    Method m = WebView.class.getMethod("emulateShiftHeld", null);
    m.invoke(this, null);

    // fallback
    KeyEvent shiftPressEvent = new KeyEvent(0,0,
         KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0);

Try below code...

private void emulateShiftHeld(WebView view)
{
    try
    {
        KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
                                                KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
        shiftPressEvent.dispatch(view);
        Toast.makeText(this, "select_text_now", Toast.LENGTH_SHORT).show();
    }
    catch (Exception e)
    {
        Log.e("dd", "Exception in emulateShiftHeld()", e);
    }
}

and Call above method wherever you want...
