External cache for WebView to load?

Question

I'm using WebView in my application and I need to pre-cache some webpages for later use. Since I want the caching process be less obnoxious, it have to be unnoticeable. So it's better to be implemented in a Service.

I don't know how to achieve this because WebView can only exist in an activity. Is there any method to cache webpages to local storage, and let WebView load it later? Or how can I realize the features with another approach?

Answer 2

As long as the Web pages don't call LocalStorage.clear before they exit the data should be available in a SQLite database.

If my memory is correct is under 4.03 the path is something like /data/data//app_database/localstorage/file__0.localstorage

As the local storage data is saved in a SQLite table called ItemTable you can read this data using the SQLite APIs (when in the same context).

So you could pre-populate the table from your service by inserts into this table.
