![]() That way the virtual directory tree is kept up to date which is reflected in the output of adb devices.Ĭurrently, termux-adb is limited to one USB device at a time but this can be improved in the future. In order to emulate this behavior, termux-adb also runs in the background, polls termux-usb periodically and sends any discovered file descriptors via a Unix Domain Socket connection to the injected library running along adb server. What you need to run the adb shell commands is a terminal emulator that can truly access the underlying Android file system, not just the Termux. There it will set up a virtual character device backed by the file descriptor obtained from termux-usb.īecause adb forks itself and runs in the background when you run it for the first time, it means it can scan for newly connected USB devices continuously. By design, Termux runs only (or is mostly) the Linux command line programs that you install from within Termux using apt or the newer 'native' package management interface, e.g. To avoid the need for patching adb source code, termux-adb uses LD_PRELOAD to inject a dynamic library that hooks a couple of libc functions and emulates access to /dev/bus/usb as if the corresponding directory structure was accessible. If it cannot access /dev/bus/usb, it just won't detect any connected devices. Of course, adb by itself doesn't know anything about termux-usb nor it can take raw file descriptors from command-line or environment. ![]() There is, however, Android API exposed by termux-usb utility which gives you a raw file descriptor of any connected USB device after manual approval by the user. This is mainly due to filesystem permissions required by adb when enumerating USB devices (traversing /dev/bus/usb/*). Termux has the android-tools package which contains adb (and fastboot) but it normally works on rooted devices only. make-release.sh to build and package all of them at once build individual components (termux-adb, adb-hooks, termux-fastboot) using.# Run "adb shell" and on adb shell run "sh /sdcard/run-as-termux. # Enable Debug Mode and ADB, connect you phone on PC, Download ADB Tools ![]() ![]() # Add this file on you /sdcard directory on you android Phone ![]()
