[android] How to copy text programmatically in my Android app?

Android support library update

As of Android Oreo, the support library only goes down to API 14. Most newer apps probably also have a min API of 14, and thus don't need to worry about the issues with API 11 mentioned in some of the other answers. A lot of the code can be cleaned up. (But see my edit history if you are still supporting lower versions.)

Copy

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText("label", selectedText);
if (clipboard == null || clip == null) return;
clipboard.setPrimaryClip(clip);

Paste

I'm adding this code as a bonus, because copy/paste is usually done in pairs.

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

Notes

  • Be sure to import the android.content.ClipboardManager version rather than the old android.text.ClipboardManager. Same for ClipData.
  • If you aren't in an activity you can get the service with context.getSystemService().
  • I used a try/catch block for getting the paste text because multiple things can be null. You can check each one if you find that way more readable.
