Soft keyboard is not visible on Android with Qt 5.15 on any input

Question

We migrated from 5.12.9 to 5.15.2 and now soft Android keyboard is not visible (does not popup) on active focus for any of our inputs or text fields. Is it a bug (QTBUG-88069) or some workaround exists?

Following Stackoverflow solution or setting/clearing window flags does not work for me.

Answer 1

So the problem was obvious because of following lines:

#ifdef Q_OS_LINUX
    qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
#endif

Changed to

#if defined(Q_OS_LINUX) && !defined(Q_OS_ANDROID)
    qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
#endif

as on Android both constants are defined: Q_OS_LINUX and Q_OS_ANDROID. And voila: Android keyboard works! :)
