An ADB Implementation using WebUSB

This project is a TypeScript implementation of the Android Debug Bridge(ADB) protocol over WebUSB. The implementation inspired on the webadb.js, with the main difference being that implementation supports multiple concurrent streams.

This is not an exhaustive implementation of the protocol and hasn't been tested on a wide range of devices.

A non-exhaustive list of things that are not implemented:

• STAT: reads stats from the Android filesystem (file size, mode and time).
• SEND: writes a file to a device. Similar to adb push.

Usage

Connecting to a device

  const options: Options = {
    debug: true,
    useChecksum: false,
    dump: false,
    keySize: 2048,
  };

  const transport = await WebUsbTransport.open(options);
  const adbClient = new AdbClient(transport, options, keyStore);
  await adbClient.connect();

Downloading a file from the device (adb pull)

  const result: Blob = await adbClient.pull('/sdcard/my-video.mp4');

Sending shell commands

  const result: string = await adbClient.shell('uname -a');

Interactive shell

  const callback = (output: string) => {
    console.log('server: ' + output);
  };
  const shell: Shell = await adbClient.interactiveShell(callback);
  await shell.write('ls /sdcard\n');
  await shell.close();
