I am trying to get this code to run, but I get an IllegalStateException when I run this code saying that the content of the listview wasn't notified, yet I have a notification upon updating the data. This is a custom listview adapter.
Here is the relevant part of my code:

In my application, sometimes the following exception is thrown:

It's difficult to find the error, because in the stacktrace none of my methods is listed. So, does anyone know when this exception is thrown?
After http://groups.google.com/group/android-developers/browse_frm/thread/1... I am using

Using com.example.android.notepad and ExpandableList2.java from com.example.android.apis.view, I have written a simple application that contains a content provider serving two tables in an sqlite database and a display activity that uses my ExpandableListActivity subclass. I am using my own layouts for the ExpandableList, and the group and child layouts. The contents of the database are being displayed properly in the display activity, and the groups collapse and expand fine. However, if I expand a group, and click on a child to select it, I get the following stack dump:

I've yet to be able to set a breakpoint in my code that is reached before the IllegalStateException gets thrown. Looks to me that I'm doing what the examples do, but apparently there is something I'm missing.
I have a very simple application. There is a refresh button, everytime it is being clicked, the adapter will call notifyDataSetChanged() to update a ListView. However, I got IllegalStateException all the time.

I found a error that I dind't know about, Iam using a List, when Iam scrolling down to the bottom of the list it thows an error, why does this occur? Iamgeting the items from a service, and everything looks fine inte listview.

I've managed to show existing user in a textview. But it can only show one at a time so I decided to use listview.

But I received this error message from the logcat.

I have added listview in listview.xml. I do not understand why the error msg tells me that.
For my xml, I got two xml file to make the listview work. First is listview.xml and second is adminmain.xml. For listview.xml, i've placed only listview. And for adminmain.xml, I placed textview.

Im trying to display this listview, but I keep getting a: 07-17 21:14:22.233: ERROR/AndroidRuntime(349): java.lang.NullPointerException
I think I know what the problem is but I dont know how to fix it.
I have a String array which I will be using to be displayed in my list
CODE:.....
Dont worry the parser works great. the only problem I see with it is that the parser doesnt know how many strings the website will have so I am setting the String array in the parser to be very big: String substr[] = new String[250];
But I know that mostly there are only like 11 to 13 values that I will be storing in that array, the problem I think is when i do this:
CODE:..............
Since the String array is set to have up to 250 values in it and I only actually store say 12 then there are a null entries so when I run the code it shows me my list view, but when I get to the bottom of the view it force closes and the log tells me that there was nullpointer. I can tell how many entries I collected while I am parsing, but how do I tell my listview to only show say 12 items in the list so there wont be any null entries. or is there any other solution for my problem.

I saw Mark M. example (http://www.androidguys.com/2008/07/28/fancy- listviews-part-five/ ) and test it. This is really good. But i have one problem: After i start the app, i want to see my GUI (one Tab content is a ListView, the second and last Tab is a MapView). In a background thread, i want (and i can) load the data for the listView. So i first create the Tab with the ListView without any content (my string array is empty: String [] array = {""}; ). Now if the background thread is ready and the array-String has get the data, i want to update the ListView in my tab. I try: my_adapter.notifyDataSetChanged(); but without success. What must i do, that the ListView gets updated.

