I have written the code for highlighted box still not able to find the particular element, in question dashboard i came across one instructor he also not able to find the solution, he gave me his email id to resolve the issue but didn’t find any solution.
driver.findElement(By.xpath("//android.widget.HorizontalScrollView[@index=‘1’]/android.widget.LinearLayout[@index=‘0’]/android.widget.Button[@index=‘1’]")).click();
I’m sharing drive link because for security reason I can’t send the .apk file directly.
