URL is not redirecting to home page after sending token android?

I have a login activity that works fine,after successfully login i get token which i send it to the webview fragment by SharedPreferences and pass it to WebviewClient but it doesn't redirect to the homepage URL of the site which is inside webview,it's redirect to login page URL of the site inside Webview.I didn't find helpful solution.
Thanks in advance
My code:
Login Activity
btnSignin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
fetchToken();
}
});
}
private void fetchToken() {
String email = txtUsername.getText().toString();
String password = txtPassword.getText().toString();
UserRequest userRequest = new UserRequest(email, password);
RxUtil.asyncConsumer(service.getToken(userRequest), new Consumer<TokenResponse>() {
#Override
public void accept(TokenResponse response) throws Exception {
Log.d("ResponseToken", "" + response.getSuccess().getToken());
if (response.getSuccess() != null) {
String token = response.getSuccess().getToken();
setKeyToken(token);
Intent intent = new Intent(LoginActivity.this,MainActivity.class);
startActivity(intent);
}else {
Toast.makeText(LoginActivity.this, "Something went wrong please try again", Toast.LENGTH_LONG).show();
}
}
});
}
private void setKeyToken(String token) {
preferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString(KEY_TOKEN, token);
editor.apply();
}
public String getKeyToken() {
preferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE);
return preferences.getString(KEY_TOKEN, "");
}

Unable to get Saved shared preferences in the fragment

I am working on a app and while getting my shared preferences(which are saved in login activity), i am trying to get it in dashboard fragment but i am not be able to get it. After this i checked whether the is saved or not so then i used
boolean ok= editor.commit();
Toast.makeText(Login.this, "Saved: "+ok, Toast.LENGTH_LONG).show();
My toast shows message as Saved:true
After this try i am assuming that my data is saved to preferecnces but i am unable to fetch it. Below is my dashboard fragmenr code.
public class dashboard extends Fragment {
private TextView comp_text,mail_text,gst_text;
private String mUsername;
private SharedPreferences mSharedPreferences;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//this inflates out tab layout file.
View x = inflater.inflate(R.layout.dashboard_frag, null);
comp_text=(TextView)x.findViewById(R.id.company_id);
mail_text=(TextView)x.findViewById(R.id.email_id);
gst_text= (TextView)x.findViewById(R.id.gst_id);
initSharedPreferences();
Toast.makeText(getActivity(), "Logged member-> "+mUsername, Toast.LENGTH_LONG).show();
return x;
}
private void initSharedPreferences() {
mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
mUsername = mSharedPreferences.getString(Constants.USERNAME, "");
}
}
Here my Toast show **logged member-> **, that means musername have nothing to print and preferences are unable get.
I'm still confused this is my point of view if you want i can show where i saved preferences.
Help will be appreciated !
THANKS !
EDIT 1 ----
Here is my onResponse function where i saved preferences.
public void onResponse(Call<ServerResponse> call, retrofit2.Response<ServerResponse> response) {
if(response.isSuccessful()) {
ServerResponse serverResponse = response.body();
if(serverResponse.getMessage().equals(username)) {
SharedPreferences.Editor editor = mSharedPreferences.edit();
editor.putBoolean("LoggedIn",true);
editor.putString(Constants.USERNAME,serverResponse.getMessage());
boolean ok= editor.commit();
Toast.makeText(Login.this, "Saved: "+ok, Toast.LENGTH_LONG).show();
goToProfile();
}
} else {
Gson gson = new Gson();
ServerResponse errorResponse = null;
try {
errorResponse = gson.fromJson(response.errorBody().string(), ServerResponse.class);
} catch (IOException e) {
e.printStackTrace();
}
Snackbar.make(loginButton,errorResponse.getMessage(),Snackbar.LENGTH_SHORT).show();
}
}

Try this
SharedPreferences.Editor editor = getSharedPreferences("my_prefs", MODE_PRIVATE).edit();;
editor.putBoolean("LoggedIn",true);
editor.putString(Constants.USERNAME,serverResponse.getMessage());
boolean ok= editor.commit();
And then in Fragment
mSharedPreferences = getActivity().getSharedPreferences("my_prefs", MODE_PRIVATE); ;
mUsername = mSharedPreferences.getString(Constants.USERNAME, "");

How to auto login with Firebase in Android Studio?

I am creating a restaurant app for members & non-members. The home page consist of 3 buttons- menu, sign-in and sign-up. I want to let non-members auto login (default phoneId)into the system when they tap on the menu button and members will just sign-in or sign-up each time.
I tried to use sharedPreferences (default phoneId) for the non-member auto login but I don't know whether the default phoneId can be sync with firebase. I want to track the transaction orders for the non-members. Is there any way to only let the default phoneId to have auto login function?
p/s I am just a beginner and doing this app for my project. pls help thanks.

