Official Chromecast app adds Android screen mirroring

by: Andrew GrushJuly 9, 2014


At Google I/O 2014 we learned Google planned to introduce Android device screen mirroring to the Chromecast, a feature that exists in Android L but isn’t working in the developer preview just yet. The good news is that the wait is over, as the feature is now rolling out in a new update to the Chromecast app.

Up until now, the Chromecast app has been of little use outside of initial setup of the device, but the new update brings the “Cast Screen” option to the navigation drawer. For those with a Nexus device, the setting will reportedly make its way to the quick settings menu as well.

For those that don’t know, mirroring allows you to cast the content of your Android device’s screen over to Google’s media streamer, and should be compatible with any existing Android apps. At least for the moment, the beta casting feature only works with select Android 4.4.1+ devices including the Nexus 4, Nexus 5, Nexus 7 (2013), Nexus 10, Galaxy S4, GS5, and a few other popular devices from HTC, LG and Samsung.

The update to Chromecast 1.7 will rollout in stages, but we’ll be sure to update this page if/when we’re able to get our hands on an APK.

    Surprised there’s no Moto X support. Very surprised.

    • Andrew Grush

      They will supposedly be adding more devices in the near future, so it’s only a matter of time. That said, I’m also surprised it’s not one of the first on the list.

    Should custom ROMs with 4.4.1+ work, even if the device isn’t on the list?

    • Jayfeather787

      I am about to find out.

    • Jayfeather787

      Well, I could not get it to connect it to wifi. Maybe I will try later.

      • dogulas

        weird. yeah let us know.

      • dogulas

        If it is similar to the ability to make movies from the Google+ Photos app, Google has somehow made that completely dependent on specifically supported devices, rather than any custom ROM. I hope this is different.

    For those with Android L, it seems this works just fine now as long as you reboot… except the sound on my Nexus 5 is screwed up. Until the sound issue is fixed it makes screen mirroring semi-useless. I also tested with Sonic 2 and found that it worked pretty well (minus sound) MOST of the time — but lag does exist for gaming. Not surprisingly really. Still, all and all, this is a welcome feature that will likely get better in time.

      As of yesterday, the “Cast Screen” button on my Nexus 5 and Nexus 7 (2013) pull down notification menu have the exact same effect as Cast Screen from the Chromecast app. Screen casting from my Nexus 5 seems to work very well for a beta. My Chromecast app is still not updated to version 1.7. So apparently, you do not need an updated Chromecast app to cast your screen, if you have a Nexus 5 or 7.

    Wonder if this will work on my HTC Sensation with CM11 4.4.4.

    • j

  • roger e.

    my last link did not work for some: here’s one from media fire:

  • Stan Hertz

    Has a verified apk been posted yet? Is the one in this comment thread ok to use?

    • Suminati

      That one up there doesn’t work

  • John Zakaria

    And no Sony device…

    • Chris

      Sony sucks

      • John Zakaria

        Why do you think that?

  • Roy Chao

    Any word of a ChromeCast 2 on the horizon? I want to buy one now but its about to be 1 year old.

    • Shark Bait

      I don’t think so, would have been mentioned at io if there was. Tbh I don’t think there’s much point in them upgrading the hardware as its not meant for heavy lifting , and it streams html5 just fine.
      I think android TV is the new thing, Chromecast will remain the same for a while longer

  • Shark Bait

    Wow works amazing!!! Very well done google. Minimal lag, and good resolution. I’m typing this now by looking at my telly!

    Chrome casts new killer feature !

  • Jules Landry-Simard

    Am I the only one who have had the cast screen option in the quick setting menu for some time (at least days). Not sure if it work

  • Brandon Miranda
  • Scott Northcut

    Basically just the best thing about the feature… Just saying…

  • John Garlits

    Tried it last night with my Nexus 7 2013 (stock, 4.4.4), and it worked pretty well, though I noticed a lot of stutter at first. I suspected my wifi was the lag and got a wifi signal boosting app (Network Signal Speed Booster is the one I used, but others probably also work the same), and it was much improved. The N7 itself did start running hot though, and it was itself slower even on the N7 screen. I’m looking forward to trying it with my G2 which has more processing umph. Overall, there is still a slight delay, so timing-intensive games aren’t ideal. Simpler ones are no problem though, partly because you learn to anticipate the delay. I think a wired solution is still needed for real lag-free play. With my 1080p TV, it left a black border around the main image. I feel like the full resolution is not projected to the TV. I tried other TV settings besides just scan but these were mostly just over-zooming the image and killing the resolution. It’s still better to use chromecasting apps for video purposes because these use the whole screen, and buffering helps avoid any screen stutter if the Wifi signals fluctuate. Also, I noticed that especially with fast movement that the full resolution didn’t always keep up – perhaps a limitation of the N7’s power or my Wifi?

      Great review I also have a nexus 7 I am thinking of getting a chromecast to stream the news I live in Florida but want to stream the local news live from Pittsburgh.The station broadcasts on the web but when I tried to stream from the chrome tab the experience was horrible. I dont want to stream clips I want to stream the news live with out the audo and video getting out of sync. Have you tried this at all. No the station does not have a native chromecast app. Let me know at @kiddjudge

      • John Garlits

        It should work. Anything you see and hear on screen, like a site on your browser, will show on your tv. No issues with audio syncing that I noticed. Only thing is the quality depends on your Wi-Fi connection, but for a news broadcast that should work well enough. I say go for it. The Chromecast is not expensive. You could buy from some local store and return if it really didn’t work for you.
