android UiTestAutomationBridge null root node returned

I get below error when doing vc.dump call. It goes fine at times and randomly fails with this error.

ERROR: Offending XML: u'ERROR: null root node returned by UiTestAutomationBridge.\r\n' LoginTest failure (ExpatError('syntax error: line 1, column 0',),)

I am not sure if its emulator, device, AOSP unanimator jar or androidviewclient causing it.

I think it mostly happens when a dialog is shown on screen.

Miten.

Solution

  • It's an UiAutomator error. Instead of returning a valid XML containing the View dump it returns the error message:

    'ERROR: null root node returned by UiTestAutomationBridge.\r\n'

    Not an AndroidViewClient issue.
