I tried getusermedia on mobile browser and it works fine, however when putting it in webview I always get permission denied error on all 3 of my android devices I'm pretty sure the app has successfully granted camera access

const constraints = { audio: false, video: { facingMode: "user" } }
 navigator.mediaDevices.getUserMedia(constraints)
 .then(function(mediaStream) {
 video.srcObject = mediaStream;
 video.onloadedmetadata = function(e) {
           video.play();
  };
 })
 .catch(function(err) { showAlert(err.name + ": " + err.message); });

issue link in ionic

Can anyone point out what I am missing?
