KDE Connect Clipboard integration

[xieve]

Is your feature request related to a problem? Please describe. I am a long-time KDE Connect user, which, among other features, can sync clipboards between devices. The Android client has had a major usability regression in this feature beginning with Android 10, since apps are not allowed to monitor the clipboard anymore. One way to work around this is to choose the KDE Connect keyboard in the keyboard picker, however that is mainly intended for remote input and does not provide an actual on-screen keyboard.

Describe the solution you'd like I would like to be able to opt-in into HeliBoard calling KDE Connect's ClipboardFloatingActivity whenever the clipboard is changed, and thus removing the friction from clipboard sync.

I guess it wouldn't be absurd to make the activity that is launched configurable, that way other apps could implement similar functionality in synergy with HeliBoard.

KDE Connect would still need to export the aforementioned activity, but if you'd be willing to implement this, I would open an issue on their GitLab.

I would like to be able to opt-in into HeliBoard calling KDE Connect's ClipboardFloatingActivity whenever the clipboard is changed, and thus removing the friction from clipboard sync.

This should work, though starting an activity seems a bit much. Is there any chance this may interfere with whatever the user is doing? Maybe we could also add the data to an intent instead of starting an activity that reads the clipboard.
