Web ADB

A simple webapp and API for managing and manipulating connected Android devices via the Android Device Bridge (ABD).

Requirements

The following are required on the host machine running Web ADB:

• Python 2.7
• Android SDK

Quick Start

• Clone this project to the host machine
• Run python <path-to-web-adb>/server.py --port=8888 --adb-path=<path-to-android-sdk>/platform-tools/adb
• Open http://localhost:8888 in a browser

Basic Usage

• Connected devices are listed in the table
• Selecting a device will display a panel below the table with more capabilities.
• The action buttons/images have hover text to help you guess what they do.
• Clicking on a screenshot will send a tap to the device and refresh the screeshot.

Details

I tried to keep this as minimal as possible. A single Python file acts as a very simple API server. In addition to several API routes, hiting the root will return a simple single-page webapp.

Commandline Arguments

• --port the local port to bind the server (defaults to 8080)
• --adb-path the path to the ADB binary
• --cert-file the path to a PEM file you want to use to enable HTTPS support

Routes

/ (GET, text/html)

returns the single-page webapp

/devices (GET, application/json)

returns a JSON array containing a JSON device object each connected device

[
  {
    "id": "<device-id>",
    "network": {
      "connected": (true|false),
      "ssid": "<wifi-name>"
    },
    "battery": {
      "status": "<range: 1 to 5>",
      "level": "<charge level>",
      "health": "<range: 1 to 7>",
      "plugged": "(USB|AC)"
    },
    "screen": {
      "width": "<XXXpx>",
      "height": "<YYYpx>",
      "density": "<integer density>",
      "orientation": "0|1"
    },
    "model": "<model-name>",
    "manufacturer": "<manufacturer-name>",
    "sdk": "<integer SDK level>"
  },
  {...}
]

/screenshot/:device_id (GET, image/png)

returns a PNG of the device screen

/logcat/:device_id (GET, text/plain)

returns a simple text dump of the logcat

/info/:device_id (GET, application/json)

returns a JSON device object for the given device

/key (POST, text/plain):

executes a keypress on the given device. takes a JSON object and returns a plain text status

{
  "device": "<device-id>",
  "key": "<key-code>"
}

/tap (POST, text/plain):

executes a tap on the given device at the given coords. takes a JSON object and returns a plain text status

{
  "device": "<device-id>",
  "x": "<x-location>",
  "y": "<y-location>"
}

/shell (POST, text/plain):

executes a shell command on the given device. takes a JSON object and returns a plain text status

{
  "device": "<device-id>",
  "command": "<shell-command>"
}

/reboot (POST, text/plain):

reboots the given device. takes a JSON object and returns a plain text status

{
  "device": "<device-id>"
}

Future Ideas

I threw this project together quickly to scratch a specific itch. Here are some ideas I'd like to think about for the future:

• Heartbeat monitoring to check the device status and connection. Maybe a health ping every 10 seconds.
• Start/Stop monitor for CPU, Network, and Memory usage. Use a simple chart for visualizing it.
• Wrap a few more ADB commands, like pull/push files and APK management.
• Capture video.
• Add swipe support.

Acknowledgements

Even though I try to minimize dependencies in the server code, I do use some 3rd party libraries in the single-page webapp, pulled in via CDN links:

• JQuery
• Bootstrap
• Handlebars
• Font Awesome
