I'd like to add a feature to my android app that automatically backs up the sqlite database to the sd card.
What's the best way to go about this? Any examples/tutorials available?

I need to somehow backup my applitcations database to a file so that it can later be retored using that file. The only way I would do it would be by reading every table to an xml ffile but it seems soo ineficient. The data does not have to be humand readable.

I am working on a project for a belgium Tv Guide. Now I download a database (.db) file from a server to the sdcard to work with. In this database are 2 tabels, tvchannels and tvprograms. Now I can do several updates to the tvchannels table and i want to make a backup of this table to a lokal database file. How can i do that? I want to do this because I have to download a new database file every daye from the server and the channels that are choses are saved in the tvchannels database. I want to backup this database table and when the new database file (tvgids.db) is downloaded I want to replace the tvchannels database (from downloaded database file) with the backup from tvchannels..
View 6 Replies View RelatedI broke my HTC Desire so did what I thought was a backup to the SD card and sent it away to be fixed. Apparently they couldn't fix it and sent me another one. When I turned the new phone on (after having inserted the SD card) it asked me if I wanted to do system update, I presume this was to 2.2. I said yes. Now I have lost all my contact data (and diary but contact data more important!). If I connect my HTC desire to the PC I can see quite clearly the backup file I made before I sent the HTC desire off to be repaired. Questions is a) does it have my contacts in and b) how on EARTH do I put the contacts back into the HTC desire (sorry if I haven't phrased that very well).

View 6 Replies View RelatedIs it possible to take a csv file stored in the res/raw resource directory and use it to populate a table in the sqlite3 database? My thought was that, if there was a way to do a bulk import for the entire file into the table then that would be cleaner and faster than iterating over each line in the file and executing individual insert statements...
but I'm having trouble applying those statements in my Android application. My first thought was to try something like the following...but no luck:
db.execSQL("CREATE TABLE " + TABLE_NAME + "(id INTEGER PRIMARY KEY, name TEXT)");
db.execSQL(".mode csv");
db.execSQL(".import res/raw/MyFile.csv " + TABLE_NAME);...............

View 1 Replies View RelatedI'm trying to start unit testing on my application (should have done so from the beginning). I've got an Eclipse project structure set up and everything seems to work well, but...
I'm subclassing SQLiteOpenHelper to access the application database. This works well for the application, but when using the same class in the unit tests, it writes to the same database as the actual application. This is obviously rather irritating, since unit test data shows up when developing and testing the actual application.
What's the best way to make the SQLiteOpenHelper class write to a different database file when being called from the unit tests?
I know this is possible but I'm not really sure where to start. Has anyone been able to achieve this?

View 1 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?
