Android includes a database engine (SQLite). In general, do the applications keep/manage their own databases (files) or is there a unifying database manager?

I have some external sqlite files I'd like to include with my app. It looks like I can add them to the /assets folder, then read them from there? Is the /assets folder the appropriate location for them?
I've used SQLiteOpenHelper to open databases my app creates at runtime, which just uses a unique db name. Will the sqlite files in the assets folder also be accessible using SQLiteOpenHelper in the same manner?
Is there any tool that will allow me to browse databases on my Android device? Something like Sql Management Studio - you know GUI tool that displays databases, tables, row in tables, etc.
I'm using Eclipse for development (if it is important for plug-in suggestions).
I'm trying to work with a web service (that I have no control over) that returns a SQLite database when you query it. Is there any way to do this?
View 3 Replies View RelatedI read some stuff about SQLite databases to use them within my own application. so for this point, it should work.
BUT:
for most of my data stuff i need a database that i can directly put into my application. i read on stackoverflow that it's possible to put up to 1,2mb files in the assets folder and then copy them anywhere else to use them.
my question is:
is it possible to acces those databases in the assets folder directly to read from them? there's no need to insert data into this database, it's just a data storage to read from? is it possible? and if it is than how could i do this?
I dont know why but somehow my adt didnt create any database folder.Here is the code i used :
package com.example.test;
import android.app.Activity;
import android.database.Cursor;[code]....
My problem is, i cant find databases folder from file explorer through DDMS.
Is there a way to programatically get the path to the databases/files an application uses instead of hardcoding "data/data/mypackage.com/database.db" ?

Open (getWritableDatabase)in OnStart and close in OnStop in each Activity?Open in OnCreate and keep open til the user quits the app (where would you put close?) Open, do work and close as soon as possible each time it is needed?

View 2 Replies View RelatedLets say that I have an app that lets you browse through a listing of cars found in a Sqlite database. When you click on a car in the listing, it'll open up a view with the description of the car and a photo of the car.My question is: should I keep the photo in the database as a binary data column in the row for this specific car, or should I have the photo somewhere in the resources directory? Which is better to do? Are there any limitations of Sqlite in terms of how big a binary data column can be?The database will be pretty much be read only and bundled with the app (so the user wouldn't be inserting any cars and their photos).

