I am inserting around 7000 to 8000 records in my database having 4 tables each having 3 to 4 columns.Its taking me around 22 seconds to do the insertion which is i think is too long. I am using transaction while doing this without which its taking around 55 seconds.According to SQLite documentation , inserting 10000 records in a database takes time around 2 to 3 seconds.Am i missing something ,or is the behaviour correct?

I have some doubts about Android database value insertion.. How to Store Username and password in the database without using Edit text ?
View 3 Replies View RelatedI need to parse a fairly large XML file (varying between about a hundred kilobytes and several hundred kilobytes), which I'm doing using Xml#parse(String, ContentHandler). I'm currently testing this with a 152KB file.During parsing, I also insert the data in an SQLite database using calls similar to the following: getWritableDatabase().insert(TABLE_NAME, "_id", values). All of this together takes about 80 seconds for the 152KB test file (which comes down to inserting roughly 200 rows).When I comment out all insert statements (but leave in everything else, such as creating ContentValues etc.) the same file takes only 23 seconds.Is it normal for the database operations to have such a big overhead? Can I do anything about that?

View 27 Replies View RelatedI want to bulk insert about 700 records into the Android database on my next upgrade.What's the most efficient way to do this? From various posts, I know that if I use Insert statements, I should wrap them in a transaction.There's also a post about using your own database, but I need this data to go into my app's standard Android database. Note that this would only be done once per device.

View 2 Replies View RelatedI'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?

View 3 Replies View RelatedSorry if this is the wrong forum (i'm sure the thread will be moved if it is!)I am seriously considering getting the htc hero (g2 touch), but everything hinges on the availability of a mobile database app, such as Visual CE (which I currently use on my WM phone) or Handbase. Basically a customisable form-based data collection app which can be sync'ed with a desktop database. Does anyone know of such an app?PS one of the shortfalls of Android from a marketing perspective is that there is no definitive way to view all available applications - Android Market is limited when accessed via the web.
View 26 Replies View RelatedI would like to ask you smart people if anyone has seen any documentation regarding web access to a database from within an Android application. I would like to create a (FREE) application where the users can share information (rants/complains) around the globe. Each user will be able to see a little globe in his phone with locations of other users and some specific information about them.
Architecturally, I am thinking "database in my GoDaddy host, exposing a web service", and the web service accessed from the Android application. But I see no documentation about accessing web services. I can also go XML, maybe, but I am not seeing what mechanisms exist in the Android for over-the-web XML access.
I have a feeling I am mis-understanding something big in the picture. Can someone point me to docs, or knows something about this topic? (the iPhone has a Lighter app where you can see people lighting around the globe. Mine is similar, but people would not be lighting, instead they will be "complaining/ranting").
I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods:
Method 1:I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth.
Method 2:I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects.
My questions are:
Which method is faster?
Which method is easier on the phone's battery?

And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data.
