The keyword "Switch Application" #82

BabauHo · 2015-12-17T06:56:09Z

Hi
I use the keyword "Switch Application" and follow the example:

${appium1}= Open Application http://localhost:4723/wd/hub alias=MyApp1 platformName=Android platformVersion=6.0 deviceName='' app=C:/XXXX/app1.apk
${appium2}= Open Application http://localhost:4725/wd/hub alias=MyApp2 platformName=Android platformVersion=6.0 deviceName='' app=C:/XXXX/app2.apk
Capture Page Screenshot Checkit0.jpg
Switch Application ${appium1}
Capture Page Screenshot Checkit1.jpg
Sleep 3s

After execute "Switch Application" and execute "Capture Page Screenshot".

The log return
" Keyword 'Capture Page Screenshot' could not be run on failure: KeyError: 'error' "

What's wrong with my usage?

I'll appreciate any help!

Thanks!

Could you provide some appium server log?

@BabauHo does this problem still exist?

semutmerah · 2016-09-01T04:45:49Z

Hi,

Currently, I am having a problem with "Switch Application" keyword too, but I don't know if it is the same problem or not.

My code is same as the example, but it looks like the app isn't really switched, it just stay on the second app, but then the test is marked as PASS.

My env:
appium 1.5.3
robotframework 3.0.0
robotframework-appiumlibrary 1.3.7

I am using a device with android 5.1.1

server log (from first app):

Looks like that both of your apps are running on the same device, this is not supported.

I think that KW is a bit misleading (the name and the documentation), it's not really switching between applications but actually switching between appium sessions.
If you have both sessions pointing to the same device, the switching doesn't really do anything on the device itself, after the switch you just talk to the device using different appium server.
I could also imagine that this will cause problems with appium itself because those 2 appium servers try to talk to the same appium bootstrap on the device...

In short: the Apps must run on different devices.

Supported: Device-A running App-1 and Device-B running App-2
Supported: Device-A running App-1 and Device-B running App-1
Not Supported: Device-A running App-1 and Device-A running App-2

For Example: you could test WhatsApp message sending from one device to another device.

However it would be a cool feature to switch between applications on the same device. This should be possible using appium but would need a completely different implementation approach where the switching just brings the started app to the foreground.

Hi yahman72,

Got it.
Thanks for your response.

Best regards,

Hi everyone,
I am using also Switch Application for a OTP message to connect to a wifi network. I am using only one Android device and my setup is as follow:

go to the website enter the mobile number OK
go to the SMS app (with Start Activity) and read the OTP OK
Switch Application ${chrome} OK but chrome is not displayed (SMS app is still on front) but the OTP worked because i am connected to wifi. I also tried to hardcode a dummy OTP and the wifi didn't connect.
go to any website to check if i have internet working OK.
So from what @yahman72 said it shouldn't work. Why Switch Application works but doesn't show the chrome and does everything in background ? Is it possible to display the application with Switch Application ?
Thank you

yahman72 · 2018-01-03T13:42:23Z

No, it's not possible to switch the application as mentioned "Switch Application" should actually be called "Switch Session" because it just switches between appium sessions, not between applications = it just automates the application that's on front.

You could try to bring the other app to front by using "start activity"

jerem0808 · 2018-01-03T13:54:32Z

Thank you for your answer. Ok I see but i'm not sure to understand why it does work then ?

yahman72 · 2018-01-03T14:09:44Z

what do you mean by "it works"?

jerem0808 · 2018-01-03T14:14:46Z

i mean that i was able to launch chrome with switch application and to enter the correct password in the corresponding field. I know it has worked because the mobile was connected to the wifi.
the splash page sends a password by SMS and then i am able to enter this password back to Chrome with Switch Application. But this process is "hidden" I don't see the password being entered because Chrome is not displayed
EDIT:
The problem with Start Activity is that i need to switch the context back to webview (namely: Switch To Context CHROMIUM) but this doesn't work and generates an error
ChromeDriver is not associated with a window
and then it resets chrome

yahman72 · 2018-01-03T14:31:43Z

oh? - I don't think it should work at all, but appium behaves a bit oddly with the "start activity".
Maybe the chrome still has somehow the focus...

Did you try also without the "switch application"? in this case it does nothing (i.e. it should also work without it).

If you really want to see the chrome then do it like this

go to the website enter the mobile number
go to the SMS app (with Start Activity) and read the OTP
send BACK keyevents until you see chrome again

jerem0808 · 2018-01-03T14:43:17Z

You're absolutely right it works also without Switch application.
Thank you for your help
