Tabbed Applications in Android

Sometimes, we want to wrap multiple views in a single window and navigate through them with a Tab Container. This can be done in Android using TabHost control.

There are two ways to use a TabHost application in Android:

1. Using the TabHost to navigate through multiple views within the same activity.
2. Using the TabHost to navigate through Actual multiple Activities using intents.

We will explain both ways through this tutorial.
