That's not the problem, he's reporting a compiler error. (He may yet
have that problem downstream of this one).
Darshan, what you've written is not valid Java syntax.
You mean one of these two constructors
ComponentName(<string>, <string>)
or
ComponentName(<context>, <class>).
What you've supplied as arguments are identifiers which aren't
defined.
A string is in double quotes. A class is referenced by the name of the
class followed by .class
And the context would be the activity. In this case, you'd write
intentsTest.this since your code is inside a nested class, but usually
you'd just write 'this' (no quotes).
So you either meant:
new CompnentName("com.darshan.demos", "com.darshan.demos.IntentsNew")
or
new ComponentName(intentsTest.class,
com.darshan.demos.IntentsNew.class)
I'd generally prefer the second -- that way the compiler can detect
any incorrect class name, and you can't get the package name wrong.
Also, I'll note in passing that your class name, "intentTest", doesn't
conform to convention. Normally, class names begin with a capital
letter. This convention is widespread and strong enough to be worth
paying attention to. Even if nobody else reads your code -- following
it will help you read other people's code and APIs. It is actually
quite rare to find Java code that doesn't follow this.
