Why should you enable hardware acceleration for the emulator?

Hardware acceleration uses your computer's CPU features to make the emulator run faster and smoother, improving app testing speed.

What is the purpose of the Android Emulator's snapshot feature?

Snapshots save the emulator's current state so you can quickly resume testing later without restarting the emulator from scratch.

advanced

How can you simulate different network conditions in the Android Emulator?

The emulator lets you change network speed and latency settings to test how your app behaves on slow or unstable connections.

What tool in Android Studio do you use to manage emulators?

A AVD Manager

B SDK Manager

C Device File Explorer

D Logcat

The AVD Manager is the tool used to create and manage Android Virtual Devices (emulators).

Which system image should you choose for the emulator?

A Any image, it does not matter

B Only images for physical devices

C Only images with Google Play Store

D The latest Android version compatible with your app

Choose the latest Android version that your app supports to test compatibility.

What does enabling hardware acceleration do for the emulator?

A Improves emulator speed and performance

B Prevents app installation

C Disables graphics rendering

D Slows down the emulator

Hardware acceleration uses your computer's CPU features to speed up the emulator.

How can you quickly restart your emulator from a saved state?

A Clearing app data

B Reinstalling the emulator

C Using the snapshot feature

D Restarting Android Studio

Snapshots save the emulator state for quick restart.

Which feature helps test app behavior on slow internet in the emulator?

A Battery saver mode

B Network speed simulation

C Screen rotation

D GPS simulation

Network speed simulation lets you test apps on different internet speeds.
