I want to automate one android native like Netflix app but i am not able to take screenshot / record video. I tried with UIautomator/appium/katlon applications. Can anyone suggest me another tools by which i can automate same native android app.
It is not possible.
You can only automate those apps that are signed with your company's/team provisioning profile from their xcode build. The team will have to distribute this ipa/app file ready for your test (either the simulator version or for actual ios device - they are different build). Then once installed you will be asked to trust the app you installed.
Existing 3rd party apps are not possible as far as security is concerned.