View 2 Replies View RelatedI'm using SenseHero and in the past I've restored nandroid backups a few times. I've also wiped the phone before restoring a backup.But after I've used Titanium to re-install apps, the manage applications shows apps that have been uninstalled. When I select them in manage applications, I get a FC.I've investigated a bit, and it seems manage applications thinks the apps are still installed for some reason. If I find the app in Market, then Install and uninstall it, it no longer shows in Manage Applications.Is there a way to force a refresh of Manage Applications? I don't want to have to install/uninstall all the rogue aps.The main reaons for wanting to sort this, is so that when I backup/restore from Titianium, I don't have this issue and I can create a Nandroid backup that is correctly up to date.
View 1 Replies View RelatedAfter installing a new rom I checked the 'keep my phone backed up with google' check box and it started installing apps that I hadn't used for ages. Now I dont want these apps so I reflashed and didnt tick the box but my question is, is there a way to view a list of the apps that are backed up and possible delete some of them from the computer?
If not, what is a way to manage these? Im guessing that I could start with a fresh rom, let it install the backed up apps, then manually uninstall them and let it sync back again - would that work?
I was using the facebook app and clicked a youtube video link and decided to make youtube the default app to launch for this specific action. However, I later decided that I want it to launch the link in a browser (so I can read comments) instead of playing instantly after clicking the link.
I tried "Clear defaults" under settings>applications>manage applications but there is no settings for youtube. I tried to clear defaults for facebook and my browser, and tried reinstalling the facebook app but no luck.
I used to be able to clean my cache from settings manage apps filter ETC... but now with 2.2 I cannot , anyone know how ?
View 5 Replies View RelatedI'm a very happy KaosFroyo 37 user, but I have some misc questions.(sorry, this item is a sort of double-post) Do any of these lockscreen widgets work with Froyo? When I was running Android 1.5 and 2.1, I would keep my screen pattern-locked most of the time, since it lives in my pants' pocket and I want to avoid it activating accidentally. Then when I get into the car and place my phone in a cup holder, I would unlock the phone once and click a widget which would leave it unlocked (for easy access to GPS, etc.) for the duration of my ride, when I would lock the phone again and put it back in my pocket.Now with Android 2.2 I can't do this with the lock pattern, because apparently the security mechanisms don't permit it; one must re-enter the lock pattern several times, which is very time-consuming. Is there another approach for 2.2 users? I don't need very strong security, just want to avoid accidental phone calls and other accidental activations.
While (Android's) Manage Applications worked for me initially, now it only works the first time after a reboot. I.e., I can run it once, but on any subsequent attempts it will hang while attempting to populate its app list. As workaround I purchased Quick App Clean Cache, which is nice in its own right, but it would still be nicer not to have this problem. Also I'm not 100% convinced that Quick App Clean Cache is always giving me the complete set of options for an app, e.g. to move it to an SD card. Have others encountered this problem? I could probably generate a logcat for debugging purposes.
Most apps will let you move them to the SD card in KaosFroyo 37, even though I haven't checked the CyanogenMod option to permit these.I guess that there are a few more apps which might copy more completely to the SD card if I used this option.Can anyone shed any light on this option and whether it's saves any memory, and whether it induces any instability?I'm always careful not to copy widgets to the SD card.Battery life is a continued mystery; clearly much worse than before I rooted. Apparently the CPU tweaker isn't recommended (I guess it uses too much battery life trying to figure out whether it needs to adjust the CPU speed), and the battery life tweaker on the XDA forum described doesn't provide a very clear strategy. What do folks recommend? [ Correction: I had read a pretty incoherent writeup somewhere on XDA, but now see Collin_ph Battery Tweak RC1 for Cyanogen / Darch Froyo roms (possibly others) - xda-developers which is well-written. I will try this approach, but welcome your experiences.
Maybe some of you know but this is for those that don't, you need the below Download this software to your PC and install it http://www.fjsoft.at/en/highlight.php Install this app on your phone [url]
Turn on USB Debugging then connect your phone via USB to your PC don't Mount the SD Card then run the program you installed It syncs Outlook 2007 contacts I don't know about earlier versions though check the settings and set advaned options the way you want Sync Outlook to phone Sync Phone to Outlook Sync both You can tick ones in the list that yo do not want syncing Explore how this works before you do any full syncs so you know its doing what you want You can also Messages - inbox, outbox, draft Apps - Start, Delete, also Install from your PC Files - Phone, SD Card Calendar Alarms Calls - Missed, incoming, outgoing

I am developing an application for android phone, In this I need to use at least 400 audio file which can
be played for some respective texts,Now my question is which is the optimized way to do this.One solution is putting all the audio files in the resource folder and referring from there, this will never be a feasible solution as the application size will increase. Is there any way to convert the audio file into some format and dump into the SQLite database and retrievr flexibly.
I've made a few apps now, which use an SQLite database, no problems. In my latest app, I want two tables, and I just released that every example I can find only creates one table. So, is this a limitation? Must I use only one table? Assuming I can use two, how do I go about changing my create script?

Lets say Im creating an Android app for a company that already provides some sort of online service. I want my android app to extend this online service and I want the app to interact with my remote databases, would I embed a web browser in my application or directly connect to my remote database from within my code? If I am directly connected to a database from within code and not through a web browser, would that be a security risk since the connection info would be distributed in the code?

Can anyone tell me, is it possible to use the ADB to pull and push a database from an app, without root privileges on the phone? For example, I know the location on my rooted magic and dream is:
/data/data/com.xxxx.xxxx/databases/xxxx
I know that you can use ADB without root, but when trying to use the shell - you can't view that location without root privaliges. But I have been told you can use push and pull if you know the file you want? Basically I want to pull a database from MY app on a non rooted phone modify it and push it back on. Only trouble I have is, the two phones I have are both root and I don't have access to a non root one to try it out.
