如何在Android 2.1中取消配对蓝牙设备sdk

Question

在Android 2.1中，要取消配对蓝牙设备，您可以转至蓝牙设置，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执行此操作。我可以使用BluetoothAdapter.getBondedDevices()检索配对/绑定设备的列表，但我找不到如何配对。我已经探索了BluetoothChat示例，并且我已经搜索了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

可以通过droid java手动取消配对设备。

您可以调用隐藏的方法来删除键。

Answer 2

下面介绍如何取消配对/删除绑定设备时调用此方法，其中macAddress是设备的mac地址字符串..i.e。 “00：02：00：A3：03：05”

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

要获得IBluetooth对象，你需要经过几个步骤

1. 在您的项目称为android.bluetooth创建一个包
2. 创建两个文件，IBluetooth.aidl和IBluetoothCallback.aidl

3. 创建文件）方法调用getBluetooth（

   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; 
   }

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); 
    } 
}
