[SOLVED] Blackberry 10 prevent device to go to sleep mode

Blackberry 10 prevent device to go to sleep mode

Sorry, but I am new in blackberry 10 development basically I am a Android developer looking for an API in blackberry 10 which prevent my blackberry 10 application to go to sleep mode. I want my screen active forever.

In my application I am using socket communication using QTcpSocket which is not working ones device go to sleep mode.

Solution

C++

#include <bb/cascades/Window>
#include <bb/cascades/ScreenIdleMode> 

//... 

Application::instance()->mainWindow()->setScreenIdleMode(bb::cascades::ScreenIdleMode::KeepAwake);

Or QML

Page {
    onCreationCompleted: {
        Application.mainWindow.screenIdleMode = ScreenIdleMode.KeepAwake
    }
}

I haven't played with TCP a lot, but I believe it is supposed to work even though the app is minimized, not in foreground or even with screen shutdown, make sure you have the Run as Active Frame permission checked in your bar-descriptor.xml file. Many of my apps use UDP and they work fine even if they aren't in foreground.
