Android. Plugin does not work

[sgrebnov]

Polyfill is installed, pointer events are fired, but multi-touch does not work and test/tracker sample page reports my touches as mouse instead of touch, to be investigated.. (no such issue if I open same page in android vanilla browser)

Investigation results

Touche listeners are not installed because Polymer relies on the DOMContentLoaded event which should be fired https://github.com/Polymer/PointerEvents/blob/stable/src/installer.js#L81

installOnLoad: function() {
      document.addEventListener('DOMContentLoaded', this.installNewSubtree.bind(this, document));
}

When Polymer is being installed via plugin document.readyState === "interactive" and no 'DOMContentLoaded' event is fired after that.

There is some related discussion here http://mail-archives.apache.org/mod_mbox/incubator-callback-commits/201206.mbox/%3C20120601235227.4EAE5F656@tyr.zones.apache.org%3E

DOMContentLoaded is fired before Polymer code is run

The following workaround can be used. We need to contribute it to Polymer

if (document.readyState === "interactive" || document.readyState === "complete") {
    this.installNewSubtree(document);
  } else {
    document.addEventListener('DOMContentLoaded', this.installNewSubtree.bind(this, document));
}
