Android Question (Fixed) Error 14: Could not open db

[Emme Developer]

Hi to all, i'm trying to initialize a db in File.dirInternal (copied from assets) but i got this error:

android.database.sqlite.SQLiteCantOpenDatabaseException: unknown error (code 14 SQLITE_CANTOPEN): Could not open database

This is the code i use:

If File.Exists(File.DirInternal,DB_NAME) Then
        sqlManager.Initialize(File.DirInternal,DB_NAME,False)
    Else
        File.Copy(File.DirAssets,DB_NAME,File.DirInternal,DB_NAME)
        sqlManager.Initialize(File.DirInternal,DB_NAME,False)
    End If

I think is right because is a shared sub that I use in all my projects... So i don't understand the issue.
File in assets exists. Also in DirInternal.. I know i can use DBUtils to copy file, but i need to understand why i'm getting this error

Thanks to all

I was just going to post that I deleted the table called: progress and then it worked fine.
Also, you have columns in that table with data type as STRING. I have never seen that before. I usually put TEXT. Is STRING a valid data type in SQLite. Apparently, it is valid. You learn something every day.

Yes, the column All is in progress, i discovered the issue when i tried to delete progress and it worked fine as you write.
Usually I also put text, this time I put string out of carelessness, I've resumed mobile developing and sqllite after 2 years without doing nothing. But right point of view, the difference is here https://stackoverflow.com/questions/11938401/difference-between-text-and-string-datatype-in-sqlite

Lessons Learned from this thread (at least for me)
1. It is better to create the database and its tables via B4X code rather than create it via a PC program and load it to device. The exact error would have been displayed in the log as opposed to a an ambiguous error like error 14 generated when the database was created on the PC.

2. It is most generally advised as in a case similar to this thread to include a copy of the database or better yet the project for other members to help debug as opposed to making others write a multitude of guesses that prolong the thread

3. Not a good idea to name a table name or column ‘All’ as it is a reserved word in SQLite among many others. But if you insist on using ‘All’ in a column name add, say 1 to it like this: ‘All1’

4. Not to use STRING as data type but preferably use TEXT, although STRING can be used and does not generate an error, but with a cautionary measure.
