将蓝牙输入流转换为图像，java android app

Question

如何将蓝牙输入流转换为 java android 应用程序中的图像？ 数据被分成块。在输入流中逐块捕获，但它不能容纳超过一个块。这个想法是将所有块（逐个流）放在一个字节数组中，然后制作一个位图。

    private val mmInStream: InputStream = mmSocket.inputStream
           private val mmOutStream: OutputStream = mmSocket.outputStream
           private val mmBuffer: ByteArray = ByteArray(1024) // mmBuffer store for the stream
    
           override fun run() {
               var numBytes: Int // bytes returned from read()
    
               // Keep listening to the InputStream until an exception occurs.
               while (true) {
                   // Read from the InputStream.
                   numBytes = try {
                       mmInStream.read(mmBuffer)
                   } catch (e: IOException) {
                       Log.d(TAG, "Input stream was disconnected", e)
                       break
                   }
    
                   }


// Now the bytes read can be write to a file let's say .png/.jpeg image file.
   fun write(bytes: ByteArray) {
       try {
           mmOutStream.write(bytes)
       } catch (e: IOException) {
           Log.e(TAG, "Error occurred when sending data", e)
          
           }
      
       }
      
   }
