and i get the erro Failure install failed invalid apk

what’s the problem???/ please help me THX!!!

AND i’m sorry about my poor english

Are you using Unity 3.1? It should notice you about the incompatibility with device filter set to ARMv7; the emulator requires the experimental/universal device filter.

thx!! The problem has been solved

I have the same error :frowning: how it fixes?¿

how did ya solve this APK failure plx?

I believe he fixed it by setting the device filter to the “emulator only” setting.

Thanks a lot. I’ve been struggling with this issue for 72h hours… What a relief.

I got the same error on BlueStacks, it is because of incompatible Windows version, download this apk and install it: http://cdn.bluestacks.com/downloads/PackageFileInvalidIssueResolver.apk and you’re done.

I have downloaded the apk and reinstall the bluestack but still facing the same issue… please advice…

Unity 3.8 is quite old, can you update to a more recent version?
