Open a SQLite file and read it with `openDatabase`

I tried to open a new database like that :

localFileName = 'open-streets-dc.mbtiles';
db = window.openDatabase(localFileName, '1', 'my', 1024 * 1024 * 100);

It will create a new db in Web SQL and I can browse on it with chrome. In my case, I have to read an exisiting SQLite file but I did not found the solution.

I tried sql.js but I need to make it works with an Android, with ionic and it does not work as you can see in this issue.

Do you have an idea of solution?
