I didn't found clear answer for why my code does not work. I assume it is because I am trying to update textview from runnable. Anybody know some workaround? Code isn't clean off course, I am happy to get that working so far as I am totally new in java.

I have looked at every discussion and thread I can find on getting this to work but it is not. I have a simple timer that updates a text view (mTimeTextField in the example below). The mUpdateTimeTask run method is being executed correctly (every second) but the UI/text field is not being updated.

I'm having hard times getting my GL thread (from GLSurfaceView) to trigger some code execution within the UI thread (from Activity). I tried it in every possible way (well not every, I missed at least the good one) none worked.
My idea was to get something called from the UI thread (to update some widgets) when the surface is effectively created. So I added to my onSurfaceCreated method the following call:
CODE:.............
This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:
CODE:.............
The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run () { [...] } };
In an existing Android project I've encountered the following piece of code (where I inserted the debugging litter) code...
with not a trace of the messages from the Runnable. So appearantly the Runnable doesn't run(), although img.post() returns true. Pulling the ImageView in onCreate() and declaring it final doesn't help.
I'm clueless. Simply setting the bitmap directly, while blocking the UI thread, does fix things, but I want to get things right. Does anybody understand what's going on here?

I developed one small application to display some text at defined intervals in the android emulator screen.I am using Handler class, small snippet from my code...
When i run this appication the text is displayed only one time.Please any one knows how to run a thread using Handler.
I want to send a broadcast from a new thread is start.
This is what i tried:

But ofcourse i need context..this won't work. How can i handle this.
I'm trying to do an insert to a DB as a result of a user clicking on a button. I want to do the actual insert in the background, so it seems I should use a Handler to do this. The SQLite insert method takes a Context parameter. My problem is how do I get a valid Context inside the Runnable that will do the insert?
View 4 Replies View RelatedI have an "open" animation and am using Handler.postDelayed(Runnable, delay) to trigger a "close" animation after a short delay. However, during the time between open and close, there is possibly another animation triggered by a click...my question is, how would I cancel the "close" animation in the handler?

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.

I am attempting to query a database and update information in the appwidget screen based on changes to the database done while in an activity so that when the user exits, the changes are reflected in the widget on the screen.The appwidget is being updated with a broadcast from OnPause() and OnStop() in my primary Activity.Relevant pieces of the code are below.The Toast shows me that the data is correctly being pulled when OnUpdate() is called.But the widget refused to change

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?
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.
View 3 Replies View RelatedWhen 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?
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?
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.
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.

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:

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.
