NB: This is kinda pointless in comparison to scrcpy, in particular the HID/OTG mode: https://github.com/Genymobile/scrcpy/blob/master/doc/hid-otg.md
Small script to send keypresses over an ADB shell to any Android phone, e.g. to use your laptop keyboard to compose SMS.
It's not pretty, and the input command this uses has a number of shortcomings:
- Running the command takes ~1s, meaning latency is quite high. Characters are batched to try and lessen this, but you're going to have to be a good touch-typer.
- Non-ASCII characters are not supported. https://stackoverflow.com/questions/14224549/adb-shell-input-unicode-character
There are much more sensible ways of doing this, but they all require switching to a virtual keyboard (and back again when you're done). And I don't speak unicode so that won't annoy me.
The script requires Python 3. Not tested with Python 2, but might work.
Enable ADB on your phone and connect. Run adb-keyboard and start typing. Ctrl-C to finish.
There are some special key combinations listed at the top of the script.
