Unable to run the demos provided #276

Hello,

I recently downloaded this project and am trying to run the demo projects on my Samsung Galaxy s8, when I launch the app the usb camera is recognized but it fails to show the preview or crashes after I tap "Ok". Posted below is the error from log cat.

PS: I am using a Logitech C920 pro webcam.

Please help.

same issue with Logitech C930e. Configuring NDK 14 as recommended in #181 solved the problem for me
