Android :: Include Information To Droid Application Post Compilation?

May 20, 2010

Currently I supply a user with a URL to click on to download my j2me application. This URL includes their user id as a parameter, a servlet takes this information and dynamically creates a jad file that includes this user id , thus making the user id available to the j2me app.

However, I am now using j2me polish to compile my program and thus have the compiled .apk for this same program. However, I cannot work out how to make this information accessible to the the compiled program as there is no jad / jar mechanism. The information is only available at the time of download.

Any suggestions gratefully received! (is this even possible in an android application?)

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

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 :: 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 :: Data Not Inserting In Sqlite Database

Aug 14, 2010

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.

this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

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?

Android : How To Update A Database Used As A Source Of Data By App

Aug 4, 2010

I have an app which uses a large amount of data which has been compiled outside the app (on my main PC). The app is for my personal use so there are no complications with having to distribute data updates to other users. However, I am currently following a very convoluted and time-consuming procedure each time I want to update the data, and I wonder if anyone can suggest any ways to streamline it.

The procedure I follow whenever I want to add new data is as follows:

I enter the new data into a csv file which I maintain as the source of the relevant table in the database. I use SQLite Database Browser to import the data into an existing SQLite database. (This program does not seem to have the ability to append imported data into an existing table, so whenever a table needs updating I have to delete the existing table, then import data from the csv file into a new table, then manually edit the data types for all the fields in the table.)

I drag the icon for the database file onto the 'assets' folder of my project in Eclipse. I export the project from Eclipse as an apk file. I copy the apk file to my phone (using Astro File Manager) I uninstall the old version of the app and install the new apk.
when the app is run, code based on the example set out here copies the data from the 'assets' folder into the app's data folder; this means that each byte of data takes up two bytes in the phone's internal memory; at present this is not a problem, but could be as the volume of data grows; I wonder if there is a more memory-efficient method?

Android :: Insert Data Into A Remote Mysql Database

Nov 24, 2010

We have an android app that currently sends data to a php script which writes to a mysql DB on the same server. We are thinking of using a scalable remote DB e.g. amazon RDS.The question is how does our android app write to these remote DBs? Do they have some kind of rest API, or do we have to send the data to the same php script on our server but use that to post to the remote mysql DB?
