3. Describe Layouts
The activity_main.xml file, which will be currently sure to MainActivity , describes the contents of the home monitor from the software. This basically means, it will probably portray the speak space.

Once the consumer has finalized in, MainActivity will receive a result as a purpose . To carry out they, it is vital that you bypass the onActivityResult() method.
When the outcome’s rule is RESULT_OK , it means the consumer possess closed in effectively. If yes, you have to call the displayChatMessages() strategy once again. Normally, call finish() to close off the application.
Now, possible operate the application and take a look at the sign-in and sign-up displays.
