[Nexus 7 (2013) Android Development] followmsi:
Chapter Google Apps ..

If you install the google version from playstore you still keep the AOSP version of the same app.

For example contacts .. calendar .. etc.

Made a small ".gapps-config" file :)

If you copy the file into the same folder where your gapps update.zip installer is located you can replace the AOSP apps by google apps.

As system apps - including pixel launcher which is working even better as system-app.

Pls modify the config file like YOU want .. add or remove packages like you want.

The installer will complain if you want too much :)

Pls find all the relevant information here:

Installation:

1. Boot into TWRP (latest version)

2. Copy ".gapps-config" into the same folder where your Gapps installer is located.

3. Start the Gapps installer -> open_gapps-arm-7.1-stock-20170330.zip (yes, we need at least stock version here !)

4. Reboot into system (no need for SuperSU - we have changed /system only)

Pls make a backup of "data" first - to be safe ! :)

Have been thinking of fixed gapps integration into this ASOP build .. for several reasons I will not do it.

Cheers
