ByteArrayOutputStream throwing OutOfMemoryError

Question

I'm trying to read a byte array of an image using the following code but it throws an out of memory exception. I have commented where the exception occurs.

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

You are ignoring that how much number of bytes are actually read.

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