How to open one application from another?

[Markovic]

I would like to open my other app on button click if users have it instaled on their phones or take them to Store if they dont. Can someone help me please?

U need to create a Uri association of your other apps and then call in from a deep link uri from your App that will search the host phone for that particular app an launch it. If not found it will navigate u to the store for downloading.
