Android 8.0 Oreo, Google pixel 2
Description
On an Android 8.0 (Oreo) device (Google Pixel 2), QUdpSocket failes to receive any broadcast packets.
Binding to port is successfull however and no errors show up in logcat.
Code is working as it should on all other tested Android devices.
Tested different UDP sources (our own, and Dropbox lan discovery). Tested on ports 17500 and 35353.
When testing on the same device but different version of an app (Not build with Qt but same UDP port), UDP discovery does work.
UDPBroadcastScanner::UDPBroadcastScanner(QObject *parent) :
QObject(parent)
{
}
void UDPBroadcastScanner::startScanning() {
qDebug() << "UDPBroadcastScanner::startScanning()";
qUDPSocket = new QUdpSocket(this);
bool bindSuccessfull = qUDPSocket->bind(QHostAddress::Any, 35353);
if (bindSuccessfull) {
qDebug() << "Successfully bound to port";
connect(qUDPSocket, SIGNAL(readyRead()), this, SLOT(readyReadDatagram()));
} else {
qDebug() << "ERROR: Failed to bind to port";
}
}
void UDPBroadcastScanner::readyReadDatagram() {
qDebug() << "readyReadDatagram" ;
}
