Hi! I'm developing a offline web app and it work very well with Android 4.4 >, but my employer need it's to work in a old 2011 tablet with Android 3.2, so I came to indexeddbshim. It has about 20 tablets with this awesome version.
I'm using dexie.js.
My code to starts with that:
When I force the shim to work the app works well in current Chrome on Windows, but inside the Webview of Android 3.2 I get the following error:

Any tips?
