Use Proximity Sensors to turn on / off screen when receiving call

[naufanituharish]

Hi @YuliaGrigorieva, currently we are developing voip app using voximplant,.
and we are looking for the way how to turn on/off screen when receiving call,..
just like when the phone close to ear then the screen goes off and if away from the ear the screen goes on,.

could you give us some reference or library,.

regards,
