    a short summary of above after honeycomb >= API 13:

    public String readFromClipboard() {
        ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        if (clipboard.hasPrimaryClip()) {
            android.content.ClipDescription description = clipboard.getPrimaryClipDescription();
            android.content.ClipData data = clipboard.getPrimaryClip();
            if (data != null && description != null && description.hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN)) 
                return String.valueOf(data.getItemAt(0).getText());
        }
        return null;
    }

    For most Android devices, above Honeycomb Android version 3.0 the below code will work

    For copying text to Clipboard

    ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
            ClipData clip = android.content.ClipData
                        .newPlainText("copyingToClipboard", "your text here to be copied to clipboard");
        clipboard.setPrimaryClip(clip);
    

    For Copying from Clipboard

    ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
            if (clipboard.hasPrimaryClip() && (clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN) || clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_HTML))) {
                ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
                String clipboardtext = item.getText().toString();
                Toast.makeText(Context,clipboardtext,Toast.LENGTH_LONG).show();
            }
    

    The code will avoid null value exception in case the clipboard doesn't contain any data.

    If you just want to "copy and paste" some code into your app, you can use the following.

    #Copy

    String textToCopy = etCodeWindow.getText().toString();
    
    ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
    ClipData clip = ClipData.newPlainText(null, textToCopy);
    if (clipboard == null) return;
    clipboard.setPrimaryClip(clip);
    

    #Paste

    Get the text to paste

    ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
    if (clipboard == null) return;
    ClipData clip = clipboard.getPrimaryClip();
    if (clip == null) return;
    ClipData.Item item = clip.getItemAt(0);
    if (item == null) return;
    CharSequence textToPaste = item.getText();
    if (textToPaste == null) return;
    

    or

    ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
    try {
        CharSequence textToPaste = clipboard.getPrimaryClip().getItemAt(0).getText();
    } catch (Exception e) {
        return;
    }
    

    or the same in Kotlin:

    val clipboard = (getSystemService(Context.CLIPBOARD_SERVICE)) as? ClipboardManager
    val textToPaste = clipboard?.primaryClip?.getItemAt(0)?.text ?: return false
    

    Inserting it at the cursor position

    If there is a selection then the selection will be replaced with the paste text.

    int start = Math.max(myEditText.getSelectionStart(), 0);
    int end = Math.max(myEditText.getSelectionEnd(), 0);
    myEditText.getText().replace(Math.min(start, end), Math.max(start, end),
                textToPaste, 0, textToPaste.length());
    

    #Notes

    • This answer assumes that you are no longer supporting pre-API 11. If you are then see the edit history.
    • Import android.content.ClipboardManager and android.content.ClipData.
    • I used to just get the paste text in a one liner until I discovered that ClipData was giving a NPE crash sometimes. Now I would either use a try/catch block or check more carefully for nulls.

    you can copy and paste text using following code :

    • for copy :

      ClipboardManager clipboard = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
      ClipData clip = ClipData.newPlainText("your_text_to_be_copied");
      clipboard.setPrimaryClip(clip);
      
    • And paste it :

      ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
      String pasteData = "";
      
       // If it does contain data, decide if you can handle the data.
      if (!(clipboard.hasPrimaryClip())) {
      
      } else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) {
      
          // since the clipboard has data but it is not plain text
      
      } else {
      
          //since the clipboard contains plain text.
          ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
      
          // Gets the clipboard as text.
          pasteData = item.getText().toString(); 
      }
