How to change activity in appium android

Hi,
I am using appium to automate native app. For the application launcher activity name is HomeActivity and it works fine if user logged in and redirect to home screen .

if user not logged in it redirects to welcome screen. In this case i am using HomeActivity to launch the app even app launches successfully with error as
“A new session could not be created. (Original error: com.medpresso.android.ui/.HomeActivity never started. Current: com.medpresso.android.ui/com.skyscape.android.ui.WelcomeActivity) (WARNING: The server did not provide any stacktrace information)”

Please help!!!. Please provide code to change activity.

Dattatray,
Fror me it’s not about code, it’s about test cases…
You have two scenarios: one with the fresh/first install and another with app in use.

For fresh/first install call you script with APP capability.
For the app in use set the activity capability.
