我目前正在设计一个需要连接到设备、写入/读取数据并可靠关闭连接的应用程序。目前我有写/读稳固。我的断开连接然后重新连接非常不可靠,并且实际上经常使手机崩溃..有时是 Eclipse。我一直在浏览许多文章试图弄清楚它,但......没有运气......
****连接功能**
public boolean connect()
{
ConfigData.getInstance();
BluetoothSocket tmp = null;
BluetoothDevice device = ConfigData.m_SharedBluetoothDevice;
Method m;
try {
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);//(BluetoothSocket)
m.invoke(device, 1);
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
ConfigData.m_SharedBluetoothSocket = tmp;
try {
ConfigData.m_SharedBluetoothSocket.connect();
ConfigData.bIsBTConnected = true;
} catch (IOException e) {
try {
closeSocket();
m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
tmp = (BluetoothSocket) m.invoke(device, 1);
} catch (SecurityException e1) {
e1.printStackTrace();
} catch (NoSuchMethodException e1) {
e1.printStackTrace();
} catch (IllegalArgumentException e1) {
e.printStackTrace();
} catch (IllegalAccessException e1) {
e.printStackTrace();
} catch (InvocationTargetException e1) {
e.printStackTrace();
}
ConfigData.m_SharedBluetoothSocket = tmp;
try {
ConfigData.m_SharedBluetoothSocket.connect();
ConfigData.bIsBTConnected = true;
} catch (IOException e1) {
ConfigData.m_BluetoothException += e1.toString();
ConfigData.bIsBTConnected = false;
return false;
}
e.printStackTrace();
return true;
}
return true;
}
****断开功能**
public void destroySocket()
{
try {
if(m_InStream != null)
{
m_InStream.close();
m_InStream = null;
}
if(m_OutStream != null)
{
m_OutStream.close();
m_OutStream = null;
}
if(ConfigData.m_SharedBluetoothSocket != null)
{
ConfigData.m_SharedBluetoothSocket.close();
ConfigData.m_SharedBluetoothSocket = null;
}
if(m_InStream == null && m_OutStream == null && ConfigData.m_SharedBluetoothSocket == null)
{
ConfigData.bIsBTConnected = false;
}
} catch (IOException e1) {
m_InStream = null;
m_OutStream = null;
ConfigData.m_SharedBluetoothSocket = null;
e1.printStackTrace();
}
}
所以断开连接成功并返回所有内容。问题是,当我重新连接时,它会在第二次连接尝试时阻塞,要么只是坐在那里,要么让手机完全崩溃,导致几次重启。
有人在这里有什么建议吗?它非常令人沮丧。任何帮助将非常感激!!
谢谢和演出!TxAg
