Question

I was testing the first app (see http://developer.android.com/training/basics/firstapp/starting-activity.html)

at a point,I stuck..
it shows:

Multiple markers at this line
– MyFirstActivity cannot be resolved to a variable
– EXTRA_MESSAGE cannot be resolved or is
not a field

(see heading DISPLAY THE MESSAGE)

// I FOUND THE ABOVE GIVEN ERROR MESSAGE HERE

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

HOW CAN I RESOLVE THIS?
THANK YOU

You haven’t defined MyFirstActivity and EXTRA_MESSAGE.

Did you add public final static String EXTRA_MESSAGE = "com.example.myapp.MESSAGE"; as it says in the tutorial? Check that MyFirstActivity is the name of your activity as well.
