Capture screenshot from Android emulator

[deyanyanakiev]

Hello,
I was wondering if you could give me some advice on how to capture a screenshot from the android emulator.
I am working with protractor and appium for connecting to the emulator. Here is the code which I have so far:

var fs = require('fs'),
    adbClient = require('adbkit').createClient();

function writeScreenShot(data, filename) {
    var stream = fs.createWriteStream(filename);
    stream.write(new Buffer(data, 'base64'));
    stream.end();
}

describe('angularjs homepage todo list', function() {
  it('should add a todo', function() {
    browser.get('http://www.angularjs.org');

    browser.findElement(by.id('add-some-control'))
        .then(function (el) {
            return el.getLocation();
        }).then(function (loc) {
            return browser.executeScript('window.scroll(0,' + loc.y + ')');
        }).then(function () {
            return adbClient.listDevices();
        }).then(function (devices) {
            console.log(devices[0].id);
            return adbClient.screencap(devices[0].id);
        }).then(function (png) {
            writeScreenShot(png, 'screen.png');
        });

    var todoList = element.all(by.repeater('todo in todos'));
    expect(todoList.count()).toEqual(2);
  });
});
