Android __ open helper to open database and get a cursor to pass to cursoradapter
I have a ListActivity that uses a CursorAdapter to fill the rows in the view. Database error I wrote a database helper class that gives me back results for common queries I make for my app, and it uses an SQLiteOpenHelper implementation I wrote to open the database. Database functions I use the open helper to open the database and get a cursor to pass to my CursorAdapter.
The problem I’m having, that I didn’t have before I implemented the open helper (before I just opened the database directly without a helper), is when I click on an item, which takes me to another activity, and then go back to this activity.
Top 10 data recovery When it initializes everything is fine, and my list is populated fine, but when I go back from the activity that follows, the list is empty and in the LogCat I see “Invalid statement in fillWindow()”.
It appears from a few post I’ve seen that the reason is, when I requery the cursor, the database is closed. Database job titles But I’m not closing it! I’m scratching my head on this one. Data recovery linux live cd View 2 Replies
I am writing an app that has a single database file with 3 tables ( AudioTable, PeopleMap, ImageTable) and am looking at 2 design alternatives:
1. S pombe database A -single- database adapter (myDBAdapter.java) which uses a database helper class that extends SQLiteOpenHelper. Database usa The adapter class has separate methods for accessing and updating rows in each of the 3 tables. Data recovery pro license key ie.

2. Icare data recovery 94fbr 3 different database adapters for each table all using the same db file.. Image database 1. Database web application audioDBAdapter.java, 2. Database graphic peopleDBAdapter.java, 3. In databases a category of data is called a imageDBAdapter.java) Each adapter uses it’s own db helper class (extending SQLiteOpenHelper)
While option 2 offers better encapsulation of the 3 classes (and corresponding data), I’m wondering if there couldbe a performance overhead or does the SQLiteOpenHelper implementation handle this without much overhead ?
Or is there some other way I can get better encapsulation with option 1.
