Should I just have MyDataSetObserver catch the exception and move on? I'd like a more robust solution than that if possible. Or is there some other way I could rearrange my program so that the staleDataException doesn't occur (as often)? I believe that it is happening because I am launching the new activity in my onListItemClick.

I have activity A and I used managedQuery in Activity A. I have an adpater which extends from BaseAdapter. In GetView I access the mcursor to get fields.If I click a button on Activity A it goes to B, A---> B.The problem arises when I am in activity B *and it's visible(B), the error is thrown from Acitivity A.I dont understand why I get the error from Activity A. Activity B is visible now and A is in background.There was a post already on this group with similar error but there was no response.I was hoping if someone encountered this and found a solution.
View 2 Replies View Relatedi'm getting a "Finalizing a Cursor that has not been deactivated or closed" error on this piece of code. The code is used to fill a list view. Since it's a non-fatal error , there is no crash and all seems to works fine..but i don't like the error. If i close the cursor at the end of this code..the listview stay's empty.if i close the cursor in onStop, i get the same error.
View 4 Replies View RelatedMy application creates a database on the fly and also populates it. The problem is I get a "Attempt to Finalize Cursor That has not been closed" error in logcat which mainly refers to this function.
Code:
public static void populateFromDatabase(){
/* if the database is empty just throw in the question */
Cursor c = AppData.db.db.rawQuery("SELECT * FROM question", null);
if (c != null && c.getCount() == 0){
c.moveToFirst() ;
int count = 0 ;
while(!c.isAfterLast()){

My question is I am closing the cursor in all occasions so why this error ? Also note that i call this function only once in the program and the logcat error points to this.
When my phone is plugged in my cursor jumps to the left making it impossible to type or access applications that are not on the menu screen all the way to the left. It also navigates itself away from web pages and I think the constant left motion of the cursor makes the phone run slowly. I cant look at maps either.
View 2 Replies View RelatedThe structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.
View 10 Replies View RelatedI get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.
How do I merge these two informations?
I am looking after an alternative way now. As what I ideally want is:
Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure
Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList
Also this translated to TSQL it would look like
select * from contactsdata
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc
So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?

View 12 Replies View RelatedI've got a problem with my application in that the soft-keyboard is not being closed unless the user pushes the "back" button.I use several layouts which I load using the setContentView method of the application. Some layouts contain multiple EditText fields. The soft-keyboard pops up correctly when the entry boxes are being clicked, but never gets dismissed, even after I switch to a new layout using setContentView (instigated by on-screen push buttons).I found a way of apparently removing the keyboard using the "InputManager" class but how exactly does that work if I don't know which entry field opened/currently owns the keyboard?Is there a way of possibly invalidating a whole layout which would perhaps cause all resources (and hopefully the keyboard) to be cleared? As said before, I currently just use setContentView to load the next screen.

I'm writing some JUnit tests for my Android Activity.They run fine and report proper results.However, when i automate the test and start the emulator, the emulator starts with an unlock screen. This prevents the test from running correctly.How do I start an emulator without the unlock screen so that it's ready to run a test immediately? Are there commands in the emulator.exe or adb.exe that can close/ remove the unlock screen?

View 2 Replies View RelatedIf I understand it correctly, bindService() with BIND_AUTO_CREATE will start a service and will not die until all bindings are all unbinded.
But if I bindService(BIND_AUTO_CREATE) at onCreate() and hit back button to close the activity, the service calls onDestroy() and dies also.
I don't call unbind() at anytime. So is that mean when the Activity got destroyed, the binding got destroyed also and the service gets destroyed also?
What if I want the service to be always running, at the same time when the activity starts I want to bind it so that I can access the service?
If I call StartService() and then bindService() at onCreate(), it will restart the service at every launch of Activity. (Which I don't want).
So I could I start service once and then bind next time I launch the activity?
I am writing an application that listens to phone calls and perform some tasks when phone call arrives. The Application contains one activity which includes 2 buttons 'Start' and 'Stop' (where starts register the listener and stops unregister it - see code below).
The problem starts when the application is closed ( onDestroy is called ). If the user pressed on the start button and exit from the application the listener still working (which is the expected behavior) but from now it is impossible to unregister the listener since launching new instance of the application create new instance of phoneListener.
My question is:
1.Is there better way to implement my requirement?
2.Can I save the phoneListener object and reload It on application creation?

View 2 Replies View RelatedI want to create a customized ListView (or similar) which will behave like a closed (circular) one:
scrolling down - after the last item was reached the first begins (.., n-1, n, 1, 2, ..)
scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)
It sounds simple conceptually but, apparently, there is no straightforward approach to do this.
I have already received an answer (from Streets Of Boston on Android-Developers google groups), but it sounds somehow ugly :) -
I did this by creating my own list-adapter (subclassed from BaseAdapter).
I coded my own list-adapter in such a way that its getCount() method returns a HUGE number.
And if item 'x' is selected, then this item corresponds to adapter position='adapter.getCount()/2+x'
And for my adapter's method getItem(int position), i look in my array that backs up the adapter and fetch the item on index:(position-getCount()/2) % myDataItems.length
You need to do some more 'special'stuff to make it all work correctly, but you get the idea.
In principle, it is still possible to reach the end or the beginning of the list, but if you set getCount() to around a million or so, this is hard to do :-)

Where can I find information to license Google closed source apps for Android devices? These apps include

I wrote an android program that: has a main activity for UI, and it starts a service. The service timely callbacks the UI activity to update views. It works fine except: if the activity is closed (with BACK) and start again, the service will also be started again (The service plays audio file, so there are two overlapped sounds). I use bindService with BIND_AUTO_CREATE flag to start and connect to service. According to the document, it should create service only if it doesn't exist, but obviously it starts another instance when opened second time. All I want is when the activity is closed, the service goes on running, and when the activity opens again, it can reconnect to the service. Is that possible? Or I just misunderstand the usage of service?
