AFAICR Android is responsible for calling onCreate in response to your activity not existing. Remember your app is more than an activity. It may have zero or many activities. 
that was also my understanding, that Android OS is responsible to know
if onCreate or onNewIntent should be called for these config in Android
Manifest:

android:launchMode="singleInstance" android:taskAffinity=""

taskAffinity is important to be used. see this great blog:
https://inthecheesefactory.com/blog/understand-android-activity-launchmode/en


'singleInstance' works as expected per ex. from Fotos App, Download App,
MS Word, ... if my App is launched, onNewIntent was used
have no idea why some very specific apps always call onCreate() to send
Files via action.SEND or action.VIEW

(will do some more tests with 'singleTask')
