About this app

aFirewall means Android Firewall. It allows you to configure multi rules to block different call or message at different time. Periodic rule and one shot time rule are supported.

---aFirewall basics---
☆ To make sure aFirewall has higher priority to monitor incoming messages, please install aFirewall before other third-party messaging applications such Go SMS Pro, Handcent etc.
☆ Black list is the default list to be blocked. By default, you only need to put the number into black list if you want to block it; Check on "Unknown and private" in black list to block unknown/private/restricted/anonymous calls;
☆ Number in protected list will never be blocked; Protected conversation supports to hide protected list numbers' call/SMS/MMS;

---What can rule do?---
☆ How to hangup call; Multi hangup mode are supported. You can forward the blocked calls to voicemail or a non-existing number. And you can set aFirewall to accept and hangup blocked calls to avoid forwarding to voicemail;
☆ how to block group lists; You can set Call Blocking lists and Message Blocking lists separately;
☆ how to response blocked calls and messages;

---aFirewall data---
☆ Support to backup all aFirewall data to sdcard directory with xml format; and restore aFirewall settings from sdcard directory;
☆ Based on BackupToEmail application, support to backup blocked log and protected log to Gmail;

---More features---

☆ Prefix wildcard supported;
☆ SMS keywords Block is supported;
☆ Support to block SMS message from Email address; But aFirewall does not support to block Email;

---Limitations---
☆ Following android permissions are only granted to system or signature applications by android system, based on these changes from Google, you maybe need to root your phone and convert aFirewall to system application to fix related issues in your phone although aFirewall tried its best to workaround them.
1). android.permission.MODIFY_PHONE_STATE: changed from android 2.3 and required by answerCall and cancelMissedCallNotification;
2). android.permission.WRITE_APN_SETTINGS: changed from android 4.0 and required by queryApnSettings to download MMS attachments;
3). android.permission.WRITE_SECURE_SETTINGS: changed from android 4.2 and required by on/off airplane mode;
☆ You can use free link2SD(free), apps2ROM(free) to convert aFirewall to system; and I will also release a related application to Google Play to convert aFirewall to system later;
