Question

Sorry I am a noob, I am trying to learn about sqlite databases using linux, I cannot find any tutorial that covers what I need from setup to creating to using. At the moment tutorials I find say open a shell using adb shell command but when I open a terminal this does not work even if I navigate to the android tools folder, I can get the sqlite command working but the tutorials dont explain how I use it. For instance, how do I store urls and map coordinates and how to I reference them.

I have tried to use the firefox plugin but I havent got a clue what it all means and every tutorial says sqlite database is easy but it seems so complicated…….HELP!!!!

P.S would it be possible to create the data within the application code, I have seen some apps that do this

Does anyone have a set up guide and tutorial that can help?

Answer 1

To set up your database :

The recommended method to create a new SQLite database is to create a subclass of SQLiteOpenHelper and override the onCreate() method, in which you can execute a SQLite command to create tables in the database.

To use it :

You can execute SQLite queries using the SQLiteDatabase query() methods, which accept various query parameters, such as the table to query, the projection, selection, columns, grouping, and others. For complex queries, such as those that require column aliases, you should use SQLiteQueryBuilder, which provides several convienent methods for building queries.
