Unity project with c++ dll 32 bit - Google Play Store 64 bit requirements

[Tomasz Woźniak]

Hi,
I have Unity project with DLL prepared for architectures: x86, x86_64, armeabi-v7a. I haven no possibility to convert DLL to architecture arm64-v8a. However if I build apk for armeabi-v7a only, it works on 64bit device. But for Google Store I need to build it with arm64-v8a compatibility - this version of application doesn't work because there is error that 64 bit DLL not found.

Is there any possibility to solve this problem? Maybe there is some possibility to modify apk file after build (i.e. it would pretend 64bit package, but works as 32 bit)?

And why is it working on 64bit device when build with ARMv7 setting in build?

Thanks in advance for help.

Try to ask for source code of dll then compile for your target device or ask the author of dll for build your target device.
