Android emulator ignores settings in system/etc/hosts file

What I did. To work with testing api I need to add specific ip and host name into hosts file. So I edited config on my pc system/etc/hosts. After that I could use my host on PC browser.

Then I tried to open same host on Android Studio Emulator (same PC). And the browser shows error "webpage not available ... ERR_NAME_NOT_RESOLVED". Strange, because, I assumed the emulator would use PC OS hosts properties (like on Mac with X-Code emulator).

So I rooted emulator, changed it hosts file same way as on PC and rebooted emulator - the same error in browser.

It seems like Android Emulator ignores both PC hosts file settings and its own. How to make emulator work with my host ip-hostname pair? Maybe I missed something?

The last line in the devices hosts file must terminate with a new line.

Sysadmin somehow resolved this situation on his side. So now I use the -dns-server option to manually specify the addresses of DNS servers. And my testing api requests work.

emulator -avd nexuss5 -dns-server xxx.xx.x.x

According to the Emulator doc this is intended behavior:

Note that this usually means that the emulator ignores the content of your "hosts" file (/etc/hosts on Linux/OS X, %WINDOWS%/system32/HOSTS on Windows).

You, however, can access your host machine from inside the emulator with 10.0.2.2 (instead of testing in your example)
