We have a setup with a local IP camera connected over Wifi. From this camera the video stream should be streamed with an Android device over the cellular data network.
In iOS there is a trick to have both networks available by assigning a static IP address to the camera Wifi (iOS: Use WiFi and Mobile Data simultaneously). Is there something similar on Android? I have tried to set a static IP address and also the Android "Download booster" mode, but both without success.

I have a webserver that is running on a network that is not connected to the internet.
The webserver serves up a website.
When I connect an android phone to it, I am able to run the website that is on the webserver
But with certain phones that are running Android 11 I need to disable the mobile data on the phone before it will try to access the website over wifi. It seems the phone will not try to request the url on the wifi network because it doesn't have internet, so it defaults to using the 4G/5G Cellular internet connection. This is too bad, because I would like the phone to use the wifi connection.
I would think that perhaops I could "force" the phone to use the wifi connection by typing the IP address in the browser's URL bar (eg. http://192.168.211.1/index.php), however it seems that even with the "local ip" it will still try to use the 4G/5G network instead of the "offline wifi" network.
The only workaround I have found is to disable moblie data on the phone, but this is not ideal.
I would think that some IoT devices would have an offline webserver used for configuation/control.
Is there a certain port or settings I should be using?
Is there a designated port that the browser/OS would expect to be on an offline network?
Basically, how can I make the phone use the wifi, even though the wifi is not connected to the internet?
Thanks so much for any pointers!
My ip camera is D-Link dcs 932L. I'm using android application provided by D-Link to connect to ip camera with ethernet cable or using wi-fi with making some settings. But my problem is direct connecting without router. In addition the dlink light app doesn't allow wireless settings.
I am developing an android app to stream movies from local server on a WiFi. The WiFi does not have internet, it will be used only for accessing the streaming server.
What would make the app kickass is that the app users can continue using internet on their 3G while connected to my WiFi and streaming the movie.
I know for a fact that when android connects to a WIFI, the phone under the hood makes a call to clients.google.com/generate_204 to check if internet is available on the WIFI. If it receives no response, it continues using 3G along with being connected to the WiFi. However, in this scenario if my app makes a request to say 192.168.24.5 (ip address of my streaming server), it does not use WiFi to reach this ip but hunts for this address on 3G and fails.
What i need to achieve is that when android is connected to both my wifi and 3G, any call to private ip is directed to WiFi whereas any call to internet should use 3G.
Can this be done and how?
Is there a way to take data from Matlab Mobile without an internet connection? I have my computer and phone linked through USB and would like to use the GPS in my phone to keep track of the position of my car. Ideally the data would just flow from my GPS sensors to the Matlab App and then through the USB connection and into Matlab. I guess what I'm asking is is there a way to connect my phone and computer without using internet?
They just have to be in the same network. If you are on the go just use your phone as a wifi hotspot and connect to your computer. No internet required.
I'm developing a new android application in which i'm using ip webcam.when user clicks on a button ip web cam will open and it will trigger another phones application where i can watch the video of ip web cam. My problem is i'm getting the video only when i'm in the same network.If i changed to some other network it is not showing.I've searched for the solutions in the internet and i found about port forwarding.I tried that one by like this. If my local ip web cam address is nothing but devices ip address 192.168.1.15, and i'm using the port is 8080,so when i tried to connect with url "192.168.1.15:8080", from same network it is showing, from other network it is not showing.I'm using wireless network and Router is linksys, i opened my router's webpage and in "Application & Gaming ", i set "single port forwarding" by giving the application name, and ip address of the device(192.168.1.15), and port number 8080, and i enabled it.After saving, it is showing settings are successful. but i'm not getting the video.And i tried to check whether port is opened or not by using some port checking websites like "http://www.yougetsignal.com/", but it is always showing that port is closed. I checked some other networking sites saying that try with static ip address of router. I found my router's static (public) ip address by "whatismyip.com", and i tried with that one like "44.126.233.56:8080",still it is not showing the video. I tried with changing of ports like "6564" and "11100", still i'm not getting.So anybody please Help me to get this.
I hope I can help you here or at least point to some idea.
Your router defines the boundaries of the internet at your house by using an assigned IP (from your ISP) and using an internal IP address for the local network. The internal network IP address is intended to be in a range that the router would not "leak" to the outside - only indirectly by using something that is called NAT - network address translation. The problem that I am having with your question is that if your configuration is set for modem + Linksys and both are capable of processing NAT it will not work (NAT then NAT), your modem should be set for bridge mode and then use the NAT on the Linksys and configure the port triggering or forward as your device would function as game console. Hope this helps.
Thank you
