1. Is there any stored procedure support in the sqlite database of Android? and any docs on doing this?

View 3 Replies View RelatedPlease direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
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.

View 2 Replies View RelatedI'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?

View 6 Replies View RelatedI am currently in the process of creating an application that records current location of a mobile device in intervals, displaying the route as a coloured line on the device in real-time. At the same time the application is storing the longitude and latitude in a SQLite database as I want the user to be able to bring up that specific route again.The route has a primary key and each waypoint is linked to that route by a foreign key. What would be the easiest way to display the saved route on the map?
View 2 Replies View RelatedI created a SQLite database on Android device. The program can read/write to database so the database file has obviously been created. The SQLiteDatabase.mPath is set to
db.mPath = "/data/data/dev.client.android/databases/clientDB.db"
but when I browse the directories on the device I can't locate the file clientDB.db. I looked inside data directory but it appears to be empty.Does anyone know what could be wrong here?

View 4 Replies View RelatedI am building an app which will let the user take a photo, then add some details which will be stored in a database. I want to be able to store some information (URI?) in the database so that when the user clicks the database entry from a listview it retrieves the photo. I hope it is clear what I want to do. Could I instead use a file path to locate the photo? Or do I need the URI? If I do need the URI then how do I get it?
View 3 Replies View RelatedHere is what I am trying to do:
- have a database that contains a word, and the name of an image file associated with that word.
- the words from the database will be displayed in a listview
- when the word is selected, a new activity will start displaying the word and the image in an image view.
Would it be best to store the terms in an array and have the list view populate from this array and then pull from the database onitemclick? Or can the list view be populated with the terms from the database?
Will android be able to display the image if the name of the file is stored in the db?
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.
View 9 Replies View RelatedI'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?
View 3 Replies View RelatedI 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?

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.

View 6 Replies View RelatedIs 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.

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?
