Android蓝牙配对

article/2025/10/8 10:36:23

上一篇博客介绍了Android ble的一些情况。

蓝牙如果链接好，能够读写，基本上完成了。蓝牙还有个比较烦人的东西，就是蓝牙配对。

Android ble4.0使用的配对方式和原先版本的配对方式不一样。


看了网上很多地方都是hellogv大神的方法，这个真心不错。

http://blog.csdn.net/hellogv/article/details/6042091


本着认真的态度，我把Android系统中Settings的源码给研究了下，发现了配对的流程，Settings的源码大小大概有300m，考虑的攻击

Ble4.0的配对界面有2个部分，首先的是一个请求的配对的通知，点击了是一个确认对话框，再点击，然后又有个通知，点击通知后，有个输入密码的的对话框，输入密码后，点确定，稍后就会有配对的结果。


下面是Settings中的源码

Settings的目录是/package/app/Settings，下面是Setting的源码url，感兴趣的同学可以去研究下

http://git.omapzoom.org/   所有的源码网址

http://git.omapzoom.org/?p=platform/packages/apps/Settings.git;a=summary  Settings的网址

git://git.omapzoom.org/platform/packages/apps/Settings.git Settings的git地址

 

Settings中的蓝牙代码都在/Settings/src/com/android/settings/bluetooth目录中

主要流程看下面的文件

/Settings/src/com/android/settings/bluetooth/BluetoothPairingDialog.java

代码中很多的类，在实际的Android应该开发中是没有的，我这边准备了三个jar文件，分别是framework.jar,core.jar,ext.jar，这些事Android系统编译的时候，生产的jar。

导入到elcipse中，关联此jar就可以。关联的jar时放在libs中，但是有个必须注意的地方，点击项目的属性，在Java BuildPath类别，Order and Export标签，Android Dependenceis必须要比Android 5.0的在上面，这样在引用的时候，就会优先引用Android Dependceis中的jar。






下面是Setting中的BluetoothPairingDialog.java，简单分析下，中文部分是我添加的注释。

{mPairingView.setInputType(InputType.TYPE_CLASS_TEXT);} else {mPairingView.setInputType(InputType.TYPE_CLASS_NUMBER);}}
}

1、对话框的创建

当收到请求配对的广播后，此对话框会显示。

	protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);// 必须是ACTION_PAIRING_REQUEST，否则不运行,ACTION_PAIRING_REQUEST是一个请求的配对的广播Intent intent = getIntent();if (!intent.getAction().equals(BluetoothDevice.ACTION_PAIRING_REQUEST是一个请求的配对的广播)) {Log.e(TAG, "Error: this activity may be started only with intent " + BluetoothDevice.ACTION_PAIRING_REQUEST);finish();return;}LocalBluetoothManager manager = LocalBluetoothManager.getInstance(this);if (manager == null) {Log.e(TAG, "Error: BluetoothAdapter not supported by system");finish();return;}CachedBluetoothDeviceManager deviceManager = manager.getCachedDeviceManager();// 获取配对的设备和配对类型，我的项目中配对类型是BluetoothDevice.PAIRING_VARIANT_PINmDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);mType = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT, BluetoothDevice.ERROR);// 根据配对的类型，进行分发,我们重点关注PAIRING_VARIANT_PINswitch (mType) {case BluetoothDevice.PAIRING_VARIANT_PIN:case BluetoothDevice.PAIRING_VARIANT_PASSKEY:// 创建用户输入配对密码的对话框createUserEntryDialog(deviceManager);break;case BluetoothDevice.PAIRING_VARIANT_PASSKEY_CONFIRMATION:int passkey = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_KEY, BluetoothDevice.ERROR);if (passkey == BluetoothDevice.ERROR) {Log.e(TAG, "Invalid Confirmation Passkey received, not showing any dialog");return;}mPairingKey = String.format(Locale.US, "%06d", passkey);createConfirmationDialog(deviceManager);break;case BluetoothDevice.PAIRING_VARIANT_CONSENT:case BluetoothDevice.PAIRING_VARIANT_OOB_CONSENT:createConsentDialog(deviceManager);break;case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY:case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PIN:int pairingKey = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_KEY, BluetoothDevice.ERROR);if (pairingKey == BluetoothDevice.ERROR) {Log.e(TAG, "Invalid Confirmation Passkey or PIN received, not showing any dialog");return;}if (mType == BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY) {mPairingKey = String.format("%06d", pairingKey);} else {mPairingKey = String.format("%04d", pairingKey);}createDisplayPasskeyOrPinDialog(deviceManager);break;default:Log.e(TAG, "Incorrect pairing type received, not showing any dialog");}/** Leave this registered through pause/resume since we still want to* finish the activity in the background if pairing is canceled.*/// 注册广播registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_PAIRING_CANCEL));registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED));}


