AdbOrc

AdbOrc makes it easy to create psuedo-distributed network of android devices. It is a simple wrapper around adb that allows you to easily share devices with other users on your network. Securely share your devices within your network for testing, debugging or development.

Overview

There are three modes of operation for a network node in AdbOrc:

  1. Supplier - A machine on the network that has one or more android devices attached to it. Supplier, as the name implies, supplies devices to the network. There can be any number of Suppliers on the network.

  2. Consumer - A machine on the network that wants to use one or more android devices. Consumer, as the name implies, consumes devices from the network. There can be any number of Consumers on the network.

  3. MarketMaker - A machine on the network that acts as a middleman between Suppliers and Consumers. MarketMaker is responsible for matching Suppliers and Consumers and handling all the metadata of the network. There is exactly one MarketMaker on the network. For Suppliers and Consumers, MarketMaker serves as a proxy for the network.

A system on the network can be operating in any combination of the above modes. For example, a system can be a Supplier and a Consumer at the same time. It can also be a MarketMaker and a Consumer at the same time.

Supplying devices to the network is as simple as joining the network as a Supplier and choosing the devices you wish to supply.

To use devices from the network, you need to join the network as a Consumer and list the available devices within the network. You can then choose the devices you wish to use and ask MarketMaker to reserve them for you. Once you are done using the devices, you can release them back to the network.

All reserved devices are available for use only to the Consumer that reserved them. The devices are available directly via adb. Device screen mirroring for reserved devices is also supported directly by AdbOrc via scrcpy.

All communications between Suppliers, Consumers and MarketMaker are encrypted using the Noise Protocol Framework. The encryption keys are generated using the X25519 curve and the ChaChaPoly cipher suite with Blake2s as the hash function. The XX_25519_ChaChaPoly_BLAKE2s handshake pattern is used.

By default, device communications within the network between Suppliers and Consumers are NOT encrypted. However, Suppliers can choose to encrypt device communications with Consumers using the same Noise protocol cipher suites (uses KK pattern). This is done by simply enabling secure_mode while joining the network as a Supplier.

Usage

Start the network by starting MarketMaker on a machine:

$ adborc marketmaker start

Join the network as a Supplier from another machine:

$ adborc supplier start <MarketMaker_IP>

# Or, if you wish to enable secure mode
$ adborc supplier start <MarketMaker_IP> --secure

# Supply specific devices to the network
$ adborc supplier supply --devices "<android_serial1>,<android_serial2>,..."

# Or, supply all connected devices
$ adborc supplier supply

Join the network as a Consumer from another machine:

$ adborc consumer start <MarketMaker_IP>

# List available devices
$ adborc consumer list-available

# Reserve devices
$ adborc consumer reserve <device_id>

# Use the devices via adb
$ adb shell

# Or, use the devices via scrcpy
$ adborc consumer scrcpy <device_id>

For a more detailed usage, see the command reference

Installation

From source

# Assuming you have the rust toolchain installed
$ cargo install --git https://github.com/mobi-nex/adborc.git 

# Or, if you want to build from local source
$ git clone https://github.com/mobi-nex/adborc.git
$ cd adborc

$ cargo install --path .

From crates.io

# Assuming you have the rust toolchain installed
$ cargo install adborc

Note: AdbOrc in Consumer/Supplier mode requires adb to be installed on the system. It also requires scrcpy to be installed on the system if you wish to use device screen mirroring. See dependencies section for more details.

From releases (Windows only)

You can download the latest release from here. The release contains all dependencies bundled, including adb and scrcpy. Just extract the archive and run adborc.exe on the command line from the extracted directory.

Dependencies

AdbOrc depends on the following:

  1. adb - Android Debug Bridge
  2. scrcpy - Optional, for screen mirroring

For MarketMaker mode, none of the above are required.

For Consumer mode to work, minimum version of adb required is 1.0.41.

Optionally, scrcpy can be used for screen mirroring. Minimum version of scrcpy required is 1.13.

For Supplier mode to work, minimum version of adb required is 1.0.41, with minimum revision number of 33.0.1.

Note: scrcpy is not required for Supplier mode.

You can override the default adb and scrcpy used by:

# Full path to the adb executable
$ adborc set-adb-path <path_to_adb>

# Full path to the scrcpy executable
$ adborc set-scrcpy-path <path_to_scrcpy>

See command reference for more details.
