Android app illegal xpath

i used spy to capture the XPath from the app
code:

int j=1
j++  

String path = '//hierarchy/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.FrameLayout[1]/android.widget.FrameLayout[1]/android.view.ViewGroup[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.LinearLayout[3]/android.view.ViewGroup[1]/android.widget.RelativeLayout[1]/android.widget.HorizontalScrollView[1]/android.widget.LinearLayout[1]/android.support.v7.app.ActionBar$Tab['+j+']/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]'

TestObject to = findTestObject('Android Sanity/Events/when')

to.findProperty('xpath').setValue(path)

Mobile.tap(to, GlobalVariable.TIMEOUT_LONG)



Error:

Test Cases/movies/android/headers/Verify Events Link redirection FAILED because (of) Failed to tap on element 'Object Repository/Android Sanity/Events/when' (Root cause: org.openqa.selenium.WebDriverException: Returned value cannot be converted to List<WebElement>: {stacktrace=UnknownError: An unknown server-side error occurred while processing the command.

    Hi pritam
     
    Use the below mentioned solution instead of /android.support.v7.app.ActionBar$Tab['+j+']. It might work for you.

    "//*[contains(name(), 'ActionBar' )]["+j+"]"
