android 视频文件转base64

以下是两种Android视频文件转Base64的方法：

//方法一：需要导入Jar包
/**
 * 文件转Base64.
 * @param path
 * @return
 * @throws Exception
 */
public static String fileToBase64(String path) throws Exception {
    File file = new File(path);
    FileInputStream inputFile = new FileInputStream(file);
    byte[] buffer = new byte[(int) file.length()];
    inputFile.read(buffer);
    inputFile.close();
    return new BASE64Encoder().encode(buffer);
}

//方法二：不需要导入Jar包
/**
 * 文件转Base64.
 * @param filePath
 * @return
 */
public static String file2Base64(String filePath) {
    FileInputStream objFileIS = null;
    try {
        objFileIS = new FileInputStream(filePath);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    ByteArrayOutputStream objByteArrayOS = new ByteArrayOutputStream();
    byte[] byteBufferString = new byte[1024];
    try {
        for (int readNum; (readNum = objFileIS.read(byteBufferString)) != -1; ) {
            objByteArrayOS.write(byteBufferString, 0, readNum);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    String videodata = Base64.encodeToString(objByteArrayOS.toByteArray(), Base64.DEFAULT);
    return videodata;
}
