Alert: HTML local storage unexpectedly being deleted on Android

Last week Google started rolling out a new version of the Android WebView with a bug which deletes site localstorage after app startup.

Roll-out was halted at around 50% and the Chromium team are currently working on resolution. More information to follow as it becomes available.

Symptoms: Any data stored in localstorage is missing after the webview has been updated and the app started up.

Affected WebView version: 79.0.3945.79

Fix: Update to a newer version of the WebView.

More information:

The Chromium team have committed a fix.

It looks like the impact will be:

  • Users who upgraded to the affected version will regain their old data but lose any new data saved to local storage during the interim.
  • Users who did not upgrade will remain unaffected.
