I dunno about the shader errors, but what if you add qputenv(“QML_IMPORT_TRACE”, “1”) at the beginning of main.cpp?
It looks like the material style etc. plugins are deployed, the QML engine just can’t find them when it tries to import them.

I cannot deploy a single project using QtQuick Controls 2 on android. The same project runs on windows classic and winrt. Other projects without QtQuick Controls 2 do run on android. The encountered error messages for the quickcontrols2 gallery example are: Warning: QML import could not be resolved in any of the import paths: QtQuick.Controls.impl Warning: QML import could not be resolved in any of the import paths: QtQuick.Controls.Material.impl Warning: QML import could not be resolved in any of the import paths: QtQuick.Controls.Universal.impl Although this may sound harmless, as it's just a warning, the resulting program will not run. With host GPU turned on, a white display is shown and the application output window shows: W System : ClassLoader referenced unknown path: W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/platforms/android/libqtforandroid.so: is missing DT_SONAME will use basename as a replacement: "libqtforandroid.so" I Qt : qt start W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/bearer/libqandroidbearer.so: is missing DT_SONAME will use basename as a replacement: "libqandroidbearer.so" D OpenGLRenderer: Use EGL_SWAP_BEHAVIOR_PRESERVED: true D : HostConnection::get() New Host Connection established 0xab124270, tid 2699 D : HostConnection::get() New Host Connection established 0xaeb87330, tid 2712 I OpenGLRenderer: Initialized EGL, version 1.4 W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick.2/libqtquick2plugin.so: is missing DT_SONAME will use basename as a replacement: "libqtquick2plugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Layouts/libqquicklayoutsplugin.so: is missing DT_SONAME will use basename as a replacement: "libqquicklayoutsplugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Controls.2/libqtquickcontrols2plugin.so: is missing DT_SONAME will use basename as a replacement: "libqtquickcontrols2plugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Controls.2/Material/libqtquickcontrols2materialstyleplugin.so: is missing DT_SONAME will use basename as a replacement: "libqtquickcontrols2materialstyleplugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Controls.2/Universal/libqtquickcontrols2universalstyleplugin.so: is missing DT_SONAME will use basename as a replacement: "libqtquickcontrols2universalstyleplugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/Qt/labs/settings/libqmlsettingsplugin.so: is missing DT_SONAME will use basename as a replacement: "libqmlsettingsplugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Templates.2/libqtquicktemplates2plugin.so: is missing DT_SONAME will use basename as a replacement: "libqtquicktemplates2plugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/qml/QtQuick/Window.2/libwindowplugin.so: is missing DT_SONAME will use basename as a replacement: "libwindowplugin.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqdds.so: is missing DT_SONAME will use basename as a replacement: "libqdds.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqgif.so: is missing DT_SONAME will use basename as a replacement: "libqgif.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqicns.so: is missing DT_SONAME will use basename as a replacement: "libqicns.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqico.so: is missing DT_SONAME will use basename as a replacement: "libqico.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqjpeg.so: is missing DT_SONAME will use basename as a replacement: "libqjpeg.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqtga.so: is missing DT_SONAME will use basename as a replacement: "libqtga.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqtiff.so: is missing DT_SONAME will use basename as a replacement: "libqtiff.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqwbmp.so: is missing DT_SONAME will use basename as a replacement: "libqwbmp.so" W linker : /data/data/org.qtproject.example.gallery/qt-reserved-files/plugins/imageformats/libqwebp.so: is missing DT_SONAME will use basename as a replacement: "libqwebp.so" W Gallery : (null):0 ((null)): libpng warning: iCCP: known incorrect sRGB profile D : HostConnection::get() New Host Connection established 0xa07f0320, tid 2713 D : HostConnection::get() New Host Connection established 0xaeb88140, tid 2718 W Gallery : (null):0 ((null)): QOpenGLShader::compile(Vertex): Vertex shader failed to compile with the following errors: W Gallery : ERROR: 0:2: error(#101) Macro redefined: lowp W Gallery : ERROR: 0:3: error(#101) Macro redefined: mediump W Gallery : ERROR: 0:4: error(#101) Macro redefined: highp W Gallery : ERROR: error(#273) 3 compilation errors.

No code generated and so on... I am running this example on Windows 10. Do I need to change my environment or is this a bug? All bugs having similar content did not quite describe what I am experiencing. Thanks for an help!
