Can I disable Bluetooth or camera or wifi of android device and allow enabling only through my customized app?

Below is the code for enabling/disabling but it does not disable the device settings.

I want to know how to disable bluetooth(Camera/Wifi) facility of android device and enable it only through my customized app. User should be able to on the bluetooth only through our app.

BluetoothAdapter bluetoothAdapter = BluetoothAdapter
            .getDefaultAdapter();
    boolean isEnabled = bluetoothAdapter.isEnabled();
    if (isEnabled) {
        Toast.makeText(getApplicationContext(), "Enabled",
                Toast.LENGTH_SHORT).show();
        bluetoothAdapter.disable();
    } else {
        Toast.makeText(getApplicationContext(), "Not Enabled",
                Toast.LENGTH_SHORT).show();
        bluetoothAdapter.enable();
    }

You need to implement BroadcastReceiver that listens to BluetoothAdapter.ACTION_STATE_CHANGED (link). It should disable it back and show some information about your lock to user.

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();

        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
            final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE,
                                                 BluetoothAdapter.ERROR);
            switch (state) {
            case BluetoothAdapter.STATE_OFF:
                //do nothing
                break;
            case BluetoothAdapter.STATE_TURNING_OFF:
                //do nothing
                break;
            case BluetoothAdapter.STATE_ON:
                //disable it
                break;
            case BluetoothAdapter.STATE_TURNING_ON:
                //do nothing
                break;
            }
        }
    }
};

This is a bit hacky, but this is the best you can do - like I wrote previously there is no way to disable this switch in Settings, as Settings are separate application and you cannot modify it, just like other apps cannot modify your application.
