是否可以从使用Intent过滤器和广播的类中创建多个实例?

如何解决是否可以从使用Intent过滤器和广播的类中创建多个实例?

我正在尝试扩展用于连接到单个BLE设备的解决方案。为此,我创建了2个类的多个实例,这些实例大量使用广播来耦合其执行顺序。

我有3个名为DeviceSequenceBluetooth的类。

SequenceBluetooth是使用广播和过滤器意图的。对于每个BLE设备,将从DeviceSequenceBluetooth创建3个新实例。

我在SequenceBluetooth中看到奇怪的行为,所以我想确认是否需要为Sequence和{{1}中创建的每个实例使用唯一的意图过滤器}?

构造类时是否可以动态更改意图过滤器?

我非常感谢您的帮助

Bluetooth

我在下面的类中运行我的操作序列:

public class Bluetooth {
   private final static String TAG = BluetoothBle.class.getSimpleName();
   private Context mContext;// I am using the Applicationcontext
   private Boolean mDisconnectScheduledFlag = false;//in case we issue disconnect while timer is working

   //Run send data in thread
   private HandlerThread mHandlerThread;
   private Handler mHandler;
   private  int mIntervalBetweenTwoPackag =100;
   private Boolean mDisconnectedFlag = false;

   private BluetoothManager mBluetoothManager;
   private BluetoothAdapter mBluetoothAdapter;
   private String mBluetoothDeviceAddress;
   private BluetoothGatt mBluetoothGatt;
   private int mConnectionState = STATE_DISCONNECTED;

   private static final int STATE_DISCONNECTED = 0;
   private static final int STATE_CONNECTING = 1;
   private static final int STATE_CONNECTED = 2;

//Intent Filters - Do i need to change . create them dynamically for every created instance of the class
   private static final  String ACTION_GATT_CONNECTED =
           "com.hworld.bluetooth.le.ACTION_GATT_CONNECTED";
   private static final  String ACTION_GATT_DISCONNECTED =
           "com.world.bluetooth.le.ACTION_GATT_DISCONNECTED";
   private static final  String ACTION_GATT_SERVICES_DISCOVERED =
           "com.world.bluetooth.le.ACTION_GATT_SERVICES_DISCOVERED";
   private static final  String ACTION_DATA_AVAILABLE =
           "com.world.bluetooth.le.ACTION_DATA_AVAILABLE";
   private static final  String EXTRA_DATA =
           "com.world.bluetooth.le.EXTRA_DATA";

   // Implements callback methods for GATT events that the app cares about.  For example,// connection change and services discovered.

               Log.i(TAG,"Attempting to start com.wakeup.bluetoothtest.service discovery:" +
                       mBluetoothGatt.discoverServices());
