Android :: How To Use SQLite Database? (Create / Open)

Apr 18, 2010

I am trying to use

SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS));

To create/open a database instead of making use of the SQLiteOpenHelper (because I want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, I am getting this exception for that line of code:

04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed

04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:638)...

Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am I just using SQLiteDatabase.openDatabase the wrong way?) Would it help if I create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that I passed in?) If creating the file manually is the way to go, is it just an empty file, or do I have to write something to it?

Android :: Create A Standalone Sqlite Database And Then Put Into My Application?

Nov 4, 2009

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?

Android : Create A Sqlite Database That I Can Manually Input Data From My Computer

Nov 30, 2009

I have certain needs that I am having trouble making an app for. I was hoping to be able to create a sqlite database that I can manually input data from my computer and search the data on my droid. I wanted to set up tags or full data search within each sqlite database object so and pull up a listing of best matches for the given search term.

The use for it is that I work on an Air Force Base and my job is very broad. I wanted to custom build an app that I could list all of the information pertaining to my job and be able to search it as I work to find solutions to problems way quicker than we are doing it now.

Is there any such app. I've been trying to create my own and it looks like it would be a mix between notepad and searchable dictionary but not quite.

Android :: Synchronizing Sqlite Database On Android To A Sybase Database On Server

Apr 12, 2010

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?

Android :: Get Droid Database Setup?

Nov 20, 2010

Typically, for a WinForm or a Web App, I create the database and tables through the RDBMS or through a separate install process. However, I haven't seen anything of the sort in Android. All the examples I've seen have the database creation scripts embedded in an activity like this.

The best thing I can come up with now is to call a method from the data access constructor to check whether the database is installed - if not - install it. However, this seems like a lot of overhead to me.

What's the cleanest way to execute a android database install and then forget about it?

Android :: Random Complete Loss Of Database On Droid Only

Apr 22, 2010

Several Droid users have reported that my app's entire database just destroys itself randomly after a few days or so. This seems to be specific to the Droid. I'm at a loss. My app has a service that runs in the background to display notifications, it also supports widgets. Both of those (and the app itself, of course) access the database, and I marked every accessor to the database "synchronized", just in case. Any remote idea what could cause the entire database to just vanish?

Android :: Can't Increase Value Of A Record In Droid / Sqlite Database / How To Do

Aug 6, 2010

I try to increase the value of an integer key in a row in my table. However, nothing really seems to happen.

db.rawQuery("UPDATE table SET key = key + 1 WHERE name=?", new String[] {name});

However, this code works fine (just sets the key to a hard-coded value):

ContentValues values = new ContentValues();
values.put("key", 2);
db.update("table", values, "name=?", new String[] {name});

Also tried '?' instead of just ?, but it resulted just in a run-time error.

Android :: How To Embed A Database In .apk Of A Distributed Application [droid]

Jun 10, 2010

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?

Android :: Way To Deploy Large Database With Droid Application

What would be the best way to do this? Can I just stick the database in the assets folder? I have read of various limitations that apply to the entire application size and to individual resources within, especially on some devices... What are exactly these limits?

Is there any way to do this apart from a post-installation download from an external server?

Android : How To Add Manually Contacts Group To Droid Database?

Android : Setup Trigger On Contacts Database In Droid?

Dec 3, 2009

I have a requirement wherein I need a list of all the contacts that are edited/changed.

As per the Android documentation,

_SYNC_DIRTY

will be set every time a contact is edited. But, there seems to be a bug in this, which makes this always set to 1 (no matter what), even is we explicitly set it to 0.

So, I was wondering if I can create a SQLite TRIGGER on the contacts database. Such that, everytime a contact is edited, the edited contact id is populated into a different table which I can read later from my application.

I tried this...

CREATE TRIGGER IF NOT EXISTS updated_contacts UPDATE ON 'contacts.db'.phones
BEGIN
INSERT INTO updated_table SET updated_id=old.person;
END;

But a few problems here...

1) 'phones' is a table in the contacts database. but, I am not sure about the name of the contacts database (here I have assumed it to be 'contacts.db').

2) updated_table is a table on a different database 'mydatabase.db' that I have created from my application. and, I am not sure if I can set TRIGGERS across different databases.

All this in Android 1.6 Also, I am not sure about the permission to access native contacts database on Android.

Is there any other way of achieving this.
