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执行此操作.我可以使用BluetoothAdapter.getBondedDevices()检索配对/绑定设备列表,但我找不到如何取消配对.我已经探索了BluetoothChat示例,我搜索了sdk,但仍然无法找到允许这样做的API.

如何取消配对蓝牙设备？

Answer 1

以下是取消绑定/删除绑定设备的方法,调用此方法,其中macAddress是设备mac地址的字符串."00:02:00:A3:03:05"

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

要获得IBluetooth对象,您需要完成几个步骤

1. 在你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. 在你的文件中创建名为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);
    }

可以通过 droid java 手动取消设备配对。

您可以调用隐藏方法来删除键。
