Android : Implement Broadcast Receiver for Clipboa

Question

I want to implement a listener which will listen if some copied any thing from any application.

I heard about ClipboardManager.OnPrimaryClipChangedListener() which will listen copy action, but this is not a Receiver (As I understand). I got a sample application, logic behind this application is, start service from system boot and run a service which will listen Copy action, but I think this will drain the battery. Am I right?

So how can I implement a Broadcast receiver which can listen Copy action.

Answer 1

Here is the listener:

class ClipboardListener implements ClipboardManager.OnPrimaryClipChangedListener
{
   public void onPrimaryClipChanged()
   {
      // do something useful here with the clipboard
      // use getText() method
   }
}

Just register it:

ClipboardManager clipBoard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener( new ClipboardListener() );
