Chrome version: 83.04103.101

I am searching solutions, but i haven't found nothing.

Answer 1

Do you develop script on Android Chrome, If you are control android chrome, you can check the chrome driver version in appium whether it is matched with android chrome version on your device. The chrome driver in appium should store the location like this:

C:\Users\xxx\AppData\Local\Programs\Appium\resources\app\node_modules\appium\node_modules\appium-chromedriver\chromedriver\win. 

This is the windows appium lcoation. Drag the chromedriver.exe into CMD, you can see the driver version.

Answer 2

The error in your log( Original error: No Chromedriver found that can automate Chrome '83.0.4103'. You could also try to enable automated chromedrivers download server feature ) means you have chromedriver browser compatibilities issue, the chromedriver in your mobile emulator and the chromedriver appium has is mismatch. To fix this issue, you need to follow below steps:

1. Download chromedriver version 83.0.4103, you can find it here https://chromedriver.chromium.org/

2. Delete existing appium chromedriver, which locate in this path if Windows(C:\Users\yourUsername\AppData\Roaming\npm\node_modules\appium\node_modules\appium-chromedriver\chromedriver\win)

3. Copy& paste the chromedriver version(83.0.4103) you downloaded

4. Run your test again
