Is there an intent “Invalid password when locking the screen”?

You can create your own dialog box in an Android application to display an error message. Below is the code for this:

AlertDialog alertDialog = new AlertDialog.Builder(LoginActivity.this).create();
                        // Setting Dialog Title
                        alertDialog.setTitle("Error");
                        // Setting Dialog Message
                        alertDialog.setMessage("Not A User");
                        // Setting Icon to Dialog
                        alertDialog.setIcon(R.drawable.inputerror);
                        // Setting OK Button
                        alertDialog.setButton("OK",new DialogInterface.OnClickListener() 
                        {
                            public void onClick(DialogInterface dialog, int which) 
                            {
                                // Write your code here to execute after dialog
                                // closed
                                Toast.makeText(getApplicationContext(),"Not A Valid User", Toast.LENGTH_SHORT).show();
                            }
                        });
                        // Showing Alert Message
                        alertDialog.show();
                        return;
