I have modfied your code, so that it becomes more redable and get executed easily
*** Settings ***

${APP_PACKAGE} com.xxx.android
${AUTOMATION_NAME} appium
${RESET_OFF} true
${AppAct} com.xxx.android.flavor.full.activities.HomeActivity
*** Test Cases ***

sleep 5s
Couple of Key points
appActivity was missing
Assuming appium server is running at 4723
Assuming Appium library is installed
