几天前,我在Google Play商店下载了Bluetooth Smart Scanner软件.在我的三星Galaxy S3手机上安装后,我可以成功扫描我的蓝牙LE设备.

尽管我已经尝试过扫描我的蓝牙LE设备的所有方法,但我的计算机上没有显示任何内容.所以我反编译了这个软件,startLeDiscovery()包中有一个方法android.bluetooth.但令我困惑的是,这个方法在我android.jar的android sdk 15中不存在.

最后,我用Bluetooth Smart Scanner软件替换了它们的BlutoothAdapter.class文件和BluetoothDevice.class文件android.jar,这样我就可以startLeDiscovery()在Eclipse中成功调用该方法.源代码如下图所示.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    IntentFilter intent = new IntentFilter();
    intent.addAction(BluetoothDevice.ACTION_FOUND);
    intent.addAction(BluetoothDevice.EXTRA_UUID);
    intent.addAction(BluetoothDevice.ACTION_GATT_PRIMARY_UUID);

    registerReceiver(searchDevices, intent);
    //bluetooth.discovery();      
    bluetooth.startLeDiscovery();

  }  
    private BroadcastReceiver searchDevices = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        BluetoothDevice device = null;

        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
            device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);   
            String msg = device.getName()+"\n"+device.getAddress();
            Log.i("hella",msg);
            bluetooth.cancelDiscovery();
            connectDevice(device); …