View 1 Replies View RelatedI have a problem with adding new items to ListView.
I use custom adapter MyListAdapter. I do that way:
CODE:...................
I have a listview of items (songs on the sd card). The user has an option to load all the songs on the sd card to into a current playlist -- those songs are what is displayed in the listview. Because this can take few seconds to load if they have a lot of songs on the card, I want to display a progress dialog to just tell the user "One moment..." until the list refresh is done.
I launch a thread to do this. I've done this successfully on another app I have (which just updates a database in the background but doesn't update any display), but this one fails with this error message, "Can't create handler inside thread that has not called Looper.prepare()". I chopped down the activity and pasted it below. What am I doing wrong here? I have just a vague idea of what might be happening.
By the way, everything works when I take out the threaded stuff, it just looks like the app freezes for a couple seconds.
code:..............
I never got this working in a straightforward manner. Sorry if I'm being a little vague. I'll try to elaborate on what I'm trying to do. I am trying to build a listview that grabs its data from a webservice. Once I initialize a listview, I want to keep polling the webserver periodically and update the contents of the listview. For this I am doing something like this:
public class SampleAutoUpdateList extends Activity {
//Autoupdate handler
private Handler handler = new Handler();
private Runnable updater = new Runnable() {
public void run() {
/*
* Update the list
*/..................................
CODE:........
My array clearly has been updated, and I can see the change when my app starts, but why doesn't it update in this method? The code enters this method.
I have list of items ion my activity which I load dynamically, item after item. Initially I load "lightweight" version and when processing is done I want to update the item with new information. Like set some text or replace an image. That means I need to update what ListView item is displaying after Adapter#getView already returns. Of course I don't know if user is actively scrolling and this item is still visible or has been scrolled out ot view. The only thing I can think of is to extend View so it performs some operations on it's own thread and updates itself when done,but will it work?

Several People write I should use notifyDataSetChanged(). But I can not place this Command in my Thread (just unknown).
I have a ListView backed by a custom adapter based on a CursorAdapter.The cursor I give it is based on a list of Notes in the database (each note is a DB row).Everything works just fine until I delete a note from the database. I'm not sure how to properly update the cursor/adapter/listview to display the new data.I've read conflicting posts on using adapter.notifyDataSetChanged() vs cursor.requery() to refresh the UI, but neither of them seems to work in this case.The only way I've been able to refresh it is by creating a new cursor from a new query and calling adapter.changeCursor(newCursor).Could someone demonstrate the proper way to update the backing data and then the UI (with psuedocode if possible).
View 2 Replies View Related I am at my wits end with this android app I'm making. Basically, it populates a listview, each row containing 3 values that will be updated at a specified interval. The values are blank on startup but are initialised after the first run through the code.
However, every other time the listview wont rewrite itself! Logcat tells me the updated values are being passed in but the adapter won't update.
Code:
adapter = new snmpAdapterView(this, parsedObjects);
setListAdapter(adapter);[code].....
i recently update to 2.2 and encounter two problems: problem 1: My app stop working. First I thought is the changes I made, but after reverting to the last revision the app is still crashing. The app is targeted for 1.5 and it crash when I press the "menu" button with the following stack trace: Thread [<3> main] (Suspended (exception IndexOutOfBoundsException)) ViewRoot.deliverKeyEventToViewHierarchy(KeyEvent, boolean) line: 2244 ViewRoot.handleFinishedEvent(int, boolean) line: 2158 ViewRoot.handleMessage(Message) line: 1490 ViewRoot (Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 3948 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object) line: 521 ZygoteInit$MethodAndArgsCaller.run() line: 782 ZygoteInit. main (String []) line: 540 NativeStart.main(String[]) line: not available [native method] I do have onCreate Options Menu and onOptionsItemSelected implemented but the execution never reach my code. I tried to uninstall the app, install it again, delete the device and created again - no luck. I tried to rebuild the project as well. That did not help, however lead to problem 2: I have two apps in the workspace. Every time when I launch Eclipse, both projects dont have any errors. However rebuilding all projects always results in build error in the second project: The project cannot be built until build path errors are resolved And this error will not go away unless I restart Eclipse. Ubuntu 10.4 Eclipse 3.5.2 Target platform Android 1.5 I'm new to Java/Android.

When we issued our first update for a paid app, it bombs the minute a user downloads, install and tries to run.New users have no problems.For awhile I thought it was something we were doing as developers, but I'm reading descriptions of very popular free games saying, "To upgrade uninstall and reinstall".The free developers have this luxury.For paid apps the purchaser can't request a refund after the second download.If this is a market issue we are f*#%ed.Please tell me the magic way to get an upgrade out.Also, are developers testing this?

