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?

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 have an app with Admob ads on it but I find that when I use it the ad almost never refreshes because I don't change activities, instead I just update a text view when buttons are pressed. I have tried searching this on Google but keep comming up short.
I would like to tell the app to refresh the add occasionally, such as after two button clicks or something like that. Does anyone know how to do this and potentially have some sample code for it?

View 2 Replies View RelatedI 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.

initialValues.put(KEY_TIME, time);
db.insert(tableName, null, initialValues);
