Upload Large Image in Base64 to Server

I take a picture using the android.hardware.Camera API. I then convert it to a Bitmap of half the actual size, compress it to a JPEG of quality 80, convert it to Base64 and send it to the server as follows.
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.NO_WRAP);
String json_response = "";
try {
URL url = new URL("https://example.com/api_endpoint");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write("?reg=" + regCode);
writer.write("&img=" + encoded);
writer.flush();
writer.close();
os.close();
Log.d("Auth", conn.getResponseCode() + "");
InputStreamReader in = new InputStreamReader(conn.getInputStream());
BufferedReader br = new BufferedReader(in);
String text = "";
while ((text = br.readLine()) != null) {
json_response += text;
}
conn.disconnect();
} catch (IOException e) {
Log.d(getClass().getName(), "" + e.getMessage());
}
This works as expected. Now, If I don't resize the image and keep the quality 100%, how should I go about to avoid an OutOfMemoryError? My application requires the image to be in the full resolution and best quality possible.
My questions are:
Is the way I am uploading the correct way?
How to send Image is best quality without OutOfMemoryError i.e. how to optimize RAM usage in this process?

Here is my image/file uploader class:
public class ImageUploader extends AsyncTask<String, String, String> {
File imageFile = null;
String fileName = null;
public ImageUploader(File imageFile, String fileName){
this.imageFile = imageFile;
this.fileName = fileName;
}
#Override
protected String doInBackground(String... params) {
String url_str = params[0];
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
String Tag="fSnd";
try {
URL url = new URL(url_str);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("POST");
c.setDoInput(true);
c.setDoOutput(true);
c.setRequestProperty("Connection", "Keep-Alive");
c.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
c.connect();
DataOutputStream dos = new DataOutputStream(c.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"file\";filename=\"" + this.fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
FileInputStream fin = new FileInputStream(imageFile);
int bytesAvailable = fin.available();
int maxBufferSize = 1024;
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[ ] buffer = new byte[bufferSize];
int bytesRead = fin.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
dos.write(buffer, 0, bufferSize);
bytesAvailable = fin.available();
bufferSize = Math.min(bytesAvailable,maxBufferSize);
bytesRead = fin.read(buffer, 0,bufferSize);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
fin.close();
dos.flush();
dos.close();
StringBuilder response = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(c.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
response.append(line);
}
return response.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
}
return null;
}
}
Usage:
new ImageUploader(pictureFile, "sample.jpg"){
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();
}
}.execute("http://example/upload.php");
PHP:
<?php
$file = explode('.', $_FILES['file']['name']);
$ext = $file[count($file) - 1];
$name = substr($_FILES['file']['name'], 0, (strlen($ext) + 1) * -1);
$location = 'images/';
$cntr = 1;
$tmp_name = $name;
if(move_uploaded_file($_FILES['file']['tmp_name'], $location.$tmp_name.'.'.$ext)){
echo "Image was uploaded.";
}else{
echo "Image was not uploaded.";
}
?>

If you have the control over the API endpoint. Then try to implement the POST request to accept multi-part uploading from client side.
On client-side, have something like this to upload the image to API (with Okhttp client)
private static final String IMGUR_CLIENT_ID = "...";
private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");
private final OkHttpClient client = new OkHttpClient();
public void run() throws Exception {
// Use the imgur image upload API as documented at https://api.imgur.com/endpoints/image
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("title", "Square Logo")
.addFormDataPart("image", "logo-square.png",
RequestBody.create(MEDIA_TYPE_PNG, new File("website/static/logo-square.png")))
.build();
Request request = new Request.Builder()
.header("Authorization", "Client-ID " + IMGUR_CLIENT_ID)
.url("https://api.imgur.com/3/image")
.post(requestBody)
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
}

I think problem not with downloading to server. If I understand correctly, you getting image from camera and sending it. Note, that if you using simple request intent, that returns in onActivityResult() - Bitmap Image - this may be point of OutOfMemoryException...
Solution it's use another form on Intent() method, (that can get storage path in his parameters) for getting photo from camera, that doesn't return Bitmap image. But save photo to path, which you specified. And now you can do anything with photo in path, without OutOfMemoryException...
Sample starting correct Intent:
File destination = new File(Environment.getExternalStorageDirectory(),
"image.jpg");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(destination));
startActivityForResult(intent, CAMERA_PICTURE);
Let me know, this helps...

send files(images) from android device to webservice on the server written using REST [closed]

