Requesting Android permissions in Qt 6

I am trying to convert a Qt 5 app to Qt 6. In Qt 5 we can request Android permissions as follows:

QStringList permissions;
//...
QtAndroid::PermissionResultMap resultHash = QtAndroid::requestPermissionsSync(permissions);
for (const auto &perm : permissions)
{
    if(resultHash[perm] == QtAndroid::PermissionResult::Denied)
    {
        qDebug() << "Permission denied:" << perm;
        return false;
    }
}

What is the equivalent in Qt 6? Or is the only way to manually implement this using JNI?

Regards

Here is the new Qt6 permission API (which is still under development, however can be used): QtAndroidPrivate Namespace

Example:

#include <QtCore/private/qandroidextras_p.h>

bool checkPermission()
{
    auto r = QtAndroidPrivate::checkPermission(QtAndroidPrivate::Storage).result();
    if (r == QtAndroidPrivate::Denied)
    {
        r = QtAndroidPrivate::requestPermission(QtAndroidPrivate::Storage).result();
        if (r == QtAndroidPrivate::Denied)
            return false;
    }
    return true;
}

There is no permission handling API in Qt6 yet. However, it is under making. You can follow the situation from QTBUG-90498. It looks like it is scheduled for Qt6.4 release which I assume will be due some time in the fall 2022. You can find a code review link from the bug report which might help you in writing your own implementation.

I would recommend you to take a look into QNativeInterface::QAndroidApplication::runOnAndroidMainThread which you can use for asynchronous calling on the Android UI thread.
