Here is the error output for the android apk

...libbitcoin-qt_arm64-v8a.so: qrc:/qt-project.org/imports/QtQuick/Dialogs/DefaultFileDialog.qml:45:1: module "QtQuick.Dialogs.Private" is not installed                             

It looks like expected considering https://github.com/bitcoin-core/gui-qml/blob/1e9981df75b559596e8f9386858ec3f147124634/src/qml/bitcoin.cpp#L55-L57
