First, add few checks to your implementation (if you do not have those already)

// Ensure QSQLITE driver is supported
if (!QSqlDatabase::drivers().contains("QSQLITE")) { // Print something ... }

// Ensure QSQLITE driver is supported
if (!QSqlDatabase::drivers().contains("QSQLITE")) { // Print something ... }

To copy to clipboard, switch view to plain text mode 

And then you could try next way to access DB file:

mDB.setDatabaseName("databases/juicemania.db");

mDB.setDatabaseName("databases/juicemania.db");

To copy to clipboard, switch view to plain text mode 

Because the default folder is your private folder there is no need to access your files via applicationDirPath -method. And last thing is that after failing to open DB, print information about the error using QSqlDatabase::lastError maybe that will reveal more about what is the problem with the open.

Also in your case return value from

QFile::exists("databases/juicemania.db")

QFile::exists("databases/juicemania.db")

To copy to clipboard, switch view to plain text mode 

should be true if the file is in the correct location.
