        Do you get this on Android?
        For which platform were these libraries build?

                @mikeeeeee I do this on my Android application, and it works fine (Android 7.1/7.0 and Qt 5.7). Do you have enabled multimedia support in you PRO file with QT += multimedia ?

                  Yes.
                  If i do dhis, I get screenShot: "data:image/png;base64,"
                  The program does not take a screenshot.

                  QImage myScreen;
                  //QPixmap pic = QPixmap::grabWindow(QWidget::winId(),0,0,50,50);

                  QScreen *screen = QGuiApplication::primaryScreen();
                  QPixmap pixamp;
                  pixamp = screen->grabWindow(0);
                  myScreen = pixamp.toImage();
                  //myScreen = quickView->grabWindow();
                  //myScreen.save("C:\\Users\\New Owner\\Downloads\\i.png");
                  QByteArray bArray;
                  QBuffer buffer(&bArray);
                  buffer.open(QIODevice::WriteOnly);
                  //myScreen.save(&buffer, "JPEG");
                  //QString image("data:image/jpg;base64,");
                  myScreen.save(&buffer, "PNG");
                  QString image("data:image/png;base64,");
                  image.append(QString::fromLatin1(bArray.toBase64().data()));
                  qDebug()<<"screenShot:"<<image;
                  return image;

                    @mikeeeeee So your real problem is not showing PNG but taking a screenshot? right?
