Android avd emulator - how to save "Do you want to save the current state for the next quick boot?" in config.ini file

Question

When creating an avd, starting it for the first time and then trying to close the emulator, the user will be prompted with a dialog reading:

Do you want to save the current state for the next quick boot?

Note: Saving the snapshot may take longer because free RAM is low.

I would like to save this parameter, before starting the emulated device, within its config.ini file.

However I'm not clear on which option it is.

Things I tried: Adding these lines to the config.ini

fastboot.chosenSnapshotFile=
fastboot.forceChosenSnapshotBoot=no
fastboot.forceColdBoot=no
fastboot.forceFastBoot=yes

Creating an additional file within the config.ini directory of the avd called quickbootChoice.ini that simply reads:

saveOnExit = true

Non of which helped, on every first shutdown of the emulated device this dialog pops up...

Thanks in advance

@Adah any idea how to resolve this? My CI won't progress due to this dialog – Downey

Answer 1

According to https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android/android-emu/android/skin/qt/tool-window.cpp the popup does not appear if the method returns based on this:

if (saveOnExitChoice == SaveSnapshotOnExit::Always &&
    (fc::isEnabled(fc::QuickbootFileBacked) ||
     (!savesWereSlow && !hasLowRam))) {
    return true;
}

Setting QuickbootFileBacked = on in .android/advancedFeatures.ini fixed it for me. See https://androidstudio.googleblog.com/2018/08/android-emulator-28.html.

Answer 2

If you are starting the emulator from the command line. Then provide the -no-snapshot-save parameter, to prevent it from saving.

emulator @Nexus_5X_API_23 -no-snapshot-save

You can configure this setting in Android Studio, see this answer for instructions: Android emulator - Don't save state by default

I do not want to use Android Studio for this. Imagine being on a CI Server and wanting to run emulator tests. – Blowfish
