I want to have a list of restaurants with information such as addresses and phone numbers in my app. I also want to be able to edit this information after the app is published. What is the standard way for doing this? Would I need to use a SQLite database?

How do I store and retrieve a byte array (image data) to and from a SQLite database in Android?
View 1 Replies View RelatedI'm working on an Android application that stores data in a SQLite database. My question is, where does this database file get stored on the filesystem when you're using an emulator?
I have seen that it's stored in /data/data/package_name/databases
But I need to know where on my local machine's hard drive that actually maps to. The database persists on multiple runs of the emulator, even after having shut down the machine, so it can't just reside in RAM...
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?

Is it possible? If it is, how to proceed? On the Blackberry platform, I am able to store objects directly in persistent objects. Is it possible to do this with SQLite and Android?

View 3 Replies View RelatedIf I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?
View 2 Replies View RelatedI 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.

View 1 Replies View RelatedI want to store location data in sqlite. A latitude coordinate is a double, with 15 point precision. As far as I can tell this corresponds with the 'REAL' datatype which is 8 bytes. The alternative I suppose would be to store it as a String, and simply convert it back into a double later. Does it make any odds which way I go? Are there differences in storage capacity / efficiency?

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.

View 3 Replies View RelatedIn my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.
