SMS Sieve

Filtro de SMS.

This is a simple, opensource SMS filter (see the source at https://github.com/prrt714/SMS-Sieve).

This app blocks SMS according to your rules. After you install it,

there is no rules, so you should create them first. This app can serve as either whitelist or blacklist. For example

you can add regular expression ".*" (less quotes) to blacklist

anything. Then you can add exceptions. If you add exception "\+[0-9]+"

(less quotes), it will not block SMS from addresses containing digits

following the plus sign (e.g. +1234567). Blocked SMS are swallowed by

the app and logged, so you still can read it.

It need not any additional services to run in backround.It just

registers itself as SMS receiver, so Android knows what app should be

first to receive SMS.
