I need help. I have actionbar in my app. And I want my logout inside of it. How can I do that? I have already these things. But I don't have that session.java. I have attempt to copy others' code but it showed some errors. Please help me. Thanks guys!
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
logout();
return true;
}
return super.onOptionsItemSelected(item);
}
private void logout() {
session.logout();
startActivity(new Intent(this, MainActivity.class));
finish();
}
you need to use shared preference to keep the session and i think session.logout();this method created in a class where they keep the session using shared preference. ok right now i will tell you how can you keep your login session and how to logout.
step one : when you are trying to login and you got the success response through JSON Api or from your sqlite database just use shared preference and set positive flag value there.
setp two : and then when you click logout button from toolbar in onOptionsItemSelected method just change that shared preference's value to negative.
Like this sir?
public class LoginActivity extends AppCompatActivity {
SharedPreferences sharedpreferences;
public static final String my_shared_preferences = "my_shared_preferences";
public static final String session_status = "session_status";
Boolean session = false;

//Check session login if TRUE then go directly MainActivity
sharedpreferences = getSharedPreferences(my_shared_preferences, Context.MODE_PRIVATE);
session = sharedpreferences.getBoolean(session_status, false);

I am facing an issue with retrofit login. when i run the application in my cell phone , i logged in with a registered user... login successful... but when i logged out and want to re-login with another account the "application logged me in with the previous account" ... i am not understanding what is this issue please help.
i am not understanding why this issue is occurring with my application.
Note: i am using retrofit (with Firebase) in the application for signup and login.

You're using SharedPreferences for storing login credentials. Once user enters valid login credentials (login ID and password) you store it in SharedPreferences in usersignin() method.
SharedPreferenceUtil.storeStringValue(Login_Activity.this, Constants.USERNAME, email);
SharedPreferenceUtil.storeStringValue(Login_Activity.this, Constants.PASSWORD, password);
Now, I am assuming (you only posted LoginActivity and didn't mention other parts) that your app has Splash page. Which appears before Login page. In which you decide whether the user has already logged in or not (using SharedPreference values). If yes, redirect to Home page else Login page.
The fix for this issue is very simple. When user logs out from the app, you need to clear SharedPreferences as well.
Like this,
SharedPreferenceUtil.storeStringValue(Login_Activity.this, Constants.USERNAME, null);
SharedPreferenceUtil.storeStringValue(Login_Activity.this, Constants.PASSWORD, null);
I want to log a user and save the username that logged in, and display it in the MainActivity as a Toast or TextView.
Here is the code I have currently:

editor.commit();

To repeat want to log user login information. Specifically I want to save the username that logged in and display it in the MainActivity as a Toast or TextView.
For what I read, I tried it with intent.putextra and with bundle, it will work at first install but after that it will crash the application, so I tried it with sharedpreference and created a session.
I am a bit blocked here. How do I save in the session each different user and then display its username in the MainActivity?
Sorry if i am doing something wrong its my first post.
You can make another paramater that can be put to SharedPref. For example in your set loggin :
public void setLoggedin(boolean loggedin, String username){
editor.putBoolean("loggedInmode",loggedin);
editor.putString("username",username);
editor.commit();
}
And in your main activity to get the username, you can make another method :
public boolean getUsername(){
return sharepref.getString("username", "");
}
you can call it with String username = session.getUsername();
I have already been fetched data from instagram api. But i cannot reach that data to use it on my service. I have tried all methods that i know.
**Here is my main object: ** If my followers count is increases or decreases, notify, And check that for every 5 min.(I am still working on it. There are lots of misses yet.)
**Here is my main question: ** Do i really have to create a new parser to fetch data that i already have or what should i build?
If you have any sample or Articles for this case, that would be useful.
I heard about Csv file. Is that can be useful to import ?

The only solution that i found is the adding parser to your service to reach data from api. None of the the method can access to reach data from service to activity.
I added this class to reach api data on service.
public void lilParser() throws IOException, JSONException{
URL url = new URL(API_URL + "/users/" + mSession.getId()
+ "/?access_token=" + mAccessToken);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoInput(true);
urlConnection.connect();
String response = Utils.streamToString(urlConnection
.getInputStream());
System.out.println(response);
JSONObject jsonObj = (JSONObject) new JSONTokener(response).nextValue();
JSONObject data_obj = jsonObj.getJSONObject("data");
JSONObject counts_obj = data_obj.getJSONObject("counts");
String name = jsonObj.getJSONObject("data").getString("full_name");
String bio =jsonObj.getJSONObject("data").getString("bio");
String counts=jsonObj.getJSONObject("data").getString("counts");
userInfoHashmap.put(TAG_FOLLOWED_BY,counts_obj.getString(TAG_FOLLOWED_BY));
Log.i(TAG,"followedby=>[" + counts + "]");
}
And, Here is my onCreate. You can check The data if it is changed or not.
#Override
public void onCreate() {
Toast.makeText(this,"Service Started", Toast.LENGTH_LONG).show();
myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
String fo = userInfoHashmap.get(TAG_FOLLOWED_BY);
try {
lilParser();
}
catch (IOException e) {e.printStackTrace();}
catch (JSONException e) {e.printStackTrace();}
if(new String(userInfoHashmap.get(TAG_FOLLOWED_BY)).equals(fo)==true){}
else {
getnotification();
}
}
}, 0, 30000);
}
PS: I published my code, that may help someone else. I am still newbie.
Here the group chat activity is running currently. Group chat activity means chat window. in that chat window i retrieved the message from sqlite and showed by list view adpater. Here i am doing group chat for one event when new message is arrived for other event the notification issued. When i click the notification my group chat activity is not executed again even if i passed the intent from other class or activity.
This is my groupchatActivity code
#Override

super.onStart();

editor.putInt("APPSTATUS", 1);
editor.putLong("eventId", activeEventMO.getEventId());
editor.commit();

You need to do couple of things to achieve the result.
Set launch mode of groupchatactivity to SingleTask
Override onNewIntent() method in groupchatactivity
Call setIntent(intent) for new received intent in onNewIntent()
Reflect as appropriate on above answer.
I am trying to develop a chat application with a login and registration. The app is working without any errors, when I register it adds the right information in SQLite but when i log in with those details the app says "Logging in" but nothing happens. Does anyone know what is wrong with my code?

it doesnt look like you ever log them in. look here
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String email = inputEmail.getText().toString();
String password = inputPassword.getText().toString();
// Check for empty data in the form
if (email.trim().length() > 0 && password.trim().length() > 0) {
// login user
checkLogin(email, password);
} else {
// Prompt user to enter credentials
Toast.makeText(getApplicationContext(),
"Please enter the credentials!", Toast.LENGTH_LONG)
.show();
}
}
});
what is checkLogin(email, password);
and if it is returning a boolean you should be saying
if(checkLogin){
//log them in
}
can you post the checklogin code?
