PY UIAutomator: Need Addition of Screenshot Watcher about uiautomator HOT 14 CLOSED

Hi @gokulakv,

It's not a good idea to take screenshot in watcher. The common way is to do it using test framework. e.g. if you are using nosetest, you can write a plugin to do it. Next is an example on its official website:
HTML Output Plugin. You can write your code to take screenshot on addError and addFailure methods.

Another way I am trying is to capture ui-not-found exception surround any device operation. You can look at the code at not-found-callback branch (not released). Next is sample code:

def my_call_back():
  d.screenshot('/path/to/screenshot.png') # take screenshot here
  return True  # True means not to call next callbacks

def setup_func():
  d.handlers.on(my_call_back)

def teardown_func():
  d.handlers.off(my_call_back)

@with_setup(setup_func, teardown_func)
def test_demo():
  '''my test...'''

Hope this can help you out.

Okie, what's the purpose of bundle.jar and uiautomator-stub.jar?
If I want to change Server code, how to compile these two jars myself?

from uiautomator.

bundler.jar is a bundle of all necessary libraries under libs directory. uiautomator-stub.jar is compiled from source code under src.

To compile it, you must follow the step on Readme#Build.

Oh is it good to include our own libraries into your source and use it for ourselves?
Our plan is to use quicksettings (UI) libraries written for our test-cases, into JSONServer, so to use in uiautomator.py and inturn in testcases, as we are not able to use both UI instance in SL4A and this Py UIAutomator

from uiautomator.

You only need to put source code under src folder and jar files under libs folder, and then build.

Sure thanks, Cool to work with your tool. Really sincere compliments from our team for this product. Appreciate your awesome work

And this handler works only when I add atleast one watcher for it, Why is it so?
Is it a mandate?

No. I received a lot of request for how to define customized watcher, so I added handler. It is only a PC side implementation to replace Watcher and can be used without watcher. I assume what you met is a syntax error...

from uiautomator.

No no, I clearly ran with and without Watcher,
This Handler runs only when there is atleast a dummy watcher, Observed Multiple times
P.S. There is no Syntax error came while running this, other than the Initial One to use self.my_callback

What in this case when I want to capture Screenshot of Obstacles that are suppressed using Watchers?

from uiautomator.

Could you please run below code in your PC, and check if you can see callback.... in console?

from uiautomator import device as d

def my_call_back(device=None):
  print 'callback....'
  return True  # True means not to call next callbacks

d.handlers.on(my_call_back)
d(text='Not Found').click()

from uiautomator.

NO I can't see callback.... in the console
And
//return True// statement
raised the following:
SyntaxError: 'return' outside function
SO COMMENTED this STATEMENT

from uiautomator.

So What's the problem/issue?
