When exploring a device's files, the following directories are particularly useful:
data/data/app_name/
Contains data files for your app stored on internal storage
sdcard/
Contains user files stored on external user storage (pictures, etc.)
Note: Not all files on a hardware device are visible in the Device File Explorer. For example, in the data/data/ directory, entries corresponding to apps on the device that are not debuggable cannot be expanded in the Device File Explorer.
On Android Studio 3.1 and above, you can push photos to the emulator, by first starting the emulator. Then select “Device File Explorer” from the menu at the top of the screen: View/Tool Window/Device File Explorer Then look in the folder titled “sdcard” and you will see a folder titled “Pictures”, click on it. Then right click it and select “Upload” and navigate to the photo on your computer, to the photo you would like to push onto the emulator. The restart the emulator.
