why did this: the reason use kind of approach because want workflow wait @ node until video gets copied, @ same time want notified % of progress made while copying sent different application @ every 2s. problem faced: at random while executing workflow intermediate message catch event on boundary not registered , error first callback video copy application when tries correlate message event on boundary. their others ways making simple loop in camunda achieve same behavior but random error in case concern if 1 knows same issue or if better approach can me. the approach non-interrupted boundary event valid, maybe bit verbose. prefer on loop construct, have thought "just" updating process variable outside indicate status? not need bpmn element allow this. see example rest api on update of process variables: https://docs.camunda.org/manual/7.7/reference/rest/process-instance/variables/put-variable/ . same of course possible java api. at random while ...

is other android devices having leanback feature except androidtv? i want restrict app on play store android tv. so, have added manifest <uses-feature android:name="android.software.leanback" android:required="true" /> from "https://developer.android.com/training/tv/start/start.html#declare leanback support" is right way restrict androidtv on play store? declare app uses leanback user interface required android tv. if developing app runs on mobile (phones, wearables, tablets, etc.) android tv, set required attribute value false. if set required attribute value true, app run on devices use leanback ui. the way interpret this, limits app tv.
