouldn't update. Made sure I'm not closing the widget in my task killer and still won't update.

Android :: Updating Widget In Emulator

May 4, 2010

I have a simple widget that sets up its appearance during the initial update.
This involves using RemoteViews:
updateViews.setImageViewResource(R.id..., R.drawable....);
updateViews.setViewVisibility(R.id..., View.....);

The widget's onUpdate method is the usual stuff:
for (int i = 0; i < N; i++) { int appWidgetId = appWidgetIds[i];
RemoteViews updateViews = buildUpdate(context);
appWidgetManager.updateAppWidget(appWidgetId, updateViews);
}

I have built a simple app that uses a Google MapActivity. On top of the Map, I have 2 overlays, a Marathon Course and the position of a runner. The latter position overlay simply shows an updated blue dot.I update the location of the dot every second but the screen does not refresh. If I tap the scrren then the dot updates. Am I missing some hard refresh call somewhere? My Overlay code is small and shown below. Note that it does go into the draw routine every second and the point is changed.

Android :: Updating Calendar Widget

Sep 28, 2010

I don't know if any of you use this already, but this is the most useful calendar app I've ever used. I can see this easily adapting to an Android widget, and think it would be very useful to many.

iCalViewer home page | Mac iCal calendar events and to do's on your desktop

It uses a timeline in order to see upcoming events. The vertical line is "now", and events in your calendar move across the screen towards the line the closer the events come to happening.

I already use this on my Mac, and would freaking LOVE it if someone stepped up to make something similar for Android.

Android :: ListView Not Updating After Filtering

Aug 5, 2010

I have a ListView (with setTextFilterEnabled(true)) and a custom adapter (extends ArrayAdapter) which I update from the main UI thread whenever a new item is added/inserted. Everything works fine at first--new items show up in the list immediately. However this stops the moment I try to filter the list.Filtering works, but I do it once and all of my succeeding attempts to modify the contents of the list (add, remove) don't display anymore. I used the Log to see if the adapter's list data gets updated properly, and it does, but it's no longer in sync with the ListView shown.

Android :: Updating AppWidgetProvider From Service

Jan 1, 2010

Here is my issue, I want to be able to update a specific AppWidgetProvider (home screen widget) from a custom service class. I have to build the remote view in the service because I'm also doing some networking in there, which takes some time. The problem is that I can't figure out how to update a specific widget (individual widgets can have different update intervals, using the alarm manager). If I wanted to do it from the onUpdate of the AppWidgetProvider I could just call appWidgetManager.updateAppWidget(appWidgetId, remoteView); Does anyone have any experience with this or any suggestions?
