What is the purpose of the 'Handler' class in Android?ATo handle user input eventsBTo manage background tasksCTo control the order of execution of tasksDTo define layout
Solution
The purpose of the 'Handler' class in Android is to manage background tasks and control the order of execution of tasks. It allows you to send and process Message and Runnable objects associated with a thread's MessageQueue. Each Handler instance is associated with a single thread and that thread's message queue. When you create a new Handler, it is bound to the thread / message queue of the thread that is creating it -- from that point on, it will deliver messages and runnables to that message queue and execute them as they come out of the message queue. Therefore, the correct answers are B and C.
