Android :: Loading SQLite Database Into App

Jun 10, 2010

I am able to create, write and read an SQLite Database in my Android App. I have a copy of the Database that is fully populated with data, and I want to get that data into the App's Database. Is it possible to access my populated database from inside my App? Or can I at least create a copy of the populated database and then use that copy? Or do I need to do a .dump and put all the inserts into the Android code?

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 :: Using My Own SQLite Database

Feb 13, 2009

I'm new to Android, I just finished the Notepad Tutorials, where we can create SQLite Databases to save notes. So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.

Android :: Database - XML Or SQLite?

Mar 25, 2010

I'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?

Android :: Use Own Sqlite Database?

Mar 5, 2010

I put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?

Android :: Delete Top Row In SQlITE Database

Aug 2, 2010


public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}

It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.

Android :: Necessary To Close SQLite Database?

Jul 22, 2010

Is it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.

Android :: Prevent Access To SQLite Database

Oct 18, 2010

I use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?

Android :: SQLite Database Slow Insertion

Aug 17, 2010

I need to parse a fairly large XML file (varying between about a hundred kilobytes and several hundred kilobytes), which I'm doing using Xml#parse(String, ContentHandler). I'm currently testing this with a 152KB file.During parsing, I also insert the data in an SQLite database using calls similar to the following: getWritableDatabase().insert(TABLE_NAME, "_id", values). All of this together takes about 80 seconds for the 152KB test file (which comes down to inserting roughly 200 rows).When I comment out all insert statements (but leave in everything else, such as creating ContentValues etc.) the same file takes only 23 seconds.Is it normal for the database operations to have such a big overhead? Can I do anything about that?

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 :: Sharing SQLite Database Between Activities

Jun 24, 2010

I'm in the middle of writing myself an app and have run into a problem concerning the use of the same SQLite database within multiple activities.

I have one activity that is used to input and store data and multiple activities that need to then read that data. Within the first activity, it has no problem inputting the data into the database, but when I go to have the other activity read the data, it tells me the database is empty. Obviously I'm doing something wrong in my handling of this shared database.

Right now, I have a DataHelper class that handles everything. In each activity, I create a DataHelper object which then calls the openOrCreateDatabase() method. I then close the database upon exiting the activity. Obviously this isn't the right way to do it.

So, my questions is, what is the correct way to set up an SQLite database in an Android application and then access it in multiple activities?

Android :: Populating Spinner From SQLite Database

Feb 3, 2010

I'm attempting to make a dynamic drop down that will be filled by a SQLite table. I have a Cursor object which I can pull the data I need from. I've been able to accomplish loading the values into the drop down with the code below:

CODE:..............

My problem is that I need the a selection from the drop down to also contain the RowID of the item selected. I need to be able to select one item and have access to the value of that item in the back end. For example, think of a drop down in HTML. Each drop down selection has it's own hidden value that is pulled. I need this value to be hidden for me to allow me to know which ID they choose.

Android :: Maximum Size Of SQLite Database

Aug 14, 2010

I have a SQLite db that size is over 2.6 GiB. (The db contains maps.)

This db is used by RMaps app. When move the maps to some parts at maximum zoom, the app suddenly closes.

However, there is no force close message, no report button. So, I've got an idea that it is caused by reading blocks that are beyond a certain limit e.g. max(int). Since RMaps is just using simple SQL statements, I think that the problem is not in RMaps but rather in Android SQLite driver.

Is there a size limit of SQLite database on Android?

(I have Froyo on Nexus One, but I do not think that this is just a problem of Froyo.)

UPDATE: Log output:

CODE:.......................

UPDATE2: The SQLite db is stored on SD card, there is enough space.

Android :: Data Not Inserting In Sqlite Database

Aug 14, 2010

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.

this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.
