MR_AndroidViewClient: Getting Browser’s HTML page source

Standard Android Browser does not provide an option in its menu to view the HTML page source. Some workarounds like installing apps and then usingShare page from
Browser's menu has been described and also the use of Javascript and JQuery to add to a page has been detailed, but we are hungry for more. Needless to say, all these methods involve some manual step so I felt the need to find a completely
automatic way of doing it.

Of course, to do it I would resort to our old pal
AndroidViewClient. This is a very interesting example of its use because it lies far from testing and application or UI.

And so, without further ado, let me introduce you to the code...

#! /usr/bin/env monkeyrunner'''Copyright (C) 2012  Diego Torres MilanoCreated on Oct 12, 2012@author: diego'''import reimport sysimport os# This must be imported before MonkeyRunner and MonkeyDevice,# otherwise the import fails.# PyDev sets PYTHONPATH, use ittry:    for p in os.environ['PYTHONPATH'].split(':'):        if not p in sys.path:            sys.path.append(p)except:    passtry:    sys.path.append(os.path.join(os.environ['ANDROID_VIEW_CLIENT_HOME'], 'src'))except:    passfrom com.dtmilano.android.viewclient import ViewClientfrom com.android.monkeyrunner import MonkeyRunner, MonkeyDeviceVPS = "javascript:alert(document.getElementsByTagName('html')[0].innerHTML);"PACKAGE = 'com.android.browser'ACTIVITY = '.BrowserActivity'COMPONENT = PACKAGE + "/" + ACTIVITYURI = 'http://dtmilano.blogspot.com'device, serialno = ViewClient.connectToDeviceOrExit()device.startActivity(component=COMPONENT, uri=URI)MonkeyRunner.sleep(3)vc = ViewClient(device=device, serialno=serialno)device.drag((240, 180), (240, 420), 10, 10)url = vc.findViewByIdOrRaise('id/url')url.touch()MonkeyRunner.sleep(1)device.press('KEYCODE_DEL', MonkeyDevice.DOWN_AND_UP)for c in VPS:    device.type(c)device.press('KEYCODE_ENTER', MonkeyDevice.DOWN_AND_UP)MonkeyRunner.sleep(3)vc.dump()print vc.findViewByIdOrRaise('id/message').getText().replace('\\n', "\n")device.press('KEYCODE_BACK', MonkeyDevice.DOWN_AND_UP)

And now a brief explanation of the most important pieces of this script.

1. Shebang, you know, to invoke monkeyrunner as the interpreter. I don't have to tell you more (if you are a poor Windows user you may have to invoke monkeyrunner from command
   line, I feel sad for you)
2. Some comments and imports
3. Read PYTHONPATH just in case you are using Eclipse and Pydev (this has been explained in thispost)
4. Then use ANDROID_VIEW_CLIENT_HOME environment variable to findAndroidViewClient in your system
5. Some constants defined. VPS is the actual javascript to obtain the page source
6. The standard way of connecting to the device or emulator in AndroidViewClient. This handles errors and timeout automatically solving many problems you find with bare monkeyrunner
7. We start Browser
8. Drag a bit to make the URL visible in case the page has scrolled
9. Next, we find the View with ID id/url, which you know, contains the URL
10. We touch to focus
11. And type the javascript in VPS followed by ENTER
12. By that time the alert dialog should be on screen so we take a new dump
13. Now we find the View with ID id/message which contains theHTML and print it
14. Finally, we press BACK to dismiss it

I hope you have enjoyed it as much as I did and this help you find new ways of using AndroidViewClient.P.S. This script will be part of AndroidViewClient source code distribution examples
