Wirelessly Mirror Android on Projector?

Does anyone know if it's possible to basically "stream" the screen to a projector? I'm thinking of an app that would have a server running on the desktop PC, where the Nook would wirelessly connect to that PC and display the screen of the Android on the projector.
Does anyone know if this is possible, or if there is an "app for that"?

i dont think the nook is suited for that kind of activity, you would need something like the droidx, which has a mini-hdmi output, then you can get an app to mirror the screen.
im not really sure of the benefit of streaming an android screen to a projector when the whole computer is there available to you? if its an issue of video content, there are a lot of other solutions that would work, if nothing else, a usb cable to mount the nook and access the video files through a desktop application

I think there are vnc servers for Android phones. If you need this for any video, it'll probably suck.

The main use case is for during a presentation, to be able to see the slides as they are shown on the projector, and potentially see the notes and such. It would be a super bonus to be able to make notations/drawings, etc., during the powerpoint if that's possible.

a more hardcore solution
not sure if this would help, but I came across a similar problem where I was doing a presentation so I wrote an air app for my galaxy tab, and one for a mac running a projector and used the netconnection and netgroup classes to send position and navigation data from one to the other. Have a look at the RTMFP protocol

App to use Xoom as USB keyboard?

There seem to be a few decent options for android phones to be used as keyboards/touch pads for a computer but they're mostly wifi or bluetooth based and simply aren't optimized for tablets.
I'd like to see something with an option for USB connectivity as well, but I'd be happy to find an app that is a bit more optimal for a tablet or at least looks decent on one. If anyone knows of something worth looking at, I'd appreciate the help!

i like this idea, it sounds very neat. What about using a android tablet like a wacom tablet? You know for art programs and such.

Capacitive touch panels aren't precise enough to match the needed level of preciseness from what I've seen. Besides HTC's Flyer.

I use Gmote. The initial screen you are taken to displays in portrait only and it controls media functions like play, pause and rewind. If you hit the menu key there is an option for touchpad. Touchpad uses all of the tablets screen as a mouse touchpad and there is an option to pull up the keyboard. This screen will work in landscape mode and works really well on my HTPC.
BTW the app is free in the market and will require you to install a free application on the computer. Works with Windows/Mac/Linux.
Donate if you like the app.

Controlling Android on a Raspberry Pi

I realize this is a dumb question but I haven't been able to find the answer. If I install Android on a Raspberry Pi attached to my TV, how do I control it? Is there a way to use a regular remote control?

There is always the wireless Keyboard and Mouse option.
I believe you can also use multi-touch touchpads such as Wacom Bamboo.

Thanks for the reply.I was hoping to use a media center remote or something similar, but I assume none of the drivers will work.

If you want to control your RPi using a remote I wouldn't install Android (The current builds aren't that stable and are buggy at best). I would recommend taking a look at Raspbmc, it's Xbmc for the RPi and should be compatible with a variety of media remote controls.

You can Use a Normal Mouse (And Keyboard)

Xbmc isn't really what I'm looking for. If a keyboard and mouse work, maybe someone will figure out how to use a remote.

When android is more polished I think you will have options

What are you looking for then? Since you want to drive it using an IR remote (I'm guessing), that typically indicates some sort of media center.

I run Windows Media Center on all my tv's with the Ceton Companion app to control it. Currently the app does not support streaming live tv but it is supposed to be in the works. When it finally supports streaming to android, I could build a small raspberry pi box and use it as an extender when I'm out of town. If nothing else I would finally have an excuse to buy one.

this is something like what I want, too. I would ultimately like to have an HTPC running android that supports video streaming, local media playback, live tv and streaming of everything above to all my connected devices.....like xbmc, but also with an option to use it as an android device when necessary. I don't want to have to use a mouse and keyboard for it either since my tv is too far away from the couch for that to be a reasonable option.....but mouse and kb support are still necessary for some things. IMHO, the best possible option would be a logitech remote that also has an on-screen pointer and motion controls like a wii remote has.
......come to think of it, an app supporting a wii remote to control android functions wouldn't exactly be a bad solution!!

you can use raspbmc instead of android if you are willing to use it as media center. it also has broader possibilities for choosing a remote.
http://www.raspbmc.com/wiki/user/configuring-remotes/
but i prefer this one most
https://play.google.com/store/apps/details?id=org.xbmc.android.remote
enjoy !

