Android Emulator(AVD) host file
hosts file is same as Linux system. In Android, /system/etc/hosts is hosts file.
This is for emulator, we cannot change real device(if you are root, you can do it!)
How to copy file to local machine
Use adb (platform-tools), to access emulator, you need to run emulator first.
adb remount adb pull /system/etc/hosts/ c:\hosts
remount is needed before executing this command
If you want to edit, please be careful character encoding and line break.
adb push c:\hosts /system/etc/hosts
adb shell cat /system/etc/hosts