2、创建有输入框的界面

	// 创建用户输入配对密码的对话框private void createUserEntryDialog(CachedBluetoothDeviceManager deviceManager) {// 创建对话框的界面，// 在看看对话框的确定的回调函数，由于本类是实现DialogInterface.OnClickListener的方法的，我们可以去看下// public void onClick(DialogInterface dialog, int which)final AlertController.AlertParams p = mAlertParams;p.mIconId = android.R.drawable.ic_dialog_info;p.mTitle = getString(R.string.bluetooth_pairing_request);p.mView = createPinEntryView(deviceManager.getName(mDevice));p.mPositiveButtonText = getString(android.R.string.ok);p.mPositiveButtonListener = this;p.mNegativeButtonText = getString(android.R.string.cancel);p.mNegativeButtonListener = this;setupAlert();mOkButton = mAlert.getButton(BUTTON_POSITIVE);mOkButton.setEnabled(false);}


3、查看输入框的确定回调函数

	// 对话框的确定的回调public void onClick(DialogInterface dialog, int which) {switch (which) {case BUTTON_POSITIVE:// 进行配对if (mPairingView != null) {onPair(mPairingView.getText().toString());} else {onPair(null);}break;case BUTTON_NEGATIVE:default:onCancel();break;}}

4、配对 

	// 进行配对private void onPair(String value) {// 根据类型进行分发switch (mType) {case BluetoothDevice.PAIRING_VARIANT_PIN:// 注意这里是用了转换的方法，不是直接调用value.getBytes();方法byte[] pinBytes = BluetoothDevice.convertPinToBytes(value);if (pinBytes == null) {return;}// 直接调用setPin方法,然后就没有了，等到收到状态改变的广播后就进行dismiss,请看54行的mReceivermDevice.setPin(pinBytes);break;case BluetoothDevice.PAIRING_VARIANT_PASSKEY:int passkey = Integer.parseInt(value);mDevice.setPasskey(passkey);break;case BluetoothDevice.PAIRING_VARIANT_PASSKEY_CONFIRMATION:case BluetoothDevice.PAIRING_VARIANT_CONSENT:mDevice.setPairingConfirmation(true);break;case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY:case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PIN:// Do nothing.break;case BluetoothDevice.PAIRING_VARIANT_OOB_CONSENT:mDevice.setRemoteOutOfBandData();break;default:Log.e(TAG, "Incorrect pairing type received");}}

// 注意这里是用了转换的方法，不是直接调用value.getBytes();方法
byte[] pinBytes = BluetoothDevice.convertPinToBytes(value);

下面是系统的中的配对密码转换

    /*** Check that a pin is valid and convert to byte array.** Bluetooth pin's are 1 to 16 bytes of UTF-8 characters.* @param pin pin as java String* @return the pin code as a UTF-8 byte array, or null if it is an invalid*         Bluetooth pin.* @hide*/public static byte[] convertPinToBytes(String pin) {if (pin == null) {return null;}byte[] pinBytes;try {pinBytes = pin.getBytes("UTF-8");} catch (UnsupportedEncodingException uee) {Log.e(TAG, "UTF-8 not supported?!?");  // this should not happenreturn null;}if (pinBytes.length <= 0 || pinBytes.length > 16) {return null;}return pinBytes;}



