ByteArrayOutputStream拋出OutOfMemoryError

Question

我想使用下面的代碼讀取圖像的字節數組，但它會引發內存不足異常。我評論了發生異常的位置。

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(); 
}

您忽略了實際讀取的字節數量。

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