What is the purpose of using Intent.createChooser() in StartActivity() while sending email in Android -


Whenever we need to send an email to Android, we use the registered e-mail using Intent.ACTION_SEND as below. Mail application will invoke 

  intent = new intent (Intent.ACTION_SEND); StartActivity (Intent.createChooser (i, "Send Mail ..."));

I suspect that we need to use Intent.createChooser in startActivity instead of using startActivty (i) ? Intent.createChooser () ?

There is no specific reason to use AFAIK if you have intent. If you use , then there are three different types:

  1. You can specify the title of the selector dialog to make it more clear.

  2. The system will always display the selector dialog, which has also chosen the user default.

  3. If your intent Intent.createChooser does not match any activity, the system will still see a dialog with the specified title and an error Message No application can perform this action . Or for general intention, you may get an Android Runtime error: By: Android Contact Activity Noout Expansion: No activity was found to control intents.
