[jira] [Commented] (CB-6033) Android 4.4 update loses LocalStorage data

["Angela Fowler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CB-6033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14015204#comment-14015204 ] 

Angela Fowler commented on CB-6033:
-----------------------------------

For 4.3 the location is /data/data/com.xyz/app_database/localstorage/file__0.localstorage.
In the ItemTable, the key and value are both text.

For 4.4 the location is /data/data/com.xyz/app_webview/Local Storage/file__0.localstorage.
In the ItemTable, the key is text and the value is blob.

On a Nexus simulator the 4.3 app_database folder is still there in 4.4 but appears to be empty in DDMS. It is possible to return to 4.3 and obtain the old file on simulator. I don't have a device to try this on.

> This appears to be a result of the switch from old WebView to the new Chrome-powered WebView.
> If an app is installed in 4.3 and saves data to LocalStorage (and possibly to WebSQL) and then the device is updated to 4.4, that data appears to be lost.
