This is done on my loadscreen Activity and I want to set the listwriter to my SharedPreferences so that I can use it in another Activity. This is my session manager class. The logging in the AsyncTask shows me that the listwriter gets populated correctly. However, when I call on the getlistwriter in my other class I receive an empty ArrayList. I can't see where the error is.
public class SessionManager {
// LogCat tag
private static String TAG = SessionManager.class.getSimpleName();
private ArrayList<BetDisplayer> listwriter = new ArrayList<>();
// Shared Preferences
SharedPreferences pref;
Editor editor;
Context _context;
// Shared pref mode
int PRIVATE_MODE = 0;
// Shared preferences file name
private static final String PREF_NAME = "AndroidHiveLogin";
private static final String KEY_IS_LOGGEDIN = "isLoggedIn";
public static final String USERNAME = "username";
public SessionManager(Context context) {
this._context = context;
pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
public ArrayList<BetDisplayer> getListwriter() {
return listwriter;
}
public void setListwriter(ArrayList<BetDisplayer> listwriter) {
this.listwriter = listwriter;
}
public void setLogin(boolean isLoggedIn, String username) {
editor.putBoolean(KEY_IS_LOGGEDIN, isLoggedIn);
editor.putString(USERNAME, username);
// commit changes
editor.commit();
Log.d(TAG, "User login session modified!");
}
public HashMap<String, String> getUserDetails(){
HashMap<String, String> user = new HashMap<String, String>();

user.put(USERNAME, pref.getString(USERNAME, null));
// return user
return user;
}

In your SessionManager you're not saving your List into SharedPrefs. You should do something like this:
public static final String MY_LIST = "my_list";
private static final Type LIST_TYPE = new TypeToken<List<BetDisplayer>>() {}.getType();
to save:
public void setListwriter(ArrayList<BetDisplayer> listwriter) {
this.listwriter = new ArrayList<BetDisplayer>(listwriter);
mPrefs.edit()
.putString(MY_LIST, new Gson().toJson(listwriter));
.commit();
}
to load:
public ArrayList<BetDisplayer> getListwriter() {
if (listwriter == null) {
listwriter = new Gson().fromJson(mPrefs.getString(MY_LIST, null), LIST_TYPE);
if(listwriter == null){
listwriter = new ArrayList<BetDisplayer>();
}
}
return listwriter;
}
Your BetDisplayer must implements Serializable.
See here: Android array to Sharedpreferences with Gson
To use Gson just add this dependency: 'com.google.code.gson:gson:2.3.1' or download the .jar
UPDATE:
Create a Singleton that holds one reference only to your SharedPreferences editor, it's just a will guess but I think you are using different context to get your editor and that could be the problem (UPDATE 2: it's not, check here, but the Singleton approach it's a plus):
private static SharedPreferences mPrefs;
private static SessionManager sInstance = null;
protected SessionManager() {
mPrefs = AppController.getInstance().getApplicationContext().getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
}
public static SessionManager getInstance() {
if (sInstance == null) {
sInstance = new SessionManager();
}
return sInstance;
}
And when you need to use SharedPreferences use SessionManager().getInstance().someMethod();

alert box with no message, and dissmiss button (sorry i cant post a pic hehe)

I had the same problem AS THIS one of yours i have chosen to use volley library on android part where it helped me to pass input variable to php where clause
refer to this post and check the answer:
How to parse multiple rows with jsonOject
or follow the followithing tutorial watch function called function StoreUserInfo and refer to second part to activity called RegisterActivity.java these can help you to fetch using where clause:

ListAdapter error, seems like something wrong in "this". This my version how cut off code, where it stop return variables. Sorry for bad english, but i hope you understand me :)
Add my php json maker. Mb problem there?!
<?php
mysql_connect("localhost","root","");
if (!mysql_select_db("ololo")) {
echo "Unable to select ololo: " . mysql_error();
}
$sql=mysql_query("select streamer, yt_length from pm_videos where category='1'");
if(!$sql) exit("Error - ".mysql_error().", ".$tmp_q);
while($row=mysql_fetch_assoc($sql)){
$output[]=$row;
}
$json = json_encode($output);
header('Content-Type: application/json');
print "{\"data\": ${json}}";
mysql_close();
?>
You programm crashes because you are running
json = Parser.getJSONFromUrl(url);
in the UI Thread context. You have to use an AsyncTask
Code looks good. The only problem is that
public class ParsingTask extends AsyncTask<String, Void, ArrayList<HashMap<String, String>>>{
JSONParser Parser = new JSONParser();
protected Void doInBackground(String... urls) {
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String, String>>();
JSONObject json = Parser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
data = json.getJSONArray(TAG_DATA);
// looping through All Contacts
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
// Storing each json item in variable
String streamer = c.getString(TAG_STREAMER);
String viewers = c.getString(TAG_VIEWERS);
//String link = c.getString();
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_STREAMER, streamer);
map.put(TAG_VIEWERS, viewers);
//map.put(TAG_URL, link);
// adding HashList to ArrayList
dataList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
return dataList;
}
protected void onPostExecute(ArrayList<HashMap<String, String>> dataList) {
ListAdapter adapter = new SimpleAdapter(AndroidJSONParsingActivity.this, dataList,
R.layout.list_item,
new String[] { TAG_STREAMER, TAG_VIEWERS /*TAG_URL*/ }, new int[] {
R.id.streamer, R.id.viewers /*R.id.url*/ });
setListAdapter(adapter);
}
Have you heard about gson (docs)?
public static final class Content {
#SerializedName("streamer") // you don't need to specify this, JFYI
String streamer;
#SerializedName("yt_length") // you don't need to specify this, JFYI
String yt_length;
}
public static final class Data {
#SerializedName("data")
List<Content> data;
}
public static void main (String[] args) {
Gson gson = new GsonBuilder().create();
Data data = gson.fromJson(jsonString, Data.class);
}
And remember, you cannot call network operations on UI thread! this is reason of what you have for now.

I have to develop a login form android application.Here, i have to enter the username and password. If it is correct, fetch the email belonging to the username and display it in the textview and if the username and password is wrong, display login failed message.
This is my webservice code:
public class Login {
public String authentication(String username,String password) {
String retrievedUserName = "";
String retrievedPassword = "";
String retrievedEmail = "";
String status = "";
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root","");
PreparedStatement statement = con.prepareStatement("SELECT * FROM xcart_customers WHERE login = '"+username+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("login");
retrievedPassword = result.getString("password");
retrievedEmail = result.getString("email");
}
if(retrievedUserName.equals(username)&&retrievedPassword.equals(password)&&!(retrievedUserName.equals("") && retrievedPassword.equals(""))){
status = "Success";
}
else {
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}
return status;
}
};
This is my android code:
public class CustomerLogin extends Activity {

If the login is success, it will have to display the email on textview. How can i do that?
You can use asy task to do this,
in doInBackground
Do your login operations. Asyctask makes this operation in another task.
when complated in onPostExecute
show the success message. But you need to use runOnUiThread because you cant reach ui controls from non ui thread.
private class loginTask extends AsyncTask<URL, Integer, int> {
protected Long doInBackground(URL... urls) {
// start login process
return 1;
}
protected void onPostExecute(int result) {
_activity.runOnUiThread(new Runnable() {
#Override
public void run() {
textview.setText("login success");
}
});
}
}
