Android蓝牙:连接()/断开()
问题描述:
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
好。我正在使用HTC Incredible 2.1update1操作系统。我看到那篇文章,但我也看到它已经回答并尝试了这些答案,并且没有任何积极的结果。你知道是否/何时Incredible应该获得Froyo? 虽然谢谢! – TxAg 2010-08-23 13:51:33
