Hi,
I am trying to do a userdebug build of GrapheneOS. I have successfully build production ("user") builds recently, but I am otherwise new to Android development.
This comment on hacker news is from a GrapheneOS developer (from what I can understand):
https://news.ycombinator.com/item?id=42521629#42536302
You should enable ro.adb.secure=1 for a userdebug build if you intend to use it in production to enable USB-based ADB authentication like a regular user build. [...]
The build guide does not mention anything about how to set ro.adb.secure=1.
This property is set in build.prop, I suppose. What's the procedure / where is the file, or command line option to use / at what point of the build process should I do it?
Many thanks!
