android-adapterservice_btservice.adapterservice need android.permission.b

enable –打开蓝牙

public boolean enable() {

        android.util.SeempLog.record(56);

        if (isEnabled()) {

            if (DBG) Log.d(TAG, "enable(): BT already enabled!");

            return true;

        }

        try {

            return mManagerService.enable(ActivityThread.currentPackageName());

        } catch (RemoteException e) {Log.e(TAG, "", e);}

        return false;

}

1、App通过BluetoothAdapter调用enable接口

2、在BluetoothAdapter 的getDefaultAdapter 中获取BluetoothManagerService服务客户端的代理对象managerService

    IBinder b = ServiceManager.getService(BLUETOOTH_MANAGER_SERVICE);

            if (b != null) {

                IBluetoothManager managerService = IBluetoothManager.Stub.asInterface(b);//获得bind proxy

                sAdapter = new BluetoothAdapter(managerService);

            } else {

                Log.e(TAG, "Bluetooth binder is null");

            }

 

3、通过managerService的regiserAdapter获取AdapterService服务的客户端代理对象mService

private IBluetooth mService;

BluetoothAdapter(IBluetoothManager managerService) {

 

        if (managerService == null) {

            throw new IllegalArgumentException("bluetooth manager service is null");

        }

        try {

            mServiceLock.writeLock().lock();

            mService = managerService.registerAdapter(mManagerCallback);//IBluetooth proxy

        } catch (RemoteException e) {

            Log.e(TAG, "", e);

        } finally {

            mServiceLock.writeLock().unlock();

        }

        mManagerService = managerService;

        mLeScanClients = new HashMap<LeScanCallback, ScanCallback>();

        mToken = new Binder();

    }

 

4、服务连接的时候获取AdapterService的客户端代理对象mBluetooth

 

   private class BluetoothServiceConnection implements ServiceConnection {

        public void onServiceConnected(ComponentName componentName, IBinder service) {

            String name = componentName.getClassName();

            if (DBG) Slog.d(TAG, "BluetoothServiceConnection: " + name);

            Message msg = mHandler.obtainMessage(MESSAGE_BLUETOOTH_SERVICE_CONNECTED);

            if (name.equals("com.android.bluetooth.btservice.AdapterService")) {

                msg.arg1 = SERVICE_IBLUETOOTH;

            } else if (name.equals("com.android.bluetooth.gatt.GattService")) {

                msg.arg1 = SERVICE_IBLUETOOTHGATT;

            } else {

                Slog.e(TAG, "Unknown service connected: " + name);

                return;

            }

            msg.obj = service;

            mHandler.sendMessage(msg);

        }

 

                case MESSAGE_BLUETOOTH_SERVICE_CONNECTED:

                {

                    if (DBG) Slog.d(TAG,"MESSAGE_BLUETOOTH_SERVICE_CONNECTED: " + msg.arg1);

 

                    IBinder service = (IBinder) msg.obj;

              

                        mBluetoothBinder = service;

                        mBluetooth = IBluetooth.Stub.asInterface(Binder.allowBlocking(service));

AdapterService –enable

打开蓝牙之前，先启动并初始化GattService。等GattService启动成功后发送BLE_STARTED消息，

然后在调用enableNative去打开蓝牙。
