    It turns out that I had failed to copy my modified AndroidManifest.xml file, as qmake had copied the default manifest without the required permission tag. Make sure that you have included an assignment to ANDROID_PACKAGE_SOURCE_DIR under the android block in your qmake project file: android { QT += androidextras ANDROID_PACKAGE_SOURCE_DIR = \ $$PWD/android } I couldn't request the permission with QtAndroid::requestPermissionsSync because the underlying Android API method only works for dangerous permissions: android.permission.ACCESS_WIFI_STATE is classed as a normal permission.

    Sorry, I just saw there was a missing word in my phrase and fixed it. What do you get if you just show a normal unmodified QWidget object ?

    @jsulm said in Finally I have camera problem...: What do you mean? That was small mistake. I meant QOpenGLWidget but wrote about QML component. You should file a change request in Qt bug tracker instead. I have created QTBUG-80341 - immediately it have got level P2: Important. This gives hope for solution. And for same mark here. Now it's absence shows to Qt users - the problem persists yet.

    Delete the folder and use the classic qmake/make. Use the full path to the qmake you want to use.

    @pcman11 said in Reimplemented QOpenGLWidget shows under QStackedWidget.: @SGaist sorry, but I'm not allowed, it look like ALWAYSSTACKONTOP attribute is rejected, all OPENGL content is stored under all rastered content.. thanks :) it looks like platform-dependent specific issue, because it's only android's problem. i deducted that when last-child is openglwidget problem persists, but if last parented is raster widget-it content appears on top
