在Android 2.1中,要取消配对蓝牙设备,您可以进入蓝牙设置,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()获取配对/绑定设备列表,但我找不到如何取消配对的方法。我已经探索了BluetoothChat示例,并搜索了sdk,但仍然找不到允许此操作的API。
如何取消配对蓝牙设备?
如何取消配对蓝牙设备?
以下是如何取消配对/移除已绑定设备的方法,调用此方法时,其中macAddress为设备的MAC地址字符串,例如:"00:02:00:A3:03:05"
IBluetooth ib =getIBluetooth();
ib.removeBond(macAddress);
要获取IBluetooth对象,您需要经过几个步骤
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;
/**

*
* {@hide}
*/
interface IBluetooth
{
boolean isEnabled();
int getBluetoothState();
boolean enable();
boolean disable(boolean persistSetting);
String getAddress();
String getName();
boolean setName(in String name);

boolean removeBond(in String address);

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);
}
另一种方法:
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);
}
}
您可以通过此方法将用户发送到蓝牙设置页面,从而可以取消配对已配对的设备。 Intent intentOpenBluetoothSettings = new Intent(); intentOpenBluetoothSettings.setAction(android.provider.Settings.ACTION_BLUETOOTH_SETTINGS); startActivity(intentOpenBluetoothSettings);
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绑定。
