We've made a mistake. I immediately ask the text QString image("data:image/png;base64,"); And so, pictures of the there is no. Need another code.

Mikeeeeee

qDebug() <<"image.isNull() :" << image.isNull()<<"screen->size() :"<<screen->size();
return
image.isNull() : false screen->size() : QSize(360, 640)

Hi
Not all android devices can take shot of QML. Need support in openGL driver.

Hmm. your Qt version seems new enough.
if you google "qt qml grabwindow bug" you can see there been quite some issues but
it should work with new Qt versions.

How type of android device are you using ? I mena is it old or kinda new ?

Mikeeeeee

I use Android 5,6,9
