I have been able to display map on desktop, however after deploying it for android the application crashes.

Can anyone pls guide me on this?

Development System:
QT Creator 9.0.1

based on QT 6.4.0 (MSVC 2019)

Android JDK: 11.0.16

Android NDK: 23.1.7779620

Openssl installed.

Deployment Device:

Snapdragon 845

Android 10

Hi @TasawarAhmad ,

We are familiar with this problem. Unfortunately with Qt 6.4, the ABI was broken so our Map SDK libraries (built with Qt 6.2.4) do not work.

You should be able to get it working if you use Qt 6.2.x, or 6.3.

It is fixed in Qt itself, but not until 6.4.3. More details here https://bugreports.qt.io/browse/QTBUG-109428

Thank you. After downgrading to qt 6.2.4 everything seems to work.
