Genymotion android模拟器adb shell无法编写/ etc / hosts

Question

I have some virtual hosts under my localhost and I need to add it to /etc/hosts in Genmotion android emulator.

for that I used in windows cmd:

adb shell
mount -o remount,rw /system
echo "192.168.xxx.xxx   my_virtualhost" > /etc/hosts

I have tried that to this virtual device: Google Galaxy Nexus - 4.2.2 - API 17 - 720x1280 and all ok. I got root shell and my_virtualhost is added to /etc/hosts

But when I tried to do same on other virtual device: Google Nexus 9 - 7.1.0 - API 25 - 1536x2048 Don't work and I got this:

adb shell
mount -o remount,rw /system
echo "192.168.xxx.xxx   my_virtualhost" > /etc/hosts > /etc/hostsvbox86p:/ # mount -o remount,rw /system
mount: '/dev/block/sda6'->'/system': Device or resource busy
1|vbox86p:/ # echo "192.168.xxx.xxx   my_virtualhost" > /etc/hosts

Any idea how to solve this or another way to edit /etc/host ?

Answer 1

I had the same problem on my OnePlus 5.

Had to upload modified hosts file to /sdcard and then copy it to /etc/hosts via Root Explorer app which handled rw remount properly on the fly.
