The Android Transporter allows you to share display content wirelessly with remote screens in real time. Now, the Android Transporter also runs on the Raspberry Pi which enables you to easily share the display content of your smartphone or tablet with a television set or a video projector. Just watch the amazing demo video.
The Android Transporter turns your smartphone or tablet together with the Raspberry Pi into a powerful media hub to watch movies, play games, or do slideshows.
This way, the Raspberry Pi becomes maybe the cheapest gaming console or set-top box

Is the Nexus 7 the only device this can run on?
No, the Android Transporter also runs on the Nexus S and on the Galaxy Nexus.
Any eta on the release? I just finished an in-car pi build and this is exactly the thing I need to integrate it perfectly! Thanks!

This is beautiful! I have a raspberry pi and a Samsung Galaxy S2. WIll I ever get to play with this on my phone?
Sorry, but I don’t think so.
Awesome! Just can’t wait to have it
Have you tested it on a Nexus 4?
No, currently the Android Transporter does not run on the Nexus 4. Maybe in future…
is it possible to stream from the nexus 4 to the transporter on the raspberry pi though ?
No, currently the Android Transporter does not run on the Nexus 4. Maybe in future…
Hello, this is great! I wish you had this released yesterday
Cant wait for it!!
We already released the Android Transporter for various devices. Take a look here: http://esrlabs.com/android-transporter-for-the-nexus-7-and-the-raspberry-pi/
Why does this require me to install a CFW, rather than an app(with root perms) or just a flashable patch.zip.
I really want to try this, but i also can’t be bothered to have to install and set up all my apps again.. also will this mean i loose OTA updates from google?
Yes you would loose OTA updates from Google. What you can do is to install the original firmware from Google after playing around with this. You can also install both firmwares in parallel and switch between them using ROMManager.
It is not an app but a whole custom ROM because we needed to change some Android platform interfaces. Maybe the native parts are still binary compatible with Android 4.1.1 but I am not really sure. (E.g. we added virtual functions to C++ classes which may have broken binary compatibility.)
Any update?
Yes the Android Transporter tech demo has already been released: http://esrlabs.com/android-transporter-for-the-nexus-7-and-the-raspberry-pi/
any news about release yet? Its thursday now and I bet loads of people are waitin for it
Wow… why is this not out yet is already the start of the week (sorry keep up the good work)!! cant wait.. was just wondering these work on rooted Samsung 4.0.x devices?
The first week of october ist almost over. I beta release today?
I am so excited about how it works.
The software is ready but the tech demo video is not. We will do the video today so we will definitely release the software package at the beginning of next week. Sorry for the additional delay.
I’ve been following this comment thread for a long time, I’m excited that this is so close to completion. I’ve got my Nexus 7 and Raspberry Pi primed and ready
Are we still looking at a launch sometime this week?
Any news for release? My Raspi get`s dusty
Some tegra 3 games are supporting stereoscopic 3d over HDMI. Would it be possible To enable this 3d slider when the nexus 7 is connected To the rapi
Sorry, I don’t think so.
I have a simple question. What will need to be done on the Nexus 7 to use this? Is it just an app? or is it a full custom rom?
I should have read the other comments first. I see that it is a custom rom. Hopefully CyanogenMod will incorporate it or AOKP because most roms are based off of them.
Any plans on porting the video over to the RCA so that it can make old TVs without hdmi usable.
It’s September! Any plan’s on releasing the beta?
Yes! Next week we will do some more internal tests and docs. Then we are able to release a first public beta. It will be in the first week of October. Sorry fo the delay, but getting the Android Transporter up and running on the Nexus 7 took us some more days than expected
.
Anyway it’s cool
) or Apple AirPlay (in iOS) 
It would be very comfortable when the transporter app is highly integrated in the android OS. Like Nexus Q (No, I don’t have one
Are you planning on making a client for other linux distributions? Like debian or ubuntu? Also, some video cards may not have the ability to hardware decode the video stream on the client side, any change of decoding using opengl?
I know someone previously asked for a windows client, but I thought a generic linux client wouldn’t be too much of a stretch. Regarding what I asked about, can’t opengl be used to assist in decoding a video stream where a hardware decoder isn’t present?
Oh, please have a 1:1 mode. I noticed on a lot of android tablets/phones, what you see via hdmi on the hdmi display is not what you see on the device itself. E.g. bottom menu hidden, video playing fullscreen on hdmi but not on device. I think the main motivation is for movie playback but having menu’s hidden made it useless to use with a mouse/keyboard.
