Appium & Python: How to move to another app? - python-3.x

Question

I am making a testing bot with Python and Appium.
I need to extract the email of a button. I tired to extract href, but button are obviously something else than in smartphone applications.
So I click on this button which open my gmail with the New message window and the email in the "To" field.
SO I investigate and I could find only 1 tutoriel in Java :-(.
I found something else. SOmeone propose to instantiate new driver:
driver2 = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps2)
print("we setup driver2")
email = driver2.find_element_by_id("com.google.android.gm:id/to").text
But it stop immediately the browser. ANd Pycharm displayed this error:
Error Traceback (most recent call last): File

I am using unittest which instantiate one driver going to 1 app (where there si the email button), then I instantiate in the middle of the code a new driver.
But it bugs. And Icannot find anywhere an article or forum question about switching from 1 app to other app.
I prefer to let you te code of my bot:

Does anyone can help me please?

Answer 1

It looks like you're looking for start_activity function
The driver.start_activity method opens arbitrary activities on a device. If the activity is not part of the application under test, it will also launch the activity's application.
driver.start_activity('com.foo.app', '.MyActivity')
This way you should be able to switch between applications within the bounds of the same webdriver instance
You might also find Launch command useful as it is cross-platform approach allowing kicking off any installed application. The command is available via SeeTest Appium Extension.

Answer 2

It seems like you just need switch context, you facing web in gmail, try :
driver2 = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps2)
print("we setup driver2")
driver2.switch_to.context('WEBVIEW_1')
email = driver2.find_element_by_id("com.google.android.gm:id/to").text
Or
# switch to webview
webview = driver.contexts.last
driver.switch_to.context(webview)
And please try without new initilize driver2
Please read this reference and this.
