Question

By default, an Android app uses a single thread, called the ________________, to display the user interface. Any task that can slow or stop the responsiveness of this should be run in a separate thread.

Answer 1

An Android app uses a single Main Thread, also known as the UI Thread, to manage the user interface. Lengthy operations should be performed in separate threads to prevent UI unresponsiveness and ANR errors, following the Android threading model for optimal app performance.

Step-by-step explanation:

By default, an Android app uses a single thread, called the Main Thread or UI Thread, to display the user interface. Any task that can slow or stop the responsiveness of this should be run in a separate thread. An Android app uses a single Main Thread, also known as the UI Thread, to manage the user interface.

Lengthy operations should be performed in separate threads to prevent UI unresponsiveness and ANR errors, following the Android threading model for optimal app performance.

Tasks that could potentially affect the app's performance, such as network operations or complex calculations, should be offloaded to background threads to prevent Application Not Responding (ANR) errors. This approach follows the threading model used in Android development to ensure smooth user experiences.