5、根据配对的结果，进行配对 

	private final BroadcastReceiver mReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {// 当设备的配对状态改变的时候，就把对话框去掉int bondState = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, BluetoothDevice.ERROR);if (bondState == BluetoothDevice.BOND_BONDED || bondState == BluetoothDevice.BOND_NONE) {dismiss();}} else if (BluetoothDevice.ACTION_PAIRING_CANCEL.equals(action)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);if (device == null || device.equals(mDevice)) {dismiss();}}}};

以上就是系统的设置的配对流程。




下面是自己的项目中的业务代码

	BroadcastReceiver bleReceiver = new BroadcastReceiver() {public void onReceive(Context context, Intent intent) {McLog.mByStackTrace();String action = intent.getAction();McLog.i("action = " + action);if (BluetoothDevice.ACTION_FOUND.equals(action)) {// 搜索设备doDeviceSearch(intent);} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) { //搜索结束doDeviceSearchFinished(intent);} else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) { // 设备状态改变doStateChange(intent);} else if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)) {// 请求匹配doRequestPari(intent);}}void doStateChange(Intent intent) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);switch (device.getBondState()) {case BluetoothDevice.BOND_NONE:McLog.i("取消配对");break;case BluetoothDevice.BOND_BONDING:McLog.i("正在配对......");break;case BluetoothDevice.BOND_BONDED:McLog.i("完成配对");break;}}void doDeviceSearch(Intent intent) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);McLog.i("device = " + device);if (device.getBondState() == BluetoothDevice.BOND_BONDED) {// 已经配对的则跳过} else {if (!searchDevices.contains(searchDevices)) {searchDevices.add(device);}}}void doDeviceSearchFinished(Intent intent) {McLog.i("search finished, searchDevices's size = " + searchDevices.size());boolean isFindRightDevice = false;for (BluetoothDevice device : searchDevices) {if (isRightDevice(device)) { //  如果是我想要的设备，那么我就进行配对doNormalPair(device);isFindRightDevice = true;break;}}if (!isFindRightDevice) {McLog.i("sorry,do't search user's device[" + bleDeviceMac + "]");}}void doNormalPair(BluetoothDevice device) {McLog.mByStackTrace();currentPairDevice = device;try {// 调用配对的方法，此方法是异步的，系统会触发BluetoothDevice.ACTION_PAIRING_REQUEST的广播// 收到此广播后，设置配对的密码ClsUtils.createBond(BluetoothDevice.class, currentPairDevice);} catch (Exception e) {e.printStackTrace();}}void doRequestPari(Intent intent) {BluetoothDevice btDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);if (btDevice.getBondState() == BluetoothDevice.BOND_BONDED) {McLog.e("已经绑定");} else {McLog.e("没有绑定");if (currentPairDevice != null && btDevice.getAddress().equalsIgnoreCase(currentPairDevice.getAddress())) {try {McLog.i("invoke setpin :" + bleDeviceMac);// 设置配对的密码 <span style="font-family: Arial, Helvetica, sans-serif;">bleDevicePasswd 设备的配对密码</span>ClsUtils.setPin2(BluetoothDevice.class, currentPairDevice, bleDevicePasswd);} catch (Exception e) {McLog.i("e = " + e);}currentPairDevice = null;uiHandler.postDelayed(new Runnable() {public void run() {loadBleData();// 注销监听unregisterReceiver(bleReceiver);}}, 1000);}}}};




以上就能完成ble4.0的密码自动配对，当然中间的对话框会显示1s左右时间，然后会再次消失。
