how to send image (bitmap) to server in android with multipart-form data json

Question

I have code to upload image to server and it works ,

HttpEntity resEntity; HttpClient httpClient = new DefaultHttpClient(); HttpPost post = new HttpPost(Constants.url_create_product); MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); File file= new File(path); FileBody bin = new FileBody(file); reqEntity.addPart("phone", new StringBody(mPhoneNumber)); reqEntity.addPart("prod_title", new StringBody(namapro)); reqEntity.addPart("prod_price", new StringBody(hargapro)); reqEntity.addPart("prod_desc", new StringBody(despro)); reqEntity.addPart("prod_order", new StringBody(orderpro)); reqEntity.addPart("prod_image", bin); post.setEntity(reqEntity); HttpResponse response = httpClient.execute(post); resEntity = response.getEntity(); String response_str = EntityUtils.toString(resEntity); Gson gson = new Gson(); gson.toJson(response_str); if (resEntity != null) { Log.i("RESPONSE",response_str); runOnUiThread(new Runnable(){ public void run() { try { Toast.makeText(getApplicationContext(),"Upload Complete. Check the server uploads directory.", Toast.LENGTH_LONG).show(); } catch (Exception e) { e.printStackTrace(); } } }); }

But i have menu image editor . that editor is crop image and thats code return bitmap value like this

Bundle extras = data.getExtras(); if (extras != null) { photo = extras.getParcelable("data"); mImageView.setImageBitmap(photo); } File f = new File(mImageCaptureUri.getPath()); if (f.exists()) f.delete(); break;

I wanna ask , how solution to send image to server with parameter bitmap. As you know my code to send image now use parameter path (string).

ByteArrayOutputStream baos = new ByteArrayOutputStream(); photo.compress(Bitmap.CompressFormat.JPEG, 100, baos); byte[] imageBytes = baos.toByteArray(); String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);

Then send this encodedImage as a String and in your server you will need to decode it in order to get the image itself.

sorry , iam newbie , so how server to decode it in order to get the image itself??

Carnal Over a year ago

depends on what language you're using on your server. PHP has built in method for this. Just google the language on server + decode image string.

*use three library
1.httpclient-4.3.6
2.httpcore-4.3.3
3.httpmime-4.3.6

 byte[] data = null; try { String url = "http://andapp.freetings.in/testbyme.php?"; HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); MultipartEntity entity = new MultipartEntity(); if(imageBitmap!=null){ ByteArrayOutputStream bos = new ByteArrayOutputStream(); imageBitmap.compress(CompressFormat.JPEG, 100, bos); data = bos.toByteArray(); entity.addPart("uplod_img", new ByteArrayBody(data,"image/jpeg", "test2.jpg")); } // entity.addPart("category", new StringBody(categoryname,"text/plain",Charset.forName("UTF-8"))); entity.addPart("category", new StringBody(catid,"text/plain",Charset.forName("UTF-8"))); entity.addPart("your_contact_no", new StringBody(phone,"text/plain",Charset.forName("UTF-8"))); entity.addPart("your_emailid", new StringBody(email,"text/plain",Charset.forName("UTF-8"))); entity.addPart("your_name", new StringBody(name,"text/plain",Charset.forName("UTF-8"))); httppost.setEntity(entity); HttpResponse resp = httpclient.execute(httppost); HttpEntity resEntity = resp.getEntity(); String string=EntityUtils.toString(resEntity); // Log.e("sdjkfkhk", string); return resEntity; } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }

u have need add three jar file those are httpclient-4.1.jar, httpcore-4.1.jar and httpmime-4.1.jar in libs folder
