Recall the application code

Let's rewind to some of the things we wrote during application development.

Elements in the PhoneCallApp

• Textbox to enter phone number
• CALL button to call
• A text that gets displayed if the user taps on the CALL button without entering a number
• A confirmation dialog box that appears when user taps on the CALL button after entering a number

User interactions in the PhoneCallApp

1. Enter a number in the text box
2. Tap the CALL button
3. Tap on OK or Cancel in the confirmation dialog box
