Only works for arm7 about unityoculusandroidvrbrowser HOT 9 OPEN

@Jamesfleming1
I found a fix for the application crashing on ARM64.

I was able to get around this issue fairly easily by deleting the GeckoView ARMv7 plugin from the project files and replacing it with the ARM64 plugin marked with the same version number.

At the time of writing, the correct file to use is "geckoview-arm64-v8a-80.0.20200818235255.aar" from the geckoview download page.

From my experimentation with the browser plugin, the build doesn't actively use the GeckoViewPlugin folder included in the repository -- I can delete that entire folder and the project builds/runs as expected. I think you'd have to recompile the plugin after changing the specified version number in order to see a difference, but just replacing the file with this specific version is a way to fix the issue without doing a deep dive like that.

Hope this helps.

Hmmmm I know that I only included the gecko engine library for arm7. You can download the engine for other architectures here. I don't remember any specific reason why the plugin might not work other than that. Will the Oculus SDK work with other architectures?

Hmm okay. I downloaded the .aar from https://maven.mozilla.org/maven2/?prefix=maven2/org/mozilla/geckoview/geckoview-arm64-v8a/90.0.20210705185941/, put it into the proper folder in unity.

Then I changed the build.gradle in GeckoViewPlugin/app/build.gradle to have
implementation "org.mozilla.geckoview:geckoview${geckoviewChannel}-arm64-v8a:${geckoviewVersion}" with the proper geckoviewVersion

However building my unity project it still crashes... Am I missing something? Do I need to build something outside of unity? something from the GeckoViewPlugin?

Here are my error logs, looks like it can't find "libmozglue.so"

from unityoculusandroidvrbrowser.

Hm if that's not a library you can include like I did here (those are libraries the gecko engine asked for) you could try asking in Bugzilla about that error when using their library in Unity.

from unityoculusandroidvrbrowser.

Where did you get those libraries? All I did was switch out the .aar file but maybe I need to switch out all of those libraries to arm64 versions. I didn't see any of those files where I got the .aar from https://maven.mozilla.org/maven2/?prefix=maven2/org/mozilla/geckoview/

from unityoculusandroidvrbrowser.

I don't remember exactly where I got them but from a quick google search I see they're available to download (common-1.1.1.jar. Have you tried searching for libmozglue.so?

using gecko version 80 seems to work for me

Do you mean the latest version (98) in my PR #43 ?
