尝试

HttpURLConnection connection = null; 
    DataOutputStream outputStream = null; 
    DataInputStream inputStream = null; 


    String pathOfYourFile = "/sdcard/videoName.3gp"; 
    String urlServer = "http://....../uploadvideo.php"; 
    String lineEnd = "\r\n"; 
    String twoHyphens = "--"; 
    String boundary = "*****"; 

    int bytesRead, bytesAvailable, bufferSize; 
    byte[] buffer; 
    int maxBufferSize = 1*1024*1024; 

    try 
    { 
    FileInputStream fileInputStream = new FileInputStream(new File(pathOfYourFile)); 

    URL url = new URL(urlServer); 
    connection = (HttpURLConnection) url.openConnection(); 

    // Allow Inputs & Outputs 
    connection.setDoInput(true); 
    connection.setDoOutput(true); 
    connection.setUseCaches(false); 

    // Enable POST method 
    connection.setRequestMethod("POST"); 

    connection.setRequestProperty("Connection", "Keep-Alive"); 
    connection.setRequestProperty("Content-Type", "multipart/form-data;boundary"); 

    outputStream = new DataOutputStream(connection.getOutputStream()); 
    outputStream.writeBytes(twoHyphens + boundary + lineEnd); 
    outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathOfYourFile); 
    outputStream.writeBytes(lineEnd); 

    bytesAvailable = fileInputStream.available(); 
    bufferSize = Math.min(bytesAvailable, maxBufferSize); 
    buffer = new byte[bufferSize]; 

    // Read file 
    bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

    while (bytesRead > 0) 
    { 
    outputStream.write(buffer, 0, bufferSize); 
    bytesAvailable = fileInputStream.available(); 
    bufferSize = Math.min(bytesAvailable, maxBufferSize); 
    bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
    } 

    outputStream.writeBytes(lineEnd); 
    outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

    // Responses from the server (code and message) 
    int serverResponseCode = connection.getResponseCode(); 
    String serverResponseMessage = connection.getResponseMessage(); 
    Log.d("ServerCode",""+serverResponseCode); 
    Log.d("serverResponseMessage",""+serverResponseMessage); 
    fileInputStream.close(); 
    outputStream.flush(); 
    outputStream.close(); 
    } 
    catch (Exception ex) 
    { 
     ex.printStackTrace(); 
    } 
}
