Question

Answer 1

缓冲区太大。试试这个:

    InputStream content = new FileInputStream(file);

    int numRead;
    final int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];
    ByteArrayOutputStream outString = new ByteArrayOutputStream();
    try{
        while ((numRead = content.read(buffer)) != -1) {
            outString.write(buffer, 0, numRead);
        }
    } finally {
        content.close();
    }
    return new String(outString.toByteArray());
