Use OpenCV without any external installation Android

edit

Hi,

I'm using OpenCV on Android devices.

I have 2 kinds of problem using OpenCV libraries:

1. If I'm trying to download the OpenCV package by using the apk file, The user interrupted twice, first, he needs to go to settings and change the "Unknown sources" option and after it install the OpenCV.

2. If I'm using the option to let the user download the OpenCV Manager from google play, I'll take a risk that maybe a new version should not work with my app(already happened).

I'm using really few OpenCV functions.

I would like to know if there is a way to use OpenCV Manager/OpenCV specific libraries without any interrupt to external installation?
