Rotate Android Emulator In Espresso Test

Question

I can currently rotate the display for my application from my espresso test by doing:

val currentActivity = getCurrentActivity()
currentActivity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
getInstrumentation().waitForIdleSync()

However, this will only rotate the display; the emulator itself remains in portrait mode. I have the auto-rotate setting turned to on / rotate contents of the screen.

Does anyone know how to get the emulator to also rotate?

Answer 1

You can rotate the display using emulator commands over telnet.

From the docs:

$ telnet localhost 5554
...
auth 123456789ABCdefZ
...
rotate
...

(on macOS, you might need to brew install telnet)
