How to run application in background?

Ibrahim

Hi; I want to run my application in background for desktop and mobile. How can I do that? I know JNI for Android but I am asking: There is a class or namespace in Qt to running in background? Thanks.

Hi,

What kind of application do you have in mind ?

Trilec

Hi Ibrahim,
you may want to look into QProcess, its used to start external programs and to communicate with them. (through communication is more complex if its a detached background task ie. QProcess::startDetached.

There are meany options for controlling its behavior...

hope that helps

@SGaist I want to learn power of Qt for mobile and desktop. Provision for android is Service and this.
@Trilec thanks, Is running in background this member function?

SGaist

A service like in Android and a desktop service are currently quiet different even with Qt to help these are really two different concepts.

What will your service do ?

@SGaist I want to learn that concepts. Example is application update own database in background. (Example image to running in background.)

Then I'd recommend to take a look at KDAB's Qt on Android Episode 7 article as well as the ones before.
