HackRF Test

Independent Agent

About this app

Plug the HackRF into the USB port and use this app to capture and replay signals from frequencies within the range of 1 Mhz to 6 Ghz. The original source code came from Dennis Mantz at https://github.com/demantz/hackrf_android. This version includes GUI buttons and preselected frequency options, as well as , targets the Android SDK 25 and greater. In order to transmit, uncheck amplifier, check antenna power, turn the LNA slider all the way down and turn the VGA all the way up.

Ratings and reviews

This would be great, but I can't access the files it saves. Even though it saves it to the emulated SD card, the folder it's in /Android/data is now a protected folder under Android 13. It can no longer be accessed by other apps without rooting the phone now. And sadly, your app doesn't let me change the folder that the files are saved from, so that I can load/save to an unprotected folder. That's why I'm only rating your app 3/5 stars. You desperately need to update this app for Android 13.

I hate to rate things low but for me this app won't work at all. Sure it starts up but even with my new hackRF device and USB plugged carefully into my phone (and I've replugged it in several times to ensure it's a good connection) it will not do any tests or allow me to select anything. Even opening the log says "unable to open the log". I have a brand new ASUS ROG 6 Android phone. App needs work. Currently not working on Android. RFAnalyzer works fine with my HackRF so it's clearly this app.

This was working great until the update in October. Now it's saying "Check if USB driver needed or plug in the HackRF !" - Other SDR apps using the rtl-sdr driver are working fine. I've tried with and without the rtl-sdr driver and get the same result. An older APK I side-loaded a long time ago is still functioning. Let me know if I can help troubleshoot. Same behavior on Pixel 3XL and Note 20 Ultra 5G.

What’s new

Permissions broke on Android 13, because Android 13 does not accept permissions for WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE.
Adding Android 13 permissions for READ_MEDIA_IMAGES, READ_MEDIA_AUDIO and READ_MEDIA_VIDEO". Adding check with big if/else for Build.VERSION.SDK_INT < Build.VERSION_CODES.TIRAMISU rather than invasively changing the code structure.
