检测手动蓝牙禁用

Question

我的Android应用程序必须捕获MANUAL禁用蓝牙以避免欺诈。我使用以下代码，一些用户告诉我，任何蓝牙错误都会触发btTurnedOff()。

...监听

public interface BtConnectionListener {

    void btTurnedOff();
}

...接收器

public class BtConnectionReceiver extends BroadcastReceiver {

private final BtConnectionListener listener;

public BtConnectionReceiver(final BtConnectionListener listener) {
    this.listener = listener;
}

@Override
public void onReceive(final Context context, final Intent intent) {
    final String action = intent.getAction();
    if (action != null && action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
        final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.ERROR);
        switch (state) {
            case BluetoothAdapter.STATE_TURNING_OFF:
                listener.btTurnedOff();
                break;
            }
        }
    }
}

在我的主要服务中......

@Override
public void btTurnedOff() {
    //Some stuff to penalize the fraud
}

任何人都知道我做错了什么？
