How do I load an image using the Volley library?
I have an image and I want to upload this image to my webservice using Volley library, the problem is I am looking for how to do this but still cannot find it.
I found this but doesn't work for me: http://develop-for-android.blogspot.com.br/2014/01/using-volley-in-your-application.html
How can i do this?
I am trying to do this.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
fotoPerfil = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
UploadoImageToServer upload = new UploadoImageToServer();
ApplicationController app = new UsuarioDAO().insert(usuario, upload.upload(fotoPerfil, em[0]), new UsuarioAdapter(){
@Override
public void usuarioIsAdded(Boolean result){
Log.i("Adicionou: ", result + "");
progress.dismiss();
}
});
CustomVolleySingleton.getInstance(getApplicationContext()).addToRequestQueue(app);
public class UploadoImageToServer {
public String upload(String image,String nomeImagem){
Bitmap bitmap = BitmapFactory.decodeFile(image);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
return image_str;
}
}
/** add an user and upload your foto(image) */
public ApplicationController insert(Usuario u, String uploadFile, final UsuarioAdapter listener) {
boolean insert = false;
HashMap<String, String> params = new HashMap<String, String>();
params.put("nome", u.getNome());
params.put("email", u.getEmail());
params.put("senha", u.getSenha());
params.put("tipo", "usuarios");
params.put("acao", "add");
params.put("device_tipo", "android");
params.put("device", AndroidReturnId.getAndroidId());
params.put("uploadedfile", uploadFile);
Log.i("URL: ", urlPost.toString());
ApplicationController apc = new ApplicationController(Method.POST, urlPost.toString(), params,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject obj) {
try {
if(obj.getString("cod").equals("999")){
listener.usuarioIsAdded(true);
}else{
listener.usuarioIsAdded(false);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError arg0) {
Log.e("ERROR METHOD:", "insert in UsuarioDAO: " + arg0.getLocalizedMessage());
}
});
return apc;
}

I'm not that much familier with a salvo, but try the following code
// JSON request
public MySampleImageUpload() {
JSONRequestResponse mResponse = new
JSONRequestResponse(mContext);
Bundle parms = new Bundle();
parms.putString("key_meail", "rojesh@demo.com");
parms.setFile("key_url", image_path);
mResponse.getResponse("sample_upload_data_url", REQUEST_CODE, this,
parms);
}
// In the code, SetFile and getResponse
package com.fartogram.utils;
import java.io.File;
import org.json.JSONObject;
import android.content.Context;
import android.os.Bundle;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.examples.toolbox.MultipartRequest;
import com.android.volley.examples.toolbox.MyVolley;
import com.android.volley.toolbox.JsonObjectRequest;
public class JSONRequestResponse {
public JSONRequestResponse(Context cntx) {
mContext = cntx;
}
private final Context mContext;
private int reqCode;
private IParseListener listner;
private boolean isFile = false;
private String file_path = "", key = "";
public void getResponse(String url, final int requestCode,
IParseListener mParseListener) {
getResponse(url, requestCode, mParseListener, null);
}
public void getResponse(String url, final int requestCode,
IParseListener mParseListener, Bundle params) {
this.listner = mParseListener;
this.reqCode = requestCode;
Response.Listener<JSONObject> sListener = new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
if (listner != null) {
listner.SuccessResponse(response, reqCode);
}
}
};
Response.ErrorListener eListener = new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
if (listner != null) {
listner.ErrorResponse(error, reqCode);
}
}
};
if (!isFile) {
JsonObjectRequest jsObjRequest = new JsonObjectRequest(
Request.Method.GET, url, null, sListener,
eListener);
MyVolley.getRequestQueue().add(jsObjRequest);
} else {
if (file_path != null) {
File mFile = new File(file_path);
MultipartRequest multipartRequest =
new MultipartRequest(url,eListener, sListener, key, mFile, params);
MyVolley.getRequestQueue().add(multipartRequest);
}
}
}
public boolean isFile() {
return isFile;
}
public void setFile(String param, String path) {
if (path != null && param != null) {
key = param;
file_path = path;
this.isFile = true;
}
}
}
If it works for you, please mark it as correct :)

You need to extend the query and use MultipartEntityBuilder if you want to upload the image as a file.
public class ImageUploadWithVolley<T> extends Request<T> {
private MultipartEntityBuilder mBuilder = MultipartEntityBuilder.create();
private final Response.Listener<T> mListener;
private final File yourImageFile;
protected Map<String, String> headers;
public ImageUploadWithVolley(String url, ErrorListener errorListener, Listener<T> listener, File imageFile) {
super(Method.POST, url, errorListener);
mListener = listener;
yourImageFile = imageFile;
addImageEntity();
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = super.getHeaders();
if (headers == null
|| headers.equals(Collections.emptyMap())) {
headers = new HashMap<String, String>();
}
headers.put("Accept", "application/json");
return headers;
}
private void addImageEntity() {
mBuilder.addBinaryBody("give your image name", yourImageFile, ContentType.create("image/jpeg"), yourImageFile.getName());
mBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
mBuilder.setLaxMode().setBoundary("xx").setCharset(Charset.forName("UTF-8"));
}
@Override
public String getBodyContentType() {
String content = mBuilder.build().getContentType().getValue();
return content;
}
@Override
public byte[] getBody() throws AuthFailureError {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
mBuilder.build().writeTo(bos);
} catch (IOException e){
VolleyLog.e("IOException writing to ByteArrayOutputStream bos, building the multipart request.");
}
return bos.toByteArray();
}
@Override
protected Response<T> parseNetworkResponse(NetworkResponse response){
T result = null;
return Response.success(result, HttpHeaderParser.parseCacheHeaders(response));
}
@Override
protected void deliverResponse(T response) {
mListener.onResponse(response);
}
}
