Can't load my data from MySQL even though php code is working?

I am a newer android developer , and i try to make an app which depend on MySQL.
so i have MySQL database and I have A php that return its data in Json format at this link here.
so i make a simple app that take this data and show it in list view by AsyncTask & Service Handler .
Note 1: I try this app with another database [Not Free Domain/website] and it work But with my database didn't work [free hosting]
Note 2: I try to comment the "Try & Catch" code at doInBackground method at AsyncTask class & make a dummy data manually So the app works !!, so what???!!
Update: i used the emulator and i got some red massages that i do not understand what its mean so i take it as screen shot
My php code:
<?php
$dbname = 'zoubg_18363398_center';
$dbserver = 'sql104.kariya-host.com';
$dbusername = 'zoubg_18363398';
$dbpassword = '28721235';
$dbconnect = new mysqli($dbserver, $dbusername, $dbpassword, $dbname);
$getpostssql = "SELECT * FROM users";
$posts = $dbconnect->query($getpostssql);
$postsarray = array();
while($row = mysqli_fetch_array($posts, MYSQL_ASSOC)){
$temp['id'] = $row['id'];
$temp['name'] = $row['name'];
$temp['password'] = $row['password'];
$temp['email'] = $row['email'];
$temp['adress'] = $row['adress'];
array_push($postsarray, $temp);
}
echo json_encode(array("posts"=>$postsarray), JSON_UNESCAPED_UNICODE);

update: every thing was right, problem was in hosting server when i change hosting server , every thing work probably Thanks for interresting

Java Interface Callback on Android

I am currently trying to make an android app that basically downloads strings from a url. But I want to make it object oriented. My mainActivity gets string from webService which downloads string when button is clicked. But I am not good at interfaces and callbacks. What should I do to make this code run?
public class MainActivity extends Activity implements WebServiceInterface{
private TextView textView;
private Button readWebPage;
private WebService service;
private WebServiceInterface webServiceInterface;
private String response;
/**
* Called when the activity is first created.
*/
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.TextView01);
readWebPage = (Button) findViewById(R.id.readWebpage);
service = new WebService();
readWebPage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
service.execute(new String[]{"http://google.com/"});
onSuccess(response);
}
});
}
#Override
public void onSuccess(String response) {
textView.setText(Html.fromHtml(response));
}
#Override
public void onFail(Exception ex) {
textView.setText(ex.getLocalizedMessage());
}
}
public class WebService extends AsyncTask<String, Void, String> {
private WebServiceInterface webServiceInterface;
#Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
webServiceInterface.onSuccess(response);
} catch (Exception e) {
e.printStackTrace();
webServiceInterface.onFail(e);
}
}
return response;
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
}
}
public interface WebServiceInterface {
void onSuccess(String response);
void onFail(Exception ex);
}

you need to create one public method for set webServiceInterface in WebService class like
public setWebServiceInterface (WebServiceInterface listener)
{
this.webServiceInterface =listener;
}
in MainActivity activity call this method and pass argument this
service.setWebServiceInterface (this);
in WebService class in onPostExecute Method call
webServiceInterface.onSuccess(s);

Add WebService (WebServiceInterface webServiceInterface) in your AsyncTask as a constructor.
service = new WebService(new WebServiceInterface (){
void onSuccess(String response){
//do your stuff
}
void onFail(Exception ex){
//do your stuff
}
});
and in your asynctask
public class WebService extends AsyncTask<String, Void, String> {
public WebService (WebServiceInterface webServiceInterface){
this.webinterface= webServiceInterface;
}
private WebServiceInterface webinterface;
#Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
webinterface.onSuccess(response);
} catch (Exception e) {
e.printStackTrace();
webinterface.onFail(e);
}
}
return response;
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
}
}

I have found the problem, it is because of runOnUiThread is missing.

