After installing Droid Wall on a rooted Android mobile phone device, by default all applications are blocked, restricted and prevented from access Internet or networked location via both cellular data connection (2G or 3G) and Wi-Fi wireless connection.
Unless user switches to “Black List” mode, which all apps is allowed and permitted to access data networks except apps that are explicitly blocked, Droid Wall will work in “White List” mode, where users need to select apps and services that they want to allow to access mobile data connection, Wi-Fi or both mobile data and wireless network.
Tip: Black list does not block system processes, as only installed user applications can be selected, so there may be bandwidth been used by system processes to access Internet via GSM or CDMA data networks or Wi-Fi when available.
No matter in White List or Black List mode, there are certain apps that have multiple components that should not be blocked or restricted via Droid Wall’s rules in order for the apps to work correctly. For example, even if Market (for Android Market) is white-listed, the browsing of apps and games on the Market is working fine, but the Market app won’t start any downloads. Instead, the downloads are hanged and not progressing.
In order to for Android Market to work properly, the following applications must be allowed (in White List mode) or not blocked (in Black List mode):
Android Market: Market, Media Storage, DRM Protected Content Storage, Download Manager and Google Search (Enhanced), Google Settings Provider, Google Talk Storage, Google Apps, Goggle Talk Storage, Gmail Storage, com.google
Some other apps also use multiple apps or services to connect to remote services to work properly. An example is Gmail, which relies on a main Google service to authenticate.
Gmail: Gmail or Google Mail and Google Search (Enhanced), Google Settings Provider, Google Talk Storage, Google Apps, Goggle Talk Storage, Gmail Storage, com.google
Some media streaming apps such as Youtube and Spb TV (or Starhub TV which based on it) also requires Media Server service to be unrestricted.
Video Streaming (Youtube): The Media App and Media Server
Note: The name of the apps may be different depending on version of Android
