Upgraded to Qt 6 and Android Extras is gone

Obsess

I just upgraded to Qt 6 for better Qt Quick 3D support and noticed that Android Extras (which I'm dependent on for simplified JNI interop) isn't included. Searching around I found this:

Code from these Qt <platform> Extras modules will find new homes in more relevant modules over time, and any remaining APIs considered for inclusion in later 6.x releases (https://wiki.qt.io/New_Features_in_Qt_6.0)

Is there any way to get Android Extras back without waiting for an future Qt 6 release? Or, is there an alternative that I'm not seeing built into Qt 6 already?

Hi,

One possibility you can try is to build the module by hand with your Qt 6 installation.

_2020_

I am having the same problem. (Android project that worked in Qt 5.15.2 is now failing in Qt 6.0.0 due to missing androidextras).

@SGaist, do you have any tips for how one would go about building the module by hand and then incorporating into an existing project in Qt 6.0.0?

SGaist

Clone the module and use the usual qmake/make/make install trifecta.

Note that I have not tested that. It's just a suggestion.

Is there any recommendation or a way to run native code like when using QAndroidJniObject in QT 6? To be honest i am quite confused now. What is the official advice to do when porting apps to QT 6 using such modules? I'd expect some kind of replacement.
By the way, do I understand correctly your suggestion, doing this? I have tried:

git clone git://code.qt.io/qt/qtandroidextras.git
/.../Qt/6.1.0/gcc_64/bin/qmake qtandroidextras
make

and got this:

make[1]: Entering directory '/.../src'
make[1]: Nothing to be done for 'first'.
make[1]: Leaving directory '/.../src'

According to Qt Wiki (https://wiki.qt.io/New_Features_in_Qt_6.0), Qt Android Extra will no more be available:

Code from these Qt <platform> Extras modules will find new homes in more relevant modules over time, and any remaining APIs considered for inclusion in later 6.x releases:

Qt Android Extras

Qt Mac Extras

Qt X11 Extras

Qt Windows Extras

It sounds rather like it will be part of a later Qt6 release.

For me, I sounds like it will be merged/moved somewhere else, and maybe with API changes.
Which means, for me, QtAndroidExtras will disappear.

@jsulm Qt 6.1 first Alpha is now available, and in the not yet complete changes overview (https://wiki.qt.io/New_Features_in_Qt_6.1), you can find this

QtCore
Added QJniObject and QJniEnvironment as public API (mainly used for Android).

So it seems that QtAndroidExtras will be merge into QtCore :)

you should also follow discussion here:
https://bugreports.qt.io/browse/QTBUG-89482
https://bugreports.qt.io/browse/QTBUG-84382 (together with some referenced bugreports there)

I'm waiting for Qt 6.2 to be able to transform my mobile apps for Qt 6

Thank you @ekkescorner and @KroMignon
Seems like 6.2 will be the solution for many related problems.
