[jagadeeshkotha]

Hi guys,

i'm using driver.runAppInBackground(5) method to hide app in background, But how can i launch the app running from background

I'm using iOS

[Telmo_Cardoso]

Have you tried ?

launchApp()

[jagadeeshkotha]

Telmo,

App automatically launched after the time mentioned in runappinBackGround(5) method

Thx

[Telmo_Cardoso]

yes, that happens

[richa_gupta]

though it is not happening with ios8 ..any other alternative do we hv to achieve the same?

[richa_gupta]

@Telmo_Cardoso please Reply..

[Telmo_Cardoso]

Didn't test yet with ios8.

And I search for a issue and in fact there is one, if you think its related to appium, re-open as jlipps said.

Hi all,

Fighting the issue for a while now, iOS8.2, Appium 1.4.0. I see the issue on real device, not sure about simulators.
I have found a workaround provided by calabash. It works for me.
The original issue can be found at https://github.com/calabash/calabash-ios/commit/6935245605d1fd44c223155972703e89247857ec

Apparently retrying the uia command does the trick.

I replaced the original

driver.runAppInBackground(2);

with

JavascriptExecutor jse = (JavascriptExecutor) driver;
jse.executeScript("var x = target.deactivateAppForDuration(2); var MAX_RETRY=5, retry_count = 0; while (!x && retry_count < MAX_RETRY) { x = target.deactivateAppForDuration(2); retry_count += 1}; x");

@adrianmatean - Great solution !!

many thanks

[igal_epshtein]

@adrianmatean - now I just saw that the solution is great for iOS 8 , but it doesn't work on iOS 9+

getting the next error :

Agreed - the target.deactivateAppForDuration technique does not work on iOS 9.1 for me. Same error as mentioned above

UPDATE:

• Still not working with iOS 9.2.1 and Appium 1.4.13.
  The Appium server logs show the same error:

RunAppInBackground actually relaunches the app, but I want it to resume the same screen. How to do it?
sendKeyEvent(3) does send it to home but how to come to foreground to resume the same screen?

[Vallabhaneni_Rakesh]

@adrianmatean @Telmo_Cardoso @jagadeeshkotha

runappinBackGround(5) is working for me , here after the app launches i want to be script must start running
But it was saying activity in the screen is not matching

Please help me out to handle this situation?

This is a thread for iOS Appium; I suggest you open a new thread for Android Appium so as to not confuse the issue.

[shilpi]

it reopens the app but app does not start from same page where we have closed it.
