"User Already Exists !" how to get inner body value like "User Already Exists !" I am using DOM Parser
please post any example

private EditText email, name, mobile, password;
TextView tv;
private Button submit;
// private String Email, Name, Mobile, Password;
#Override

SharedPreferences variable is only received and can be shown on a second execution

I searched all forums and solutions but none did the trick. I have an app that scans some text and receive the scan text and show it. This is the file where I get the scan results:
#Override
public void extractData(RomaniaIdFrontRecognizer.Result result) {
super.extractData(result);
savePreferences("selected", result.getLastName());
add(R.string.PPLastName, result.getLastName());
add(R.string.PPFirstName, result.getFirstName());
add(R.string.PPIdentityCardNumber, result.getCardNumber());
add(R.string.PPSeries, result.getIdSeries());
add(R.string.PPCNP, result.getCnp());
add(R.string.PPNationality, result.getNonMRZNationality());
add(R.string.PPPlaceOfBirth, result.getPlaceOfBirth());
add(R.string.PPAddress, result.getAddress());
add(R.string.PPIssuingAuthority, result.getIssuedBy());
add(R.string.PPSex, result.getNonMRZSex());
add(R.string.PPValidFrom, result.getValidFrom());
add(R.string.PPValidUntil, result.getValidUntil());
}
private void savePreferences(String key, String value){
SharedPreferences sharedPreferences = mContext.getSharedPreferences("weightSetting", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString(key, value);
editor.commit();
}
This part is being executed because if I put a toast, the message shows.
And this is the file where I would want to receive the variable sent with sharedpreferences:

The send-receive variable with shared preferences worked but now, i don't know the cause, first time I get a null variable and if I try it again then I receive what I scan first. So, the variable is shown only the second time with the value scan for the first time. Even if I try to put a simple text and send it, it will show only the second time I make the action. But I repeat, the file is getting executed because if I put a toast, it will show. I think that the receiving of the shared preferences variable is done first and then the code from the first file is being executed. I tried to put the code in oncreate, onresume but nothing did the trick. Any help would be much appreciated.

The solution for me was to put a delay of 1 second for the process of receiving thorugh shared preferences. See below:
#Override
protected void onResume() {
super.onResume();
// clear saved state to be sure that data is cleared from cache and from file when
// intent optimisation is used
Timer timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
// Your logic here...
// When you need to modify a UI element, do so on the UI thread.
// 'getActivity()' is required as this is being ran from a Fragment.
ResultActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
// This code will always run on the UI thread, therefore is safe to modify UI elements.

String b= loadPreferences("prenume");

String h= loadPreferences("adresa");
String i= loadPreferences("emis");
String j= loadPreferences("sex");
String k= loadPreferences("start");
String l= loadPreferences("sfarsit");
usern= "";
String s = Normalizer.normalize(f, Normalizer.Form.NFD);
String bla = s.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");
String t = Normalizer.normalize(h, Normalizer.Form.NFD);
String bla1 = t.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");
String a1 = Normalizer.normalize(a, Normalizer.Form.NFD);
String bla2 = a1.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");
String b1 = Normalizer.normalize(b, Normalizer.Form.NFD);
String bla3 = b1.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");

// String s = loadPreferences("selected");

This is my code My problem was Intent Statement Not working in GoUserActivity funtion
At the same time Intent Statement Working well in OnCreate function.
When I try to run inside GoUserActivity,it will raise the runtime error(NullPoniterException "Intent i = new Intent(MainActivity.this,com.example.prakash.cinihive.UserActivity.class);")

I think you'll find things work better if you move your AsyncTask inside MainActivity as an inner class. You'll be able to call GoUserActivity() without having to new another instance of MainActivity, which you should never do.

