I created a sql lite database with the following columns:
static final String dbName="demoDB";
static final String tableName="Employees";
static final String colID="EmployeeID";
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("CREATE TABLE "+tableName+" ("+colID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+
colName+" TEXT, "+colAge+" Integer);");
I want to select all the records in the database like this and display them in a gridview:SQLiteDatabase db=this.getWritableDatabase();Cursor cur= db.rawQuery("Select "+colName+", "+colAge+" from "+tableName, new String [] {});String [] from=new String []{DatabaseHelper.colName,DatabaseHelper.colAge};
int [] to=new int [] {R.id.colName,R.id.colAge};
SimpleCursorAdapter sca=new SimpleCursorAdapter(this,R.layout.gridrow,c,from,to);
GridView grid=(GridView)findViewById(R.id.grid);
grid.setAdapter(sca);but i receive the following exception:java.lang.IllegalArgumentException: column '_id' does not exist.the db table does not have a column with name '_id'so what is wrong with this code
I have decided that I hate SQL and for that purpose I am trying to make a helper class that I can reuse over and over and never have to mess with it again but it isnt working!
Here is what i have right now:
CODE:.........
I have included several System.out.println() statements to help me debug the code and find problems so please ignore them. PrintDB is another test that I wrote that I am using to make sure everything is working. Now this is what I have written to make sure everything is working....
CODE:.....................
Running this code everything goes great and all the System.out.println() statements have the right information in them until it gets to the databaseView.setText(db.printTable(tableName));
part and it throws an exception
CODE:................
This has me so confused because that same line of code is used in the getColNames() method that was called several times before this and ran with no problem. Also if the table didn't exist wouldn't it have thrown an exception when I called insertRow()? I called that method 5 times in a row with not a single exception thrown! What is happening here?
Implement onCreate() in your DBOpenHelper. Put there content of the createTable() method.
Why would it be necessary to create the table in the onCreate() method? If I were to do this would I be able to use my existing method to do so and just call it from this method?
And the second why you don't use content providers and uri >concept which is already SQLless?
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:
CODE:..........
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
I 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 am developing an Android application where I get the exception while writing to the database: An exception occurred: android.database.sqlite.SQLiteException
But it doest say anything else. In general I find it very difficult to debug the exceptions.
I am using Eclipse to develop the application. Please help me in solving this issue..
Started coding up a simple android app. Part of it pulls the users last 20 tweets and saves them to a database. When I run this, statuses = twitter.getUserTimeline(); throws an exception its handled and prints out: failed to get timeline-permission denied. When I run the same code non-android, it works fine. I'm a little bit baffled. Could android be limiting the network connection?
Im using some database helper classes, haven't included the code because the exception is thrown before any of these are even involved :

In Android is it possible to insert a sqlite timestamp into a database using ContentValues?
When I try to add it using something like
ContentValues args = new ContentValues();
args.put(MY_DATE,my_date);
I get an error telling me that my_date needs to be a string
This error is driving me partially insane, it only surfaces on motorola droid / milestone devices, it works flawlessly on the hero and g1. Not got a droid to test it on so have to go on the crash reports in the android market. If you can shed any light onto this matter, I have gone through every db open and made sure it was closed.

View 3 Replies View RelatedUsing appbrain on my PC seems to work fine when I'm not logged in. When I do log in and try to click on an app I get this error message:
"Error: Server Error The server encountered an error and could not complete your request. If the problem persists, please report your problem and mention this error message and the query that caused it."
Anyone else have this issue when using Appbrain on their pc?
Well, It looks like I solved the problem. I just deleted my account and created it again and it's fixed (for now).
The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check).
My environment is:
Fedora Eclipse Platform
Version: 3.4.2
Based on build id: 20090211-1700
My target is Android API level 5.
The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error.

I have a problem with a strange out of memory exception that only occurs on some devices (mostly HTC Desire). It happens there every time a user starts a certain activity (no matter how - there are two paths to that activity) and i'm really puzzled as to why (i checked for leaks and couldn't find any)...
The error is either thrown when calling setContentView or shortly after.
This is the code block that throws the error:
CODE:.........
As i said - the error is usually thrown when calling setContentView or when calling getMonthTimeStamps()
getMonthTimeStamps is a helper function which creates a list of dates available in the internal database. It creates a couple of (small objects) and returns an ArrayList.
Here is the function:

I'm not claiming that my code is flawless or perfect, but i really don't understand why this error is thrown. The XML-layout doesn't contain any references to images and not very complicated (textview, spinner, tablelayout).
Here is the error log i received from one user:
CODE:.....................
I think the error is from this manifest file? when i want to start this activity "SearchResultForm" i have the exception?

I read somewhere not to exception handle when developing in Android, is that true?
If one does need to exception handle are there any logging tools for 2.1 and above?
If shouldn't exception handle, why is it not recommended to at least use the below?
