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?
I understand that to access a SQL database from Android I need to create a web service that will run on the SQL server and will process requests from the Android application, what I need to know is how to create this web service and how to access it from Android.

View 1 Replies View RelatedI'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things.

View 3 Replies View RelatedI put my database field in "assets" folder. 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. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?