Sentence is not inserted into online database not from all devices

When I insert a sentence from my android phone, the data is not inserted to my database. But when I use my friend's mobile, it works successfully.
It actually does not work when I use space between two words. But, when I use a single word, it works.
I use VARCHAR in my database.

use like that
class LoginTask extends AsyncTask<String, Void, Integer> {
private ProgressDialog progressDialog;
#Override
protected void onPreExecute()
{
progressDialog.show();
}
#Override
protected Integer doInBackground(String... arg0)
{
// do all login request here only
}
#Override
protected String onPostExecute(String arg0)
{
progressDialog.dismiss();
// get the response here and show where you want
}

Put in your OnClick method
new LoginTask().execute(stringParam);
to execute your method after clicking element.

In short:
You need to put your tryLogin() code into the doInBackground() method of the AsyncTask.
Incidentally, you should really take a look at your variable naming, the scope of your methods etc. Does tryLogin() really need to be protected? mUsername and mPassword are not member variables of the class, they are local variables.

How to use ProgressBar to show a spinner while waiting a httpResponse from server

I'm trying to show a loading icon to the user when the application makes a query to online Database. I've tried using a AnimationDrawable (I gave up because there was no need of a custom icon), ProgressDialog and ProgressBar.
The ProgressBar seems most appropriate, since I don't want a message, just a spinning icon. But I can not even make a ProgressBar appear on the screen, doesn't matter where I call it.
I've got the ProgressDialog appearing in screen, but it only appears after the server's response, and if I use dismiss() or cancel() it doesn't even appear at all.
I've had any success using AsyncTasks or Threads.
In the app, there is a class JogarActivity.java that attemps to show a list of options. It receives some parameters like the user id, and calls UserFunctions:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.jogar_layout);
Intent in = getIntent();
String url = this.getString(R.string.urlSite);
ArrayList<HashMap<String, String>> respostaList = new ArrayList<HashMap<String, String>>();
String idt = in.getStringExtra(TAG_ID);
primeiraPergunta = in.getBooleanExtra(TAG_PRIMEIRAPERGUNTA, true);
TextView insertPergunta = (TextView) findViewById(R.id.insertPergunta);
ListView insertRespostas = (ListView) findViewById(R.id.listResposta);
SharedPreferences settings = getSharedPreferences("PREFS_LOGIN", MODE_PRIVATE);
Integer idUsuario = settings.getInt("idUsuario", 0);
String idUser = idUsuario.toString();
if (primeiraPergunta){
UserFunctions userFunction = new UserFunctions();
json = userFunction.getJogar(idt, idUser);
}else{
try {
json = new JSONArray(in.getStringExtra(TAG_JSON));
json = json.getJSONArray(2);
} catch (JSONException e) {
e.printStackTrace();
}
}
Below is the getJogar function in userFunctions:
public JSONArray getJogar(String categoria, String usuarioId){
List params = new ArrayList();
params.add(new BasicNameValuePair("categoria", categoria));
params.add(new BasicNameValuePair("idUsuario", usuarioId));
JSONArray json = jsonParser.getJSONFromUrl(perguntaURL, params);
return json;
}
JSONParser.java is the class that makes the httpRequest:
public JSONArray getJSONFromUrl(String url, List params) {
// Making HTTP request
try {
// defaultHttpClient
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
// json = EntityUtils.toString(httpEntity);
// HttpEntity httpEntity2 = httpEntity;
json = EntityUtils.toString(httpEntity);
// is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
//then makes the JSON manipulation
As long as JSONParser and userFunctions aren't activities, I couldn't use ProgressDialogs inside them (Can't get the application context). All server requests are made in JSONParser.java, that's why i've first tried to put the ProgressDialog/ProgressBar there.
The closest that i've reached was using this code in JogarActivity (It shows the ProgressDialog, but after getting server's response. And if I use dismiss, it doesn't even appears)
final ProgressDialog loader = new ProgressDialog(JogarActivity.this);
loader.show();
//...the if-else code i've pasted above
loader.dismiss();
Even using runOnUiThread it doesn't works! I'm getting without options...
Thanks for all help.
