ByteArrayOutputStream抛出OutOfMemoryError

Question

我想使用下面的代码读取图像的字节数组，但它会引发内存不足异常。我评论了发生异常的位置。

byte[] bBuffer = new byte[300000]; // 
ByteArrayBuffer baf = new ByteArrayBuffer(300000); 
int total = 0; 
ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
try 
{ 
    int read = 0;   
    while ((dis.read(bBuffer, 0, bBuffer.length)) != -1) { 
     baos.write(bBuffer, 0, bBuffer.length); // Exception occurs here   
     Log.d("outputImageBytes", "Reading Image Bytes: " + bBuffer.length + " " + read++); 
    } 
    //baos.flush(); 
} 
catch (Exception e) 
{ 
    Log.e("outputImageBytes", "Exception Occured while reading image bytes: " + e.getMessage()); 
    e.getMessage(); 
} 

Answer 1

您忽略了实际读取的字节数量。

int numberofBytesRead=dis.read(bBuffer, 0, bBuffer.length); 
baos.write(bBuffer, 0, numberOfBytesRead);
