Issue Details

Steps to reproduce:

1. Load AGa
2. Wait for OS to or manually kill Android Webview

Expected Behavior

• AGa shouldn't load Android Webview unless Private Browser is currently being used, & should unload it immediately after
• AGa shouldn't crash if Webview is killed

Actual Behavior

• AGa constantly runs Webview
• If Webview is killed, all of AGa goes with it

Screenshots

No screenshots possible? Just the disappearance of AGa suddenly when Webview's killed.

Additional Information

This might be a real solution for @snhv's #5518.

@TPS Thank you for reporting!
This problem reproduces on our side as well. The crash will be fixed soon.

Unfortunately, the Webview start is currently can not be moved to the Private Browser start phase due to technical reasons.

Unfortunately, the Webview start is currently can not be moved to the Private Browser start phase due to technical reasons.

So how's this planning to be fixed? The OS may unload WebView anytime it wants & perceives it's not actively being used. If it does, will Private Browsing cease to work until AGa itself restarts? This seems… weird.

@Numci I just installed v4.7n59, which changelog says fixes this. Unfortunately, it fails the exact same way as above. What now?

[maxikuzmin]

@TPS please update to RC 2, version will be released soon, we fixed this bug

[TPS]

No, all versions since AGa Private Browser is introduced (pre-v4.7n57 through v4.8n5 inclusive) still crash identically — this is not fixed!

[cyberboh]

For me, it is not resolved even in 4.8n3, AdGuard crash / closes whener WebView updated / closes.

@Versty @maxikuzmin Please re-open this issue.

@Numci @maxikuzmin @Versty When should we expect an actual fix to test?
