adbfs

A FUSE filesystem that uses goadb to expose Android devices' filesystems.

Features

• Read access to Android device filesystems through adb, without root. Of course, this is limited to files that are accessible to whatever user adb shell runs the shell as on the device.
• Experimental write support (run with --no-readonly). Notably, on OSX, Finder can't copy files into mounted directories (issue #34).
• Automounter daemon that detects when devices are connected and mounts them under a configurable directory.
• Communicates directly with adb server using goadb instead of delegating to the adb client command like most adb-based filesystems.

Quick Start

Installation

adbfs depends on fuse. For OS X, install osxfuse. Then run:

$ export GO15VENDOREXPERIMENT=1
$ go get github.com/zach-klippenstein/adbfs
$ cd `go list -f '{{.Dir}}' github.com/zach-klippenstein/adbfs`
$ ./install.sh

Let's mount some devices!

The easiest way to start mounting devices is to use adbfs-automount to watch for newly-connected devices and automatically mount them.

$ mkdir ~/mnt
$ adbfs-automount

You probably want to run this as a service when you login (e.g. create a LaunchAgent on OSX). For example, on OSX, paste this into ~/Library/LaunchAgents/com.adbfs-automount.plist (substituting "zach" for your own username, of course):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.adbfs-automount</string>
  <key>ProgramArguments</key>
  <array>
    <string>/Users/zach/go/bin/adbfs-automount</string>
    <string>--adb=/Users/zach/android-sdk/platform-tools/adb</string>
    <string>--adbfs=/Users/zach/go/bin/adbfs</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>KeepAlive</key>
  <true/>
  <key>StandardOutPath</key>
  <string>/Users/zach/adbfs.log</string>
  <key>StandardErrorPath</key>
  <string>/Users/zach/adbfs.log</string>
</dict>
</plist>

then run

$ launchctl load ~/Library/LaunchAgents/com.adbfs-automount.plist
$ launchctl start com.adbfs-automounter

Usage

Devices are specified by serial number. To list the serial numbers of all connected devices, run:

adb devices -l

The serial number is the left-most column. To mount a device with serial number 02b5c5a809117c73 on /mnt, run:

adbfs --device 02b5c5a809117c73 --mountpoint /mnt

Example:

$ adb devices -l
List of devices attached 
02b5c5a809117c73       device usb:14100000 product:hammerhead model:Nexus_5 device:hammerhead
$ mkdir ~/mnt
$ adbfs -device 02b5c5a809117c73 -mountpoint ~/mnt

adbfs-automount

adbfs-automount listens for new device connections to adb and runs an instance of adbfs for each device to mount it. Most arguments are passed through to adbfs, but there are a few arguments specific to the automounter:

--root: the directory under which to mount devices. If this is not specified, it will try to figure out a good path. On OSX, ~/mnt is used if it exists, else /Volumes. On Linux, it tries ~/mnt then /mnt.

--adbfs: path to the adbfs executable to run. If not specified, will search $PATH. The executable must be built from the same SHA as adbfs-automount, which will exit with an error if this is not the case.

--on-(un)mount: a command to run when a device is (un)mounted. Can be repeated to run multiple commands. E.g. --on-mount 'say $ADBFS_MODEL' --on-mount 'open $ADBFS_PATH' will speak the type of device and open it in Finder.
