Android clipboard details

I won't say much about what the clipboard is. Here we will only talk about the simplest application and paste general text.

Some time ago, I was busy learning things and doing things. In the past few days, my pony spent some time learning official documents. There were too many good things in it. Today I saw clip, but I don't understand it anyway, pony made a demo with shameless curiosity. Let's first note that when using the android clipboard, you only need to remember one thing, whether it's Android or PC, copy and paste can only be used on one object at a time. The general point is: on a PC, it is impossible to copy data from disk C at the same time, and copy data from disk D. For details, refer to the code, the code is very simple:
