Hi all,

Is it possible to use Necessitas (Qt for Android) with Lazarus? I mean if anyone tried or if it could work :)
it's simply curiosity (for now: I don't have android devices)

Regards,
Kjow

I don't think anyone has seriously tryed.

An interesting interview about necessitas: http://www.behindkde.org/node/925

It seams quite interesting, seams that he used the Surface API and custom-draws widgets. I bet it will have serious issues with all the wierd virtual keyboards and fonts one can find out there in various devices.

Besides the GUI, Android encapsulates multiple Phone-specific functions and provides the as a high level Java-based API (such as dialing, GPS, ...) How to access same when doping a native code application with a QT GUI ?

There is something called Qt Mobility which should be an abstract API around generic phone features. At the moment it isn't implemented for Android, but in a unknown future it could be.

At the moment you need to call the Java APIs, which for C++ apps actually means that the Java part of the application needs to do those calls.

Android Qt apps are not 100% native, they also need a Java side. The objective here was being able to write the GUI in C++, therefore requiring less Java, not removing the Java side (which is impossible).

Is there already a C++ library plus the appropriate "standard" Java stub-set for C++ ?apps that are supposed to run on Android via QT ??

Yes.

Will there be ?a Lazarus "Widget Type", and a set of LCL API calls plus the appropriate "standard" Java stub-set for fpc ?apps that are supposed to run on Android via QT ?? :-)

It might exist when someone contribute that =)

Note that at the moment I am working only in Pascal apps which use the Android API.

I supposed it would be this way.

Thanks, it would be very interesting with Lazarus.
