Since org.appache is deprecated in Android 5.1.1 , and they suggest to use HttpUrlConnection .
Could you help me to change my code this , with valid HttUrlConnection command (im new in Android)
package com.example.cbmedandroid;
import java.io.IOException;
import java.io.InputStream;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;

import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity implements OnClickListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.my_button).setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(false);
new LongRunningGetIO().execute();
}
private class LongRunningGetIO extends AsyncTask <Void, Void, String> {
protected String getASCIIContentFromEntity(HttpEntity entity) throws IllegalStateException, IOException {
InputStream in = entity.getContent();
StringBuffer out = new StringBuffer();
int n = 1;
while (n>0) {
byte[] b = new byte[4096];
n = in.read(b);
if (n>0) out.append(new String(b, 0, n));
}
return out.toString();
}
#Override
protected String doInBackground(Void... params) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://192.168.43.13:8000/api/horaire.json");
String text = null;
try {
HttpResponse response = httpClient.execute(httpGet, localContext);
HttpEntity entity = response.getEntity();
text = getASCIIContentFromEntity(entity);
} catch (Exception e) {
return e.getLocalizedMessage();
}
return text;
}
protected void onPostExecute(String results) {
if (results!=null) {
EditText et = (EditText)findViewById(R.id.my_edit);
et.setText(results);
}
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(true);
}
}
}
Thanks
Also , getASCIIContentFromEntity(HttpEntity entity) seems to be deprecated to !
EDIT : This is what i have changed in my code .
protected String doInBackground(Void... params) {
URL url;
HttpURLConnection urlConnection = null;
try {
url = new URL("http://192.168.43.13:8000/api/horaire.json");
urlConnection = (HttpURLConnection) url.openConnection();
InputStream in = urlConnection.getInputStream();
InputStreamReader isw = new InputStreamReader(in);
int data = isw.read();
while (data != -1) {
char current = (char) data;
data = isw.read();
System.out.print(current);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
}
But what about the "LongRunningGetIO extends AsyncTask " method ?
a HttpGet request without setting anything (like an Accept: application/json header, choosing an encoding, ...) should be fairly equivalent to this:
#Override
protected String doInBackground(Void... params) {
return get("http://192.168.43.13:8000/api/horaire.json");
}
private String get(String urlString) {
try {
HttpURLConnection urlConnection = (HttpURLConnection) new URL(urlString).openConnection();
Reader reader = new InputStreamReader(urlConnection.getInputStream());
try {
StringWriter writer = new StringWriter();
char[] cbuf = new char[8192];
int read;
while ((read = reader.read(cbuf)) != -1) {
writer.write(cbuf, 0, read);
}
return writer.toString();
} finally {
reader.close();
}
} catch (Exception e) {
return e.getMessage();
}
}
Try This
#Override
protected String doInBackground(Void... params) {
StringBuffer response_string = new StringBuffer();
try {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
con.setRequestMethod("POST");
OutputStream os = con.getOutputStream();
os.write(params.toString().getBytes("UTF-8"));
os.close();
int responseCode = con.getResponseCode();
System.out.println("PostParseURL "+url);
System.out.println("PostParseCODE " + responseCode);
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
response_string.append(inputLine);
}
in.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return response_string.toString();
}
and yes there are no need to getASCIIContentFromEntity method and here params are the Your JSONObject request
i was make two file one is mainActivity and second is MultipartEntity
i post both file

Try this simple code in your android, it works for me,
String url = "";// URL where image has to be uploaded
String fileName = ""; //path of file to be uploaded
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
FileBody fileContent = new FiSystem.out.println("hello");
StringBody comment = new StringBody("Filename: " + fileName);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("file", fileContent);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
Hope this helps you with your problem...!!!!!
I have a server made in python that reads the querystring-message and stores it in a sqlite database, and then displays the content.
Now I want to send the message from a android application. This is my code so far.
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import android.R.string;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity {
Button send;
TextView display;
String message;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
send = (Button)findViewById(R.id.button1);
display = (TextView)findViewById(R.id.editText1);
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try{
post();
}
catch(Exception e)
{
display.setText("Det sket sig");
}
}
public void post() throws UnsupportedEncodingException
{
message = display.getText().toString();
String data = URLEncoder.encode("?message", "UTF-8")

