View 2 Replies View RelatedI'd like to use an existing sqlite3 database created outside of the phone, on a computer reachable by Wifi. I know how to download the file using Socket. The problem I see is that android.database.sqlite classes access databases only in /data/data/<package_name>/databases and it does not seem to be possible to write files directly in there. Is there a way to write a file in /data/data/<package_name>/ databases or ask the android.database.sqlite classes to read a database from another place?

View 1 Replies View RelatedI have this database file under the usual databases folder and a bunch of tables inside it. Please note that I don't want to retrieve under the command line. I know I can use the ".tables" command. I want to retrieve a list of all tables in it, using code, so that I can execute some specific algorithms on each of them. Also, I didn't find any questions with this problem on Android, so please forgive me if there is any. I was wondering if there is any function I can use under Databases, but I didn't find any either.

I'm using a SQLite database to store information on players and their teams using android. I've got it working so that all the players I've created will show up when ever I start my program, so the database is working. So far, so good. However, whenever I try to retrieve the rowId of a player from the database, it always gives me 0 back. This surprises me in itself, since I'd think I'd get an error if I wasn't accessing it from the cursor correctly, but instead it gives me 0. After debugging for a while, I realized that the Player object (not in database) also wasn't saving the id correctly, although it was finding a value for it. This was corrected when I set the id after creating the object, although it seems I would be able to set it in the creation statement itself. Curiouser and curiouser. Code...
View 1 Replies View RelatedI need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?
View 2 Replies View RelatedMy GNex took a baseball to the screen; the screen is shattered and unresponsive, but the phone will power on and I can see the file structure if I connect via USB to my PC. I've retrieved all the files and photos that I want to save from the phone by copying to the PC, but not the text messages. I had a backup for the text messages, but it's gone (different story for another time). So I've been searching for a way to retrieve these text messages that can be executed entirely from the PC side, since I have no way of installing an app on the phone. I'd either like to be able to copy the SMS database to a new phone via PC, or dump it into some sort of manageable text format.
From the searches I've done, it seems like I might be able to do this using some sort of developer's code; (i.e., Install this program, plug in the phone, enter these lines of code, etc.)
The phone is stock (not rooted), and was just recently updated to ICS 4.0.4 (?)
Samsung says they can "fix" the phone for $160+, but that they won't be able to save any of the data since the phone isn't navigable (I assume they'll just send a replacement).

I have a listview that is populated by a couple threads that pull in data from the network. Before that data comes in, there are some default values displayed. When the screen loads, there are 6 items displayed, each with the default data. The 1st (index 0) loads and is updated on the screen, and then number 6 (index 5) is updated with that same info. Then, item 2 (index 1) loads, and then item 5 (index 4) mirrors that data. Then item 3 loads, then item 4 reloads with the correct data, then then item 5 with the correct data, then item 6. Why are items 5 and 6 briefly showing the data from other elements in the list? I can't figure out what in the world could be causing this.

View 3 Replies View RelatedI have the following code to intantiate a SimpleCursorAdapter to use with a ListView. As you can see I have passed the R.layout.log_item to display the list items, and one value/control to bind to (TripDate).
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.log_item,c,new String[] {DBAdapter.KEY_LOG_TRIPDATE},new int[]{R.id.txtTripDate});
This works. I currently only have one widget in the layout xml, a TextView to hold the TripDate.
How do I pass multiple binding parameters for the additional widgets in the layout? So I can also display other info.
