嗨，

我正在学习集成QT与arcgis运行时api。

我已经能够在桌面上显示地图，但是在为android部署它后，应用程序崩溃了。

有人能指导我一下吗?

开发系统:
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。

部署设备:

Snapdragon 845

Android 10

Hi @TasawarAhmad ，

 我们熟悉这个问题。不幸的是，在Qt 6.4中，ABI被破坏了，所以我们的Map SDK库(用Qt 6.2.4构建的)不能工作。

如果您使用Qt 6.2，应该可以让它工作。X，也就是6.3。

Qt本身是固定的，但直到6.4.3才固定。更多详情请点击这里  https://bugreports.qt.io/browse/qtbug - 109428 < / >,, < / SPAN > < / P > Thu, 2023年1月5日18:23:28 GMT //www.gobook3.com/t5/qt-maps-sdk-questions/unable-to-display-map-on-android/m-p/1245729#M4825 JamesBallard1 2023 - 01 - 05 - t18:23:28z //www.gobook3.com/t5/qt-maps-sdk-questions/unable-to-display-map-on-android/m-p/1246126#M4826 < P >谢谢。在qt降级到6.2.4之后，一切似乎都正常了。< / P > < P > <跨类=“lia-unicode-emoji”title =“:thumbs_up: " > < / span > < / P > 2023年1月6日星期五18:22:15 GMT //www.gobook3.com/t5/qt-maps-sdk-questions/unable-to-display-map-on-android/m-p/1246126#M4826 TasawarAhmad 2023 - 01 - 06 - t18:22:15z