String text = "";
BufferedReader reader=null;
try
{
URL url = new URL("http:homepage.net");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));

while((line = reader.readLine()) != null)
{

}
text = sb.toString();
}
catch(Exception e)

}
finally
{
try

}
catch(Exception ex) {}
}
display.setText(text);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
This is not functioning as per the expectations. What am i doing wrong here?
for network related operation you have to use asynctask or thread other wise you wil get NetworkOnMainThread Exception.
refer here
private class MyTask extends AsyncTask<Void, Void, Void> { ... }
Use following AsyncTask to make server request:
public class RestServiceTask extends AsyncTask<String, Void, String> {
private String errorMessage;
public RestServiceTask() {
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected String doInBackground(String... params) {
String url = params[1];
String method = params[2];
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 60000);
HttpConnectionParams.setSoTimeout(httpParameters, 60000);
HttpClient client = new DefaultHttpClient(httpParameters);
HttpUriRequest request;
try {
if (method.equals("get")) {
request = new HttpGet(url);
} else {
request = new HttpPost(url);
if (params.length > 0 && params[0] != null) {
StringEntity entity = new StringEntity(params[0]);
((HttpPost) request).setEntity(entity);
Crashlytics.log(Log.INFO, "Request", params[0]);
}
((HttpPost) request).setHeader("Content-Type",
"application/json");
}
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
String json = convertStreamToString(entity.getContent());
Crashlytics.log(Log.INFO, "Response", json);
return json;
} catch (Exception e) {
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
//process your result
}
public String convertStreamToString(InputStream is) throws IOException {
if (is != null) {
Writer writer = new StringWriter();
char[] buffer = new char[1024];
try {
Reader reader = new BufferedReader(new InputStreamReader(is,
"UTF-8"));
int n;
while ((n = reader.read(buffer)) != -1) {
writer.write(buffer, 0, n);
}
} finally {
is.close();
}
return writer.toString();
} else {
return "";
}
}
}
Use it by:
new RestServiceTask().execute("<json string>",url,method);//method can be get,post
try this simple example if you have any doubt follow this links:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.codeincloud.tk/First.php");
try {
HttpResponse response = httpclient.execute(httppost);
final String str = EntityUtils.toString(response.getEntity());
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText(str);
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

You should change the title of your question, there is no such thing as queryString in a POST. Query String parameters only gets added in a GET, and in POST you pass data in the body of the request.
Also, you could use this in combination with AsyncTask to solve your problem
EDIT: Also, Check here for more about GET and POST
Try this :
HttpParams params = new BasicHttpParams();
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpClient httpClient = new DefaultHttpClient(params);
HttpPost httpPost = new HttpPost(your website);
List<NameValuePair> entityParams = new ArrayList<NameValuePair>();
entityParams.add(new BasicNameValuePair("action", "postcomment"));
entityParams.add(new BasicNameValuePair("app_id", com.appbuilder.sdk.android.Statics.appId));
entityParams.add(new BasicNameValuePair("message", message1));
entityParams.add(new BasicNameValuePair("message2", message2));
httpPost.setEntity(new UrlEncodedFormEntity(entityParams, "utf-8"));
String resp = httpClient.execute(httpPost, new BasicResponseHandler());
I want to make an Android app that reads some data from a php page and put it into a textview.
I already tested it yesterday and it worked! but I dont know what i changed so today it wont work..
(I am sure that I dont used async tasks or something like this)
package com.example.test04;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
private String url = "this is the url ";
private TextView textView;
private Thread thread;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById (R.id.textView2);
// runthread();
try{
textView.setText("");
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);
BufferedReader rd = new BufferedReader (new InputStreamReader(response.getEntity().getContent()));
String line ="";
while ((line = rd.readLine()) != null) {
line = line.replace("\\n", "\n");
textView.append(line);
}
} catch (Exception e) {
Log.e("log_tag1234", "Error converting result === " + e.toString());
}
}}
after that I tried it with runOnUiThread but it also dont works
//
// private void runThread() {
//
// new Thread() {
// public void run() {
//
// try {
// runOnUiThread(new Runnable() {
//
// #Override
// public void run() {
// try{
// textView.setText("");
// HttpClient client = new DefaultHttpClient();
// HttpGet request = new HttpGet(url);
// HttpResponse response = client.execute(request);
//
// BufferedReader rd = new BufferedReader (new InputStreamReader(response.getEntity().getContent()));
//
// String line ="";
// while ((line = rd.readLine()) != null) {
// line = line.replace("\\n", "\n");
// textView.append(line);
//
// }
//
// } catch (Exception e) {
// Log.e("log_tag1234", "Error converting result === " + e.toString());
// }
// }
// });
//
// } catch (Exception e) {
// e.printStackTrace();
// }
//
// }
// }.start();
// }
how can I fix it as easy as possible? why it doesnt work anymore?
Reading Php Json values, Eclipse dont see the error but it doesnt work. Im becoming crazy because it must run, can you help me?
When i execute it nothing happens.
This is the java activity code:

