Dear supporter

would you pls share me some guide on this ? I can not run iperf3 on my Android device? both as client and server.

" unable to create a new stream: No such file or directory " thanks.

There may be a firewall/NAT issue, but first you should try using a newer (3.17.1) version of iperf3. Android pre-built versions are available at: https://github.com/davidBar-On/android-iperf3.

Even though Android is not an officially supported platform, I'm pretty sure we did some changes since the version you're running to improve Android compatibility.

I recently faced similar challenges trying to test UDP performance from Android devices.

To solve that, I ended up building a native Android app — CellularLab — that wraps iPerf3 via JNI and gives you full TCP/UDP/bidirectional testing right from your phone. It includes a clean UI, command mode, and even AI log analysis using Gemini.

Here’s a blog I wrote on how I compiled iPerf3 for Android using CMake + JNI: 👉 Compiling iPerf3 in Android – A Practical Guide

Hope this helps others trying to do similar testing on mobile!

@Abhi5h3k, as your implementation should be useful for other Android users, I added a eference to your implementation in my prebuilt android-iperf3 repository (although it doesn't have many followers ..).

Thanks a lot for the mention, @davidBar-On 🙏 I'm glad you found the Android implementation helpful, and I appreciate the link to the article in your repo.

Hopefully this makes it easier for others trying to integrate iperf3 into Android apps. Looking forward to any feedback or contributions from the community as it evolve 🙂
