I've installed Gapps (Gapps CyanogenMod 13, Android 6.0 – Marshmallow (for Android 6.0 Gapps also) HDPI / MDPI / TINY: gapps-600-base-20151016-1-signed.zip) on my Android guest OS on VS Emulator for Android (using the 5.7" Marshmallow 6.0.0 XHDPI Phone API Level 23 device image) per https://stackoverflow.com/a/31564712/229011 (and got a success message in adb) and the only thing that is surfacing after restarting the emulator and guest OS is the Google Play Store. Launching it just opens a blank white screen which promptly closes.
I've even tried drag-and-drop install of the gapps zip and it says it is successful and prompts to shutdown (which the adb method didn't do), but there is still no change.
