我目前正在设计一个应用程序，它需要连接到设备，写入/读取数据，并可靠地关闭连接。目前我有写/读固体。我的断开连接然后重新连接非常不可靠，并且经常实际上使手机崩溃。我一直在寻找通过大量文章试图弄清楚和..没有运气..Android蓝牙：连接()/断开()
****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();
}
}
因此断开连接成功并返回一切为空。问题是，当我在第二次连接尝试中重新连接数据块时，它们会坐在那里或完全崩溃，导致几次重新启动。
有没有人有任何建议吗？它非常令人沮丧。任何帮助将非常感激！！
谢谢Gig'Em！ TxAg
