Code:
String recipeName = this.recipe.getName().replace(" ", "%20");;
String recipeIngredients = this.recipe.getIngredients().replace(" ", "%20");;
String recipeInstructions = this.recipe.getInstructions().replace(" ", "%20");;
String recipeUserName = this.recipe.getUserName().replace(" ", "%20");;
int recipeRate = this.recipe.getRate();
int recipeAmountOfRate = this.recipe.getAmountOfRates();
String link = "http://***My_Site***/createRecipe.php?recipeName="+recipeName+"&recipeIngredients="+recipeIngredients
+"&recipeInstructions="+recipeInstructions+"&recipeUserName="+recipeUserName+"&recipeRate="+recipeRate+
"&recipeAmountOfRate="+recipeAmountOfRate;
URL url = new URL(link);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setChunkedStreamingMode(0);
try {
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
int ch;
StringBuffer sb = new StringBuffer();
while ((ch = in.read()) != -1) {
sb.append((char) ch);
}
Log.e("Error", sb.toString());
} catch(Exception e) {
Log.e("Error", e.toString());
} finally {
urlConnection.disconnect();
}
}
But i get the error:
E/Error: java.io.EOFException
Why is that?
in previous requests the request went good.
Doed the URL request too long?

I am creating a translator app where I am getting the input text from android supported voice Recognizer. Example : Hindi, Chinese, etc. Now I want to build the query like this -
public JSONObject getTranslatedText() {
StringBuilder sb = new StringBuilder();
String http = "https://translation.googleapis.com/language/translate/v2?key=xyz";
JSONObject response = null;
String json = "";
HttpURLConnection urlConnection = null;
try {
URL url = new URL(http);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.connect();
String line1 = "{\n" + " 'q': '" + inputString + "',\n" + " 'target': '" + targetcodeString + "'\n" + "}";
DataOutputStream out = new DataOutputStream(urlConnection.getOutputStream());
out.writeBytes(line1);
out.flush();
out.close();
BufferedReader br = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
json = sb.toString();
response = new JSONObject(json);
} catch (MalformedURLException e) {
} catch (IOException e) {
} catch (JSONException e) {
} finally {
if (urlConnection != null) urlConnection.disconnect();
}
return response;
}
The problem is it is not encoding properly and I am getting output like this -
Example: For a word "How are you" in Hindi i.e "क्या हाल" as 9 & HG 08 * E
Can I get some help please. Thanks in advance.
Try using Html.fromHtml(yourTranslatedStr).toString().
I tried that with Hindi and it worked.

I'm essentially trying to mimic what's been done here through the Android app but for some reason data doesn't get returned as soon as it attempts to post data (it returns fine when I delete the writer.write(finalResult) line).
All I want right now is to be able to search for a user's data once I've sent the username.
Here's my code below:
try {
URL u = new URL(url);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("POST");
c.setRequestProperty("Content-length", "0");
c.setConnectTimeout(timeout);
c.setReadTimeout(timeout);
c.setDoInput(true);
c.setDoOutput(true);
//Attempting to send data!
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", paramValue));
OutputStream os = c.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
String finalResult = getQuery(params);
Log.d("params", finalResult);
writer.write(finalResult);
writer.close();
os.close();
c.connect();
int status = c.getResponseCode();
switch (status) {
case 200:
case 201:
BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line+"\n");
}
br.close();
result = sb.toString();
}
} catch (MalformedURLException ex) {
Log.e("log_tag", "Error converting result ");
} catch (IOException ex) {
Log.e("log_tag", "Error in http connection ");
}
//json code!
//parse json data
try{
JSONArray jArray = new JSONArray(result);
//for each object in our json array
for(int i =0; i < jArray.length(); i++){
JSONObject json_data =jArray.getJSONObject(i);
String address = "";
//Checks for missing data in address - Need a class for all fields
if (json_data.isNull("address")){
address = "N/A";
}
else
{
address = json_data.getString("address");;
}
//read one line of the response
myListView.setText("Username: "+json_data.getString("username")
+" / " + "Name: " + json_data.getString("name")
+" / " + "E-mail: " + json_data.getString("email")
+" / " + "Address: " + address);
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data"+e.toString());
}
}
private String getQuery(List<NameValuePair> params) throws UnsupportedEncodingException
{
StringBuilder result = new StringBuilder();
boolean first = true;
for (NameValuePair pair : params)
{
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
}
return result.toString();
}
And here is my php script:
<?php
$searchuser = $_GET["username"];
$databasehost = databasehost;
$databasename = database;
$databaseusername = username;
$databasepassword = password;
$con = mysql_connect($databasehost, $databaseusername, $databasepassword) or die(mysql_error());
mysql_select_db($databasename) or die(mysql_error());
$query = "SELECT * FROM testusers";
$sth = mysql_query($query);
if (mysql_errno()) {
header("HTTP/1.1 500 Internal Server Error");
echo $query."\n";
echo mysql_error();
}
else
{
$rows = array();
while ($r = mysql_fetch_assoc($sth)){
$rows[] = $r;
}
print json_encode($rows);
}
?>
Since you set the header Content-Length to be 0, the server doesn't even read your content... So anything you send isn't received. You should set Content-Length to finalResult.length().
remove this,
c.setRequestProperty("Content-length", "0");