I use a regular remote from my tv when i use raspmbc since it supports cec. The xbmc remote most people use through their Android device is specific for xbmc, so it wouldnt do much good with anything else. Droidmote isnt the prettiest but its functions well. Theres a lot of apps for remotes, that even take advantage of voice and nfc. So when Android is running stable enough, you will be able to take your pic. If your not interested in embedded hardware or other similar usages for the pi, you could always get a g box midnight or minix neo g4 or 5. There all dual core and come rooted with firmware updates that will give you JB and xbmc. There is a quad core one that is out or coming out and will come with JB and full hardware acceleration.

Yatse is a damn good remote for xbmc, it syncs your library list to your device, so you can scroll on device, links to imdb for movies,you can change audio tracks,dl subtitles, and all sorts of cool stuff. And it's free
Sent from my DROID3 using xda premium

You can already stream to your ras pi from windows or wherever, I like prefer my tablet or phone. Download the app bubbleupnp from the playstore and it will populate a library of videos, music whatever you have on the device by selecting it as the local renderer and it will see the raspi then press play. Also some android apps like youtube for ex.you can just share it to the app and it will play on your tv connected to the pi. If I want a remote I use the official xmbc remote or if im using a win box to get the media ill use unified remote app. Which then gets cool cause you can use voice and all kinds of stuff.

Chromecast & Ultramon for dual monitor?

Will it be possible at some point to use Chromecast as a gateway to use the TV as second independent monitor, rather than a mirror of the laptop/desktop with a browser extension, maybe in conjunction with Ultramon?
I have Ultramon installed in my laptop. When I turn my iPad into a second monitor using an app like AirDisply, Ultramon immediately picks it up as the second monitor and provides all the functionality for a second monitor - position, resolution, task bar, etc.
Can I achieve something similar with Chromecast + Ultramon, if not now in the future?

No the CCast wouldn't do that since it would be a waste since the CCast connects to the same network the Android device does so why send it to CCast when you could send it to the Device directly.
CCast does however act as a second monitor for Android and other devices...

Future, maybe, but the 1-2 second lag from having to compress the video (and Chromecast having to decompress it at the other end) would be annoying at best.

Oh... I never noticed any annoying lag when I use iPad with AirDisplay. I guess iPad has lot more processing power than Chromecast.

AirPlay is designed for screen mirroring and hence low latency. The current methods of Chromecast desktop mirroring essentially make the desktop a video stream first.
Likely this will change once they're screen mirroring is implemented by devices.

I'm telling you. With AirPlay, there is more than mirroring. You can use the iPad as a second monitor. It works perfectly with Ultramon.

Yes, and screen mirroring/output isn't the core intent of Chromecast, and I'm not sure screen mirroring will ever make it to iOS for Chromecast.
Long story short, we all can want Chromecast to be more than it is and it's growing steadily, but there will be limits based on its core design.

Thinking about it more... I think Google could (and probably is) making the screen mirroring similar to how RemoteX works in Windows - instead of sending a picture of a red box, send a command to draw a red box - much less data and identical result as long as both source and Chromecast share the same drawing language and techniques. Definitely possible for Android-Chromecast, not sure if/how it could be implemented outside of code that Google owns though, including Windows as a source.
Apple has a definite advantage there as they can make sure iOS, AppleTV and MacOS all share a common drawing implementation.

Problem is, can't use computer when full screen for other tasks
You cannot use the computer screen for anything else when using Chromecast. thios would be a win win

Is it Possible to Run Android 5.0 / Android TV on Raspberry Pi 2?

Hello i'm kind of new to this so please don't be to harsh .
To run Android TV, android 5.0 would need to be ported first thus me titling this "Is it Possible to Android 5.0 / Android TV on Raspberry Pi 2?" However my main subject / me making this post is to see if Android TV on Pi 2 is feasible.
I was thinking would be possible to run Android TV on the new Raspberry Pi? I ask this because the specs of the new Pi 2 are quite impressive and I can totally see this becoming popular as I can imagine a lot of people would go out and buy a Pi just to run android tv on it (me being one of them) . This would be great as not only would it provide a large install base for Android TV (which in turn up the developer support) it would make it so almost anyone can have a cheap chrome cast type of device with a functional GUI. I don't know if this is possible but doing some research I can't see any reason why it would't work and it would make for such a cool and inexpensive android tv box! :good:
Possible short comings would be:
Lag due to low clock speed
Lack of a remote (possible use of a bluetooth controller or a smart phone app to control the box using wifi)
Poor Gaming capabilities?
Probably a few more.

