My 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.
I have a cursor adapter and the logcat is filled with above errors, as soon as I click on a view. I am already releasing the CursorAdapter's cursor in onDestroy().Is there any way to get information about when the cursor was opened?
View 3 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 contains 2 activities A and B. B is opened with startActivity(intent) in A, when B is closed with finish(), I found the method finalize() of B is not called.
My question is: How to force Activity to call finalize() when it is closed with finish()?
When I run my app in debug mode I constantly get the debugger breaking out due to a IllegalStateException:
CODE:...........
I have checked on this group and realise it must be because I have not closed a cursor somewhere but I have checked a million times and I am absolutely sure I always either call startManagingCursor() or close all my cursors explicitly.
Yet I still get these exceptions and it's not just the odd one - sometimes I get 5 in a row! The only thing I can think of it that I have mis-understood somewhere along the line and I am misusing cursors somehow!
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?
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?

Does anyone know of an app that can track one's sleep and mood and overall energy level day to day? I'm looking for something that'll let me rate my fatigue level from 1-10, my overall (i.e. "How do you feel today") from 1-10, the hours of sleep I got, the minutes of exercise, that sort of thing, and then export to CSV so I can keep a record.
I'm looking for an expense-tracking app-specifically one that has catagories, a budget and deducts from those catagories when you input expenses. Can anyone recommend something like this? I downloaded iSpend but it wasn't sufficient for what I was looking for. It wouldn't let me deduct from certain catagories and track spending.
View 3 Replies View Relatedlet's say i want to build a smartphone app that tells a user when/where to get off a subway station. i can think of two ways of doing this:
1) using GPS and map of the subway routes, track the location of the user and notifies him when the destination is reached
2) have him press start when he gets on a train as the train starts (which may not be realistic because the user could simply forget to do this), use the known travel time from starting station to end station, and simply notifies him when the time is up.
I've been using an app called Driver Log to track my mileage I drive for work. The app is simple, but it works. It has a start button and and end button. You press start and gets your current location. You press End when you get where you're going and it gets your end destination. Then it calculates the distance and uploads it to a Google docs spreadsheet. Again, it's simple, but it works.
The problem is that under 2.2 it doesn't work well. I gets your starting destination, but if the phone sleeps before you get to your destination, this is lost so your whole trip is a bust. The app is no longer in the market so I can assume the developer has no plans on fixing this. Can anyone suggest a similar app?

View 9 Replies View RelatedI wanted to introduce to you the expense tracking app, ProOnGo Expense. It simplifies the entire expense recording process by letting users create their expense reports just by taking pictures of their receipts. Users can then export their expense reports as an Excel spreadsheet or they can sync ProOnGo Expense with an accounting system like QuickBooks Pro. We also offer the ability for employees to export their expenses in their company's expense report template.Users can also use our Web Portal to access their previous expenses, make changes or delete them, or if their business is signed up with ProOnGo, they can submit, approve or deny the expense.The web portal also let's users customize the expense categories in the app. If there are unique expense categories, such as Horse Feed, users can make the changes via the Web Portal and the app will be updated.And just recently, we've added a new feature that allows users to submit their receipts to the Receipt Reader from their email. So a user just has to attach the receipt images to an email and send it to ProOnGo, and the merchant name, date and total amount will be extracted from each receipt and generated as an expense.

Usually they ate pretty accurate, but on a longer run, the discrepencies are more pronounced. For instance, I went for a 14 mile run today and Sporty pal told me that I went 14 miles while cardio trainer said I went 15... That's a big difference.
My app is running into the following crash and I'm having a hard time diagnosing it. We have multiple background threads (including a couple pthreads started via JNI that are making calls back up to Java occasionally), but none of them are reporting errors . Any suggestions on how to go about isolating this? There are no symbols in libdvm, so I've been unable to figure out where the stack trace points. This has happened 3 times so far, with the same stack trace each time.

Has anyone used this app or anything similar?
My friend's daughter is sneaking out of the house and night and she needs to catch her I reccomended getting her an android phone and loading something like this on it.
Just wondering if it is as good as it claims to be, all the sites I have found about it seem to be nothing more than canned marketing material, that concerns me a bit.
Any other suggestions? Needs to be fairly stealthy this is a teenager we are dealing with afterall will probably be pretty familiar with the phone fast.
Other though was just to install WaveSecure not give her the pin number for it and tell her it's in case the phone gets stolen.
All new to this forum and just got my first android phone over the weekend which I'm really excited about and so far love every minute of it. The reason for this posting is because I'm looking for a certain application. I know there are many flight tracker apps out there but I seem to remember hearing about on app which you could just point your phone at a specific airplane it would give you information about where it originated and where it was headed, it was great because you didn't have to enter any information and you could track random flights that you saw going overhead.

There are various applications available but i can't get any start.
i found a Google open source application but still it don't have online data checking feature.
I find that the tracking on wave secure isn't really that efficient especially since it's now an app with a monthly subscription. The main reason is that the gps tracking on it is really pretty poor in accuracy and this is the main thing I use it for. So are there any alternatives with more accurate tracking on it? ( I mean google maps gives it more accurate than WS)
View 4 Replies View RelatedThis shouldn't be that hard to make.( I don't think ) But how about an app sort of like a stolen phone tracking system? It would be hidden inside the phone so you couldn't see it but if anyone ever steals your phone, you can call the phone tracking systems company and find out where it is/who stole it? I think this would be useful because everyone wants this phone and after 90 days of this phone, you can unlock it so I'm pretty sure everyone wants to keep their phone safe.

I'm looking for a Mileage Tracker App, if anyone knows of one. I plan on driving from location to location frequently throughout my work day, and I'd like to be able to save time on keeping track of my mileage by having an app that does it for me. What I'm looking for is to be able to get in my car, have the GPS on, open the app and press start. From there, I want the GPS to track my location, just like it would do for navigation. When I get to my destination, I want to be able press stop and have it tell me (and log on a daily, weekly, or monthly page) the mileage for each trip.
i.e.
11/20/10 3:35pm - 3:50pm 10.3 mi [View Map]
11/20/10 5:22pm - 5:45pm 24.6 mi [View Map] <--- Button to press to view map
I'd also like for it to record the path I took on a map (as seen above), so that I can easily identify where I am driving to and from, when trying to fill out a mileage sheet.