Android, it failed to upload an image to server

I am trying to upload an image file using multipart method to the server.
Here are my codes.
package com.example.test_multipart;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn1 = (Button) findViewById(R.id.button1);
btn1.setOnClickListener(new OnClickListener() {
TestAsyncTask asyncTask = new TestAsyncTask();
#Override
public void onClick(android.view.View v) {
// TODO Auto-generated method stub
new TestAsyncTask().execute();
}
});
}
public class TestAsyncTask extends AsyncTask<HttpResponse, Integer, Long> {
private ProgressDialog mDialog = new ProgressDialog(MainActivity.this);
long totalSize;
String url = "http://bridgecall.co.kr:5000/apis/settings/profile_update";
#Override
protected Long doInBackground(HttpResponse... arg0) {
// Register parameters
Map<String, Object> params = new HashMap<String, Object>();
params.put("phone", "01030195208");
params.put("name", "YUJIHYN");
Map<String, File> fileParams = new HashMap<String, File>();
File f = new File("/DCIM/Camera/test.jpg");
fileParams.put("file", f);
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Connection", "Keep-Alive");
httpPost.setHeader("Accept-Charset", "UTF-8");
httpPost.setHeader("ENCTYPE", "multipart/form-data");
CustomMultipartEntity multipart = new CustomMultipartEntity(
new ProgressListener() {
#Override
public void transferred(long transferred) {
// TODO Auto-generated method stub
publishProgress((int) transferred);
}
});
// Params
for (String strKey : params.keySet()) {
StringBody body = new StringBody(params.get(strKey)
.toString());
multipart.addPart(strKey, body);
}
// attach a file
for (String keys : fileParams.keySet()) {
multipart.addPart(keys, new FileBody(fileParams.get(keys)));
}
totalSize = multipart.getContentLength();
mDialog.setMax((int) totalSize);
httpPost.setEntity(multipart);
HttpResponse response = httpClient.execute(httpPost);
Log.v("checkcheckcheckcheck ", "checkcheckcheckcheck");
HttpEntity entity=response.getEntity();
InputStream is = entity.getContent();
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).append("\n");
}
is.close();
} catch (Exception e) {
return 0L;
}
return 0L;
}
#Override
protected void onCancelled() {
super.onCancelled();
mDialog.dismiss();
}
#Override
protected void onPostExecute(Long result) { // ui.
super.onPostExecute(result);
mDialog.dismiss();
}
#Override
protected void onPreExecute() {
super.onPreExecute();
mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mDialog.setCancelable(true);
mDialog.setOnCancelListener(cancelListener);
mDialog.setMessage("Uploading...");
mDialog.show();
}
#Override
protected void onProgressUpdate(Integer... progress) {
super.onProgressUpdate(progress);
// Progress update
mDialog.setProgress((int) progress[0]);
}
OnCancelListener cancelListener = new OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
}
};
}
}
It doesn't work after this line.
Log.v("checkcheckcheckcheck ", "checkcheckcheckcheck");
I get 400 error from the server.
It works fine if I upload an image on HTML. Can you see what is the problem?

Passing Value of Asynctask in Fragment

I have been working with passing the result created by the onPostExecute of AsyncTask in Fragment.
I know how to do it in Activity, like ((MyActivity)context).someMethod();
But how can I do this in Fragment?
I do ((MyFragment)contextOfAsyncTask).methodInFragment() but it gives me an error "Cannot cast from Context to MyFragment".
Here is my code in AsyncTask
class AsyncMethod extends AsyncTask{
ArrayList<MyObject> myVar= new ArrayList<MyObject>();
String result;
ListView lv;
Context contextOfAsyncTask;
public AsyncMethod(Context xc, ListView xl){
contextOfAsyncTask= xc;
lv = xl;
}
#Override
protected void onPreExecute() {
}
#Override
protected Void doInBackground(Void...param) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(http://www.myurl.com/something.php);
HttpResponse httpResponse = httpclient.execute(httppost);
HttpEntity httpEntity = httpResponse.getEntity();
result = EntityUtils.toString(httpEntity);
return null; //EVERYTHING IS WORKING FINE HERE, AND I CAN GET THE VALUE
}
#Override
protected void onPostExecute(Void res) {
//it does not work here
((MyFragment)contextOfAsyncTask).methodInFragment(result);
}

It is look like you want to call method from AsyncTask
class YourTask extends AsyncTask<Void, Void, Void> {
private SomeFragment fragment;
YourTask(SomeFragment fragment) {
this.fragment = fragment;
}
#Override
protected Void doInBackground(Void... params)
{
//do whatever you want to do
}
#Override
protected void onPostExecute(Void res)
{
fragment.yourmethod();
}
}
i hope it help..

CallBack gives a NullPointException

I'm trying to make a simple webreader work in an AsyncTast,
main thread
public class main extends Activity implements CallBackListener{
...
WebReader wr = new WebReader();
wr.execute("http://www.google.com");
...
#Override
public void callback(String res)
{
Log.e("eee",res);
}
...
}
...
interface CallBackListener
{
void callback(String res);
}
and webreader
class WebReader extends AsyncTask<String, Void, String>{
CallBackListener mListener;
public void setListener(CallBackListener listener){
mListener = listener;
}
#Override
protected String doInBackground(String... urls) {
String response = "";
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(urls[0]);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
#Override
protected void onPostExecute(String result) {
Log.e("s3","ss"+result);
mListener.callback(result); // null point here
}
}
yet it crashed with a nullpoint at mListener.callback ... any ideas what might be wrong?
Thanks!

You are not setting a listener. You should have something like this:
WebReader wr = new WebReader();
wr.setListener( new YourCallbackListener() );
wr.execute("http://www.google.com");
