Open GApps Helps Install Google Apps on Custom Android Firmware
Android: When you install a custom ROM on your phone , it probably doesn’t come with Google’s suite of apps. OpenGApps helps make it easy to get all the applications you need quickly.
The Open GApps project has been around for a while, but you had to download it directly from its site . The project now has its own app in the Play Store. Just install it on your phone and select “Install” from the pull-down menu.
The app will then guide you to select the desired google app package. It will determine which version of Android you are using, what architecture applications should be built for, and more. This makes it very easy to get the package you want every time.
