Receive the Intent

Every Activity is invoked by an Intent, regardless of how the user navigated there. You can get the Intent that started your activity by calling getIntent() and retrieve the data contained within the intent.

1. In the java/com.mycompany.myfirstapp directory, edit the DisplayMessageActivity.java file.

2. Get the intent and assign it to a local variable.

   Intent intent = getIntent();
   

3. At the top of the file, import the Intent class.

   In Android Studio, press Alt + Enter (option + return on Mac) to import missing classes.

4. Extract the message delivered by MyActivity with the getStringExtra() method.

   String message = intent.getStringExtra(MyActivity.EXTRA_MESSAGE);
