如何使用 android 2.1 sdk 取消配对蓝牙设备

Question

在 Android 2.1 中，要取消配对蓝牙设备，您可以转到蓝牙设置，长按设备并选择取消配对以取消配对该设备。我希望能够从我的应用程序中做到这一点。我可以使用BluetoothAdapter.getBondedDevices() 检索配对/绑定设备的列表，但我找不到如何取消配对。我探索了 BluetoothChat 示例，并搜索了 sdk，但仍然找不到允许这样做的 API。

如何取消配对蓝牙设备？

Answer 1

以下是取消配对/移除绑定设备的方法，调用此方法，其中 macAddress 是设备的 MAC 地址字符串。即"00:02:00:A3:03:05"

IBluetooth ib =getIBluetooth();
ib.removeBond(macAddress);

要获得 IBluetooth 对象，您需要经过几个步骤

1. 在您的项目中创建一个名为 android.bluetooth 的包
2. 创建两个文件，IBluetooth.aidl 和 IBluetoothCallback.aidl

3. 在您的文件中创建名为 getBluetooth() 的方法

   private IBluetooth getIBluetooth() {
   IBluetooth ibt = null;
   
   try {
   
       Class c2 = Class.forName("android.os.ServiceManager");
   
       Method m2 = c2.getDeclaredMethod("getService",String.class);
       IBinder b = (IBinder) m2.invoke(null, "bluetooth");
   
       Class c3 = Class.forName("android.bluetooth.IBluetooth");
   
       Class[] s2 = c3.getDeclaredClasses();
   
       Class c = s2[0];
       Method m = c.getDeclaredMethod("asInterface",IBinder.class);
       m.setAccessible(true);
       ibt = (IBluetooth) m.invoke(null, b);
   
   
   } catch (Exception e) {
       Log.e("flowlab", "Erroraco!!! " + e.getMessage());
   }
   
   return ibt;
   }
   

   /************ IBluetooth.aidl ************/

   package android.bluetooth;
   
   import android.bluetooth.IBluetoothCallback;
   import android.os.ParcelUuid;
   
   /**
     * System private API for talking with the Bluetooth service.
     *
     * {@hide}
     */
    interface IBluetooth
    {
      boolean isEnabled();
      int getBluetoothState();
      boolean enable();
      boolean disable(boolean persistSetting);
   
      String getAddress();
      String getName();
      boolean setName(in String name);
   
      int getScanMode();
      boolean setScanMode(int mode, int duration);
   
      int getDiscoverableTimeout();
      boolean setDiscoverableTimeout(int timeout);
   
      boolean startDiscovery();
      boolean cancelDiscovery();
      boolean isDiscovering();
   
      boolean createBond(in String address);
      boolean cancelBondProcess(in String address);
      boolean removeBond(in String address);
      String[] listBonds();
      int getBondState(in String address);
   
      String getRemoteName(in String address);
      int getRemoteClass(in String address);
      ParcelUuid[] getRemoteUuids(in String address);
      boolean fetchRemoteUuids(in String address, in ParcelUuid uuid, in IBluetoothCallback callback);
      int getRemoteServiceChannel(in String address, in ParcelUuid uuid);
   
      boolean setPin(in String address, in byte[] pin);
      boolean setPasskey(in String address, int passkey);
      boolean setPairingConfirmation(in String address, boolean confirm);
      boolean cancelPairingUserInput(in String address);
   
      boolean setTrust(in String address, in boolean value);
      boolean getTrustState(in String address);
   
      int addRfcommServiceRecord(in String serviceName, in ParcelUuid uuid, int channel, IBinder b);
      void removeServiceRecord(int handle);
   }
   

/************ IBluetoothCallback.aidl ************/

    package android.bluetooth;

    /**
     * System private API for Bluetooth service callbacks.
     *
     * {@hide}
     */
    interface IBluetoothCallback
    {
        void onRfcommChannelFound(int channel);
    }

另一种方式：

public void clear(View v) {
    Set<BluetoothDevice> bondedDevices = adapter.getBondedDevices();
    try {
        Class<?> btDeviceInstance =  Class.forName(BluetoothDevice.class.getCanonicalName());
        Method removeBondMethod = btDeviceInstance.getMethod("removeBond");
        String currentMac = getCurrentMAC();
        boolean cleared = false;
                for (BluetoothDevice bluetoothDevice : bondedDevices) {
            String mac = bluetoothDevice.getAddress();
            if(mac.equals(currentMac)) {
                removeBondMethod.invoke(bluetoothDevice);
                Log.i(TAG,"Cleared Pairing");
                cleared = true;
                break;
            }
        }

                if(!cleared) {
            Log.i(TAG,"Not Paired");
                }
    } catch (Throwable th) {
        Log.e(TAG, "Error pairing", th);
    }
}

Answer 3

您可以将用户发送到蓝牙设置，这样您可以取消配对的设备 意图意图OpenBluetoothSettings = new Intent(); intentOpenBluetoothSettings.setAction(android.provider.Settings.ACTION_BLUETOOTH_SETTINGS); startActivity(intentOpenBluetoothSettings);`

Answer 4

可以通过 droid java 手动取消配对设备。

你可以调用一个隐藏的方法来移除绑定。
