The problem of copy and paste

[xxdoc]

Glad to see you've updated the usage of crtl +a. I used crtl +v for replication

i used scrcpy to control my phone

first,i clear the text
adbshellStr = "adb shell am broadcast -a ADB_CLEAR_TEXT" i found this cannot work! donot clear my copyed text in my phone,how does this command mean?
dos send adbshellstr to clear text

then i set something to Clipboard

    Clipboard.Clear
    Clipboard.setText **something** e:xxdoc

the last i set ctrl+v to coyp sometext to phone textbox
adbshellStr = "am broadcast -a ADB_INPUT_TEXT --es mcode '4096,50' "
dos send adbshellstr

===can ADB_CLEAR_TEXT clear this "ctrl+v "get the text?

but i find my phone can not show something e:xxdoc ,but other work i copyed in my phone
