Use an intent to send data to my activity

Question

I have a server running that notifies the user with a statusbar notification that opens my main activity, how can I pass data to my activity trough that intent?

Answer 1

Use Intent.putExtra(..):

intent.putExtra("keyName", "somevalue");

This method is overloaded and takes various types as second argument: int, byte, String, various arrays..

To get the data out use appropriate getXYZExtra(). For String this is:

getStringExtra(String keyName)