Improve this question
I want to send images from android device to my web application running on server with tomcat. please help me in writing small code for sending image to a REST web service running on Web server. Please provide me the sample code if possible. I am stuck with what method to use. Any help would be greatly appreciated. thanks in advance.
Edit: The answer for this question is as follows
while(it.hasNext()){
File file = new File((new StringBuilder()).append(Environment.getExternalStorageDirectory()).append(File.separator).append("jcms").append(File.separator).append("Customer_").append( customer.getId()).toString());
File[] listOfFiles = file.listFiles();
for(int i=0;i<listOfFiles.length;i++){
JSONObject message = new JSONObject();
File fil=listOfFiles[i];
FileInputStream imageInFile = new FileInputStream(fil);
byte imageData[] = new byte[(int)fil.length()];
imageInFile.read(imageData);
String imageDataString = encodeImage(imageData);
URL url=new URL(ClearCustomersContract.CLEAR_SERVER_URL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestMethod("POST");
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(imageDataString);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(
connection.getInputStream()));
while (in.readLine() != null) {
}
in.close();
}
}
And The REST Webservice on server side is like
#Override
#POST
#Consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_OCTET_STREAM})
#Path("/getData")
public Response getAllTheSyncData(InputStream incomingData) {
StringBuilder sb = new StringBuilder();
try {
BufferedReader in = new BufferedReader(new InputStreamReader(incomingData));
String line = null;
while ((line = in.readLine()) != null) {
sb.append(line);
}
} catch (Exception e) {
System.out.println("Error Parsing: - ");
}
return Response.status(200).entity("Success").build();
}
and this is how we convert the string back to image.
byte[] imageByteArray = decodeImage(jsonObj.get("imageData").toString());
imageOutFile = new FileOutputStream(
"C:/Users/SUNILKUMAR/Desktop/result.jpg");
// Write a image byte array into file system
imageOutFile.write(imageByteArray);
imageOutFile.close();

You can use below code to upload image with REST webservice
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(
"YOUR WEB SERVICE URL");
entity = getMultipleEntityUpload();
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost,
httpContext);
HttpEntity httpEntity = httpResponse.getEntity();
InputStream is = httpEntity.getContent();
String line = "";
StringBuilder total = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(
is));
while ((line = rd.readLine()) != null) {
total.append(line);
}
String result =total.toString();
} catch (Exception e) {
// TODO: handle exception
}
private MultipartEntity getMultipleEntityUpload() {
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
try {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
//imagePic is bitmap of your image
imagePic.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] arrByteImage = stream.toByteArray();
try {
entity.addPart(WS_Key_Constant.KEY_IMAGE, new ByteArrayBody(
arrByteImage, ".jpg"));
} catch (Exception e) {
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return entity;

Uploading Files using PHP Script to Web Hosting

I have written out a program which is designed to upload text files created from motion data information to a PHP cloud server that I have set up with 000webhost.com. Ive tried running it however it will not run for some reason. None of the sensor information is uploaded and there seems to be a problem me thinks on the server end. Is the error in the script or code? (or both?).
Edit: Yeah I know its not "great", I am still fairly new to coding and been trying to fiddle around with the code for a while (still working on it).

Just quickly glancing through the code, I believe your problem is here:
upLoadServerUri = "motionsense.uphero.com/public_html/motiondata/UploadToServer.php";
Basically you're trying to make a connection to UploadToServer.php through this public_html directory, however, this directory doesn't exist publically (it's where your "root" files are served from when accessing a website with '/'). Change to:
upLoadServerUri = "motionsense.uphero.com/motiondata/UploadToServer.php";
And you should be fine (assuming everything else works haha).

Failed to upload a file to web service

I have a web service that get a audio and do some operation on it and finally returns a string ,this web service have a web page like this
<form name="form1" method="post" action="Default.aspx" id="form1" enctype="multipart/form-data">
<input type="file" name="FileUpload3" id="FileUpload3" style="width:325px;" />
<input type="submit" name="Button6" value="Upload File" id="Button6" />
<span id="Label1"></span>
</form>
when file choose for uploadfile3 and press upload file a same page should be reload and then show the string in span lable, I want to connect this web service by android so I tried below code to connect and upload file, the server response 200 code but no file uploads to server and no string shows, it seems that server press upload file without choosing file, what can I do? help please.

and my php server side code is as follows
<?php
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
}
else{
echo "There was an error uploading the file, please try again!";
}
?>
Apache is running. When i run server, this error msg appears There was an error uploading the file, please try again!. I have checked the log data in eclipse and what i think is the socket problem but i am not sure. Please help if anyone knows the solution.

It seems that the server is not responding to the client. Try uploading using an ftp connection through the Android application, if that works then check your Apache configuration on accepting connections and the writable directories. When I had a similar problem it turned out that my directory gave no write privileges.
Is the error from Java or from Apache?

Change your code in the following way for the correct escape sequences:
Replace
String lineEnd = "rn";
with
String lineEnd = "\r\n";
