Thanks to the joining with the Open GApps project, this package is now available for both arm and arm64 devices, from Android 4.4 KitKat to Android 5.1 Lollipop.
Download:
You can find the latest version from the website OpenGApps.org
You can download now any package and if a Stock ROM is detected, it will switch to the "for Stock" mode.
The issue I'm having is that any app not in the OpenGapps is being uninstalled. For example I really just need the files in the pico package but flasing it will remove all my Gapps and install only the apps in the pico package. Needless to say this behavior is undesirable as I only want to update the apps in the pico package not remove all the other Gapps. I'm able to move all other apps from the PlayStore to the system using Link2SD except Google Play Services and obviously there are some core apps in pico that are not updated through the PlayStore so I really only need the pico package but that doesn't work because of this undesired behavior. Is there a way around this?
