In QML how to set Image bytearray in Android?

[J.Hilk]

@mikeeeeee
might actually be an endian error, where do you get your Bytearray from?

[Mikeeeeee]

It's errors:
W linker : Warning: "/data/data/org.qtproject.example/qt-reserved-files/plugins/imageformats/libqgif.so" has unsupported flags DT_FLAGS_1=0x80 (ignoring unsupported flags)
W linker : Warning: "/data/data/org.qtproject.example/qt-reserved-files/plugins/imageformats/libqicns.so" has unsupported flags DT_FLAGS_1=0x80 (ignoring unsupported flags)

How to fix this?

[Mikeeeeee]

I do in C++ screen, translate it into QImage and translate in Bytearray

How to fix this?

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

[Mikeeeeee]

Yes, I need an Android.

@mikeeeeee For which platform were these libraries build?

[Mikeeeeee]

For Android.
armeabi-v7a (Clang Qt 5.13.0 for Android ARMv7)

@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 ?

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);
//qDebug()<<QWidget::winId();
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?
