Android的蓝牙打印机连接？ [英] android bluetooth printer connection?

问题描述

我不得不J2ME应用程序打印数据字节打印机。
但现在，我已经到code转换到Android code。

i had J2ME application to print data byte to printer. But now, i have to convert that code to android code.

我的问题是：
我不能数据字节[]移动打印机从我的设备Galaxy Tab的升级Froyo通过蓝牙发送？

My problem is : i can't send data byte[] to mobile printer from my device Galaxy Tab Froyo via bluetooth?

在这里我简单的code：

here my simple code :

UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
BluetoothSocket btSocket btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
btSocket.connect();
OutputStream outStream = btSocket.getOutputStream();
String message = "this is message";
byte[] msgBuffer = message.getBytes();
outStream.write(msgBuffer.length);
outStream.write(msgBuffer);

当我看到LogCat中，它表明我通过与没有错误的所有进程。

when i see the LogCat, it show that i through all that process with no error.

谁能帮助我？

在预先感谢

推荐答案

这在我脑海的第一件事是 outStream.close（），你忘了写。虽然我很可能错了。

The first thing that comes to my mind is outStream.close() that you forgot to write. Though I am most probably wrong
