Android :: To Mock Sqlite3 Cursor When No Db / Table Exists?

Sep 16, 2010

I am using a ContentProvider for caching results from a web-service query. It is an HTTP request and the response content is XML. Most of the data is cached, so I simply query the DB, if not found, request from webservice, insert in DB and requery the DB. Thus the response is always a Cursor from SQLiteDatabaseHelper.
I have one result set that is not stored in the DB and since it is 100% transient, but I would like to provide the appearance of it coming from the DB's Cursor. Is there an easy way to do this? For example, if I could project it onto the cursor with a cursor.setValue("string", objectValue) or some other existing implementation.
If not, I will either bypass the DB for this content result, or stuff it into a trivial table that is constantly reused.

Android :: Querying SQLite DB In Android Activity - Saying No Column Found - Although It Exists

Aug 10, 2010

See title for explanation.

Here is the method I'm using:

CODE:.........

And here is the call to the method:

CODE:...........

Why it would be throwing the "No Column Found with name=Test", although my DB explorer shows there is indeed a column named name and a value in a row named Test?

Android :: Sqlite Exception No Such Table?

Nov 13, 2010

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?

Android :: Game - Duplicating Entire Table (SQLite)

Apr 6, 2010

In my game I am handling the loss of a character (represented programmatically with their own table) - however there are 4 such tables. I would like to know if there is a simple way to simply tell SQLite to make character 2's entire table equal character 3's? Just trying to not leave a gap in the lineup.

I was considering pulling all the data, sorting it out, putting it into the table and then deleting - I just wanted to know if there was a nifty shortcut to tell SQLite that I wanted to duplicate an entire table at another preexisting table?

Android :: Detect If A Table Contains A Column In Droid / Sqlite

Apr 20, 2010

So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.

Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.

Android :: Copy Row Data From One Table To Another In SQLite Droid?

Oct 11, 2010

How do i efficiently copy a row data from one table to another table, where both of them are the same structure. i could go the much harder way of retrieving initial values from the row in the first table and then inserting to the second table. But i feel there is a more efficient way this can be done.

Android : SQLite Cursor Out Of Bounds Exception On SELECT Count FROM Table

Jun 22, 2010

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?

Android :: Insert Data On Sqlite Database Table From Word Or Excel Document?

May 22, 2010

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Sqlite Query - Record Is Being Returned If Table Is Empty?

Mar 21, 2012

I've a problem with a query in sqlite3.

The query is very simple:

SELECT MAX (INIT_DATE) INIT_DATE FROM TABLE;

When my application execute this query, and the table is empty, a record is returned. I can't understand why a record is being returned if the table is empty. It should return cero results.

I've tried to execute the query in two different ways:

cursor = db.query(true, "TABLE", new String[] {"MAX(INIT_DATE) AS INIT_DATE"}, null, null, null, null, null, null);

cursor = db.rawQuery("SELECT MAX(INIT_DATE) AS INIT_DATE FROM TABLE", null);

Android :: Child Views Of Particular Table Row In Table Layout?

Jul 15, 2009

Here is my screen description: It is a TableLayout and it contains multiple Rows. I have set TableRow as clickable, as I want to go to next screen on click of a tableRow. Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.

Android :: Adding Table Row By Inflating Does Not Take Table's Settings

Nov 4, 2010

I have a table layout with a few predefined rows in it. Each row has only two columns.

Now I need to dynamically add additional rows in it.

I have two problems:

1) When programmatically inflating, I cannot set the index of the newly created row (I want it in place 'n') 2) After inflation, the inserted (actually appended) row doesn't listen to parent table's stretch column property.

So here are my questions:

q1) Can I set the place where to insert the inflated row programatically ?

q2) Why doesn't the new row inflate properly (the second column is not shown because the first column doesn't contains a TextView with fill_parent.

In the end I need the first column to occupy 80% of the screen width, and the second column remaining 20%.

q3) is that doable with programmatic row insertions ?

Android :: Dynamically Add Table Row To Table Layout

Jul 8, 2010

When a button is clicked, the following method is run:

public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);......................

R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?

Android :: Checking Whether DB Exists

Aug 25, 2009

I would like to check whether there is any direct API available to check whether a particular Database exists or not ?

Currently, to initialize data for the first time (not repeatedly), we try of open the db and if it fails we know the database does not exists otherwise it is already created and initialized.

Is there any simple API available to check whether DB exists or not ?

Android :: Valid Network Exists

Dec 23, 2009

I am struggling to find a way to determine if a valid network is available to an app. specifically, if there's a problem making a network connection, i would like to be determine if it's on the client (app) side, or a problem with the remote server. i happen to be attempting a URL connection (using http client) and the wide and varied possible exceptions don't seem like a reliable method. for example, when the network is down on the phone, i received "unknown host exception", which doesn't really indicate the root cause ... it's possible to get that exception with a valid network connection also. at other times i get other exceptions, such as socket exception. is there a way to ask the phone if it's network ready? the other option i thought was to ping a known good server to see if it responds ... with an IP address. kind of a heavy weight option and not foolproof.
