This mod allows to use /system/etc/hosts file on configurations/ROMs (mostly symlinked hosts file on Android 4.4+) where it is ignored.
Hosts file usually gets ignored on some ROMs due to SELinux restrictions if it is a symlink to file on different partition.

Technically it works by attaching to all packages/apps and hooking DNS resolution API. On first name resolution API call hosts file is read and stored in memory (in HPPC OpenHashMap structure).

Additional features of hosts file:
  • use of IP address 127.0.0.0 allows to fail name resolution of associated hosts
  • use of DNS names instead of IP addresses (these DNS names are passed directly to DNS resolver - they are not looked up in hosts file recursively)

Known limitations:
  • JNI libraries are not affected (some applications may still ignore hosts file)
  • hosts file is read in memory of each application when it makes first DNS query (time and memory used depends on size of hosts file; time is logged in logcat with tag "hostsEnabler")

hosts Enabler uses HPPC: High Performance Primitive Collections for Java library which is distributed under Apache License 2.0.

This mod requires Xposed framework to be set up and hosts Enabler enabled as Xposed module.
