当我尝试启动蓝牙套接字时，我收到此消息，并且我的Android应用程序崩溃而没有错误日志：

编辑：
在我的清单中我有：
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
对于蓝牙连接，我首先搜索设备：
private void searchBWD() {
Log.w(TAG,"SEARCH : "+search);
if(search > Globals.MAX_SEARCH){
stop = true;
showCloseDialog(true);
pwrOnLabel.setText(R.string.lbl_power_on2);
isSearching = false;
}else if(!stop){
if(!controller.isDeviceStored()) {
search++;
if(D) Log.d(TAG, "start search BWD devices");
showProgressDialog();
pwrOnLabel.setText(R.string.msg_scanning_bwd);
mNewDevices = new ArrayList<String>();
try{
// If we're already discovering, stop it
if (mBluetoothAdapter.isDiscovering()) {
mBluetoothAdapter.cancelDiscovery();
}
// Request discover from BluetoothAdapter
mBluetoothAdapter.startDiscovery();
}catch (Exception e) {
e.printStackTrace();
}
}else connectionStart();
}
}
并且比较它是否是我正在寻找的设备，如果是我停止搜索并开始连接：
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent){
String action = intent.getAction();
if(D) Log.v(TAG, "onReceive action:"+action);
// When discovery finds a device
if (BluetoothDevice.ACTION_FOUND.equals(action)){
// Get the BluetoothDevice object from the Intent
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
if (D) Log.d(TAG, "deviceFound :" + device.getName() + "[" + device.getAddress() + "]");
mNewDevices.add(device.getAddress());
// If the founded device is the BWD, stop discovering
if (device.getName() != null){
if(device.getName().toUpperCase().startsWith(Globals.REMOTEBTNAME.toUpperCase())
| device.getName().toUpperCase().startsWith(Globals.REMOTEBTNAME2.toUpperCase())) {
mBluetoothAdapter.cancelDiscovery();
}
}
// When discovery is finished, change the Activity title
} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
if (D) Log.i(TAG, "scanCompleted:" + mNewDevices.size());
hideProgressDialog();
// Look for the bluetooth address of the S4B(s)
int nbBWGDiscovered = 0;
BluetoothDevice device;
String bBWDAddress = "";
for (int i = 0; i < mNewDevices.size(); i++) {
device = mBluetoothAdapter.getRemoteDevice(mNewDevices.get(i));
try {
if (D) Log.d(TAG, "Found device name:" + device.getName() + ", address:" + device.getAddress());
if (device.getName() != null){
if(device.getName().toUpperCase().startsWith(Globals.REMOTEBTNAME.toUpperCase())
| device.getName().toUpperCase().startsWith(Globals.REMOTEBTNAME2.toUpperCase())) {
nbBWGDiscovered++;
bBWDAddress = device.getAddress();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
if (D) Log.d(TAG, "nbBWGDiscovered =" + nbBWGDiscovered);
switch (nbBWGDiscovered) {
case 0:
// error, 0 bwg found
searchBWD();
break;
case 1:
storeBWGDevice(bBWDAddress, true);
connectionStart();
break;
default:
// to many bwg found to localize yours
searchBWD();
break;
}
} else if(ACTION_CONNECTED.equals(action)) { ........
以下是连接过程：
public void connectionStart() {
if(!stop){
if(D) Log.d(TAG, " X===> connectionStart to:"+ controller.getDeviceAddress());
showProgressDialog();
pwrOnLabel.setText(R.string.alert_device_found);
Runnable reConnect = new Runnable() {
public void run() {
Utils.pause(200);
protectionService.putExtra(DEVICE_ADDRESS, controller.getDeviceAddress());
Welcome.this.startService(protectionService);
}
};
Thread thread = new Thread(null, reConnect, "ConnectToBWD");
thread.start();
}
}
这是'ConnectThread'过程，我尝试用我的设备打开蓝牙插座：
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
if(D) Log.d(TAG, "start connectThread ");
mmDevice = device;
BluetoothSocket connection = null;
// Get a BluetoothSocket for a connection with the
// given BluetoothDevice
try {
//connection = device.createRfcommSocketToServiceRecord(MY_UUID);
if(D) Log.i(TAG,"Create RF Socket");
Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class });
connection = (BluetoothSocket) m.invoke(device, 1);
Utils.pause(100);
} catch (Exception e) {
Log.e(TAG, "create() failed", e);
}
mmSocket = connection;
if(D) Log.i(TAG,"Socket initialized");
}
public void run() {
if(D) Log.i(TAG, "BEGIN mConnectThread");
setName("ConnectThread");
if (mmSocket != null) {
// Always cancel discovery because it will slow down a connection
if (mAdapter.isDiscovering()){
mAdapter.cancelDiscovery();
if(D) Log.i(TAG,"cancel discovering before connect");
}
// Make a connection to the BluetoothSocket
try {
// This is a blocking call and will only return on a
// successful connection or an exception
if(D) Log.i(TAG,"Start socket connection");
mmSocket.connect();
if(D) Log.i(TAG,"End of socket connection");
} catch (Exception e) {
Log.e(TAG, "socket connect failed", e);
// Close the socket
try {
mmSocket.close();
if(D) Log.i(TAG,"close socket");
} catch (IOException e2) {
Log.e(TAG,"unable to close() socket during connection failure",e2);
}
// Start the service over to restart listening mode
BluetoothConnectionService.this.start();
connectionFailed();
return;
}
// Reset the ConnectThread because we're done
synchronized (BluetoothConnectionService.this) {
mConnectThread = null;
}
// Start the connected thread
connected(mmSocket, mmDevice);
} else {
connectionFailed();
BluetoothConnectionService.this.start();
}
}
public void cancel() {
try {
if (mmSocket != null) {
mmSocket.close();
}
} catch (IOException e) {
Log.e(TAG, "close() of connect socket failed", e);
}
}
}
就在这里，当打开套接字失败时，我在关闭套接字后收到DEBUG消息。
答案 0 :(得分：1)
好的，那么没有代码，你必须记住，必须通过添加以下内容在Manifest中声明蓝牙访问：
<uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"></uses-permission>
然后执行以下操作：
BluetoothAdapter bt_adapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = bt_adapter.getBondedDevices();
if (pairedDevices.size() > 0) {
// Loop through paired devices
for (BluetoothDevice device : pairedDevices) {
// Add the name and address to an array adapter to show in a ListView
String name = device.getName();
//BT2IR
if (name.contains("K01-Blue")) {
GlobalVars.bluetooth.bt_device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(device.getAddress());
break;
}
}
}
