I can solve the problem. First, I created folder sqldrivers including libqsqlite.so in the app directory (e.x. /data/user/0/com.example.polarislib) and I set permission by chmod 777 to sqldrivers folder and libqsqlite.so file and finally I used the following code in my source where the connection to Sqlite is needed:

QCoreApplication::addLibraryPath("/data/user/0/com.example.polarislib");

Unfortunately it didn't work. I still get the same value. Any other suggestion?

@Qjay said in QtAndroid local notifications , notifications poping up immediately:

the notifications are popping up almost instantly ( despite me providing time for it ).

you pass the time you want it to be triggered from now on. The API expects a time since EPOCH (as your comment in the code also states) which are the milliseconds from 1970/01/01 on.
So in your JAVA code add new Date().getTime() milliseconds to your current timeout.

So far i am able to get the notifications ( but not on Android O )

did you read this already?
Alos chekc the Qt debugger console and/or LogCat for suspicious messages regarding notifications.

I meet the same issue. My problem is solved by these steps:

select "projects" in left tool bar of Qt creator. click "cancel" icon of "Make install" in Build Steps. click "cancel" icon of "Build Android APK" in Build Steps.

The click actions look not operating at all, but after these clicks, the project is allowed to build.

I run in the same paradigm when I try to create a static linked library with Qt targeting Android and latter to use it with JINI on Android Studio.
Reading you post I see you have almost the same problem like me with one difference.
To me are working as far I use only std library
My problem appears when I use QString for example in the library.
Looks the static build does not statically includes the Qt framework dependencies.
Finally did you find a solution? Me I run with this issue past over one month.
Thanks
