android.content.ActivityNotFoundException: Unable to find explicit activity class

I am developing an android application. On the home screen, it has a button, on click of this an activity should be displayed. While testing the app, on click of the button, the app is giving the below error and the app got terminated.

E/AndroidRuntime(Number): java.lang.RuntimeException: Unable to resume activity {app package}: android.content.ActivityNotFoundException: Unable to find explicit activity class {activity class}; have you declared this activity in your AndroidManifest.xml?

The solution for this is,

Every activity created in android application should be configured in AndroidManifest.xml of the app. To do so, open AndroidManifest.xml and goto Application tab. Under Application Nodes, add all the activities.
