Voici la méthode que j'ai utilisée pour télécharger l'image sur le serveur.

/** 
* Upload Image to server 
* 
* @param file    image to be saved 
* @param compressorQuality quality of image 
* @return path of uploaded image in server 
*/ 
private String uploadImage(Bitmap file, int compressorQuality) { 
    String final_upload_filename = "demo_image.png"; 
    String response = null; 
    HttpURLConnection conn = null; 
    try { 
     String lineEnd = "\r\n"; 
     String twoHyphens = "--"; 
     String boundary = "---------------------------14737809831466499882746641449"; 
     URL url = new URL("image_upload_url"); 
     conn = (HttpURLConnection) url.openConnection(); 
     conn.setDoInput(true); 
     conn.setDoOutput(true); 
     conn.setUseCaches(false); 
     conn.setRequestMethod("POST"); 
     conn.setRequestProperty("Connection", "Keep-Alive"); 
     conn.setRequestProperty("ENCTYPE", "multipart/form-data"); 
     conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); 
     conn.setRequestProperty("uploaded_file", final_upload_filename); 
     DataOutputStream dos = new DataOutputStream(conn.getOutputStream()); 
     dos.writeBytes(lineEnd + twoHyphens + boundary + lineEnd); 
     dos.writeBytes("Content-Disposition: form-data; name=\"userfile\"; filename=\"" + final_upload_filename + "\"" + lineEnd); 
     dos.writeBytes("Content-Type: application/octet-stream" + lineEnd); 
     dos.writeBytes(lineEnd); 
     file.compress(CompressFormat.PNG, compressorQuality, dos); 
     dos.writeBytes(lineEnd); 
     dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
     dos.flush(); 
     dos.close(); 
     InputStream is = conn.getInputStream(); 
     ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
     int bytesRead; 
     byte[] bytes = new byte[1024]; 
     while ((bytesRead = is.read(bytes)) != -1) { 
      baos.write(bytes, 0, bytesRead); 
     } 
     byte[] bytesReceived = baos.toByteArray(); 
     baos.close(); 
     is.close(); 
     response = new String(bytesReceived); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } finally { 
     if (conn != null) { 
      conn.disconnect(); 
     } 
    } 
    return response; 
} 

Vous pouvez utiliser cette méthode comme:

Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri); 
String server_response = uploadImage(bitmap, 100); 

J'espère que ça aide!
