Apps And Apk
Files
An Android app is an Android application. An app
is packaged in an APK file (Android application
package). The APK file contains the compiled Java
code and other resources like texts and images
for the Android application.
4
Activities

• An Android activity is a GUI component. It
  corresponds roughly to a window in a desktop
  application. Since mobile phone screens are
  small, an activity typically takes up the whole
  screen. If you open multiple activities they are
  stacked on top of each other. You cannot arrange
  activities side by side, like you can do with
  desktop windows.

5

Fragments

• In Android a fragment is a fragment of a total
  user interface. A fragment typically only takes
  up part of the screen. Fragments are used inside
  activities. Fragments can be reused within
  different activities.
• Fragments typically contains Views and View
  Groups inside them.

6

Views and ViewGroups

• Android GUI elements fall into three categories
  Activities, Views and ViewGroups. Activities are
  the screens / windows. Views are the individual
  GUI elements, like a TextView displaying a text,
  a Button that users can click on etc. ViewGroups
  are containers for Views. A ViewGroup groups a
  collection of Views together.
• Views and ViewGroups can be nested inside an
  activity or inside a fragment (which is again
  nested inside an activity).

7

Layout XML Files

• Activities, fragments and some ViewGroups can use
  XML files to define their layout and contents.
  The layout XML files specify what GUI components
  an activity or fragment contains, as well as
  styling of the GUI components (size, margins,
  padding etc.).
