I made a game and tried to upload in google play store but it said to set my native code to 64 bit android. I searched for the solution in which I found out to check ARM64 in player setting but I couldn't find that check button. Could anyone help me..?
Based on this unity blog:
The move to a 64-bit Android world is imminent, and we at Unity
believe that it’s a good thing! We added support for Android 64-bit
with Unity 2018.2, and we have now backported it to Unity 2017.4. Read
on to get more details on Google’s 64-bit requirement, ARM 64-bit
advantages, and Android App Bundle support in Unity.

I started learning AR 1 week ago. I started building marker-based AR projects using unity and vuforia. But after installing the project apk in my oneplus nord, app is just showing black screen after asking for camera permission.
I searched about this online and found that it may be occurring because of vulkan, so I deleted it! But the same problem is still there!
I have spent so much time searching for a fix to this issue, it would be of great if someone will help regarding this!
This is probably related to Google removing ARCore support for 32-bit apps on 64-bit devices. You should switch the scripting backend in the project settings from 'Mono' to 'IL2CPP' and target both the ARMv7 and ARM64 architectures.
I have taken the "default game" (tables and chairs) of Unreal Engine 4.26, and packaged it for the Hololens emulator using these instructions.
I can launch the latest Hololens emulator (10.0.19041.1136) and install the Unreal application, and an icon shows up for it in the apps panel. But when I launch the app, the entire screen is black. When packaging the application for Windows (64 bit), the application works just fine.
What could be the issue? Older versions of Unreal Engine work fine, in particular I have verified that Unreal Engine version 4.25 works with the emulator.
Other perhaps relevant info: Intel Core i7-5960X, Windows 10 version 1909 build 18363.1440, NVIDIA GeForce RTX 2080 Ti, Version 456.71.
I have also used the Unreal 4.26-chaos engine, completely fresh. I choose a blank project from the Games category, C++, Scalable 2D or 3D, raytracing disabled, mobile/tablet with starter content. Then add the Microsoft Windows Mixed reality plugin and the Hololens plugin. In settings I get a signing certificate and define a project name, using Windows SDK version 10.0.18362. Again, no joy. The same thing, just as a Blueprint, not a C++ project, also does not work.
Also checked Hololens emulator version 10.0.19041.1117. No joy.
We followed all the steps exactly per docs including the “run in VR mode setting” in packaging and reproduced this issue today.
So, we are going to recommend to you to file a defect over with UE 4.26 via Unreal Engine Support | Get Help and Customer Service for UE - Unreal Engine. Besides, you can also open a support case via http://aka.ms/hololenssupport for free to discuss further too on anything we can offer for HoloLens 2 emulator/device:
The issue in the Epic's article. You should enable the "start in VR" option in Project > Description > Settings as from
https://learn.microsoft.com/en-gb/windows/mixed-reality/develop/unreal/tutorials/unreal-uxt-ch6
It was added in 4.26.
And we don't support Unreal 4.26-chaos yet. Please take simple 4.26.
I have a Unity project that I'm switching from APKs to AABs (app bundles). Previously, when I was building it as an APK, the Google Play Console told me the APK was 64-bit compliant.
Now that I'm building an aab, I'm getting the warning:
This release is not compliant with the Google Play 64-bit requirement.
The following APKs or App Bundles are available to 64-bit devices, but
they only have 32-bit native code
I have both ARM7 and ARM64 architectures set.
I am excluding x86.
When I open the .aab in an archive viewer, the lib folder has all of
the .so's for both arm64-v8a and armabi-v7a.
I'm using IL2CPP, .NET 4.x
I'm using Unity 2018.3.7f1
My ndk version is 16b
My
Android Studio is up to 3.4.2 and gradle is 3.2
A lot of similar threads here talk about following the "Learn more" links, which I've done. I had already done all of the work to get my app 64-bit compliant before switching to app bundles.
Other threads talk about Android Studio solutions, which I can't use because my automated build process involves building with Unity from command line, so it has to be Unity configurations or bust.
My expectation was the app bundles were supposed to be the hot new way to let Google build better APKs for you, but it seems like it's getting confused on whether or not aabs are actually 64-bit compliant, which seems to defeat the whole purpose.
Is this a Unity problem, does Google have an error in their system with regards to app bundles, or is there some other step I'm missing?
For those who have this problem since yesterday (August 19, 2019):
In Player Settings > Other Settings you must now uncheck the x86 box (It is for the 32-bit Intel architecture).
You will now only have the following warning:
The device types on which your application can be installed will be more restricted.
But, in my case, it drops from 12392 devices to 12385 devices.
Here is the opinion of a Unity member on the issue:
x86 is used by less than 0.4% of all Android devices, so it shouldn't have any real impact.
x86 target will be removed completely in Unity 2019.3.
It looks that there was a bug in the Play Console where this message was displayed even when the AAB was compliant. This should have been fixed last Friday afternoon.
Try again now.
I've been building a game in Unity using the Affectiva Unity SDK, and I can test the game out within Unity fine - the camera turns on, the SDK is called, and I get the response I was expecting.
Yet when I go to build the project, it claims it builds successfully and the camera is activated when the scene starts.. but I get no responses from the SDK. No errors or anything..
Do I need to package this up specially or something?
I suspect the issue is that you are building a 32-bit app on OS X. Is that correct? If it is, can you instead create a universal build or a 64-bit build? The Unity plugin currently only supports the following build options:
Windows 64-bit
Windows 32-bit
OS X Universal
OS X 64-bit (x86_64)
For some odd reason Unity defaults OS X builds to 32-bit. There is documentation about the build requirements on Affectiva's developer portal at the bottom of the page.
Can you please tell me, if vuforia can run on a PC? I have tried to make an .EXE file, but it does not work.
Please tell me how can I run vuforia apps on my PC? Should I build it for Windows store using Unity and then run it on Windows 8?
Can you please tell me vuforia can run on pc
Answer is No. You cannot build windows or mac app with Vuforia. Vuforia is only supported on Mobile Platforms (iOS, Android).
But you want to test on Windows, you can run your app and test in unity Editor mode with webcamera attached. I hope it will answer your question.
download unity from the unity website , install & run
download vuforia and vuforia sample for unity on vuforia website
create unity project and add vuforia package to the project
There are some tutorials for you for importing the samples and ofcourse you need to get a key with the name of your project.
Have a look at this https://www.youtube.com/watch?v=HnjbTytHH6U
For now, and without plugin, the answer is no. But,
Vuforia is work on supporting win 10, so maybe months later, you can develop a win 10 universal app.
There is some plugin support build the app for windows and Mac, it costs much money. The plugin is provided by maximarouf
As the answers above, I agree that it is enough to run in unity editor for presantation and test.
Vuforia now has a Windows 10 Early Access Program. You can apply for participation and may get access to the Windows 10 UWP SDK.
However, it currently only supports Intel based devices, like the Surface Book and Surface Pro series.
Alternatively, you can use the Unity3D Plugin to build an app which works on Windows.
No vuforia is not supported . U will get Vuforiawrapper.dll missing error when you try to .
Instead what you could do is , make an APK , Download Bluestacks and install it in PC and emulate your vuforia app in PC . But no Vuforia is not made for PC. It supports UWP though which means Windows Tablet , Windows Phone, Hololens .
