This document discusses validation in mobile application development. It defines validation as verifying user-entered data to ensure it is valid and meets application requirements. This helps prevent errors and crashes. Validation techniques mentioned include input masks, data type checking, and regular expressions. The document stresses that validation is important for smooth application functioning and data protection, and that secure coding practices should be followed for implementation.

4. What is Validation in Android?
 Validation in Android is a process of verifying the data
entered by the user. It is used to ensure that the data is valid
and meets the requirements of the application. It is done to
ensure that the user does not enter invalid data, which could
lead to errors or crashes.
 Validation can be done in different ways, such as using input
masks, validating data types, and using regular expressions.
It is important to validate data before it is stored in the
database or used in the application.

5.  Validation is an important part of any application
development process. It ensures that the data entered
is valid and meets the requirements of the application.
This helps to prevent errors and crashes, and ensures
that the application runs smoothly.
 Validation also helps to protect the user’s data
Why is Validation Important?

6.  Validation in Android can be implemented using
various techniques, such as input masks, validating
data types, and using regular expressions. It is
important to validate data before it is stored in the
database or used in the application
.
 It is also important to use secure coding practices
when implementing validation.
