[Interest] qt6: any QtAndroid::androidActivity replacement?

[Ivan Solovev]

Hi Alexander,

Since 6.2 you can use the static methods of QNativeInterface::QAndroidApplication directly.
See https://doc-snapshots.qt.io/qt6-dev/qnativeinterface-qandroidapplication.html#runOnAndroidMainThread for some code samples.

It should be enough to

#include <QCoreApplication>

for that.

For those who can be interested. Here is my current qt5androidcompat.h
file to ease the support of both Qt5 and Qt6. Here you can find how to
use new Qt6 API:

#pragma once

#include <QtGlobal>

#ifdef Q_OS_ANDROID

#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)

#include <QtAndroid>
#include <QAndroidJniObject>

using QtJniObject = QAndroidJniObject;

inline QtJniObject qtAndroidContext()
{
     auto result = QtAndroid::androidActivity();
     if (result.isValid())
         return result;
     return QtAndroid::androidService();
}

inline int qtAndroidSdkVersion()
{
     return QtAndroid::androidSdkVersion();
}

inline void qt5RunOnAndroidMainThread(const QtAndroid::Runnable &runnable)
{
     QtAndroid::runOnAndroidThread(runnable);
}

#else

#include <QCoreApplication>
#include <QJniObject>

using QtJniObject = QJniObject;

inline QtJniObject qtAndroidContext()
{
     return QJniObject(QCoreApplication::instance()
->nativeInterface<QNativeInterface::QAndroidApplication>()
                       ->context());
}

inline int qtAndroidSdkVersion()
{
     return QCoreApplication::instance()
->nativeInterface<QNativeInterface::QAndroidApplication>()
             ->sdkVersion();
}

inline void qt5RunOnAndroidMainThread(const std::function<void()> &runnable)
{
     QCoreApplication::instance()
->nativeInterface<QNativeInterface::QAndroidApplication>()
             ->runOnAndroidMainThread([runnable]() {runnable(); return
QVariant();});
}

#endif // #if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)

#endif // ANDROID
