Android跨进程通讯之LocalSocket和LocalServerSocket

先贴上LocalSocket的代码：

//创建对象
LocalSocket localSocket = new LocalSocket();
//连接socketServerSocket
localSocket.connect(new LocalSocketAddress(String addrStr));

获取localSocket的输入输出流：

outputStream = localSocket.getOutputStream();
inputStream = localSocket.getInputStream();

写入数据：

outputStream.write("输入的内容".getBytes());

接收数据：

try {    
      int readed = inputStream.read();
      int size = 0;
      byte[] bytes = new byte[0];
      while (readed != -1) {
          byte[] copy = new byte[500000]; 
          System.arraycopy(bytes, 0, copy, 0, bytes.length);
          bytes = copy;
          bytes[size++] = (byte) readed; 
          //以换行符标识成结束
          if ('\n' == (byte) readed) {
              String resultStr = new String(bytes, 0, size);                                                          break;
        } 
       readed = inputStream.read();
    }
} catch (IOException e) {
        return false;
}

至此，LocalSocket部分的代码已经完毕了，注意捕获异常。

LocalServerSocket部分代码马上贴上：

//初始化
try {
    //socketAddress需跟localSocket地址一致，否则无法连接上
    serverSocket = new LocalServerSocket(socketAddress);
} catch (IOException e) {
    LoggerHelper.e("Server to establish connection exception:" + e.toString());
    e.printStackTrace();
    return false;
}
try {
    //获取接收的LocalSocket
    localSocket = serverSocket.accept();
    //设置缓冲大小
    localSocket.setReceiveBufferSize(ConstantConfig.BUFFER_SIZE);
    localSocket.setSendBufferSize(ConstantConfig.BUFFER_SIZE);
} catch (IOException e) {
    e.printStackTrace();
    LoggerHelper.d("Waiting to be linked to a bug,error:" + e.toString());
    return false;
}

获取输入输出流一致：

if (localSocket != null) {
    try {
        inputStream = localSocket.getInputStream();
        outputStream = localSocket.getOutputStream();
        /** 允许一直接收数据，一直到连接被断开，则认为应用端退出，自己也退出 */
        while (isLock && receiveData()) ;
    } catch (IOException e) {
        LoggerHelper.e("Get stream exception:" + e.toString());        e.printStackTrace();
        return false;
    }
}

已经ok啦。。。
