I have made a customized text editor view extending directly from “android.view.View”. Everything works fine except Samsung clipboard (which supports multiple copy and paste) in Samsung input method. The Android system clipboard works well, but Samsung clipboard is grayed and disabled. Is there any documentation for how to support Samsung clipboard and activate this feature in my customized view? I believe there are some logic in android.sec.clipboard.ClipboardExManager for this support but it is not open source. Thanks.
