Android :: Storing Object Into SQLlite Database

Nov 16, 2010

I would like to store an object into a SQLlite database. I am looking for how to best do it in order to ensure that if I need to updata/change this object in the future that users of the new and old object layout will be minimally impacted. In other words I want to ensure that making changes to the object will have minimum affect on clients that do not update their software on the old database format.

I want to also ensure an easy update from the old record style to the new format. I was thinking that I could add an element in the SQL row to identify the object type with a unique name, and to identify the object version number. That way I could read the row and use the object number to control the deserializer to use the correct version of the class.

Android :: Android - Accessing Single Database From Multiple Activities In Application

Dec 15, 2009

I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different parts of the data in real time.

Currently, I have each activity open its own DBManager object (the helper class I created to manage the database). This is causing problems though and I would like a slightly more global access solution so I don't have to keep opening/closing/creating a database.

I'm considering several options, and would like to hear pros and cons of each as well as other suggestions.

Singleton style. Have a wrapper class that returns a reference to the only database manager so any activity that needs it can use it.

Static Manager. Have the manager class be entirely static members and have it open the database on load. Easily accessible by anyone that needs it (which is everyone).

Merger between 1 and 2. I could make a database manager class that initializes the member singleton instance of the database and all of the data manipulation methods were static. Then I wouldn't even need a reference to the singleton to access the database.

Android :: Load Data From A URL To SQLLite?

Oct 30, 2010

What's the easiest way to populate a SQLLite table with data off a URL?

I'm writing a Delphi web app that will generate a file on a server for my Android app to download.

In Delphi, I'll probably save it as a .csv file and use bulk import to import into MS SQL Server.

What's the easiest / best practice way to do this in Android? How would I download the file from the URL and then load it into SQLLite?

Android :: SQLlite Crashes After Try To Retrieving Data

Jun 6, 2010

I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like:

public class DBAdapter
{
public static final String KEY_ROWID = "_id";
public static final String KEY_LATITUDE = "latitude";
public static final String KEY_LONGITUDE = "longitude";
private static final String TAG = "DBAdapter";....................

Android :: Write Content Provider Not Backed By SQLLite?

Mar 16, 2009

Has anyone got an example of how to write a ContentProvider that gets its data from somewhere other than a SQLLite database? Mine is half working, in so much as I can retrieve the requested data and apparently populate a MatrixCursor, but I can't figure out what I'm supposed to do with the 'projections' parameter supplied to the 'query()' method.

Android :: ListActivity - Alter Data From SQLLite Before Putting Into Row

Dec 11, 2009

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_list);

mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
fillData();

registerForContextMenu(getListView());....................

The date is actually stored as an int in the SQLLite database, and thus it displays as an integer. Does anyone know a way to create a date from the int so it doesn't display as 1216544611 (or whatever) but as "12/11/2009 11:32"?

Android :: Tips - Tools For Working With SqlLite In Phone?

Nov 14, 2010

I'm a .NET developer starting to dig into an android application. One thing that seems a little abstract is working with SqlLite. In a .NET application, I can do my Database setup, query testing and profiling, and enter in some test records through Management Studio for MSSQL. In fact, I'm constantly in Management Studio checking something - so I'm finding it difficult to work without a similar tool.

What are some good tools/tricks to use when developing SQLLite on Android? The tool doesn't have to have a GUI, but would be nice if I could run it as a desktop app and have it look at the same DB as my emulator.

For instance, something that will allow me to run a simple SELECT statement against a table to view records without having to do it through android?

Android :: Droid Sqllite Taking Long Time To Complete / Options For Moving To Start Of Result Set?

Nov 2, 2010

I am working on building an android app but I'm nothing that my SQL operations are taking forever to complete

I have profiled the app to narrow it down to the act of moving the Cursor to the first row of the result set for a simple select query (only returning 1 row where I'm testing it to eliminate the size of the result set as a problem.

Are there any better options for moving to the start of the result set?

edit:

some code...

this runs 3 times and i have time it to approximately 2 secs for all the rest of the code or over a minute with this in.

i have also run just the rawQuery statement with out the move to first and its takes bout 18 secs so im looking at the worst part of the code first.

Android :: Android SqlLite ContextWrapper.openOrCreateDatabase() Nullpointer?

Nov 18, 2010

I have created a program, with a service - the service is "START_STICKY". So when i close the program (i am using Advanced Task Killer, to kill programs) the service is restarted automatically, but this presents a problem cause i get an error when trying to call ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203) (see stacktrace below).

I have created a class to handle context, which will return my Activity's context if it is not null, or a fake one i created if the activity's context is null - and the activity's context is null so the fake one is used, i suspect this may be the problem, but have no idea.

In my activity i have a constructor which gives a reference of it self to the contexthandling class, but it seems the activity is not instantiated (not before the service is started at least) when the system is restarting my service.

There is of cause no problem when the program is just started normally, the service starts fine then... which is why i am suspecting the fake context, i created it as follows (and it is referenced in the manifest application tag with android:name=FakeContext):

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

Stacktrace:
