I am trying to send an image to our asp.net webservice from android.Here is my sample code :
// Getting image from Gallery
Code:
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]);
picturePath = cursor.getString(columnIndex);
cursor.close();
/* BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;*/
thumbnail = (BitmapFactory.decodeFile(picturePath));
img_photo.setImageBitmap(thumbnail);
// converting imag into base64 string
Code:
img_photo.buildDrawingCache();
Bitmap bm = img_photo.getDrawingCache();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG, 100, baos); // bm is the bitmap
byte[] photo = baos.toByteArray();
System.out.println("this is byte array" + bytearray);
String temp_base =Base64.encodeToString(photo,Base64.NO_WRAP);
// calling webservice
Code:
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("CarID", SellCarDetailView.sellcardetails_carid);
request.addProperty("pic",temp_base);
System.out.println("this is piccontent" +temp_base);
try {
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
soapEnvelope.encodingStyle = SoapEnvelope.ENC;
// new MarshalBase64().register(soapEnvelope);
soapEnvelope.dotNet = true;
soapEnvelope.setOutputSoapObject(request);
HttpTransportSE aht = new HttpTransportSE(URL);
//AndroidHttpTransport aht = new AndroidHttpTransport(URL);
aht.call(SOAP_ACTION, soapEnvelope);
// SoapObject response = (SoapObject)envelope.getResponse();
SoapPrimitive response = (SoapPrimitive) soapEnvelope.getResponse();
String temp3 = response.toString();
Log.v("TAG", temp3);
} catch (Exception e) {
e.printStackTrace();
}
How ever i am getting "invalid parameter" at web service end.
// Asp.net code
Code:
[ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Xml)]
[WebMethod(EnableSession = true)]
public string UploadPictureByCarIDFromAndroid(string CarID, string make, string model, string year, string UserID, string pic, string AuthenticationID, string CustomerID, string SessionID)
{
string bStatus = "Failed";
MobileBL objMobile = new MobileBL();
UsedCarsInfo objCarPicInfo = new UsedCarsInfo();
try
{
try
{
if (AuthenticationID == ConfigurationManager.AppSettings["AppleID"].ToString())
{
objCarPicInfo.Carid = Convert.ToInt32(CarID);
byte[] picContent = Convert.FromBase64String(pic);
// byte[] picContent = Base64.decode(pic);
MemoryStream ms = new MemoryStream(picContent, 0,picContent.Length); // getting "invalid length"
ms.Write(picContent, 0, picContent.Length);
Bitmap oBitmap1 = new Bitmap(ms);// getting "invalid length" error here
// System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
}
}
catch (Exception ex)
{
}
}
catch (Exception ex)
{
}
return bStatus;
}
I am getting "invalid length" error when sending the image.Any help is highly appreciated.
i think a better approach is with stream rather file path
for example you can try
Get image from gallery
Code:
Uri selectedImage = data.getData();
BitmapFactory.Options options = new BitmapFactory.Options();
//your options
Bitmap img_photo = BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, options);
convert to base64
Code:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
img_photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
String temp_base =Base64.encodeToString(byteArray,Base64.DEFAULT);
i cant see anything wrong in the web services call but shouldn't you send all the parameters the function needs?
also, try to change this
Code:
// SoapObject response = (SoapObject)envelope.getResponse();
SoapPrimitive response = (SoapPrimitive) soapEnvelope.getResponse();
String temp3 = response.toString();
to this
Code:
SoapObject response = (SoapObject)envelope.getResponse();
String temp3 = response.getProperty(0).toString();

Thanks for giving reply, i tried your code but getting the same problem.
sending to web service is ok?
trying this in the web service end?
Code:
Bitmap bmpReturn = null;
byte[] byteBuffer = Convert.FromBase64String(base64String);
MemoryStream memoryStream = new MemoryStream(byteBuffer);
memoryStream.Position = 0;
bmpReturn = (Bitmap)Bitmap.FromStream(memoryStream);
memoryStream.Close();
memoryStream = null;
byteBuffer = null;

This is called varargs. The ... In the doInBackground method say that you can receive any number of arguments of a type. In this case string. Inside the method they are used like arrays.

