Android蓝牙SDP无法识别JAVAME中宣传的服务

Question

我正在Bluetooth为我的MSc 开发一个应用程序.结束项目.它包括一个实现的服务器JAVA ME和一个写入的客户端Android.

问题是Android SDP似乎无法识别ServiceRecord我的JAVA ME服务器.

如果我使用这些方法BluetoothDevice.getUuids()并BluetoothDevice.fetchUuidsWithSdp()在我的客户端中,它们返回一组UUIDs,但我的服务UUID在其中没有,因此我无法连接到它.

这是JAVAME服务器示例的代码 :

/*IMPORTS*/

public class StackOverFlowServer extends MIDlet {
    Display mDisplay;
    Form mForm;
    LocalDevice local;
    StreamConnectionNotifier server;
    ServiceRecord sr;
    String conURL;
    StreamConnection conn;
    public StackOverFlowServer() {
        mDisplay = Display.getDisplay(this);
        mDisplay.setCurrent(mForm);
        mForm = new Form(null);
        conURL = "btspp://localhost:68EE141812D211D78EED00B0D03D76EC;"
                + "authenticate=false;encrypt=false;name=MySampleApp";
    }

    protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
        // TODO Auto-generated method stub

    }

    protected void pauseApp() {
        // TODO Auto-generated method stub

    }

    protected void startApp() throws MIDletStateChangeException {
        try {
            local = LocalDevice.getLocalDevice();
        } catch (BluetoothStateException e) {
            // Error handling code here
        }
        /*
        * When creating a StreamConnectionNotifier a service record
        * will automatically be created for us, describing the new
        * service. The service will have the Serial Port (0x1101)
        * value in the ServiceClassIDList (id 0x0001) attribute. The
        * service record will also have both the L2CAP (0x0100) and
        * RFCOMM (0x0003) values in the ProtocolDescriptorList (id

        * ServiceName (id 0x100) attribute will be set to the name
        * parameter, "BTDemoApp" in this case.
        */
        try {
            server = (StreamConnectionNotifier)
                    Connector.open(conURL);
        } catch (IOException e1) {
            // Error handling code here
        }
        /*
        * The automatically created service record can be obtained
        * from the LocalDevice object, using the reference to the
        * StreamConnectionNotifier.
        */
        try {
            sr = local.getRecord(server);
        }
        catch (IllegalArgumentException iae){
            // Error handling code here
        }
        /*
        * We create a new DataElement and set its content correctly.
        */
        DataElement elm = null;
        /*
        * Setting public browse root in the browsegrouplist
        * attribute. The BrowseGroupList (id 0x0005) attribute

        */
        elm = new DataElement(DataElement.DATSEQ);
        elm.addElement(new DataElement(
        DataElement.UUID,new UUID(0x1002)));
        /*
        * The DataElement is now prepared. It must be added to the
        * appropriate attribute ID, in this case the
        * BrowseGroupList.
        */
        sr.setAttributeValue(0x0005,elm);
        /*
        * Finally, the service record must be updated in our
        * LocalDevice.
        */
        try {
            local.updateRecord(sr);
        } catch (ServiceRegistrationException e3) {
            // Error handling code here
        }
        try {
        conn = server.acceptAndOpen();
        } catch (ServiceRegistrationException sre){
            // Error handling code here
        } catch (IOException e2) {
            // Error handling code here
        }
        /*
        * At this point a client is connected. input and output
        * streams can be obtained from the conn object,
        * communication can begin.
        */
    }
}

这是Android客户端的一部分:

package com.exampleproyect.stackoverflowclient;

import java.lang.reflect.InvocationTargetException;
import java.util.UUID;

import android.app.Activity;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.ParcelUuid;
import android.os.Parcelable;

public class StackOverFlowClientActivity extends Activity {
    BluetoothAdapter mBluetoothAdapter;
    BluetoothDevice C702;
    BroadcastReceiver mReceiver;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        C702 = mBluetoothAdapter.getRemoteDevice("00:23:F1:27:16:DA");
        C702.fetchUuidsWithSdp();
        mReceiver = new BroadcastReceiver() {
          @Override
          public void onReceive(Context arg0, Intent intent) {
              String action = intent.getAction();
              if (BluetoothDevice.ACTION_UUID.equals(action)){
                  Parcelable[] uuidExtra =                    intent.getParcelableArrayExtra("android.bluetooth.device.extra.UUID");
                  /*uuidExtra should contain my service's UUID among his files, but it doesn't!!*/
              }
          }
      };
      // Register the BroadcastReceiver
      IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_UUID);
      registerReceiver(mReceiver, filter1); // Don't forget to unregister during onDestroy
    }
}

最困扰我的是,我的电脑可以JAVAME正确地看到我的服务器广告:

我究竟做错了什么？？:(为什么我的电脑Bluetooth看我的服务在正确传播JAVAME而Android不能??可以Android通过连接Bluetooth到JAVAME服务器？

我在StackOverFlow中已经阅读了大量其他类似的问题,但我还没有找到一个可行的解决方案.:(

我正在使用索尼爱立信C702(Java平台8)作为测试服务器.和三星Galaxy S(ICS 4.0.3,团队ICSSGS RC4.2)

好.

我知道问题是什么.

我希望JAVAME服务器用UUID(例如)宣传我的服务:"68EE1418-12D2-11D7-8EED-00B0D03D76EC",但似乎代码:

        conURL = "btspp://localhost:68EE141812D211D78EED00B0D03D76EC;"
                + "authenticate=false;encrypt=false;name=MySampleApp";
        server = (StreamConnectionNotifier)
                Connector.open(conURL);

添加默认串行端口服务UUID"00001101-0000-1000-8000-00805F9B34FB"作为ServiceClassIDList属性:

现在,有趣的是Android方法BluetoothDevice.fetchUuidsWithSdp(); 似乎取了默认的"00001101-0000-1000-8000-00805F9B34FB"UUID,而不是我的"68EE1418-12D2-11D7-8EED-00B0D03D76EC"UUID,将我的服务与手机的默认串口服务重叠.

类似中世纪蓝牙网络扫描仪的东西,它识别我的服务,但广告为"00001101-0000-1000-8000-00805F9B34FB":

我能做什么,除去额外的UUID那个JAVAME自动添加到我的服务？

请帮忙,谢谢!

EDIT2

好的,问题出在索尼爱立信手机上.显然他们UUID {0x1101}在我的自定义之前插入标准串口UUID,而三星和诺基亚手机,例如,UUID在我的服务记录上插入这个标准.Android似乎只获取0x001服务记录中属性的第一个值,因此,将我的服务与某些设备附带的默认串行端口混淆.

所以解决方案将是:

有没有办法使用当前的Android API来获取更多servicerecord属性ServiceClassID (0x001)？

要么

有没有办法servicerecord在调用"acceptAndOpen"-JAVAME-后更新存储在服务发现数据库(SDDB)上的内容？- 我已经LocalDevice.updateRecord在服务上创建使用了SDDB它,它可以在模拟器上运行,但是在实际设备上提供异常并且什么都不做.
