I'm getting the following error when running any of the sample codes. My device details is a Motorola Moto X 2nd gen (2014) running Android 5.1 stock.

It is in all probability failing because of this call in class CameraGestureSensor (package edu.washington.cs.touchfreelibrary.sensors;): params.set("iso", "400");

Some front facing cameras only support "iso" to be set to "auto": params.set("iso", "auto");

Some device cameras expect for eg: params.set("iso-speed", "auto");

You will have to change the code in the class and see what works for your device. See this posting: http://stackoverflow.com/questions/2978095/android-camera-api-iso-setting
