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

以下是取消绑定/删除绑定设备的方法，调用此方法，其中macAddress是设备的mac地址字符串.i.e。 “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

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

在文件中创建名为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;
}

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

可以通过droid java手动取消配对设备。

您可以调用隐藏方法来删除绑定。

Answer 4

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