But fantastic work! I need to get a couple of raspberry pi’s
We use VLC on Linux as client. It works quite well but the latency of VLC is not as good as that of a hardware accelerated media player. Let’s see how far we get on PCs with Ivy Bridge architectures.
Great idea. I’ve recently built my own NAS, where I store all my movies, music etc. Rasp PI is a bit slow for me to become fully functional HTPC, so I plan to buy Nexus 7 to play movies and stream them to my TV (not only to do that, but it’s a tempting idea). I can buy Nexus Q (299$) but Rasp PI and Android Transporter would be much cheaper
I wish you a lot of luck, guys!
Thats amazing!!
When will it be released for beta testing and open source development?
We plan to release the first beta in september. We will write about it
.
How can we get in on this beta testing?
We are currently working on the Nexus 7 to make it basically work. When this is done we will announce a beta test via Twitter.
Any update on the beta testing status? I have a Nexus 7 and a Rasp Pi (B version) with the Netgear wifi adapter ready to go.
The Raspberry Pi software is now ready and we are currently trying to tune the Nexus 7. I think in 2-3 weeks we are ready to release a first beta. Stay tuned…
Can every WIFI Stick be used? Or is a special one needed?
The WiFi stick has to be supported by the Raspberry Pi Linux kernel. So there are a lot of different sticks that should work.
Looks like a very usefull project.
Do you have any plans to integrate this as a plugin into the “Raspbmc” for the Pi? That would be the perfect mediacenter.
We plan to open source a version of the Android Transporter for the Raspberry Pi. So maybe the Raspbmc people like to integrate it
.
Hey, this looks awesome! Can we expect a public beta soon? I got a Nexus 7, and I’ll be getting my Raspberry Pi in the mail later this week. So, if you’d like an extra tester for Nexus 7 support, I’m game. I’m not afraid to modify my firmware or do whatever else you need me to do. Thanks for responding to all these comments by the way, you guys rock.
I hope we also get our Nexus 7 next week. Then we will be able to adjust the firmware and hopefully release a public beta.
Why don’t use mpeg2-ts? Should be lots cheaper performance wise, and Bandwidth still shouldn’t be an issue..
The transport protocol does not matter that much. The hard problem really is to minimize the video encoding and decoding process. Furthermore, according to the IP Streaming of MPEG-4: Native RTP vs MPEG-2 Transport Stream whitepaper there are some benefits from using RTP instead of MPEG-2 TS.
Looks useful. Any intention to let it run also with older Android phones (e.g. HTC Desire HD)?
Buying a £25 RaspPI and being forced to use a $500 Android device sounds a bit conflicting…
Sorry, but since we don’t have the time to support that much phones and Android versions, we currently stick with Android 4.x devices.
Seeing the video around 80 second, I can see a special icon like Wi-Fi connection (on the upper left side) as well as 3G connection (on the upper right side) of the desktop. Can the screen via 3G be mirrored to the display by Android Transformer?
In principal this would be possible, but currently we support only WiFi connections.
Are there plans for the client to be something other than a Pi or another android phone? Like streaming from android phone to a windows PC?
No, currently we do not have any plans to do so. But since this technology will be standardized by the Wi-Fi Alliance under the name Miracast I am pretty sure that there will be Windows clients.
I’d love to be able to browse my picture gallery & get if full HD on TV with the possibility to scroll & zoom easily to parts I ‘d like to highlight :;)
I had a similar idea where you can for example search for a video on youtube on your phone and then send it to Raspberry Pi to stream it on the TV rather then mirroring what you see on your phone. Basically you start any kind of action on your phone and then push it over to Raspberry Pi to continue processing it.
Amazing work you guys!!! i can’t wait test it on my HP touchpad to RasPi. Please please please….
Looks awesome! I can’t wait for the release. We have been looking for a good way to project an android phone to a big screen while cord free.
This is amazing. And I love that you are going to open source once stable. My question is, when using two android devices together, say projecting a phone screen to a tablet, are there any plans to allow the tablet to provide input to the phone?
Yes there are plans to do so. Currently we are working on streaming audio along with the video and on input events to control the master device from the client device.
excellent work and very interesting,
I’ll try it on my Galaxy S3 as soon as you release it
best regards,
I have a Nexus One and a Galaxy Tab 10.1 both running CM9 (Android 4.0.4) and I am expecting delivery of my raspberry pi in the next few days. Is their anyway I could achieve this set up using these device’s?