}*/
}
catch (JSONException e) {

}
catch (ClientProtocolException e) {

}
catch (IOException e) {

}
}
private StringBuilder inputStreamToString(InputStream is) {
String rLine = "";
StringBuilder answer = new StringBuilder();

try {
while ((rLine = rd.readLine()) != null) {
answer.append(rLine);
}
}
catch (IOException e) {
e.printStackTrace();
}
return answer;
}
}
and here is the json code into iatek.eu/sys/getsms.php
{"posts":[{"cid":"11","username":"Livi","sms":"ag","fto":"","fcat":"cat"},{"cid":"10","username":"Sumone","sms":"","fto":"","fcat":""},{"cid":"9","username":"R2D2","sms":"dw","fto":"wd","fcat":"wd"},{"cid":"5","username":"Roy","sms":"sa","fto":"sa","fcat":"sa"},{"cid":"12","username":"Charles","sms":"ag","fto":"","fcat":"cat"},{"cid":"13","username":"Clarck","sms":"age","fto":"","fcat":"cat"}]}
can someone tell me where is the mistake?
thanks
You cannot run network operation on the main thread.
Use asyncTask instead.
public class JSONExampleActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new GetSmsTask().execute("http://iatek.eu/sys/getsms.php");
}
private class GetSmsTask extends AsyncTask<String, Void, JSONObject> {
protected JSONObject doInBackground(String... urls) {
JSONObject obj = null;
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url[0]);
HttpResponse response = httpclient.execute(httppost);
String jsonResult = inputStreamToString(response.getEntity()
.getContent()).toString();
obj = new JSONObject(jsonResult);
}
catch (JSONException e) {
e.printStackTrace();
}
catch (ClientProtocolException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
return obj;
}
protected void onPostExecute(JSONObject obj) {
JSONArray jsonArray = obj.getJSONArray("posts");
JSONObject childJSONObject = jsonArray.getJSONObject(3);
String username = childJSONObject.getString("username");
String sms = childJSONObject.getString("sms");
String fcat = childJSONObject.getString("fcat");
textView.setText(""+sms+"--" + username);
}
}
}
EDIT:
I just ran the code myslef, and I got this
09-13 13:33:59.315: W/System.err(14200): org.json.JSONException:
Unterminated object at character 7551 of {"posts":[{......
This means your JSON is invalid
http://pro.jsonlint.com/ paste your link there you will see the error.
To test that the code is working replace this
String jsonResult = inputStreamToString(response.getEntity()
.getContent()).toString();
with this:
String jsonResult = "{\"posts\":" +
"[{\"cid\":\"11\",\"username\":\"Livi\",\"sms\":\"ag\",\"fto\":\"\",\"fcat\":\"cat\"}," +
" {\"cid\":\"11\",\"username\":\"Livi\",\"sms\":\"ag\",\"fto\":\"\",\"fcat\":\"cat\"}, " +
"{\"cid\":\"11\",\"username\":\"Livi\",\"sms\":\"ag\",\"fto\":\"\",\"fcat\":\"cat\"}," +
"{\"cid\":\"11\",\"username\":\"Livi\",\"sms\":\"ag\",\"fto\":\"\",\"fcat\":\"cat\"}]}";
RESOLVED!!!! ALL ITS PERFECT
HERE IS THE CODE
