如何将所有文件从SD卡发送到服务器我可以通过此方式将文件从设备推送到服务器代码：

public void btnclick(View v) {

        String pathToOurFile = "/mnt/sdcard/" + "q.3gp";
        String urlServer = "http://www.google.com/upload.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(
                    pathToOurFile));

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

            // Allow Inputs & Outputs
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("ENCTYPE", "multipart/form-data");
            connection.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);
            connection.setRequestProperty("uploaded_file", "gopivideo");
            outputStream = new DataOutputStream(connection.getOutputStream());
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream
                    .writeBytes("Content-Disposition: form-data; name=\"sample\";filename=\""
                            + pathToOurFile + "\"" + lineEnd);
            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();

            Toast.makeText(getApplicationContext(),
                    serverResponseCode + "," + serverResponseMessage,
                    Toast.LENGTH_LONG).show();

            fileInputStream.close();
            outputStream.flush();
            outputStream.close();
        } catch (Exception ex) {
            // Exception handling
        }
    }
}

这对于通过单次推送将任何类型的文件上传到服务器非常有用但是需要的是循环sdcard中的所有文件并逐个发送。谢谢

您可以使用Multipart post请求执行此操作:(这样，您不需要创建json）

   HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(serverURL);
    MultipartEntity postEntity = new MultipartEntity();
    File file = new File("Your File path on SD card");
    postEntity.addPart("fileupload", new FileBody(file, "image/jpeg"));
    postEntity.addPart("loginKey", new StringBody(""+loginKey));
    postEntity.addPart("message", new StringBody(message));
    postEntity.addPart("token", new StringBody(token));
    post.setEntity(postEntity);
    response = client.execute(post);

并添加Mime4库

从android设备发送文件到服务器？
