exo*_*ist 21 android bluetooth file transfer
我想在Android设备上通过蓝牙发送文件.我做了发现,连接并制作了一个蓝牙插座.问题是当我在蓝牙套接字的输出流中写字节数组时,接收方虽然接受正在发送的内容但没有收到任何内容.
这就是我在做什么(坏的是蓝牙适配器)
请指教.
try
{
BluetoothDevice dev = bad.getRemoteDevice(a);
bad.cancelDiscovery();
dev.createRfcommSocketToServiceRecord(new UUID(1111, 2222));
Method m = dev.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
bs = (BluetoothSocket) m.invoke(dev, Integer.valueOf(1));
bs.connect();
tmpOut = bs.getOutputStream();
}catch(Exception e)
{
}
File f = new File(filename);
byte b[] = new byte[(int) f.length()];
try
{
FileInputStream fileInputStream = new FileInputStream(f);
fileInputStream.read(b);
}catch(IOException e)
{
Log.d(TAG, "Error converting file");
Log.d(TAG, e.getMessage());
}
try {
tmpOut.write(b);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