I can't populate database in android 4.4 using phonegap when I run my app the first time, but if I close the app and open it again this task works fine.
I have a 0000000000000001.db in assets and I want put this in Android 4.4 memory.
How can I deal with such Issue?
I'm using this code to populate the database in Android 4.4 memory

//DB_PATH3 = "/data/data/com.example.testapp/app_webview/databases/file__0/";
//DB_NAME3 = "1";

I am new to Java and I am getting kind of stuck by trying to loop through my JSON. I am retrieving a JSON object where I want to loop through.
My JSON looks as follow:
Code:
{"message":{"2":[{"uid":"2","title":"","message":"Test1","success":1,"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !","success":1,"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","success":1,"created_at":null,"updated_at":null}]}}
I tried a loop like this:
Code:
for(int i = 0; i<json.names().length(); i++){
try {
Log.v("TEST", "key = " + json.names().getString(i) + " value = " + json.get(json.names().getString(i)));
} catch (JSONException e) {
e.printStackTrace();
}
}
But this will only target "message" which includes the whole JSON "string". I want to loop through each message and retrieving the value of uid 1, uid 2 etc. How can I achieve this?
Thanks in advance.
Here is how I'm doing it:
Code:
private static final String AllNewsItemsURL = "some_url_here.php";
private static final String TAG_SUCCESS = "success";
private static final String NEWS = "news";
private static final String TITLE = "title";
private static final String STORY = "story";
private final JSONParser jParser = new JSONParser();
private JSONArray newsItems = null;
..... / code snipped / ....
try {
JSONObject json = jParser.makeHttpRequest(AllNewsItemsURL, params);
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
newsItems = json.getJSONArray(NEWS);
for (int i = 0; i < newsItems.length(); i++) {
JSONObject obj = newsItems.getJSONObject(i);
Integer id = i + 1;
String title = obj.getString(TITLE);
String story = obj.getString(STORY);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}
Thanks for your reply. I tried it but getting this exception:
Code:
org.json.JSONException: Value {"2":[{"uid":"2","title":"","message":"Test1","success":1,"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2","success":1,"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3","success":1,"created_at":null,"updated_at":null}]} at messages of type org.json.JSONObject cannot be converted to JSONArray

You might want to try the matching JSONParser I have for it, sorry forgot to include it:
https://github.com/JonnyXDA/WGSB/bl...om/jonny/wgsb/material/parser/JSONParser.java
Also noting that your entire JSON Array is called "message" but you also have a parameter called "message" - maybe rename the Array to "messages"?
As for the code you should have something like:
Code:
private static final String AllNewsItemsURL = "some_url_here.php";
private static final String TAG_SUCCESS = "success";
private static final String MESSAGES = "messages";
private static final String TITLE = "title";
private static final String MESSAGE = "message";
private final JSONParser jParser = new JSONParser();
private JSONArray messageItems = null;
..... / code snipped / ....
try {
JSONObject json = jParser.makeHttpRequest(AllNewsItemsURL, params);
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}
My code looks like the this:
Code:
//Message task
MessageTask task = new MessageTask(DashboardActivity.class);
task.execute();
try {
json = task.get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}
I am using Async Task to retrieve my JSON.
And my JSON parser looks like this:
Code:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
But it doesn't get through the if statement, because it can't find the value success. ( org.json.JSONException: No value for success ). Don't really know what I am doing wrong here. Is it because I am using AsyncTask and retrieving my JSON the wrong way?
I also renamed my Array to "messages", stupid mistake thanks!

