Question

I m considering writing an internet filter app for Android which would allow parents to block objectionable web sites on their children s phones. I m assuming this would also be useful on GoogleTV when it comes out. How would I even start? Is it possible to block access to specific sites without requiring the user to root their phone?

I m guessing I could do it with iptables, but that would probably require a rooted phone.

Edit:

If the phone was rooted, how would one go about doing this? Are ip tables the way to go or is there a better way?

Answer 1

Sorry, an application can t do this.

Answer 2

Given you can find isAllowed(Url) you can use WebView to load a new page. Although as I write it, you might want a more powerful browser than WebView, http://androidcommunity.com/forums/f4/how-open-a-new-screen-to-display-a-web-page-141/ might be helpful.

Answer 3

You can set an intent-filter for some url (using http scheme). By this way, if user browser on an identified url, your app will be launched instead of the webpage.
