Is there a option to build 64 bit APK with Unity 2017.3.1f1?

I have a apk that was built with Unity 2017.3.1f1 a while back and it has been on Playstore for some time now. With the recent changes that google are making or planning to make, I'm trying to rebuild this with 64 bit support.

Everything I've read online advises to go to player settings, change scripting backend under other settings from mono to IL2CPP - after this apparently I'm supposed to get an option to check a box titled "ARM64" under target architectures but I'm not getting this option.



Am I doing something wrong or is it just not possible using this version of unity? If not, any ideas on what the best workaround is?

thanks in advance for any suggestions

 

Thanks for the reply. I've updated it and tried to build but am now trying to resolve a new error for the past few days. When building and selecting ARM64 it gives me the following errors

and then says it has built successfully but there is no apk in the selected location.

I've tried a few solutions that have worked with others such as restarting the computer, reinstalling the NDK and making sure NDK location path does not contain whitespace but nothing seems to be working :-/

 

Hi, apologies for the delay. Was just trying a few different things out.

So it seems I can build ARM64 if I import the game into unity 2018 but doing this messes up the physics and causes more issues than it resolves.

The requested Editor log is below.

Would really help is anyone can set me in the right direction. I have no experience with ARM64 so am grateful for any help.

 

Hi @aleksandrk , @Tomas1856 ,
I have some problem on arm64 architecture ,
I make a build with ARM64 architecture that is working very slow(lagging) on android device, and i also make a build with ARMv7 architecture that is working perfectly.
So what should we do for that?

Unity version : Unity-2019.2.0f1
ndk version : android-ndk-r16b

 

Thank You So much ,
That is working for me

 

This Solution working sometime,
after sometime lagging problem occurs..

this is not a permanent solution of lagging for arm64 architecture.

 

Yes i'm tried, but profiler rendering going to up when application is running on android.
while i make simple 2d game, then why it occurs?

 

Yes.

Is it solved ?

I am having the same issue (using 2019.4.1f1), the app runs without the slightest FPS drop on ARM7, yet ARM64 gives like 10-15 fps. Is there a way of resolving this issue without upgrading to 2020.1? (like indicated here https://issuetracker.unity3d.com/is...the-project-is-built-with-64-bit-architecture)
