Android :: Database Disappeared After Application Downloads?
Aug 13, 2010
One of my applications downloads a database from a server. When I install the application onto my phone, it downloads the file correctly and loads the information, no exceptions thrown or anything. However, when I upload the apk into the Android Market Place and download it onto the phone, the application downloads the database and then crashes, saying that the sqlite handler was not able to open up the database.
Here's the progression of code:.............

when i did, a playlist that has taken me the last two weeks to make disappeared. as luck would have it though it reappeared today for some reason. i would like to make a copy of it to save on my pc in case it decides to disappear again, but i can't seem to find the file. i made the playlist using the "Music" app that came with the phone. it's about 250 songs out of the 4.5 gigs i put on sd card.

I don't understand it. Yesterday I had 860 downloads and today I have 400. Why? How can the number of downloads decrease? How can I find the real numbers?

Would like to know, from someone who has tried it, if changing an Application's title in the Developer Console has any affect on the applications Ratings or Number of download statistics. In other words, will I lose anything?
My impression is no, but I don't recall if documentation says that explicitly or if its just implied. Would like to know from someone who has tried it. I don't want to experiment with my app.
Steps to change Title. Go to Developer Console->click link for the app->Look for Listing Details-> Change the Title ->click Save

I'm new to any touch screen phone technology and got my HTC Hero yesterday. I've played around with it and followed the instructions in the leaflet it came with. I have managed to use it to open up webpages including my usual email provider/facebook and have bookmarked them. I have inserted my numbers into the address book (and managed to sync with facebook for photos/birthdays), send SMS, make phone calls but that is it! In simple terms: how can I find apps and download them, does it always work through WiFi, how can I take things off the homepage (I have managed to install the (empty) playlist to the homepage but cannot remove it.

I love my Droid X. I downloaded PdaNet and paid for it. I received the receipt and clicked on the Pdanet tray icon and hit the register button. I wasn't smart enough to use copy and paste for the serial number and I typed it in instead. Tried three times (my typing isn't that bad) and all tries failed and the register button disappeared from the icon. I have tried to obtain help from PdaNet but no luck so far. The app is worthless to me if I can't access secure sites so I am ready to go in a different direction unless one of you can give me a suggestion for registering PdaNet.

I have started creating database for my application. It is working well. The data is also getting stored.But the issue is that i require dropping table, that already exists, every time i run the application.
But one thing i found is that whenever i change the version of the database in my code, the table gets dropped. But i would like to know whether it is possible to drop table without changing the version number of the database.

I am writing an app that will require a centralized database, along with a small app to digest incoming file data and populate this database.
android phone -> file -> some app somewhere -> some database somewhere
I know this is probably a fairly common situation. Is there a particular hosting service/solution for this? Many apps must do something like this (with high score tables and the like). The trick is, I can't use one of the high-score-specific hosting sites, because I need the app in front of the database to interpret the incoming files.

I'm testing an application I'm working on and I wanted to delete the database my application creates so I could read all the data from my web server back in to a fresh one.
I launched adb, went to data/data/my.applicaton.package/databases and did a "rm mydatabase". This deleted the database (note: I've done this many many times before without a problem).
I launched my application again and, to my surprise, a new database wasn't created. Even more surprising is there was data in my application. My application is still pulling the data from some where! It gets a Cursor from my database and uses a CursorAdapter to populate the list. So, it is obviously reading from a database (seemingly a cached one?).

I'm trying to implement a database in my application. I'm following a tutorial about writing my own ContentProvider, but I'm confused about SQLiteOpenHelper::getType. We're supposed to write it and, essentially, write a switch that returns the MIME type corresponding to the type of data we're dealing with.
I don't fully understand it. I'm not sure, even though I have an example, what is precisely supposed to be conveyed here. How do I determine the MIME type of my different tables of data?

I got some problem with my database in my Android application. Perhaps, my application is working but let me explain you.
Here are just parts of the code from my app.. i don't want to paste the whole it's not needed.
CODE:....................
So when i try to run my app i get Force close, but when i put manually: dh.insert("test", "ooo");
In the onCreate method in my main activity everything is fine and working. So, the conclusion is that i must put some value for the first time i run the app so it can work properly. I thought maybe to update that row with the new informations that i insert later through some TextView's from the app.

Basically I am creating a database driven website in Web Developer 2008. The database is stored in the App_Data folder of my website project. Could I have an iPhone, Blackberry, Symbian, Windows Phone, webOS or Android app access the database via an HTTP (or some other type of) request? I would like to know if this is possible before I move too far in the programming.

I want to create a sqlite database by importing data from some data files, like csv etc., and then put this database into one of my android application and then deploy into the Android device.
By now the samples and tutorial what I found are all taliking about creating the sqlite database at runtime when running the android application on the device. Is there anyway I can create it offline and then attach it to my application later?
Any tools and docs for this?

In one android application, I created a database file in data/data/com.rams/databases/dbfilename.
If I created a second application with the same package name (com.rams) and I access the database file created with my first application, the second application is able to access the database contents.
How can I secure the database file created with my first application?

My question is I think quite simple but I don't think the answer will be...
I have quite a lot of content to have in my application to make it run properly, and I'm thinking of putting all of it in a database, and distribute it in an embedded database with the application in the market.
The only trouble is that I have no idea of how to do that.
I know that I can extract a file .db from Eclipse DDMS with the content of my database, and I suppose I need to put it in the asset folder of my application, but then how to make the application use it to regenerate the application database?
