[BUG]: WebView doesn't load #70

Open h1toru opened 2 weeks ago

h1toru commented 2 weeks ago

Version

v1.0.0-245-50fd798-release

Modules

ReZygisk by The PerformanC Organization version v1.0.0 (245-50fd798-release)

Description

After installing the module, any WebView-based app (like browser) doesn't load, it doesn't shows anything. Clearing the app data, reinstall the app, and using different system webview (like Google WebView and AOSP/LOS WebView) does not fix the issue. The issue fixed by removing the module.

Probably related to: #34

Steps to reproduce

  1. Download ReZygisk module from Actions page (specifically this
  2. Install ReZygisk module on KernelSU (v11872)
  3. Reboot
  4. Open any WebView-based app

After a little bit of test I can confirm that this issue can be fixed by disabling "Unmount modules by default" in KernelSU Manager.

Off-topic, but this problem also occurs with ZygiskNext with "Enforce DenyList" enabled in ZygiskNext WebUI and "Unmount modules by default" enabled in KernelSU Manager.

Browsers doesn't use WebView, so I'm afraid it is not connected to that issue.

Either way, enforcing denylist shouldn't make it crash WebView. A solution is to not include those apps in DenyList, I guess.

Browsers doesn't use WebView, so I'm afraid it is not connected to that issue.

Some browsers does. For example, Via Browser, which is the one that I use. Some apps also uses WebView for certain components like About and/or Help page that are most commonly used in e-commerce and banking apps.

Either way, enforcing denylist shouldn't make it crash WebView. A solution is to not include those apps in DenyList, I guess.

Of course those apps should not be included in the DenyList (and it never does), but if "Unmount modules by default" option is enabled in KernelSU Manager, DenyList will act as whitelist/allowlist instead of blacklist/denylist, which means that all modules are unmounted for all apps except the one that are allowed. Now the problem is that this issue is not fixed even if you allow Android System WebView to mount or access modules (disabling Unmount modules for Android System WebView app in KernelSU Manager), the only way to fix it is by disabling "Unmount modules by default" for all apps, which is strange because WebView is the only app that doesn't working.

You can try posting logcat, but I'm no WebView specialist.
