## Describe the bug

I want to test copying text from the phone and then sending it to my PC through socket, but I found that I can monitor the changes in the clipboard but cannot read the message content.
i just add logs in the addPrimaryClipChangedListener:

```
// Make sure the clipboard manager is always created from the main thread (even if clipboardAutosync is disabled)
ClipboardManager clipboardManager = ServiceManager.getClipboardManager();
if (clipboardAutosync) {
// If control and autosync are enabled, synchronize Android clipboard to the computer automatically
if (clipboardManager != null) {
clipboardManager.addPrimaryClipChangedListener(() -> {
if (isSettingClipboard.get()) {
// This is a notification for the change we are currently applying, ignore it
return;
}
String text = Device.getClipboardText();
Ln.i("clipboard has change");
if (text != null) {
Ln.i("clipboard data is: " + text);
DeviceMessage msg = DeviceMessage.createClipboard(text);
sender.send(msg);
}
});
} else {
Ln.w("No clipboard manager, copy-paste between device and computer will not work");
}
}
```

When I copy text in my phone, the output is as follows:

```
[server] INFO: clipboard has change
[server] INFO: clipboard has change
[server] INFO: clipboard has change
[server] INFO: clipboard has change
[server] INFO: clipboard has change
[server] INFO: clipboard has change
```

the ‘clipboard data is:’ has no output
