Excellent! I would certainly study AFWall. Thanks for the reference.
But actually, my quest doesn't stop here.
I am exploring Android, and Google's restriction of "UI to be built only via Java". (I am not interested in scripting and widgets for now, unless they are absolutely needed.)
I want to know the answers for same question (driver or app) for the following:
* Network Filter [EmptinessFiller, you already answered this as Java]
* Disk (SD cards) (for many various purposes) - file system should not block the intention, hopefully.
* USB filter
* SMS filter
I am still thinking of other categories. Will write more later.
Please suggest and refer. Thanks again!
