How to access messaging feature of app(s) from other app? : I'd just like to know how to 1. Specify a "app chooser" to search for and give the user options of only apps that have a messenger feature and 2. how to access the messaging feature of other apps and display its data? Is it even possible? What api's/classes would I need to use/research? Would I have to write the code in anothee language and transfer it over? I'm currently working in android using java.
