Qt + Android and WiFi

Qojote

Hello,

I am writing an app for an android device and i am wondering if it is possible to enable and disable the Wifi within my app?

Best regards

Hi and welcome to devnet,

I haven't tested that with Android but the Bearer Manager might be what your are looking for.

Hope it helps

Hi,

Yes, i read the article. When i run

QNetworkConfigurationManager manager;
const bool canStartIAP = (manager.capabilities()
                              & QNetworkConfigurationManager::CanStartAndStopInterfaces);

canStartIAP is false. My app has all permissions to edit the wifi state.
Furthermore, wheni try the following code:

 QNetworkConfigurationManager ncm;
 QList<QNetworkConfiguration> nc = ncm.allConfigurations();

foreach( QNetworkConfiguration item, nc )
{
   if (item.bearerType() == QNetworkConfiguration::BearerWLAN)
  {
     qDebug() << "Wifi" << item.name();
     qDebug() << "state" << item.state();
  }
}

then i see that my app knows that there exist a mobile and wifi network but the state is alway 0x2.
I am also able to use androidextras to run java code and use the wifimanager to switch on wifi (which works), but it would be nicer to use Qt-Code only...

Best regards

From a quick look at the code, it seams that changing the connection state is currently not supported so you are on the correct track using the QtAndroidExtras module

Thanks for your advice.
I've got one more question:

On my Android device the QNetworkConfigurationManager only lists "Mobile" and "Wifi" but not the names of the available WLANs. Does this have to be done externally as well?

SGaist

Did you call QNetworkConfigurationManager::updateConfigurations ?

Qojote

Yes, i did.

SGaist

Which version of Android ?

Qojote

My device runs android 5.1.1 and i am using Qt 5.5.1.

SGaist

Since Qt 5.6.0 is out, can you check again with it ?
