libhoudini: libwebviewchromium.so not found / SIGSEGV from libgallium_dri.so

[stef-15]

Hi, I'm a bit new to this, so any pointers would be great.

I've installed libhoudini and see the following issue come up, not sure if this is Unity-related. Browser works fine, so I'm a bit stumped. From waydroid logcat:

Maybe this isn't an issue with libhoudini, but more of an issue with the game, but just wanted to see if anyone has noticed it.

Things I've tried:

• I see libwebviewchromium_plat_support.so in /var/lib/waydroid/overlay/system/lib64/arm64. Copying the file to libwebviewchromium.so doesn't work. I can confirm libwebviewchromium.so is NOT in /system/lib/ even after this. I'm not sure how to get it in here since sudo waydroid shell is readonly.
• I tried updating SystemWebViewGoogle by installing it into waydroid, but it still cannot find libwebviewchromium.so

I see a similar issue in waydroid/waydroid#1206 , however my host isn't anything special, Intel i7 CPU.

Looks like you are missing chromium webview for android ! Have you installed Gapps package as well ? And let play store update it's components ?

The name of app causing this issue would be helpful in testing !

Hello!!
The OP said "not sure if this is Unity-related", which means it should have been an app made with Unity. Genshin Impact also has this issue (waydroid/waydroid#1206) and also heavily relies on WebView to render information and update logs.

Edit: the issue doesn't happen with Honkai Star Rail, Genshin's sister game, and also presumably shares a large amount of code (it is built in Unity and has a really similar UI). So the app is probably Genshin. It's also probably not something to do with Unity itself.

Adding a note for anyone who would find this useful, I don't think copying the file to libwebviewchromium.so will work. I found libwebviewchromium.so inside /system/product/app/webview/webview.apk. I'm not certain how dlopen fails to find it...

~/webview.apk$ ls 
AndroidManifest.xml  assets  classes.dex  lib  META-INF  res  resources.arsc
~/webview.apk$ ls lib
x86  x86_64
~/webview.apk$ ls lib/*/**
lib/x86_64/libcrashpad_handler_trampoline.so  lib/x86_64/libwebviewchromium.so  lib/x86/libcrashpad_handler_trampoline.so  lib/x86/libwebviewchromium.so
~/webview.apk$ 

Funfact: libwebviewchromium_plat_support.so and libwebviewchromium_loader.so does not link to any native chromium code at all, according to the Android source code. libwebviewchromium_plat_support.so provides the system interfaces allowing WebView to render and libwebviewchromium_loader.so provides the system interfaces required to load WebView.
