int startIndex = detailedText.getSelectionStart();
int endIndex = detailedText.getSelectionEnd();
Log.d("LOG","startIndex "+ startIndex + "endIndex " + endIndex);///here get index -1 ,-1 for startIndex and endIndex in less than android 4.4 i dont know why?
String YouExtracted = stringYouExtracted.substring(startIndex,endIndex);
int sdk = android.os.Build.VERSION.SDK_INT;
if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(detailedText.getText().toString());
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData
.newPlainText("COPYTEXT", detailedText.getText().toString());
clipboard.setPrimaryClip(clip);

I had the same problem with selecting text in TextView. It's eventuate, because TextView use SpannableString, but static method Selected.getSelectionStart(CharSequence text) return -1 if text not instance of Spanned. I resolve it (and https://code.google.com/p/android/issues/detail?id=191430 for Android 6 ) ovveride dispatchTouchEvent like this:
public class HackyTextView extends TextView {
...
@Override
public boolean dispatchTouchEvent(final MotionEvent event) {
// FIXME simple workaround to https://code.google.com/p/android/issues/detail?id=191430
int startSelection = getSelectionStart();
int endSelection = getSelectionEnd();
if (startSelection < 0 || endSelection < 0){
Selection.setSelection((Spannable) getText(), getText().length());
} else if (startSelection != endSelection) {
if (event.getActionMasked() == MotionEvent.ACTION_DOWN) {
final CharSequence text = getText();
setText(null);
setText(text);
}
}
return super.dispatchTouchEvent(event);
}
}