My research indicates this would be difficult, however, if a Chromecast type Media Center is what you're looking fo, I have good news. There are 2 OS downloads that are essentially XBMC ports for Pi 2.
http://www.raspberrypi.org/downloads/
I bought a Pi 2 today and am waiting for them to provide a delivery date. I intend to use it with one of these XBMC OS'S.

Probably the same conclusion as this:http://forum.xda-developers.com/hardware-hacking/raspberry-pi/rd-android-4-4-4-t2816952

XBMC for RPi already supports CEC through the HDMI... So most of your remote problems are solved there. A wireless Bluetooth keyboard/touchpad also solves the problem.

Yes, I can confirm that, I'm using osmc(aka raspbmc) for more that one and a half years and the performance is a quite good, even if I have allot of other things running on my pi...
CEC is supported, but be careful if you own a LG webos tv you should not us this, cause will slow down your tv and make it unresponsive, as far as I know only webos TVs are afected(2014 models).
But anyhow if raspbmc has a good performance on the old rpi B, I think should perform way faster on the new pi2.
I'm planning also to upgrade my pi..

From what is being reported on the Kodi forums, the Pi2 does very well with it. There is already a branch of OpenElec for it, and I think also one for RaspBMC/OSMC with a lot of the add-ons under recompilation during this week to give full support. But it's certainly getting full support from the dev community there, which is great.
But as noted even the Pi1 does very well anyway with Kodi, my overclocked B+ with OpenElec 5.0.1 works fine with it and no issues at all that I encounter day to day. Nice and smooth, and fully supports CEC from my (dumb) LG HDTV. And if you prefer, there's decent remote control for Android/iOS (Yatse) and web-based remote built into Kodi itself.
I'd certainly recommend it as an excellent alternative to AndroidTV.

The Android porting issue is the lack of graphics chip support

I'm wanting to see this as well, namely because Android TV also offers direct support for Netflix, Hulu, Plex, and others. While you can potentially get these with an xbmc based build, it will not work well with remotes.

The Pi supports CEC, so if you've got a suitable TV and the two are connected by HDMI then you're fine to go. I run my OpenElec set-up on my Pi1 using the remote of my LG dumb TV, and it's a doddle. It does have a wireless keyboard and mouse connected to it for it's other life as a Raspbian programming box for the kids (Scratch/Minecraft/Python) but I don't recall the last time I took up either when it was running in its OpenElec identity...
There is certainly an implementation of Plex for OpenElec. Not sure about the others, as I don't use any of them.

That isn't the problem. The remote itself works ok, and the device can see the events. The problem is the individual applications require different key bindings. I've done all of that crap where you configure different profiles and whatnot to bind different remote presses depending on the app, but it breaks all the time and maintaining it sucks balls.
Not doing that again. It's better just to have one cohesive interface that each app responds to identically. Android TV provides exactly that.

Two years ago, tried a hand at Android 2.3 on the Raspberry Pi after seeing an article on Cnet.
:silly:
Utterly terrible failure. They have then proceeded to pulled the article down.

YES, it's possible, GUI at 10-15fps with SW rendering. Slow but useable.

Actually, the problem is not that(the stack was adapted to GNU/Linux, see github.com/simonjhall/challenge but with memcpys), it is just that it depends on a Linux 3.0 kernel driver for full functionnality(HW layers). That driver is still not ported to modern kernels(the official RPi kernel is 3.19!)
It is fully doable. On IRC with the primary developer of Replicant, he said that porting Mesa/VC4 with adding Android support would take a few time with mostly buildsystem changes .(he ported llvmpipe)

I would like to use Android version 4.2.2 Jellybean! on my RP2+, Please understand i don't really quite understand everything you guys are saying, I just would like a straight answer, can it be done? My pi is version 2+ 512MB ram not the four core version.

No. Check back in 6 months, maybe someone will have Lollipop running on it by then!

Android TV on Raspberry Pi 2... That's a dream...

Well, I have a question...
Got the Raspberry Pi 2 with 512MB of ram, and I've tested the beta Android found here, and it's usable (just usable, it has lag, and many things can be done to it to became perfect). Why doesn't anyone try to port that Android on Raspberry Pi 2? Now we have a 900Mhz Quad Core CPU and double the ram...

Could you please provide mode details?
What' the issue with the Wi-Fi?
How is the general performance of the Lollipop?
Do you have Play Store installed?
