Android :: Retrieving Data From The Database

Jul 10, 2009

I created the following method for retrieving stored settings from the database:

public String getEntry(long rowIndex){
String value = "";

Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}

return value;
}

On debugging I can see cursor c contains two columns and one row but when it comes to line

String value = c.getString(columnIndex);

it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

Android :: Retrieving Data From USSD Command

May 17, 2009

I want to call a USSD (http://en.wikipedia.org/wiki/USSD) command and have the reply returned as a String. I can make the device automatically dial the USSD - like so

// String encodedHash = Uri.encode("#"); String ussd = "*" + encodedHash + "105" + encodedHash; startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)), 1); //

This calls the USSD and the result is displayed in an alert menu generated by the OS dialer. There's no way that I can see to intercept the USSD reply, prevent the dialer displaying it, and then use the result as a String. Essentially, all I really want to do is (pseudo code) // String ussdReply = call("*#105#"); // I've tried creating an "onActivityResult" but it never receives anything from the startActivityForResult. So, does anyone know how I can use the reply within an application?

Android :: AppWidget Retrieving Data From Another Application

Apr 30, 2010

I have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.

Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:

1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?

Android :: Error When Retrieving OData Data While Using OData4J

Nov 2, 2010

I am trying to use OData4J to retrieve a list of Users from the StackOverflow OData service (onto an Android 2.1 device), but it isn't working.

public static Enumerable<OEntity> getUserInfo() {
ODataConsumer c = ODataConsumer.create("https://odata.sqlazurelabs.com/OData.svc/v0.1/rp1uiewita/StackOverflow/");
return c.getEntities("Users").execute();

I think it is unable to retrieve data from the URL. Any ideas why this would be? Is there anything wrong with my code?

Android :: Retrieving And Parsing ICal Data Over HTTP

Jan 23, 2010

I am making an application that asks the user for userid, appends the userid to a static HTTP link to retrieve the user's daily schedule info file that has a .ical (calendar) extension. I need to read the data from file, format in new UI and representing some useful data on an Android device. My query is can I access a static HTTP link behind the scenes? And when I use the same link on desktop browser, it asks user to save the file — how can I do this on a mobile? Do I need to read the data and save it somewhere or I can save the .ical file and read from it?

General :: Retrieving Google Keep Data

Aug 20, 2013

I have the following issue; a couple of months ago i had a Desire z (happy HTC One owner now) but it fell and it broke. Or atleast the phone itself/ screen does nothing. However i can hook the phone up to my pc and its get recognized and i can browse the phone with the command prompt.

My phone broke while i was on a trip in Thailand and unfortunately the info (email adresses from new friends) that i typed into google keep that night had not been synced yet...

I would very much like to get this info off of my phone and read it or transfer it to my new phone or something (reading it on the pc has my preference as my HTC One is not rooted).

Android :: Data Passing And Database Access

Sep 23, 2009

I am experiencing a problem where when the android device wake up from sleep, the Activity would take forever to get redrawn(and have to terminate it most of the time). I am not sure why, but when I comment out the code below where it retrieves an object from the database based on id stored in the bundle, the problem goes away.

Not sure why the db transaction is causing an issue.

secondly, is it better to store the object in bundle instead of storing its id and retrieving it from db in onCreate?

Android :: Put Static Data Into SQLite Database?

Jun 8, 2010

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

Android : Regarding Storing Of Data From User In Database

Aug 19, 2010

I am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.

1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.

Android : How To Add User Customized Data To Database?

May 9, 2010

I am trying to design a sqlite database that will store notes. Each of these notes will have common fields like title, due date, details, priority, and completed.

In addition though, I would like to add data for more specialized notes like price for shopping list items and author/publisher data for books.

I also want to have a few general purpose fields that users can fill with whatever text data they want. How can I design my database table in this case?

I could just have a field for each piece of data for every note, but that would waste a lot of fields and I'd like to have other options and suggestions.

Android : How Can I View Data From Database Using Textview?

Aug 12, 2010

I'm doing an admin page that can view the users that exist in the system. My idea is to show a list of the users and the details in one page. I heard that using listview is very tedious. Is there any other way that is easy?

Maybe view in textview but I dont know how it works. I must put in a lot of textview on my xml? A simple task that I need to know how to do. I just need to know how to view data's in a page, using any method. Code...

As you can see I tried to put data from my database straight into the array but it can't work; final String[] TEST = c.getString(1);. The error message Type mismatch: cannot convert from String to String[] appeared.

Android : Creating App Database With Big Amount Of Data

Dec 23, 2009

The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which
is loaded with Resources.openRawResource(id).

It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This
my code to do this : Code...

The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentuated characters appears well.

But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions?
