it helps some times 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.

code :

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;
            }
        }
    }
};

Android disable/enable Wifi and Bluetooth permanently

wish help you to fix your issue Just 5 minutes more got me the on the right track...
the problem with my approach above is, that i wait listen to turning off / on. It seems that if i disable the bluetooth while it is just turning on, it will just continue to turn on and stay on. So i have to wait until it is actually turned on and then disable it. In other words, i had to remove 8 characters and it works fine:

code :

public void onReceive(final Context context, final Intent intent) {
    // get new wifi state
    final int bluetoothState = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.STATE_ON);
    final BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

    // if enabling, check if thats okay
    if (bluetoothState == BluetoothAdapter.STATE_ON && BT_FORCE_DISABLE) {
        mBluetoothAdapter.disable();
    } else

    // if disabling, check if thats okay
    if (bluetoothState == BluetoothAdapter.STATE_OFF && BT_FORCE_ENABLE) {
        mBluetoothAdapter.enable();
    }
}

this one helps. you can turn ON/OFF wifi,bluetooth,reduce display brightness-volume but you can't directly to for mobile data and gps. for those things you need to Manually push an intent. bluetooth,WiFi ,brightness,Volume, GPS ,mobile-data
