我试图打包一个包含对Armv7a的支持的项目，但由于它抛出了异常，所以无法成功。我能够成功地打包为arm64，如果我取消选项在包装项目窗口中的虚幻引擎4.27.2。

我也在互联网上进行研究，但根本找不到解决方案，他们提出的解决方案是使用"-fno- exceptions“一起禁用异常，但这似乎也行不通。

为.so构建armv7的错误如下所示：

由于arm32包错误，我目前只能支持数量有限的设备。

android

c++

error-handling

unreal-engine4

armv7

根据UE4文档，正确的解决方案是适当的兼容性。

UE引擎v4.27.2支持NDKv21.4e，我之前尝试使用v23.0。在下载并更改为v21.4e之后，我能够成功地为armv7a设备编译。
