How do I find the right GApps for my CM? I've chosen https://download.cyanogenmod.org/?ty...&amp;device=encore
(cm-11-20160815-NIGHTLY-encore.zip)

What GApps should I download?

PS: I've tried a random one (Gapps file), and it didn't work.
I think there's no need if you use chrome or Firefox as internet browser then OpenGapps will try to automatically determine your Android version.

If that fails then


Go to settings
About Phone
There will be - Android version or version


Select that on OpenGapps website and download the suitable package....

Hope it will be helpful....
