Question

I really need to create a small DB for doing only SELECT querys in my app. Because of that I would like to know:

1. Does android provide something for design and fill a DB? I mean no programming. Something like phpmyadmin so I could fill it and make a relation between 2 tables before running the app in an emulator or a phone.
2. If I create a DB, will it be visible from some file in the user mobile phone? Because I read in android manual that it was invisible but in some places I read that it’s saved in the mobile… I would prefer that this DB would be like a resource like it can be a layer or a string.
3. If I really need to create a DB each time the app is displayed for present the same information always, could I just “upload a sample” of that database in one line of code or so?

I need this for display a big list of items (maybe 2000 items) in different languages. I could do that just creating an array string resource but I need to order the list in a different way depending on the location of the user. At the end I need to retrieve an “ID” of the items selected but because it’s impossible to do a 2D array string as a resource then I can’t assign a number to the items so I can only know their positions in the list. The problem is that if I alter the items I will have a mismatch of positions numbers as ID.

This array is for an autofill text. I know I can put a comma after each item with the number and before adding this array to the autofill do a split and select the first column for the autofill and the second for compare position to real ID but I thought it would have a better performance to have all in a DB. Am I wrong?

You can use Sqlite Browser to create a database

 2. If I create a DB, will it be visible from some file in the user  
     mobile phone? Because I read in android manual that it was invisible
    but in some places I read that it's saved in the mobile... I would

    or a string.

It depends on where you create. Usually if you open a database it will be created in /data/data/[yourpackagename]/databases . This folder is incaccessible in normal cases, but if you have a rooted phone you can access this folder. Also while creating you could change the path to sdcard which is accessible everytime

  3. If I really need to create a DB each time the app is 
     displayed for present the same information always, could I just "upload a
    sample" of that database in one line of code or so?

You could store the db in assets folder of your app and open it.

Edit:

If it is just a 2D array i think its better to save as a csv and extract. You could put it in assets or raw folder.
