Hi, I found a solution here : Android: URL.createObjectURL does not work properly
let url = (window.URL || window.webkitURL || window || {}).createObjectURL(blob);
// workaround for mobile playback, where it didn't work on chrome/android.
// fetch blob at url using xhr, and use url generated from that blob.
// see issue: https://code.google.com/p/chromium/issues/detail?id=227476
// thanks, gbrlg
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'blob';
xhr.onreadystatechange = function() {
if (xhr.readyState === 4 && xhr.status == 200) {
var url = (window.URL || window.webkitURL || window || {}).createObjectURL(xhr.response);
// now url is ready
}
};
xhr.send();
