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 a = loadPreferences("nume");
String b= loadPreferences("prenume");
String c= loadPreferences("nr");
String d= loadPreferences("serie");
e= loadPreferences("cnp");
String f= loadPreferences("nationalitate");
String g= loadPreferences("locn");
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 g1 = Normalizer.normalize(g, Normalizer.Form.NFD);
String bla4 = g1.replaceAll("[\\p{InCombiningDiacriticalMarks}]", "");
nume = (EditText) findViewById(R.id.nume);
nume.setText(bla2);
prenume = (EditText) findViewById(R.id.prenume);
prenume.setText(bla3);
nr = (EditText) findViewById(R.id.nrserie);
nr.setText(c);
serie = (EditText) findViewById(R.id.serie);
serie.setText(d);
cnp = (EditText) findViewById(R.id.cnp);
cnp.setText(e);
nationalitate = (EditText) findViewById(R.id.nationalitate);

// String s = loadPreferences("selected");
// Toast.makeText(getApplicationContext(), a,Toast.LENGTH_LONG).show();

Response:wrong. [User registration via android app using http post not working]

I don't understand why it keeps on saying Response is : Wrong. Tired of spending almost a day .. I am here seeking help.
Excuse me if my questions seems naive.
Thank you in advance.

try below code:-
HttpResponse httpResponse = httpClient.execute(httpPost);
if (httpResponse != null)
{
InputStream in = httpResponse.getEntity().getContent();
result = ConvertStreamToString.convertStreamToString(in);
// System.out.println("result =>" + result);
}
convertStreamToString method
public String convertStreamToString(InputStream is)
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try
{
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{
try
{
is.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
return sb.toString();
}
do not under stand :-
HttpResponse httpResponse = httpClient.execute(httpPost); // getting response from server
// where you use this response and why using below line or whats the benefit of below line
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpClient.execute(httpPost, responseHandler);

Hope this helps you!!!
If its not working please let me know i will try to help more...

Try using Volley if not. It's faster than the ussual HTTP connection classes.
Example:
RequestQueue queue = Volley.newRequestQueue(this);
String url = "url";
JSONObject juser = new JSONObject();
try {
juser.put("locationId", locID);
juser.put("email", email_input);
juser.put("password", password_input);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, url, juser, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// TODO Auto-generated method stub
txtDisplay.setText("Response => "+response.toString());
findViewById(R.id.progressBar1).setVisibility(View.GONE);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
}
});
queue.add(jsObjRequest);

Like #Andrew T suggested , I am posting my solution.
The mysql_error()helped me debug the issue. mysql_error() displayed in the Logcat that "register table is not found" .. but the table name is registers. I was missing "s" at the end.
$fullname = $_POST['fullname'];
$email = $_POST['email'];
$password = $_POST['password'];
$insert_data = "INSERT INTO registers(id, fullname, email, password)
Values ('','$fullname', '$email', '$password')";
$insert_result = mysql_query($insert_data) or die(mysql_error());
//echo "Signed Up";
if($insert_result){
echo "Signed Up";
}
else{
echo "wrong!";
}
Everything worked perfect after that. Again, thank you all for your time and solutions. Everyone's suggestions are great, but I can not accept any answer at this point.. sorry:(

login page with httpget and asynctask in android

Hi I'm new to android and have task to create a login page that will connect with server and check user exist using http Get and AsyncTask and PHP API for this is ready. i went through few tutorials on AsyncTask and i understood but i m not sure how to work with http Get and AsyncTask. can anyone please help how to link both and create login page.
P.S: i have two EditText to accept username and password and two Buttons one for login and other for register and have corresponding DB as well.

please someone help me.android version3.2, try to run using XOOM2 emulator

The reason is that your login method makes an http connection in the ui thread, you should do it in a separate thread or use an AsynchTask..
You can pass the context to the task, and then:
protected void onPostExecute(Void result) {
Intent showContent = new Intent(context, yourActivity.class);
context.startActivity(showContent);
}

I dont advise it though but you can use this for test. Refer to #imran khan for good practice.
Add this in your onCreate() method to bypass the checking.
if( Build.VERSION.SDK_INT >= 9){
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}

