💡 Hint

Common Mistakes

Using commands like 'start' or 'run' which are not valid emulator options.

Not specifying the exact AVD name.

The command 'emulator -avd Pixel_5_API_30' starts the emulator with the specified virtual device name.

Using 'devices' which is not recognized by the emulator command.

Using 'images' or 'emulators' which are invalid options.

Fix the error in the command to start the emulator with a cold boot.

Android Kotlin

emulator -avd Pixel_5_API_30 [1]

Drag options to blanks, or click blank then click option'

A-no-boot-anim

B-wipe-data

C-no-snapshot-load

D-cold-boot

💡 Hint

Common Mistakes

Using '-cold-boot' which is not a valid emulator option.

Using '-wipe-data' which erases user data instead of just cold booting.

The option '-no-snapshot-load' forces the emulator to start fresh without loading a saved snapshot, effectively a cold boot.

Fill both blanks to correctly start the emulator with a specific scale and no audio.

Android Kotlin

emulator -avd Pixel_5_API_30 [1] [2]

Drag options to blanks, or click blank then click option'

A-scale 0.75

B-no-audio

C-no-window

D-gpu swiftshader_indirect

💡 Hint

Common Mistakes

Using '-no-window' which hides the emulator window.

Using GPU options which are unrelated to scale or audio.

The option '-scale 0.75' sets the emulator window scale to 75%, and '-no-audio' disables audio output.

5fill in blank

hard

Fill all three blanks to create an AVD with a specific name, device, and system image using the avdmanager command.

Android Kotlin

avdmanager create avd -n [1] -d [2] -k "system-images;android-30;google_apis;x86"

Drag options to blanks, or click blank then click option'

Bpixel

Cpixel_xl

DPixel_5

💡 Hint

Common Mistakes

Using device names instead of device ids.

Mixing up the order of name and device options.

The command creates an AVD named 'MyEmulator' using the device 'Pixel_5' and the system image for Android 30 with Google APIs. The device id is 'pixel'.
