Alguém sabe como posso vincular o telefone a um PC? Para uma TV?
How can I project my Droid Incredible screen so I can demonstrate the smart phone to a room full of people?
Does anyone know how I can link the phone to a PC? To a TV?
You can use this project to connect to control and see your phone from your desktop computer:
All you need is
the Android SDK installed and an app OS-bundle (use one from the latest release) and a phone that you can use in debug mode over the USB port. Next you can run the screencast right from your browser if you have the java plugin, just open the jnlp link: androidscreencast.jnlp. You can also download it and run in a terminal with
For Android 5.0+ there is scrcpy is an open-source screen mirroring solution.
Download pre-built binaries at above link.
screenrecord is an internal Android executable that dumps screen to a file, and
ffplay from ffmpeg happens to be able to play an H.264 encoded stream from stdin
First enable ADB USB access.
Then, put your Android screen in landscape mode to fill the entire desktop display (not like in the portrait demo below), and then on Ubuntu:
sudo apt-get install adb ffmpeg adb exec-out screenrecord --output-format=h264 - | ffplay -fs -framerate 60 -probesize 32 -sync video -
You might have to make the screen move a bit before you see anything:

adb shellbecause shell might mess up some control characters due to being a shell (thanks to @Bowi)

Tested on Ubuntu 20.04, Android 11, Pixel 3a.
Per the idea of using a TV (or projector) specifically, many devices can do this pretty easily using some kind of digital audio/video output connector. Some devices have micro or mini HDMI ports, which could be used with a proper cable to connect to any HDMI receiver. Others support the MHL standard, which does the same thing but via the USB/charging port. Still others (notably Samsung's tablet lineup) use a proprietary dock connector, but have appropriate composite or digital output cables available.
Typically, support for any of these will be noted in the device's specs, so if outputting content to a TV/projector is an important feature then you'll want to simply examine the spec sheet for such information. For the HTC Incredible specifically, you can get a micro-USB to composite cable.
I use the Mobizen app to share my android mobile screen on a computer screen. The new web browser version is convenient for presentations because it lets you stream any multimedia from your phone.
You can simply:
I tried AndroidScreencast and Droid@Screen but they were very laggy.
I had success with https://www.vysor.io/, in free version it's ad supported (once every half an hour) and is limited to the lowest quality (which occasionally produces artifacts). But overall it let me do a presentation without any issues.
I just downloaded the Chrome extension and it took care of everything, the setup was quick and easy (even though I'm on Ubuntu).
You can e.g. do so via open-source app ScreenStream (available on Google Play or F-Droid) if you want to access it via a network (wifi).
adb can thankfully forward network sockets. So:
adb forward tcp:8080 tcp:8080(syntax:
adb forward tcp:LOCAL tcp:DEVICE) or another port you have set in the settings to forward the connection.
adb forward --remove-all to remove that again.
Alternatively you can e.g. use adb alone on KitKat or higher as it has a built-in screenrecord feature, but you need a player on your device then. (no simple web access possible.)
Maybe you can use the TeamViewer tool. You have to install the Android part (https://play.google.com/store/apps/details?id=com.teamviewer.teamviewer.market.mobile) and the desktop/laptop part (http://www.teamviewer.com). Then your computer has to be connected to a video projector or something like that.
TeamViewer is free for non-office use and pretty smart.
You can use Bigscreen Broadcast ($0.99 on Google Play). It doesn't require any rooting, and you can install it right from the Google Play store. It enables you to project your Android screen (any app) and your Android cameras (both front and back) to a ChromeCast, or to a free Mac companion viewer.
For full disclosure xe2x80x94 my brother built this after the functionality was released in Android and I figured I'd help him find people who were looking for this functionality!
