Android Emulator Snapshot file location
Press for 3 dots. Then Press the Settings and in top right corner you will see the screenshot folder location.
To retrieve the saved snapshot on disc, you have to go to the AVD location. In Android Virtual Device Manager, right click on your AVD, then show on disc. You will find a directory call snapshots
There's now a setting for this in the Emulator itself. In the options menu, tap on the Three Dots button to open Extended Controls. Tap the 'Settings' item in the left-hand list and you'll see 'Screenshot save location', which is an editable field.
