How can I define an Array of Images and create a for loop for it to add into body of multipart data without LIBRARY?

I have tried to create an array of images looked for examples in treehouse and StackOverflow but many of them telling about creating an array of Int then defining images for the count of this int array.
My problems are first I need to create an array of images second I need to upload them to the server without the library. This array of images should be pass as a parameter to upload function. So that I can upload a single image and multiple images with the same function.

How to upload Less than 1 MB image in Android Using volley library?

I want to check less than 1 MB image and upload to remote server using volley library in Android.....please help me.
For select image I use this code:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),PICK_IMAGE_REQUEST);
In Activity Result I Use:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
try {
if (Build.VERSION.SDK_INT>19){
}else {
Uri filePath = data.getData();
File file = new File(filePath.getPath());
int length = (int) file.length();
double lengthkb = length / 1024;
if (lengthkb > 0.0D) {
lengthmb = lengthkb / 1024;
Log.d("picsize", lengthmb + "");
} else {
File file2 = new File(getPath(filePath));
int length2 = (int) file2.length();
double lengthkb2 = length2 / 1024;
lengthmb = lengthkb2 / 1024;
Log.d("picsize", lengthmb + "");
}
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath); imageViewProfileImage.setImageBitmap(bitmap); }
} catch(IOException e){
e.printStackTrace();
}
}
}

After You pick image from gallery the bellow code in that code you pass parameters and image URL.

How to post data using multipart?

I develop one app. In my app i take one image from camera or one from gallery. I want to post image to server using Multipart but image not post it. My post data is below
{
"suggested_item" :{
"name": "apple",
"description" : "nice apple",
"image": "image.png"
}
}
My java code is
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_FROM_CAMERA) {
try{
if(resultCode == -1){
File file = new File(Environment.getExternalStorageDirectory()+File.separator +"image.png");
bitmap = loadBitmap(file);
iv_pic.setImageBitmap(bitmap);
try {
Uri tempUri = getImageUri(getActivity(), bitmap);
Log.i(TAG,"onActivityResult PICK_FROM_CAMERA, tempUri : "+tempUri);
//uploadFile(tempUri + "" + System.currentTimeMillis()+".png");
} catch (Exception e) {
e.printStackTrace();
}
}else{
//setResult(RESULT_CANCELED);
//Activity.this.finish();
}
}catch(Exception e){
e.printStackTrace();
}
}else if (requestCode == PICK_FROM_GALLERY) {
try{
//Log.i(TAG,"onActivityResult PICK_FROM_GALLERY, data : "+data);
if(data !=null){
bitmap = null;
try {
bitmap = new BitmapDrawable(MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), data.getData())).getBitmap();
iv_pic.setImageBitmap(bitmap);
try {
Uri tempUri = getImageUri(getActivity(), bitmap);
Log.i(TAG,"onActivityResult PICK_FROM_GALLERY, tempUri : "+tempUri);

public Uri getImageUri(Context context , Bitmap bitmap) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG , 100 , bytes);
String path = Images.Media.insertImage(context.getContentResolver() , bitmap , "Title" , null);
return Uri.parse(path);
}
please help me thanks in advance.

To send binary data you need to use addBinaryBody method of MultipartEntityBuilder. Sample of attaching:
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
//Image attaching
MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
File file;
multipartEntity.addBinaryBody("someName", file, ContentType.create("image/jpeg"), file.getName());
//Json string attaching
String json;
multipartEntity.addPart("someName", new StringBody(json, ContentType.TEXT_PLAIN));
Then make request as usual:
HttpPut put = new HttpPut("url");
put.setEntity(multipartEntity.build());
HttpResponse response = client.execute(put);
int statusCode = response.getStatusLine().getStatusCode();

I suggest using retrofit.
Posting multipart will be something like this:
#Multipart
#PUT("user/photo")
Call<User> updateUser(#Part("photo") RequestBody photo, #Part("description") RequestBody description);
Refer to this question for more details.
This is a good tutorial to check if you are not familiar to retrofit.

You are getting the org.json.JSON Exception : End of input at character 0 Because, you got null response which generated that exception.
So, Check your result string before convert in to JSONObject.
JSONObject jobj = new JSONObject(result); // Check this result string.
Again answer for Request.
Haresh Chhelana Answer is correct.
BufferedReader r = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder result = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
result.append(line);
}
JSONObject jobj = new JSONObject(result.toString());
Thanks.

Try to use BufferedReader :
BufferedReader r = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder result = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
result.append(line);
}

Uploading an image to a server in Android app

In my app I am capturing an image and uploading it to the server. The capturing and uploading part works fine in my Android device which is of 5 mega pixel.
But the app crashes occasionally when taking a photo. We've noticed if someone takes a
picture that has a high megapixel setting, the photo does not upload and the app crashes.
How to reduce the size of a 8 megapixel photo to be able to upload without crashing?
Do I have to compress the captured image. Following is my code to capture an image
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE,fileName);
mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.ACTION_IMAGE_CAPTURE, capturedImage);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
startActivityForResult(intent, 3);
I am uploading the image in OnActivity Result as follows
public void onActivityResult(int requestCode, int resultCode, final Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 3)
{
String[] projection = { MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(mCapturedImageURI, projection, null, null, null);
int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
capturedImage = cursor.getString(column_index_data);
String url = "http://xxxxxxxxxxxxxx.com/device_upload.php";
new ProfileAddImageFileAsync().execute(url);
}
}
And I am running a progress dialog box until the upload get completed, as follows
class ProfileAddImageFileAsync extends AsyncTask<String, String, String>
{
#Override
protected void onPreExecute()
{
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
protected String doInBackground(String... Aurl)
{
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inStream = null;
try
{
URL urlServer = new URL(aurl[0]);
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
int maxBufferSize = 1*1024*1024;
FileInputStream fileInputStream = new FileInputStream(new File(capturedImage) );
connection = (HttpURLConnection) urlServer.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
outputStream = new
DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"userfile\";filename=\"" + capturedImage +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
Log.e("bytesAvailable ",""+bytesAvailable);
bufferSize = Math.min(bytesAvailable, maxBufferSize);
Log.e("bufferSize ",""+bufferSize);
byte[] buffer = new byte[bufferSize];
Log.e("bufer ",""+buffer);
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);

Please help me friends, the above code is my working code in my 5MP camera.

i got solution like this, i use to capture and compress the image.
Following is my camera part
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory(), String.valueOf(System.currentTimeMillis()) + ".jpg");
Log.e("ffffffffffiiiiiiiiilllllllllle ",""+file);
f = String.valueOf(file);
mCapturedImageURI = Uri.fromFile(file);
Log.e("outputFileUri ",""+mCapturedImageURI);
setupImage(intent);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
startActivityForResult(intent, 3);
i am uploading the image in OnActivity Result as follows
public void onActivityResult(int requestCode, int resultCode, final Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 3)
{
capturedImage = f;
String url = "http://xxxxxxxxxxxxxx.com/device_upload.php";
new ProfileAddImageFileAsync().execute(url);
}
}
