  1. Describe android Activities in brief.

    Activity provides the user interface. When you create an android application in eclipse through the wizard it asks you the name of the activity. Default name is MainActivity. You can provide any name according to the need. Basically it is a class (MainActivity) that is inherited automatically from Activity class. Mostly, applications have one or more activities; and the main purpose of an activity is to interact with the user. Activity goes through a number of stages, known as an activity’s life cycle.


    package com.example.careerride; //Application name careerride
    import android.os.Bundle; // Default packages
    import; // Default packages
    import android.view.Menu;
    public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
    publicbooleanonCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(, menu);
    return true;


    When you run the application onCreate method is called automatically.
