Android Enthusiasts Stack Exchange is a question and answer site for enthusiasts and power users of the Android operating system. It's 100% free, no registration required.

I am looking for a solution/technology which allows remote screencast display and control from desktop. My goal is to provided remote mobile device display through a browser. I found some existing solutions:

  • AndroidScreenCast: Based on ADB interface. this is just screenshots using a simple primitive provided by ADB. low display.
  • VNC client & server. works for both rooted android and jailbroken iphone. low display.
  • iDemo + ScreenSplitR: Better, jailbroken iphone only.
  • HDMI/TV output: No remote control.

I've heard about "direct-to-device" technology which is used by DeviceAnyWhere. Are there any other solutions?

Webkey is my personal favorite remote control program. It turns your phone into a web server, complete with https and username/passwords with permissions you can set. So you could have an admin user with full access, and a standard user who can just see the screen.

On top of built-in VNC, Webkey also gives you the ability to track your phone by GPS, connect to a terminal, browse and download files from your device, and a bunch more administrative things. Though this sounds like it is outside of your needs (but you don't have to use those features).

And to top it all off, Webkey is open source and free, encompassing every Android users' favorite two buzzwords.

Note that root is required for this. Likely any solutions will require root; there may exist an android app that accepts commands from some server and initiates the proper INTENT to open an app. Even then, sharing and controlling the Android screen will require root. –  Stephen Schrauger Dec 7 '12 at 17:44
    
Webkey is one of the best ones for frame rate refresh. But it does require root I use this for demoing all the time. –  JPM May 7 '13 at 19:39
    
@StephenSchrauger Do you have a reference for the "controlling screen requires root" assertion? –  cja Jun 19 at 16:31

Thanks for the hint to "open source". Webkey requires almost all permissions it could find (more than 125!), which looks terrifying otherwise. From the almost 10.000 apps in my Android app listings, the next one in terms of perms is an "anti-virus" app requiring 51… –  Izzy Jul 3 at 10:48
    
@Izzy Since the app requires root access, in theory the rest of the permissions are moot. Although using the standard permission model/api is probably easier to code than writing everything yourself. –  Stephen Schrauger Jul 10 at 12:25

Try a free app called AirDroid, which lets you control wirelessly your Android device from a desktop browser.

This is a fragment of Play Store app description:

Realtime Android screen (experimental feature, root permission required)

View your Android's screen, take a screenshot, or even record a screencast.

Airdroid

Here's a video showing some of its features.

Could you please explain how to direct a ScreenCast using this app, as the questioner asked for? I must have missed that with AirDroid, as I never noticed it had that functionality. –  Izzy Dec 7 '12 at 16:08
    
@Francisco : thanks for this nice app. But this is not what I want. I would like to take control over the device and launch apps from the browser or a desktop app.. –  cyrius Dec 7 '12 at 16:24
    
In fact, I focused my search in remote control from desktop rather than screencast, given that I had seen recently AirDroid app among the Play Store recommended apps. I read in the app features that it lets you to do a real time screen capture (experimental, needs root privileges), i.e. a screencast AFAIK, but I don't know if it fits what the questioner needs (privileges part). –  Francisco Alvarado Dec 7 '12 at 16:24
    
I just checked the app's playstore description: in fact it has an experimental feature which might come close to that, but it requires root: Realtime Android screen (experimental feature, root permission required) View your Android's screen, take a screenshot, or even record a screencast. Maybe you want to include this information with your answer, to make it more valuable. –  Izzy Dec 7 '12 at 16:29
    
Thank you, @Izzy, I'll do. –  Francisco Alvarado Dec 7 '12 at 16:32

All existing non-root-required product works at a very slow frame rate: 0.8 frames/second for a typical screen size of 720x1024, so they are not suitable for realtime display purpose.

"sji android screen capture" will fit your needs, No root required. Just with PC's Browser. Works at frame rate of 4+ for fullscreen of 1080x1920, 8+ fps for 320xauto down-scaled size. At the same time, it can record to mp4/webm, and can remote control android from PC's Browser.

Good luck.