View 9 Replies View RelatedWhenever I go to my "Downloads" in the Market app, FeedSquares for Google Reader is trying to download an update. It is always unsuccessful. I uninstalled the app (using Uninstaller) and it's still on the "Downloads" screen. If I look up FeedSquares in the Market app and select it, "Cancel Download" is my only option. If I select that, the Market app crashes with "The application Market (process com.android.vending) has stopped unexpectedly. Please try again."I've tried everything I can think of, including a reboot. At this point, I don't care if it gets deleted, reinstalled, etc, as long as it gets off of my Downloads screen. Anyone have any ideas?
View 2 Replies View RelatedI uploaded the new updates to the application in the market. There was no error message shown. It seemed that the uploading was successful. However, the version name and the app itself were still the old version. FYI: lost the original private key or the keystore file. I generated a new keystore file to sign the app. I also met the minSDK problem and solved it by set the minSDKversion in the manifest file. There must be a way to update the app. I don't want to upload the app as an new application since there is a large base of existing customers.
A few minutes ago I have updated my Samsung Galaxy with the "New PC Studio" for Germany (not Android 1.6!!!). After that, my mobile restarted and now the whole system isnīt working. There always appers an error message that process com.android.phone has stopped unexpectedly. Normaly( when I bought this phone ) I was able to tap to Wait, but now there is no way to do it. Now I can only tap to close but then it cuttes all my conections. This wouldnīt be the problem if it appeared only one time, but THE ERROR MESSAGE APPEARS EVERY 5 SECONDS.

My app has been working quite well for some time, and I just tried to update the SDK and DDMS to 0.9.9, and now it won't build.
I've done a search for the CharBuffer class and don't find any matches in my files, but I am using several API's (BUMP, C2DM, Admob). I definitely don't use any of the core-library in my code. If the error message is correct, I just can't quite figure out how to tell which API is the problem without almost wiping out my code base, or starting a new project and copying a few files at a time.
Oh... but the two files at the bottom of the file are missing android-6sdk.properties and android-5sdk.properties. Anyone know where I find them?
I have tried uninstalling and reinstalling but so far, no joy :).
CODE:.........................
In something other than a core library. It is likely that you have attempted to include in an application the core library (or a part thereof) from a desktop virtual machine. This will most assuredly not work. At a minimum, it jeopardizes the compatibility of your app with future versions of the platform. It is also often of questionable legality.
If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine distribution, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message.
If you go ahead and use "--core-library" but are in fact building an application, then be forewarned that your application will still fail to build or run, at some point. Please be prepared for angry customers who find, for example, that your application ceases to function once they upgrade their operating system. You will be to blame for this problem.
If you are legitimately using some code that happens to be in a core package, then the easiest safe alternative you have is to repackage that code. That is, move the classes in question into your own package namespace. This means that they will never be in conflict with core system classes. If you find that you cannot do this, then that is an indication that the path you are on will ultimately lead to pain, suffering, grief, and lamentation.

I own an xperia mini pro and I can replicate the issue always now. When I get an incoming call while the screen is off, if you slide out the keyboard (without opening the screen lock), immediately I get a Force close error for com.android.phone. I have Lookout Mobile security along with SayMyName installed. I have tried removing both, but the problem does not seem to go off. I am using Zeam as my home screen. On FC, SayMyName continues to call out the caller (or number if its not recognized), but the phone application crashes and on closing the FC pop up, the GSM mobile connection reinitiates (I am not in 3G).
Its just like when you switch on the phone after a shutdown. I have even tried changing home screen (ADW same problem), but seems like this issue persists. The problem is I keep my phone in a pouch attached to my belt and when I get a call, many times while bringing out the phone, the sliding of the keyboard happens and I get an FC. Then, there is no way to make out who had called and its very irritating (the call log does not register the call due to the FC).
I've recently updated my Hero to 2.1 from 1.5 and all is good so far apart from whenever I try to sms my contacts I get a message saying that I cannot send an mms to more than 10 recipients which is a real pain, however these are not mms' but sms' I've searched in the settings menu but I cant find a setting to change can anyone help me please?
