Subject Maintaining App Data When Switching WebViews
Date Thu, 12 Feb 2015 20:46:52 GMT
Worth a discussion about this, I think.

If you have an app already launched that uses localstorage/websql, and want
to switch to xwalk, how can you migrate your data?

What if you want to use system webview for API >= 21 and xwalk only for old
phones? Then you need to move data in the reverse direction.


Idea 1:
- See if sqlite / localstorage databases are the same format, and provide
code that migrates db locations

Idea 2:
- Use wizcorp's multi-window plugin to create a new an off-screen system
webview, then use post-message to read data out of the old one.

WDYT? Is this a problem we need to solve?
