Unable to start activity ComponentInfo,I have no idea

Question

I am having this error in this code:

Unable to start activity UomponentInfo {com.example.ilovemii.myapplicationblue/com.example.ilovemii.myapplicationblue.hotlifebluetoothspp}: android.util.AndroidRuntimeException: You cannot combine custom titles with other title features

at com.example.ilovemii.myapplicationblue.hotlifebluetoothspp.onCreate(hotlifebluetoothspp.java:81)

my hotlifebluetoothspp.java code

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(D) Log.e(TAG, "+++ ON CREATE +++");

        // Set up the window layout
        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.hotlife_bluset);

        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);

        // Set up the custom title
        mTitle = (TextView) findViewById(R.id.title_left_text);
        mTitle.setText(R.string.app_name);
        mTitle = (TextView) findViewById(R.id.title_right_text);
        // Get local Bluetooth adapter

        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        mOutEditText = (EditText) findViewById(R.id.edit01);
        mOutEditText.setInputType(InputType.TYPE_NULL);
        SharedPreferences settings = getSharedPreferences(SETTING_PREF, 0);
        String msg1 = settings.getString(SHARED_send, "");
        if(msg1 == null){
            mOutEditText.setText("R");
        }else{
            mOutEditText.setText(msg1);
        }
        // If the adapter is null, then Bluetooth is not supported
        if (mBluetoothAdapter == null) {
            Toast.makeText(this, "Bluetooth is not available", Toast.LENGTH_LONG).show();
            finish();
            return;
        }
    }

this is my AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
