I am trying to automate a mobile application. I have configured katalon studio for mobile testing ( followed this step [https://docs.katalon.com/katalon-studio/tutorials/setting\_mobile\_application\_automation.html](https://docs.katalon.com/katalon-studio/tutorials/setting_mobile_application_automation.html) ) But every time i try to record or run sample test case I keep getting an error message: ![image](https://europe1.discourse-cdn.com/katalon/original/2X/1/1bcb78c5613fdb9b15995adf2d5d446cb418a422.png) ---

I am getting the same errors here with: Windows 8.1, Katalon 6.2.0 (by upgrade) (Appium 1.12.1 as stated in [https://docs.katalon.com/katalon-studio/new/version-620.html](https://docs.katalon.com/katalon-studio/new/version-620.html)), 1 Android emulator and 2 real Android devices. The difference for me is I am starting an application that was previously starting ok with Katalon 6.1.5 and Appium 1.7.2 ( **Which I can confirm it still functions as expected, I have rolled both of them back** ). I have also made a test with the default GIT Android test project that Katalon provides. Katalon 6.2.0 and Appium 1.12.1 are throwing the same error there also. So the default projects are not stable either.

Hi @Neacsu_Cornel, If you upgrade appium from v1.8.1 to v1.12.1. Please follow these manual instruction: - Manually remove `io.appium.uiautomator2.server.test` and `appium.uiautomator2.server` from your devices. - Manually delete folder C://\/.katalon/tools/android\_sdk and let Katalon download again. Thanks ---

My issue has been solved. Looks like there was a version with appium. I did my research and I found that it is recommended to user Appium version below 1.8.1. for Katalon. @Neacsu_Cornel Let me know if its the same with you as well. ---

@duyluong I confirm your tweaks solves the problem for both real devices and emulator. Appium 1.12.1 and XCode 10.2 is brilliant!!! Thank you for support and hard development effort! @poonampahari if you read my post and follow the link you will notice that latest Katalon Studio 6.2.0 now supports Appium 1.12.1. Cornel ---
