如何將視頻文件轉換爲Base64字符串，反之亦然？

Question

我想要的視頻文件轉換爲Base64字符串，反之亦然，目前我的視頻是原始文件夾內。這是我的代碼：

String uriPath = "android.resource://com.hello.videouploaddemo/raw/sendvideo"; 

Answer 1

首先轉換RAW文件爲byte[]

InputStream inStream = context.getResources().openRawResource(R.raw.sendvideo); 
byte[] video = new byte[inStream.available()]; 

使用在Android Base64類

public static byte[] encode (byte[] input, int flags)

byte[] base64 = Base64.encode(video,Base64.DEFAULT); 

public static byte[] decode (byte[] input, int offset, int len, int flags)

byte[] rowVideoAgain = Base64.decode(base64,0,base64.length,Base64.DEFAULT);

你應該開始這一場的AsyncTask http://developer.android.com/reference/android/os/AsyncTask.html
