Android :: Retrieve A Database From Network
Jan 27, 2009
I'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?

I want to store Location objects into my database, and then be able to load them. How can I build a Location object from its attributes? Should I create a blank Location and then set the attributes? (If yes, how?) Should I use my database as a Location Provider? (If yes, how?) Code...

I 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...

I 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?

My 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 been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I'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?

I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)

I seem to be seeing an issue with the data network access on the EVO. When it happens none of my applications get internet aceess and my mobile network status says "turning on". The only way I've found to fix it is to pull the battery. Any one else seeing this? If so is there a better fix than pulling the battery?

My eris has always has pretty alright battery life, what I would expect out of a smartphone, if unplugged at 9AM it usually was running on its last leg around midnight. I've had it for over 5 months now, I've always had it activated on alltel, I installed the 2.1v3 leak before the official OTA was out and just lately it seems like there something very wrong with my battery life...
If I unplug my phone at 9AM within the past week and occasionaly check and respond to a text message, my battery had been down to almost 30% by NOON... what?..
I have noticed that if I disable Mobile Network (3g/1x data), the thing lasts all day and some... If I turn mobile network ON, I can't see that I have any network traffic or any apps running in the background that are syncing data at all... I've had google account sync mess up on me before and have to reset my google account because it gets stuck in a syncing loop, but its not doing that, already checked. Very weird.
Anyone thing it could be something wrong in my ##PROGRAM#/##778# provisioning menu, maybe something got changed?.. Maybe it could be do to Alltel's AT&T merger that's happening right now, maybe some 3G tower's radios are turned off or something...

I have an android application using LocationManager get the cell network location and not the Wifi location? If I have turned off the Wifi antenna and do the following:LocationManager lm = (LocationManager) paramContext.getSystemService(Context.LOCATION_SERVICE);I am always returned the Wifi location and not the cell network location. I want it to return the cell location since I have moved fromthe Wifi location. I tried using a LocationListener but that doesn't seem to help.
