Hi,When I start the camara using camaraIndex different of 1 (Front Camara) on my Samsung Galaxy S4 the video crash it.

The test that I did: mCameraView = new NativeCameraView(this, 0); //fail

mCameraView = new NativeCameraView(this, 1); //successfull

mCameraView = new NativeCameraView(this, -1); //fail

Also I tested it with and Camera index different of 1:

OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3,this, mLoaderCallback); //fail

OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_8,this, mLoaderCallback); //fail

I am using OpenCV Manager version: 2.16

Device Information: Hardware ARM v7 with Neon and VFPv4 OS version: REL(4.3), API 18

Installed packages: Built-in OpenCV library(active) Library version: 2.4.8.0 rev 1 Target hardware: armv7a neon
