Capture the layout of all screens - Android App

Question

I want to test android apps for accessibility violation. Is it possible to use uiautomator api and monkeyrunner api to capture the layout of all screens?

You can simply use AndroidViewClient's dump:

$ dump --help
usage: dump [OPTION]... [serialno]

Options:
  -H, --help                       prints this help                             
  -V, --verbose                    verbose comments                             
  -v, --version
  -I, --ignore-secure-device       ignore secure device                         
  -E, --ignore-version-check       ignores ADB version check                    
  -F, --force-view-server-use      force view server use (even if UiAutomator present)
  -S, --do-not-start-view-server   don't start ViewServer                       
  -k, --do-not-ignore-uiautomator-killed don't ignore UiAutomator killed              
  -w, --window=WINDOW              dump WINDOW content (default: -1, all windows)
  -i, --uniqueId                   dump View unique IDs                         
  -x, --position                   dump View positions                          
  -d, --content-description        dump View content descriptions               
  -c, --center                     dump View centers                            
  -f, --save-screenshot=FILE       save screenshot to file                      
  -W, --save-view-screenshots=DIR  save View screenshots to files in directory  
  -D, --do-not-dump-views          don't dump views, only useful if you specified -f or -W

In you case, probably

$ dump -d

is enough.

EDIT

If you want something more complex than just saving the logical content of the screen, you can use culebra (another tool in AndroidViewClient) that allows you to generate automated tests using a GUI:

$ culebra -UG -o mytest.py

You can interact with the mirror representation of the device screen in culebra's main window to generate the test. Save it. Run it on any device, even a completely different one.
