Accessing public methods of Activity

Question

I am new to android development and have a confusion that if an activity( a class extends Activity) has some public methods, can we access these public methods outside that activity.

Answer 1

Yes. public methods are... public. This means that they're accessible from anywhere.

Answer 2

Yes, you may. Activities are just like any other classes in Java.

Yet, you should be careful where and when do you call them, since they might not be exist or not in correct state at a specific time.

Answer 3

Not sure of what you want to achieve, but yes you can pass a reference of the activity to the caller, just as you would with any object, and call its public methods.
