How can I access my localhost from my Android device?

Is it possible to limit 3G usage on an Android device to only a particular app such that no other app/browser has access to 3G?

• If I wanted to provide turnkey Android devices (hardware + ongoing 3G) to retailers but wanted to ensure that the device is not used for anything but the redemption app I have built, is this possible?

• Answer:

  Yeah, it's possible. You're going to have to download another app though. If you're phone's rooted, then DroidWall is what I'm using to blacklist certain apps from using 3G. I'm sure this would work for your situation too: https://play.google.com/store/apps/details?id=com.googlecode.droidwall.free&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5nb29nbGVjb2RlLmRyb2lkd2FsbC5mcmVlIl0. Otherwise, Onavo is a really nice app as well- you can limit wifi and 3G to certain apps and monitor data usage. https://play.google.com/store/apps/details?id=com.googlecode.droidwall.free&feature=nav_result#?t=https://play.google.com/store/apps/details?id=com.onavo.android.onavoid&feature=more_from_developer%23?t=W251bGwsMSwxLDEwMiwiY29tLm9uYXZvLmFuZHJvaWQub25hdm9pZCJd. Of course this is no 100% barrier, anyone savvy enough could just find the limitor app and disable it. This should help prevent that: https://play.google.com/store/apps/details?id=com.domobile.applock&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5kb21vYmlsZS5hcHBsb2NrIl0. Hope this helps.
