My React native app is not running on a physical device.it's showing some Gradle error.
I check many articles but cant finds any soulation.
please help on out from this error.
You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.
Open the command prompt and type ipconfig to find your machine's IP address (more info).
Make sure your laptop and your phone are on the same Wi-Fi network.
Open your React Native app on your device
You'll see a red screen with an error. This is OK. The following steps will fix that.
Open the in-app Developer menu.
Go to Dev Settings → Debug server host & port for device.
Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
Go back to the Developer menu and select Reload JS.

I am doing a mobile test recording with jmeter, after i configure my mobile proxy settings to system ip and port to math jmeter. Internet stops working? P.S. i already installed the ApacheJmeterTemporaryRootCA.crt
There is a number of "mobile" operating systems and we are not telepathic enough to figure out which one you're talking about in order to provide troubleshooting instructions. I assume you use Android as it is about 75% of market.
Make sure to start JMeter's HTTP(S) Test Script Recorder prior to amending mobile device proxy settings
Make sure JMeter and mobile device are on the same subnet (connected to the same WiFi network)
Make sure that port 8888 is open in your operating system firewall
On certain Android versions you cannot set system proxy for HTTPS traffic, you will need to install a separate application like ProxyDroid for this
If nothing helps you can always consider an alternative way of recording mobile traffic, in this case you won't have to worry about proxies and certificates and you will get confidence that your device is connected to the Internet. See Testing Mobile sites and Apps article for more details.
I am very late here, but still this may help others who are still facing this issue.
In beginning i faced the same issue. Then, I tried by disabling the firewall. It worked fine.
Also disabling firewall may create a way for malicious contents to enter. Try only for trusted sources.
I have just downloaded and installed latest Rocket.chat using SNAP tool on Ubuntu (16.04 LTS). Overall, I had a smooth experience of installing and getting started with Rocket.chat. However, I did find a few serious issues.
I try to get auto SSL running by following the instructions at: https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/autossl/. But after configuring the Caddy file, the Caddy service failed to start, with the message:
Activating privacy features… 2018/04/24 17:58:09 open /root/snap/rocketchat-server/1254/.caddy/acme/acme-v02.api.letsencrypt.org/sites//.crt: no such file or directory
The second issue is with start video chat using webRTC. When I clicked on it, nothing happened. I am using Chrome browser and tried to start video chat on several devices. All the Chrome browsers have passed the webRTC tests. I don’t know why video screen is not shown.
I signed in with open.rocket.chat and compared the differences between my installation and the official site. When my browser points to open.rocket.chat site, the videochat does not work either. It does show the video window, but only displays only myself, not the remote member. Note to experiment, I signed up with 2 accounts to simulate 2 members chatting.
Also I downloaded the Android Rocketchat client. However, I couldn’t find the start video chat option. Is it true that video chat is unavailable yet on the Android client?
To summarise, we have the issue of setting up auto SSL with Caddy, and using video chat (webRTC). It could be that I missed a few basic configurations on my environment. Other functions like text messaging works fine.
We are deciding whether we should use Slack/CometChat for our instant messaging solution. It seems RocketChat has all the features we want, but it is a pity we couldn’t get it to work completely.
Appreciate someone can guide me in this.
I did some investigations on these issues, and have made some progress. I'd like to share my findings, which I hope could be of some help in future to newbies of RocketChat like me.
However, I still have a few issues unresolved, and hope someone could help.
Caddy service failed to start
Using self-signed certificate and defining the domain name in /etc/hosts, I can get Caddy service to start and https to work. My guess is that the domain name I used, even it is registered with a DNS provider, has no CNAME record, and is not mapped to any IP address. Letsencrypt, which is used by Caddy to do on-demand SSL, therefore is unable to create a SSL certificate for my domain name. It would be nice if the RocketChat documentation could make it clearer.
open.rocket.chat WebRTC-based video chat not working
after I used another Windows machine, the video chat is working. Presumably my previous computer does not have the latest Windows update. But I am glad with open.rocket.chat site, every feature I tested is working.
On my self-hosted Rocket-chat (i.e. a Linux server at home), however, the video chat is still not working. When I clicked on the "start video chat" button, no video screen is launched on my browser window. On the remote browser (which was used for simulating the conversation partner), there is a notification "xxx invites you to video chat, do you accept?". I clicked on "Yes". After that, nothing happens on the remote browser. The only issue I can think of is that I didn't use https to connect to the self-hosted Rocket-chat. Because I am using several computers in my home wireless network. I only use http://192.168.0.3:3000 to point to the chat server. I am wondering if secure connection is required in order to use video chat?
On the Android Rocket Chat app, I couldn't find any links to start a video chat, nor can I receive any video chat invite. Is it by design or a defect?
Hope someone can enlighten me on these issues.
I made further investigation as to why webRTC does not work on my self-hosted Rocket-chat instance. It is related to secured connection. There is a related discussion in the RocketChat forum:
https://github.com/RocketChat/Rocket.Chat/issues/1813
Basically, the connection to the Rocket.chat server must be secure for WebRtc to work. After I configure Caddy to support HTTPS listening on Rocket.Chat (currently using self-signed certificate), WebRTC works. It would really help users if the documentation can make this clear.
Now the remaining issue for me is to figure out if Android Rocket Chat app supports Web RTC.
I am building a web-based project which has webcam one-way broadcasting part .(A user can open its own cam and some viewers can join its room to only view and listen).
So i have decided to use Kurento Media Server(KMS) because of not having any experince with flash.
My questions in my head:
Do i need anything extra beside KMS to make a user broadcast webcam?
Can Kurento provide me the live streaming to webpage?
And What is the difference using Red5 or Kurento?
Thanks in advance
Do i need anything extra beside KMS to make a user broadcast webcam?
You'll probably need a TURN server for users that have some port limitations
Can Kurento provide me the live streaming to webpage?
Sure! Check the tutorials and the documentation for a full list of features.
And What is the difference using Red5 or Kurento?
Kurento is more than just a media server. It is a pluggable platform that offers computer vision and augmented reality capabilities, on top of video and audio streaming, recording and playing. It also offers WebRTC out of the box, which is something Red5 can't do as of today.

I have one website say social network hosted on BlueHost. THen i need a RTMP hosting server to enable live video chat. Bluehost doesn't provide it. Is it possible i can host the video chat part on another service that runs RTMP and connect the two sites?
Yes, you can freely embed information from another server to your main site.
Depending on implementation, you probably have to host the Flash stream player on the same server that is hosting the RTMP. This is because the same origin policy controls what servers the Flash applet can connect to.
The easiest solution may be to use an iframe to embed the video chat.
