Android adb not allowing me to go into read-write mode

Question

I am trying to upload a hosts file to my android emulator, and I have followed and Google'd everywhere, but I cannot get my emulator to go into rw mode so I can upload my hosts file to it.

First I startup my Emulator so it shows up in the device list.

Next I log into the shell from the commandline:

$ adb.exe shell

Next I run the following command:

root@generic_x86:/ # mount -o rw,remount /system

I then get the following message:

mount: Read-only file system

Why can I not change the settings?

This is what I was following: https://end0tknr.wordpress.com/2015/07/19/edit-hosts-file-via-android-device-monitor-in-android-studio-and-adb-shell/

Answer 1

try changing the settings by opening the emulator from command prompt in writable system mode

sdkpath/emulator -avd -writable-system

and then follow root, remount,shell....
