问题：当SDK升级到23时候提示不存在**org.apache.http.util.ByteArrayBuffer**

1、使用ByteArraybuffer的代码

BufferedInputStream bis = new BufferedInputStream(is);  
            ByteArrayBuffer baf = new ByteArrayBuffer(50);  
            while ((current = bis.read()) != -1) {  
                baf.append((byte) current);  
            }  
            FileOutputStream fos = new FileOutputStream(file);  
            fos.write(buffer.toByteArray());

2、使用ByteArrayOutputStream替代的代码

BufferedInputStream bis = new BufferedInputStream(is);  
     ByteArrayOutputStream buffer = new ByteArrayOutputStream();  
     //We create an array of bytes  
     byte[] data = new byte[50];  
     int current = 0;  
     while((current = bis.read(data,0,data.length)) != -1){  
           buffer.write(data,0,current);  
     }  
     FileOutputStream fos = new FileOutputStream(file);  
     fos.write(buffer.toByteArray());  
     fos.close();
