Looks like a really good extension Joe, but the method ClearClipboard used to clear the clipboard will mean that it's never empty. ClearClipboardCompletely sounds better, I will try it.

Is it limited to specific Android versions?

Tested and working, Android 10, single string. (APK)

Yes, I was procrastinating for a few days because I couldn't completely delete the clipboard. I think there must be some way to do it, but I couldn't find it, I think you can do it.

I haven't tried it on other devices, but it should work on all of them, tested on Android 11.

Really crazy that Google have left an often used facility insecure.

As it is going, everything is restricting, it won't be long before it does. He is going to make it more difficult for us every time.

But we will find a way.

Hi, can the clipboardContentChanged block still monitor the clipboard when my app is in the background - ie, is not the current app which might be making changes to the clipboard?
Thanks,
C.

Most probably not

This is what Gemini thinks:

Creating a clipboard monitor for Target SDK 35 (Android 15) is a significant technical challenge because of strict privacy changes introduced by Google.

​Starting with Android 10, apps are strictly forbidden from reading the clipboard while in the background unless they are the "Default Input Method" (the keyboard). On Android 14 and 15, even if you have a Foreground Service, the system will show a visible notification or block access if the app does not have focus.

​However, you can achieve this if the user manually grants a "Special Permission" via ADB or if you use a Foreground Service to keep the listener alive.

  1. The App is in the Foreground: It will work perfectly as long as the user is looking at the app.
  2. ​The App is in the Background: The event will not fire by default. To bypass this, your users must run an ADB command on their phone to grant the hidden permission:

​adb shell appops set your.package.name READ_CLIPBOARD allow
