Is there a way to remove the clipboard content？

How to do it

[majido]

Cannot you do this by setting an empty string? e.g. am broadcast -a clipper.set -e text ""

[unstablereality]

I think you need to send a space, which may or may not require escaping.

am broadcast -a clipper.set -e text " " or am broadcast -a clipper.set -e text "\ "
