How to Cold Boot Emulators Running API 27+ on Android Studio?

Question

While working with emulators in Android Studio, I prefer to have them always cold-boot because:

1) I like it when the emulator window closes immediately after clicking "X-close" rather than beginning a new "saving state" procedure.

2) I find that many-a-bugaboo occurs when returning to a "saved state" with these emulators (connection timeout on bootup, weird graphics behavior, loss of logcat connection, garbled data retrieved from shared prefs)

So... what I have always done is to go into AVD manager and change the settings like this:

However, when I attempt this with an emulator running API 27 or higher:

...there appears to be no cold boot option:

I have googled to try to find how to configure cold boot on these newer API emulators but can't find anything.

Is it possible to cold boot emulators running API 27+ on Android Studio?

Do you have an option of Cold Boot Now in AVD manager when you click on an arrow next to the settings button? – Egyptian

Nope. Android Studio 3.1.2 on mac. – Spoil

I have a Mac too, I'll see if I have it – Egyptian

Can't you shut down your AVD when you're done with it? When you need to use it again, it will cold boot. – Lanchow

Wanted to get back to you because I finally checked with Android Studio 3.1 having the same emulator that you mentioned API 27. It's true there is no Cold Boot in Settings, but in the AVD manager, where all Emulators are listed, if I click on the arrow button which is next to the settings (pencil button) I have an option of Cold Boot Now. – Egyptian

Thanks for getting back. That's wierd, mine just starts without asking me anything. – Spoil

And when you click on the arrow which options do you have? – Egyptian

None, it just starts the emulator without asking anything. :S – Spoil

Oh crap I'm sorry I realized you meant the down arrow... not "play" arrow. DERP! Thanks! – Spoil

no problem :) glad I could help :) good luck! – Egyptian

Answer 1

Change config in:

%path_to_home%/.android/avd/%your_avd_image%/config.ini

Instead of

fastboot.forceColdBoot=no

you should set

fastboot.forceColdBoot=yes

Subset

Adding to Max's Solution,path of config.ini is changed.Please find below path where we can find config file. C:\Users**YourName**\.android\avd\"Select your AVD" After going to above path, we can see config.ini file.Right click and open with notepad++ and search for below parameter and change it to yes. fastboot.forceColdBoot=yes – Pteridophyte

Answer 2

You can find the option if you show advance settings and scroll down. It is in the section: "Emulated Performance"
