Install google play on emulator How can I install google play on emulator? I start my emulator like this:

./emulator -avd my_custom_device_API_26 -dns-server 8.8.8.8 -writable-system 


and I tried it this way but it doesn't work. Although I'm staring emulator as writable, I get: 

remote couldn't create file: Read-only file system


Also I've bit different Apks as mentioned in that answer namely: PrebuiltGmsCorePix.apk instead GmsCore.apk and I can't find GoogleLoginService.apk. I have openGapps 8.1 pico version. I've also tired to install Apks but was unsucessful
For that you have to install Google play image from Android Studio SDK manager.But you can't get it for api level below 24
