I have a query that selects rows in a ListView without having a limit. But now that i have implemented a SharedPreferences that the user can select how much rows will be displayed in the ListView, my SQLite query doesnt work. Im passing the argument this way:
I'm using the SQLite3 database system in the Android library. I need to execute a query during a transaction to see if there is a similar entry already there. If there is, I have to perform some other logic and adjustments before I add a new row. Can I execute a query within a transaction and get the result back immediately?
Is there any way out to achieve "SELECT * FROM tblname WHERE name LIKE '%[0-9]%' ". i know we can't do this with sqlite~ but how to deal with such query task with sqlite? i tried to use REGEXP ~but unluckily it is not pre-defined~ so i tried to define it by myself...but even i couldn't find a way in android to create a UserDefinedFunction...
Im trying to get an object form my SQLite database in my Android application. I know that the contact is in the database because when I add it and try finding by ID, it returns the object. When I try finding by first and last name, though, it throws an exception and Im left with a null reference.
Here is the query:
Ive also tried to find just by first name and just by last name. Same result as above.
The exception is an SQLite exception
no such column: aurelius: , while compiling: SELECT _id, last_name, first_name, email_address, organization_name, label, label_position FROM contacts WHERE first_name=marcus AND last_name=aurelius
And also happens when trying to select just first or last name
no such column: marcus: , while compiling: SELECT _id, last_name, first_name, email_address, organization_name, label, label_position FROM contacts WHERE first_name=marcus
Have been using a SQLite database, Theres a situation where i have a list which displays all the "name" field data of a table "table1". Now i have a button to insert data in "table1". The list is populated using a simple cursor adapter which is passed a cursor "cursor1" populated with the data. "cursor1" is prepared using the SQLite query - "SELECT * FROM table1". Now the moment i insert data, i need to update the list too.
My question is- will the Adapter sense the database change automatically (i guess not)? using cursor1.requery() is correct or should i use cursor1 = db.query("table1", null, null, null, null, null, null);
I have a problem programming with android SDK 1.6. I'm doing the same things of the "notepad exaple" but the programm crash when i try some query. If i try to do a query directly in to the DatabaseHelper create() metod it goes, but out of this function it doesn't.
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?
In my Android application user can fill database with imported data, then perform predefined, complex SQL query. With some data pattern, query will take very long (minutes and more on HTC Hero), while common usage will not exceed 10-15 seconds.
Is there any way to cancel pending SQLite query on Android? Timeout would be as good as well, partial results are not required. I'm performing query within AsyncTask.doInBackground()
I know best way is optimize query or change app logic, but in this case results depends on user knowledge anyway, so I'd like to help those who enter troublesome pattern.
I dont what to give any background to activity when i leave this propery blank it gives me error, and i have tried using @null as a value but it shows black background.can any one guide how to make it transparent?
I am creating a few layouts with the root element being merge. inside the merge element i have a ScrollView containing a TextView. I am getting 2 errors: there is no resource to match the layout_below and layout above names i have put in.I have another layout xml file including very similar components, some of which also reference @id/headingLayout and @id/tabsLayout. Both of these XML layout files do not contain the component with name headingLayout or tabsLayout.Why is it that one layout file has no errors about these references and the other layout file does? What the crap am i doing wrong, the app will build and run like i expect, until i add this merge to another layout?I have even tried copying the xml from the working layout file, to find that it gives the same errors, something must be wrong with my new layout file. I have tried cleaning, rebuilding, opening/closing eclipse..
I have recently gotten back into developing Android applications. However, every time I try to run an application on my phone now, I get the error message - "Parse Error - There is a problem parsing the package."
Two years ago, I used Eclipse to develop projects, which is what I'm using now. Though, I had to reinstall eclipse and everything else. So it's a new setup but I believe it's the same general setup.
I can put my old .apk files on my phone, and they work fine. If I put any newly created .apk files on my phone, I get the parse error.
I also found that if I compile any OLD projects and then copy those onto my phone, that I get the parse error.
This leads me to believe I've got something set up wrong in Eclipse that my phone isn't liking.
I thought maybe it was the virtual device manager, so I've tried several combinations of virtual devices - 1.5, 2.1, 2.2, 2.3.3 - using any of them still gives the parse error when trying to run the applications on my phone.
By the way, all of these projects work in the emulator running through Eclipse, so I know they work.
Lately I have been trying to install a ROM on to my phone, but I cant get the files onto my SD card. Keeps saying, "Cannot copy item. The device has either stopped responding or has been disconnected.". I just rooted the phone about a week ago and figured I would change the ROM. Also tried unblocking the files but got nowhere. Also tried other ROMs, nothing is working. But I can transfer files to and from my SD card with no error.
I am currently developing android XMPP client to communicate with the Tigase server setup locally.Before starting development on Android I am writing a simple java code on PC to test connectivity with XMPP server.My XMPP domain is my pc name "mwbn43-1" and administrator username and passwords are admin and tigase respectively.Could anyone please tell me the solution for this problem.I checked the XMPPConnection.java file in the Smack API and it looks the same as given in the link solution.
