Qt connection for andriod

[kasmax]

Hi guys
I need some help i have been trying it for so long but failed to resolve it.
I have created a small application in Qt for andriod that works fine on desktop.
byt when i deploy it to andriod device the connection show its connected but fails to read or write from sqlite database.
i have tried all including qstandard paths, etc.
below is my connection code:
bool connOpen()
{
mydb=QSqlDatabase::addDatabase("QSQLITE");
//mydb.setDatabaseName("C:/Users/Kas/Documents/KFinance/KFinance.db");
mydb.setDatabaseName("KFinance.db");

if(!mydb.open())
{
qDebug()<<("Not Connected");
return false;
}
else
{
qDebug()<<("Connected");
return true;
}

}


it it possible that i copy the sqlite database manually to phone storage location or sd card and then what will be the code to connect it?


i will be thankkful if someone can modify my code above so that it can connect to sqlite db in say phone storage\MyTest dir.


many thanks for your help

I've no idea what 'qt' is (QuickTime?) and this forum is primarily for Access which will not run on an Android device.

I expect that a specialist forum exists that would be more suitable for this question.
Good luck

Yeah, I would go elsewhere for real advice, but here's my near-ignorant advice:

mydb=QSqlDatabase::addDatabase("QSQLITE");
//mydb.setDatabaseName("C:/Users/Kas/Documents/KFinance/KFinance.db");

I've used QT and SqlLite on the raspberry pi, when I connect to a database that doesn't exist (because I mistyped the location or filename) it creates one in the exact location that I told it to look. That may be whats happening with you.

It doesn't find your database so it creates and connects to a new blank database. So, its shows connected, but when you perform a specific task (query specific table) it fails because that new blank database doesn't have any tables.

So, I would check your path to make sure its correct for android.