We're getting closer! With regards to using AsyncTask - thats fine and the recommended way to do service side sync/download operations (doesn't block the UI thread) so no need to change that.
I just took a look at my reference JSON and I have the success tag outside of an item eg:
Code:
{"topical":[{"tid":"5","title":"Exam countdown... just 12 weeks left!","story":"some_story_text_here","staff":"0","red":"0","show":"1"}],[COLOR="red"]"success":1[/COLOR]}
Whereas your success tag is put in each item:
Code:
{"message":{"2":[{"uid":"2","title":"","message":"Test1","[COLOR="red"]success":1,[/COLOR]"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !",[COLOR="red"]"success":1[/COLOR],"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","[COLOR="Red"]success":1[/COLOR],"created_at":null,"updated_at":null}]}}
I'm guessing that your php line for:
PHP:
$response["success"] = 1;
is inside of the while loop:
PHP:
while ($row = mysql_fetch_array($result)) {
Taking it out of the while loop should fix that
That makes sense, because I am trying to get a success code for my whole JSON response. I changed my PHP code to:
Code:
while($row = mysqli_fetch_array( $messages )) {
// create rowArr
$rowArr = array(
'uid' => $row['id'],
'title' => $row['title'],
'message' => $row["message"],
'created_at' => $row['created_at'],
'updated_at' => $row['updated_at'],
);
// store rowArr in $return_arr
$return_arr[$row['id']][] = $rowArr;
}
$return_arr['success'] = 1;
// Json encode
echo json_encode(array("messages" => $return_arr));
}
Retrieving the following JSON:
Code:
{"messages":{"2":[{"uid":"2","title":"","message":"Test1","created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !","created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","created_at":null,"updated_at":null}],"success":1}}
But I am still getting the following exception:
Code:
org.json.JSONException: No value for success
The success tag is still being encoded as part of an inner array, not the first array - try this:
PHP:
if (mysql_num_rows($messages) > 0) {
$response["messages"] = array();
while ($row = mysql_fetch_array($messages)) {
$messagesArray= array(
'uid' => $row['id'],
'title' => $row['title'],
'message' => $row['message'],
'created_at' => $row['created_at'],
'updated_at' => $row['updated_at'],
);
array_push($response["messages"], $messagesArray);
}
$response["success"] = 1;
echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "No messages found";
echo json_encode($response);
}
And it's finally working!
Getting the following JSON result:
Code:
{"tag":"message","success":1,"error":0,"messages":[{"uid":"2","title":"","message":"Test1","created_at":null,"updated_at":null},{"uid":"3","title":"","message":"Test2!","created_at":null,"updated_at":null},{"uid":"4","title":"Bla","message":"Test3!","created_at":null,"updated_at":null}]}
And I can successfully loop through my JSON with the following code:
Code:
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
Log.e("TITLE :", title);

Thank you very much! So the problem was that I placed the "success" tag outside my Array?
( Volley > sending GET Request with parameters ) How to flatten Map<String,String> pa
I got this custom volley request class that extends Request with the request parameters in Map<String,String> format, my question is how to flatten Map<String,String> parameters correctly into a query string and receive it with PHP $_GET?
Code:
public class GsonGetRequest_Exp5<T> extends Request<T> {
private Response.Listener<T> listener;
private Map<String, String> params;
private Type type;
private Gson gson;
public GsonGetRequest_Exp5(String url, Map<String, String> params, Type type, Gson gson,
Response.Listener<T> reponseListener, Response.ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.type = type;
this.gson = gson;
this.listener = reponseListener;
this.params = params;
}
public GsonGetRequest_Exp5(int method, String url, Map<String, String> params, Type type, Gson gson,
Response.Listener<T> reponseListener, Response.ErrorListener errorListener) {
super(method, url, errorListener);
this.type = type;
this.gson = gson;
this.listener = reponseListener;
this.params = params;
}
@Override
protected Map<String, String> getParams() throws com.android.volley.AuthFailureError {
return params;
};
@Override
protected void deliverResponse(T response) {
listener.onResponse(response);
}
@Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return (Response<T>) Response.success
(
gson.fromJson(jsonString, type),
HttpHeaderParser.parseCacheHeaders(response)
);
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException je) {
return Response.error(new ParseError(je));
}
}
}
Code:
public static GsonGetRequest_Exp5<ArrayList<FeedObject>> gsonGetRequest_exp6
(
Response.Listener<ArrayList<FeedObject>> listener,
Response.ErrorListener errorListener,
String str
)
{
//final String url = "example.com/php.php";
final Map<String, String> params = new HashMap<String, String>();
final Gson gson = new GsonBuilder()
.registerTypeAdapter(FeedObject.class, new FeedObjectDeserializer())
.create();
String test_url = "example.com/php.php";
params.put("SearchKey", str);
StringBuilder builder = new StringBuilder();
for (String key : params.keySet())
{
Object value = params.get(key);
if (value != null)
{
try
{
value = URLEncoder.encode(String.valueOf(value), HTTP.UTF_8);
if (builder.length() > 0)
builder.append("&");
builder.append(key).append("=").append(value);
}
catch (UnsupportedEncodingException e)
{
}
}
}
test_url += "?" + builder.toString();
return new GsonGetRequest_Exp5
(
test_url,
params,
new TypeToken<ArrayList<FeedObject>>() {}.getType(),
gson,
listener,
errorListener
);
}
problem with my code is, the "params" I keep getting "null", nothing is added to the end of my example.com url, can anyone point out what I did wrong?
