I’m wrapping up a small Android app and the last missing piece is a rock-solid “Copy” action. All text that users select inside the app should be copied to the system clipboard—ready for them to paste elsewhere later, even though my app itself does not handle the pasting step. Here’s the context: • Everything happens inside one Kotlin activity (Java is fine if that’s your preference). • The UI is already in place; I just need the functional code that listens for a long-press or toolbar tap, grabs the highlighted text, and hands it off to ClipboardManager with proper user feedback (toast or snackbar). • Compatibility must cover API 23+. Deliverable: a concise code snippet (or updated class) that drops straight into my existing project, plus a brief note explaining any permissions or imports I may have overlooked. Once I can select text in the running app and see it appear in another app when the user pastes, we’re done.