Sorry, no. We currently only support the Nexus S and the Galaxy Nexus. We also plan to add support for the Galaxy S3 and the Nexus 7 in the near future.
Why is that? If its connecting via bluetooth or wifi, shouldn’t the screen resolution be the only varying factor here?
The limiting factor for the Android Transporter is the speed of the hardware H.264 encoders and decoders. That is the major part of the latency. So it really depends on the hardware. The network bandwidth is not an issue.
Hi, it’s great idea
But how to obtain Pis software? Because ROM for Galaxy Nexus I get from second post about Transporter.
It’s hard to extend supported phones? How deep you changed rom? Because I didn’t see any new files and big changes.. maybe I loose something?
Currently we only supply a ROM for the Nexus S. We haven’t released the Galaxy Nexus ROM yet. Also the Raspberry Pi software is not yet released. But we are working on it and hopefully we can release the first public beta in 2-4 weeks.
At the moment we focus on the Nexus handsets with the Android Transporter. Therefor, we have done changes and extensions to the Android platform at various places.
It’s amazing really, but it’s only for Google nexus or every Android like HP Touchpad ?
Currently the Android Transporter runs on the Nexus S and on the Galaxy Nexus. But basically the Android Transporter runs any Android 4.x device that has a powerful and fast H.264 encoder/decoder.
We plan to extend the Android Transporter support to some other handsets such as the Nexus 7. Stay tuned!
Amazing work you guys. Hopefully you will be able to get this to a release point soon. Happy to offer my services as a Beta tester since I own a Galaxy Nexus and a Pi
Keep up the great work. I hope to be one of the first people to give this a whirl.
ESRLABS = genius idea
Looks great. Any way to get notification when it comes out? I really would like to test this out on my Galaxy Nexus / Raspberry Pi!
You can either follow us on Twitter or subscribe to our RSS feed.
We will keep you up to date on these channels.
Looks great! Would it be possible to stream like this from something other than a cell phone running Android? Would you be able to connect it to a device/computer running Windows 7?
Thanks!
Yes, of course. When you can grab, encode and send the frames of a PC fast enough it will also work there.
This looks great.
Would be possible to add this app as a plugin to XBMC, so you could be runing XBMC as your media player on your Pi, and just switch over to view Android Transporter content?
I think that should work, but I am not that familiar with XBMC.
.
Since we plan to release the Android Transporter for the Raspberry Pi as an open source project in the near future, the XBMC people can do so
Read my mind! had exact same thought – got my Pi in the post yesterday and am itching to install xbmc. Then i saw this. A match made in heaven!
I’ve planned to utilise the CEC channel through HDMI to control the R-Pi media with my TV remotem BUT, this seems a lot better!
Drawbacks for playing media directly from Pi storage or attached storage is the power drain, but if the content is stored and streamed from my Android phone i can play unlimited media through my Pi to the TV without that power drain.
I’m a programmer and Pi owner so if any assistance or testing is required sign me up as i have no free time for anything else but getting the Pi to send media to my TV in the best possible manner.
Greate stuff! Looking forward to it!
What operating system are you using on the Rasp Pi? What model USB Wifi dongle are you using? any problem getting it to work?
Thanks Much
Regards, Ron
We are currently using the Debian image from raspberrypi.org.
The WiFi USB dongle is a Netgear N150 Wireless USB Microadapter. You have to use the drivers from the Realtek homepage to make it work.
Daniel, sounds like a must-have! Will the android app require root access to the phone/tablet?
Reading stderr’s comment, I would also love to be a beta test if you need some real-world testing.
The Android Transporter requires a full firmware update since we have done adjustments to the whole Android platform. So root access will not work for the Android Transporter, but we are already in discussions with some well-known replacement firmware distributors and mobile development communities.
Would this work with a wired Ethernet connection to RPi, and the phone connected to the wireless router in the same network?
Yes, it does!
Sounds fantastic! One of the few programs I would like to buy more than 10€.
Let me know if need a beta tester. (RasPi, Tablet and 3 Android-Phones available
)
AirPlay, eat your heart out
How was this done? Mind sharing the application so others can try it out?
Thanks, Shawn
AWESOME!!!!! many thanks!!! hope to enjoy soon!!!
Looks fantastic so far guys! Keep up the great work, I hope this is ready for public consumption by the time the next batch of RP are sent out.
Worried the lag might be a bit too high for gaming.
Currently the latency is about 150ms. That is ok for car racing games and a lot of other games. But of course not for any kind of game. So we are still working to reduce the latency. Our current goal is to get below 100ms.
