In my activity, I have an AutoCompleteTextView that gets its contents from my custom adapter. I created my adapter by following this example.The adapter works so far, but I am getting so many errors on leaks and cursors that are not finalized.My question is: how do I close the db in runQueryOnBackgroundThread?

I am seeing the exception in 'adb logcat'.But I don't know if it is caused by my application or android platform.Can you please give me any idea how to troubleshoot this exception?
View 3 Replies View RelatedCan someone point me to right direction, how to create an adapter for AutoCompleteTextView, which would be getting data from SQLite DB, using data, which user entered into the text field? I want to use the user-entered data to filter suggestions for autocompletion.I imagine that adapter should always take user-entered data as soon as changes appears and use it for fetching suggestions on-the-fly. Is that possible? So far I've seen many tutorials for autocompletion where static String arrays were used, but never seen them build dynamically.Is it possible to do it automatically or I need always fetch String array myself and pass as ArrayList to adapter on every AutoCompleteTextView change?
View 1 Replies View RelatedI've got a query, (I'm using rawQuery())
SELECT * FROM <table>
I'm then storing what it returns using a cursor. From their what I want to do is, start at the first row so.. cursor.moveToFirst() then take each column , column by column and store its particular value in a variable. I then want to move onto the next row and do the same. So I guess my question is How would I get cursor to deal with multiple columns?

View 2 Replies View RelatedI am having some trouble working with the SQLite database. I am able to create the database, add to it, and delete from it with no problem by following the Notepad examples, but I am trying to avoid duplicates and therefore want to check to see if an entry exists already.
Below is the code I have for testing to see if a game exists. I get the correct Log message of "No Games" when there are no games, as well as the correct value for column from getColumnIndex which is proven to me by the log printout telling me that column = 1.
The error message that I receive if I don't catch the exception says "Caused by android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1
Where is Index -1 being requested if my call to getColumnIndex is returning 1? Code...
The following function is giving me an out of bounds exception...
public void count(){
SQLiteDatabase db = table.getWritableDatabase();
String count = "SELECT count(*) FROM table";
Cursor mcursor = db.rawQuery(count, null);
int icount = mcursor.getInt(0);
System.out.println("NUMBER IN DB: " + icount);}
It's meant to return the number of rows in the database. Anybody know whats wrong? am I perhaps doing this task the wrong way?
I have an minor issue when taking a photo. I have a button that invokes the camera, successfully takes a photo, and returns to my entry form. My only problem is the database leak that occurs when pressing the button to call the camera.
My code looks a little something like this.
code:..........
I run :

In the onCreate of the Activity or Class that I am calling the camera in. I have not coded in mDbHelper.close(); anywhere not sure if i should when or where. I think i would rather just leave it open while capturing one image.

Everything seems to be working fine, but i would defiantly like to avoid any issues amongst the many android devices out there.
The 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.

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?
Okay so a month or so ago I rooted with Unrevoked and put on the 2.2 leak that was available at the time. I doubt I'll get an OTA for the official 2.2 but I saw the update.zip was made available. Is there anyway to put this on my phone? I'm assuming I'll have to downgrade to stock RUU first and then I'll lose root and lose all my backup info. Basically I want the new 2.2 but I don't want to lose my data. Is this possible yet and if so how do you do it? There are a gazillion threads about similar issues but I haven't seen one that specifically talks about this yet, although it's probably in here somewhere.

View 1 Replies View RelatedSo this is a response to another thread, that I never got a reaction on. Hopefully someone can give a hand. I have a AutoCompleteTextView with a CursorAdapter with data. I need to be able to set a text in the AutoCompleteTextView programmatically without the autocomplete mechanism kicking in. If I use *setText *on the AutoCompleteTextView it will start the autocomplete. I tried calling *dismissDropDown() after setText, but this dosnt work because the drop down is not shown yet.

View 2 Replies View RelatedI'm using an autocomplete box, with suggestions provided by a SimpleQueryAdapter.Not sure if relevant, but only difference I see is that, both in the adapter constructor, as well as in runQuery(), I use a cursor returned by SQLiteDatabase#query obtained via an SQLiteOpenHelper instance.Should I be using on these cursors or not?If I don't use managed cursors, then I get "leak found" warnings ("database was created [sic] but never closed").

View 3 Replies View RelatedI just got my first Android phone (N1), and like it so far.There are a few things that drive me up the wall, though.One of them is the 'autocomplete' (not sure what it's called): where Android suggests words as you type a text message. Great when I'm typing English, not so great when using other languages.Can this be turned off?
View 4 Replies View RelatedI cannot seem to dictate the behavior of the onClick function.When a suggestion is clicked, it fires off the intent immediately. Is there a way for it to instead of firing off the intent immediately,simply copy and paste the suggestion as part of the search string?Eg. when typing in J,o,h the suggestion "John" comes up. When I click "John" can it copy that text into the search bar instead of immediately processing the search with John?I'm assuming theres a simple configuration which I cant seem to find.I dont want to go extensively into catching the fired of intent and re-processing etc

View 3 Replies View RelatedI've run into an issue with an autocomplete field I'm working on.The field I'm working with is composed of the form "<NAME> (<CODE>)".When a user starts typing in text, I want to display any results that match either NAME or CODE.For example, if this list contains items and their codes, like "Personal Computer (PC)", then I'd want the list to pop up that row if the user types "P", "PC", "Per", etc.However, the problem I'm running into now is how to best sort the results that come back from this.For example, If someone enters "PC", I want "Personal Computer (PC)" to be the first result. However, if there's another row (you'll have to bear with me as this is contrived) "PC Case (301)", then there's no simple ordering I can do on the results to ensure that the best match appears first. Ordering by name and code both returns PC Case first.I want a query where it returns the best match first, rather than items in alphabetical order.Is there such a function I can use in SQLite to get this, or should I return the results and then mess with the order in the code?

View 25 Replies View RelatedIn my Android app I want to have an input field with autocomplete. The number of items will be about 300000. The best solution seems to be to put the items into a file (on sdcard), one item per line, each line would have the same number of characters so that I can seek to specific line number. If the user enters something in the text field, I would binary search (via RandomAccessFile) the file and show suggestions.I want the autocomplete to be super fast (ideally under 100ms but I guess it's impossible), what optimizations I can do?
Update 1:
I will convert the users input to lowercase english characters (a-z) with spaces. So 'A/b' would be converted to 'a b' and then searched.

I now realized I need additional thing - to search for word-starting substrings.
