Unable to Start app on Kobiton devices but it works sometimes NullPointerException Cannot invoke getHeight because getStatusBar is null

Mobile Testing

Hi, I’m getting Unable to Start app on Kobiton devices but App does start sometimes. Using KS version 9.0, Appium v1.17.1

I’ve setup the KS/Kobiton integration and tested the connection successfully.

When I run my script and select to Run on a Kobiton device and select a device from the list I am getting a Unable to Start App and the issue is caused by NullPointerException. Even though this fails the Kobiton device loads the app.

Here is the error:

Hi @mlbfan10 ,

                 Looks like you are able to execute with 1st device successfully, however i can see other devices you need to select in the select device popup, that's why it's failed for those devices

Regards
Vinayak

Hi, @vinayak_joshi1 thanks for response. The images are just to show the integration with Kobiton is working and that it’s failing when I try to run on a device from the Kobiton device dropdown. After selecting a device it fails except for a couple Android V10 phones that work when selected from the dropdown which is what the second screenshot is trying to show.
