Android蓝牙输入/输出流：发送约1400字节，接收1008字节

我试图在两部安卓4.0.1手机之间发送数据，当我发送数据时，另一端没有收到完整的阵列

我的代码：

byte[] buffer = new byte[4096];
int bytes;

bytes = inputStream.read(buffer);
// bytes = 1008
// buffer[1008..4095] = 0 
// =================== other side =============================
byte[] message = Tools.concatByteArray(response, authorizationMessage);

// Debug tells me that the array has 1400 bytes
outputStream.write(message);
outputStream.flush();

调试中的消息包括：

你设置了缓冲区大小吗？

---

通常你会一直读到没有更多的数据。

我不得不解决一个类似的错误。唯一相关的问题就在这条线索上，至今仍未解决。所以我不得不自己寻找原因和解决办法：）

原因是安卓蓝牙系统似乎以1008字节为单位发送数据。 因此，您需要在while循环中读取流，并连接接收到的字节

下面是您的代码应该如何重写：

byte[] buffer = new byte[4096];
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int bytes;

while ((bytes = inputStream.read(buffer, 0, buffer.length)) > -1) {
          baos.write(buffer, 0, bytes);
          baos.flush();
}
byte[] message = baos.toByteArray();

// =================== other side =============================
byte[] message = Tools.concatByteArray(response, authorizationMessage);
outputStream.write(message);
outputStream.flush();
outputStream.close(); // <-- important! so the receiver knows that it is the end of data

byte[]buffer=新字节[4096]；
ByteArrayOutputStream bas=新的ByteArrayOutputStream（）；
整数字节；
而（（bytes=inputStream.read（buffer，0，buffer.length））>-1）{
写入（缓冲区，0，字节）；
paos.flush（）；
}
字节[]消息=baos.toByteArray（）；
//==================================另一边=============================
字节[]消息=Tools.concatByteArray（响应、授权消息）；
outputStream.write（消息）；
outputStream.flush（）；
outputStream.close（）；// 请检查零件。如你所见

您应该使用专用线程进行所有流读取和
写作。这一点很重要，因为读（字节[]）和写（字节[]）
方法是阻止调用。读取（字节[]）将阻止，直到
要从流中读取的内容。写入（字节[]）通常不会
阻止，但如果远程设备未启动，则可以阻止流量控制
足够快地调用read（byte[]），中间缓冲区
满满的。因此，线程中的主循环应该专用于读取
从输入流

当我开始编码我的读线程时，InputStream的read（byte[]）方法将阻止执行，直到有所需的字节数为止。但事实并非如此。我发现它确实会阻塞，直到有“东西”可以从流中读取（我以前错过的部分）

考虑你的包裹是什么；0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09，通过OutputStream写入并刷新发送。在一次read（）调用中，您可能仍然只得到它的一部分（甚至是1字节->0x01），而在下一次read（）调用中，您可能会得到它的其余部分（0x02和其余部分）。在这种情况下，read（）的返回值将等于1，incomingBytes[0]将为0x01，其他元素将为0
是缓冲区初始化为4096字节，如何确保我们期望的消息何时完成？！如果我等待9个字节，我得到1，然后是8，但下一次是9，下一次是4，然后是6，然后是8，然后是正确的9，依此类推。。。？！？！有趣的是，在我使用的协议中，我可以使用crc验证，但当我收到如此多的剪切消息时，crc没有任何意义，直到我确定我有一整条消息。。。因此，我需要实现剪切、移动、加入字节数组的逻辑，并且消息每秒提交200多次…：（有什么帮助吗？@Ewoks完全正确。我们使用的包大小超过8字节，后来，出于效率考虑，它扩展得更多。因此，除非包大小为1字节，否则您永远不会后悔实现所需的逻辑。我实现了一个类似流的函数类，收集所有字节，在需要时将它们转换为固定大小的包接收到所有包，抛出清除相关字节的完整包。这样，即使在单个inputStream.read（）中接收到1个字节或2个包（使用8字节的包大小很有可能），也会得到2个包或根本没有。。
