Mention the difference between class, file and activity in Android?

Answer»

The DIFFERENCE between them is as follows:

  • Class is a compiled FORM of a .java FILE that Android uses to produce an executable .apk file.
  • A file is a block of arbitrary information or resources used for storing information. It can be of any file type.
  • Activity is a single screen that represents GUI(Graphical User Interface) with which users can INTERACT in order to do SOMETHING like dial the phone, view email, etc.
