Toast Message is not displayed?

Question

I am trying to give an application, Bluetooth connectivity when the Bluetooth is turned on it does not show the toast message

if (!bluetoothAdapter.isEnabled()) {

                    Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

                    startActivityForResult(intent, 1);
                    Toast.makeText(HeartRate.this, "Turned on", Toast.LENGTH_LONG);
                }

Answer 1

you forgot something

 if (!bluetoothAdapter.isEnabled()) {

                Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

                startActivityForResult(intent, 1);
//.show happens a lot of times to me
                Toast.makeText(HeartRate.this, "Turned on", Toast.LENGTH_LONG).show();
            }
