我是新android开发。我想使用蓝牙发送数据，但以下情况除外来了。

 连接到蓝牙失败。java.io.IOException异常：[JSR82]连接：连接还没有建立（或失败中止）。在android.bluetooth.BluetoothSocket.connect（BluetoothSocket.java:397）odacPkg.odac.BluetoothCommunication.run（CommunicationActivity.java:493） 

以下是我的源$ C ​​$ C。

 最后UUID applicationUUID = UUID.fromString（00001101-0000-1000-8000-00805F9B34FB）;        btDevice = bluetoothAdapterObj.getRemoteDevice（deviceMAC.toUpperCase（））;        尝试{            的BluetoothSocket btSocket = btDevice.createRfcommSocketToServiceRecord（applicationUUID）;            btSocket.connect（）;            的OutputStream outStream = btSocket.getOutputStream（）;            outStream.write（送出数据）;            btSocket.wait（CommunicationActivity.PACK_TIMEOUT）;            的InputStream inStream中= btSocket.getInputStream（）;            inStream.read（receiveData的）;            outStream.flush（）;            outStream.close（）;            outStream.close（）;        }        赶上（例外五）{        } 

解决方案

这不是从你的code来一个问题，我解决它只是重新启动Android设备。我猜疗法采用的是Android设备，至少在4.1版本果冻豆的执行系统，一些奇怪的事情。

I am new to android development. I want to send data using Bluetooth but the following exception coming.

Connecting To Bluetooth Failed.
java.io.IOException: [JSR82] connect: Connection is not created (failed or aborted).
at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:397)
odacPkg.odac.BluetoothCommunication.run(CommunicationActivity.java:493)

Following is my source code.

        final UUID applicationUUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
        btDevice=bluetoothAdapterObj.getRemoteDevice(deviceMAC.toUpperCase());
        try {               
            BluetoothSocket btSocket = btDevice.createRfcommSocketToServiceRecord(applicationUUID);
            btSocket.connect();
            OutputStream outStream = btSocket.getOutputStream();
            outStream.write(sendData);
            btSocket.wait(CommunicationActivity.PACK_TIMEOUT);
            InputStream inStream = btSocket.getInputStream();
            inStream.read(receiveData);
            outStream.flush();
            outStream.close();
            outStream.close();
        }   
        catch (Exception e) {

        }

It's not an issue coming from your code, I solved it simply rebooting android devices. I guess ther is something strange in the operative system of android devices , at least for version 4.1 jelly bean.
