Hi Rocky,
There might be a mismatch between the package name and the activity name in your settings.
There are some DesiredCapabilities you can set that might help you get around this. In your Project->Settings menu, go to Execution->Default->Mobile->Android.
Add new entries for appPackage, appActivity, appWaitActivity, and appWaitDuration. Here’s a description of what those activities mean: http://appium.io/docs/en/writing-running-appium/caps/
When done, it should look something like this (substituting mycompany for the actual company code in the package).
Name Type Value
appWaitActivity String com.mycompany.*
appPackage String com.mycompany.app
appActivity String com.mycompany.Login
appWaitDuration Number 30000
Hope this helps,
Chris
