NOTE: Of late, I have been getting requests for very trivial problems that many of you are facing in your day-to-day work. This blog is not to solve your "project" problems - surely not a "Support" site.
I just love to share my knowledge in my spare time and would appreciate any questions or feedback on the articles and code I have shared. I also do appreciate thought-provoking questions that would lead me to write more articles and share.
But please do not put your day-to-day trivial problems here. Even if you do, you most probably would not get a response here.

Android Developers Blog: Can I use this Intent?

We all know that the loose coupling provided by Android through intents is one of its most powerful features. It makes it possible for us to mix and match the use of activities between various applications as though they all belong to one.

However, when I want to invoke another application that has published an intent filter, I cannot always assume that the other application is available on the phone. So, I need to check its availability and then only enable the feature to call it.

This is very well explained in the link: Android Developers Blog: Can I use this Intent?
