Aeeeiii...
So... A ComponentName is the name of a component. The name of a component
is simple the tuple of String manifest package name, and String Java class
name.
That is, if you have an AndroidManifest with package "com.example.foo" and
Activity class in there com.example.foo.MyClass, then formally a component
name for this is:
new ComponentName("com.example.foo", "com.example.foo.MyClass").
All of the other constructors for ComponentName are simply conveniences that
extract these two strings from what you give them. For example, when you
are passing in a Context, it is using Context.getPackageName() to find the
first string. When you are passing in a Class, it is using Class.getName()
to find the second string.