StartActivity() red highlighted

Basically I want to have a button to start a new activity after login.
I found that I was not able to call the StartActivity() as what I did before in the login page.Please guide
This is the login page where I used StartActivity(this,sth.class)sucessfully
public class Login extends Activity
{
/** Called when the activity is first created. */
Button login;
String name="",pass="";
EditText username,password;
TextView tv;
byte[] data;
HttpPost httppost;
StringBuffer buffer;
HttpResponse response;
HttpClient httpclient;
InputStream inputStream;
SharedPreferences app_preferences ;
List<NameValuePair> nameValuePairs;
CheckBox check;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
app_preferences = PreferenceManager.getDefaultSharedPreferences(this);
username = (EditText) findViewById(R.id.username);
password = (EditText) findViewById(R.id.password);
login = (Button) findViewById(R.id.login);
check = (CheckBox) findViewById(R.id.check);
String Str_user = app_preferences.getString("username","0" );
String Str_pass = app_preferences.getString("password", "0");
String Str_check = app_preferences.getString("checked", "no");
if(Str_check.equals("yes"))
{
username.setText(Str_user);
password.setText(Str_pass);
check.setChecked(true);
}
login.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
name = username.getText().toString();
pass = password.getText().toString();
String Str_check2 = app_preferences.getString("checked", "no");
if(Str_check2.equals("yes"))
{
SharedPreferences.Editor editor = app_preferences.edit();
editor.putString("username", name);
editor.putString("password", pass);
editor.commit();
}
if(name.equals("") || pass.equals(""))
{
Toast.makeText(Login.this, "Blank Field..Please Enter", Toast.LENGTH_LONG).show();
}
else
{
try {
httpclient = new DefaultHttpClient();
httppost = new HttpPost("http://fyptest.comyr.com/main.php");
// Add your data
nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("UserEmail", name.trim()));
nameValuePairs.add(new BasicNameValuePair("Password", pass.trim()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
response = httpclient.execute(httppost);
inputStream = response.getEntity().getContent();
data = new byte[256];
buffer = new StringBuffer();
int len = 0;
while (-1 != (len = inputStream.read(data)) )
{
buffer.append(new String(data, 0, len));
}
inputStream.close();
}
catch (Exception e)
{
Toast.makeText(Login.this, "error"+e.toString(), Toast.LENGTH_LONG).show();
}
if(buffer.charAt(0)=='Y')
{
Toast.makeText(Login.this, "login successfull", Toast.LENGTH_LONG).show();
Move_to_next();
}
else
{
Toast.makeText(Login.this, "Invalid Username or password", Toast.LENGTH_LONG).show();
}
}
}
});
check.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
// Perform action on clicks, depending on whether it's now checked
SharedPreferences.Editor editor = app_preferences.edit();
if (((CheckBox) v).isChecked())
{
editor.putString("checked", "yes");
editor.commit();
}
else
{
editor.putString("checked", "no");
editor.commit();
}
}
});
}
public void Move_to_next()
{
//may perform checking based on ID
startActivity(new Intent(this, MainMenu.class));
}
But this, my startActivity is being underlined in red
public class MainMenu extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu);
Button new_folder = (Button)findViewById(R.id.new_folder);
new_folder.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
// show another class
startActivity(new Intent(this,Folder_Details.class));
}
});
}
}
It shows "The constructor Intent(new View.OnClickListener(){}, Class) is undefined" and "Remove arguments to match Intent()" options
I have included the <Activity></Activity> in Manifest. And the code showed above, imports are cut off

Yes this is because, you are trying to use "this" with refernce to your button instead of your activity. You have to replace it like this,
Instead of startActivity(new Intent(this, Folder_Details.class));
do this,
startActivity(new Intent(MainMenu.this, Folder_Details.class));

Modify it as
startActivity(new Intent(MainMenu.this,Folder_Details.class));
You are using a View.OnClickListener instead of a Context instance.

startActivity(new Intent(MainMenu.this,Folder_Details.class));
