android: how do i open another app from my app?
- by mtmurdock
I understand how to use intents and startActivity() when opening another activity within my own app, but how do you start a different app? specifically:
-how do you determine if the user has the needed app installed on their device?
-how do you start that app?
-how do you pass parameters to that app?
-how do you find all this info out for a specific app (say Adobe reader, or google maps)?
