adbkit-monkey

adbkit-monkey provides a Node.js interface for working with the Android monkey tool. Albeit undocumented, they monkey program can be started in TCP mode with the --port argument. In this mode, it accepts a range of commands that can be used to interact with the UI in a non-random manner. This mode is also used internally by the monkeyrunner tool, although the documentation claims no relation to the monkey tool.

Getting started

Install via NPM:

npm install --save adbkit-monkey

Note that while adbkit-monkey is written in CoffeeScript, it is compiled to JavaScript before publishing to NPM, which means that you are not required to use CoffeeScript.

Examples

The following examples assume that monkey is already running (via adb shell monkey --port 1080) and a port forwarding (adb forward tcp:1080 tcp:1080) has been set up.

Press the home button

var assert = require('assert');
var monkey = require('adbkit-monkey');
 
var client = monkey.connect({ port: 1080 });
 
client.press(3 /* KEYCODE_HOME */, function(err) {
  assert.ifError(err);
  console.log('Pressed home button');
  client.end();
});

Drag out the notification bar

var assert = require('assert');
var monkey = require('adbkit-monkey');
 
var client = monkey.connect({ port: 1080 });
 
client.multi()
  .touchDown(100, 0)
  .sleep(5)
  .touchMove(100, 20)
  .sleep(5)
  .touchMove(100, 40)
  .sleep(5)
  .touchMove(100, 60)
  .sleep(5)
  .touchMove(100, 80)
  .sleep(5)
  .touchMove(100, 100)
  .sleep(5)
  .touchUp(100, 100)
  .sleep(5)
  .execute(function(err) {
    assert.ifError(err);
    console.log('Dragged out the notification bar');
    client.end();
  });

Get display size

var assert = require('assert');
var monkey = require('adbkit-monkey');
 
var client = monkey.connect({ port: 1080 });
 
client.getDisplayWidth(function(err, width) {
  assert.ifError(err);
  client.getDisplayHeight(function(err, height) {
    assert.ifError(err);
    console.log('Display size is %dx%d', width, height);
    client.end();
  });
});

Type text

Note that you should manually focus a text field first.

var assert = require('assert');
var monkey = require('adbkit-monkey');
 
var client = monkey.connect({ port: 1080 });
 
client.type('hello monkey!', function(err) {
  assert.ifError(err);
  console.log('Said hello to monkey');
  client.end();
});

API

Monkey

monkey.connect(options)

Uses Net.connect() to open a new TCP connection to monkey. Useful when combined with adb forward.

• options Any options Net.connect() accepts.
• Returns: A new monkey Client instance.

monkey.connectStream(stream)

Attaches a monkey client to an existing monkey protocol stream.

• stream The monkey protocol Stream.
• Returns: A new monkey Client instance.

Client

Implements Api. See below for details.

Events

The following events are available:

• error (err) Emitted when an error occurs.
  • err An Error.
• end Emitted when the stream ends.
• finish Emitted when the stream finishes.

client.end()

Ends the underlying stream/connection.

• Returns: The Client instance.

client.multi()

Returns a new API wrapper that buffers commands for simultaneous delivery instead of sending them individually. When used with api.sleep(), allows simple gestures to be executed.

• Returns: A new Multi instance. See Multi below.

client.send(command, callback)

Sends a raw protocol command to monkey.

• command The command to send. When String, a single command is sent. When Array, a series of commands is sent at once.
• callback(err, value, command) Called when monkey responds to the command. If multiple commands were sent, the callback will be called once for each command.
  • err null when successful, Error otherwise.
  • value The response value, if any.
  • command The command the response is for.
• Returns: The Client instance.
