Emulator Window Operations

Dragging a window edge of the emulator window will change the scale used by the emulator. The entire emulator window is still there, just smaller or larger than before. The resulting window will have the proper aspect ratio, so if you drag the left or right side and shrink the window, it will shrink both vertically and horizontally.

Using your development machine’s native file manager (e.g., Nautilus on Ubuntu Linux), you can drag-and-drop files into the emulator window. If the file is an APK, it will be installed automatically. If the file is anything else, it will be uploaded into the emulator’s Download/ directory on external storage. If your app has permission to work with external storage, it can read the file from there.