} catch (Exception e) {
Log.e(TAG, String.valueOf(e));
}
}
// Get userPassword
public String getUserPassword(){
return sharedPreferences.getString(USER_PASSWORD,"default_password");
}
}

the whole approach is rather questionable, because there is an anonymous authentication provider, which should be used for those "non-members" (and it can also be used together with security rules). storing the state of the authentication to Preferences is prone to errors, because it does not consider the actual state of the authentication - which will result in access denied, once the token expired.
I've also seen your previous question, while nevertheless the whole business logic is flawed.
... better see AccountManager, for how to properly store accounts on Android.

You need to do something like this,
MainActivity -> SignIn -> if SignIn success -> Next time you launch the app land to Home Activity
Try this,
1.) First, you define a new boolean preferences key, USER_LOGGED_IN and create setUserLoggedIn() and getUserLoggedIn() methods in your AppPreferences class as below.
private static final boolean USER_LOGGED_IN = false;
public static void setUserLoggedIn(boolean value) {
String TAG = "AppPref:setUserLoggedIn";
try{
editor.putBoolean(USER_LOGGED_IN, value);
editor.commit();
} catch (Exception e) {
Log.e(TAG, String.valueOf(e));
}
}
public static boolean getUserLoggedIn() {
return sharedPreferences.getBoolean(USER_LOGGED_IN, false);
}
2.) Then, in your SignIn Activity, If login success, set UserLoggedIn as true in your sharedPreferences.
3.) Finally, In your MainActivity, override onResume() method as follows,
#Override
protected void onResume() {
super.onResume();
boolean userLoggedIn = AppPreferences.getUserLoggedIn();
if(userLoggedIn){
MainActivity.this.startActivity(new Intent(getApplicationContext(), Home.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK));
}
}
Try this and let me know your feedback.
Thanks!

Android Studio - Using Volley to get JSON data from the server

This is my first attempt to create a login system in Android Studio and already got myself into trouble with my code.
My PHP script always returns something as JSON and I'm trying to parse that JSON in my LoginActivity, inside the login -method, but I'm getting
the following error after creditentials were forwarded to the server and the login button was clicked:
I/qtaguid﹕ Failed write_ctrl(u 43) res=-1 errno=22
I/qtaguid﹕ Untagging socket 43 failed errno=-22
W/NetworkManagementSocketTagger﹕ untagSocket(43) failed with errno -22
It did work earlier, when I was doing a stringRequest instead of jsonRequest, so everything should be fine on the server side. Since I'm very new to Android development, I'm unable to figure this one out by myself and need desperately your help.
Here's my LoginActivity without the imports:
public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
// Define Views
private EditText editTextEmail, editTextPassword;
private Button buttonLogin;
private ProgressBar progress;
private UserLocalStore userLocalStore;
private boolean loggedIn = false;
private final String TAG = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide(); // Hides the Action Bar for Login Activity
setContentView(R.layout.activity_login); // Sets the Content View
// Initializing Views
// EditText fields
editTextEmail = (EditText) findViewById(R.id.editTextEmail);
editTextPassword = (EditText) findViewById(R.id.editTextPassword);
// Buttons
buttonLogin = (Button) findViewById(R.id.buttonLogin);
// Other
progress = (ProgressBar) findViewById(R.id.progressBar);
// This method will set watcher for the EditTextFields
// The method will watch the value set to the EditTextFields.
// If there is nothing inputted in the EditTextField, "Login" button is disabled.
// Correspondingly, if there are text in the field, "Login" button is enabled.
watcher(editTextEmail, editTextPassword, buttonLogin);
// On-Click listeners
buttonLogin.setOnClickListener(this);
}
// Watcher method to check the value of EditText field
public void watcher(final EditText editText, final EditText editPassword, final Button button)
{
editText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
if (editText.length() == 0 && editPassword.length() == 0) // If length of the text field is equal to 0
button.setEnabled(false); // Disable the "Send" button
else
button.setEnabled(true); // Otherwise enable
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
});
if(editText.length() == 0 && editPassword.length() == 0)
button.setEnabled(false); //disable at app start
}
#Override
protected void onResume() {
super.onResume();
SharedPreferences sharedPreferences = getSharedPreferences(Config.SHARED_PREF_NAME, Context.MODE_PRIVATE);
loggedIn = sharedPreferences.getBoolean(Config.LOGGEDIN_SHARED_PREF, false);
// If the value of loggedIn variable is true
if(!loggedIn) {
// We will start the Courses activity
Intent intent = new Intent(LoginActivity.this, CourseActivity.class);
startActivity(intent);
}
}
private void login() {
// Get the values from the edit texts
final String email = editTextEmail.getText().toString().trim();
final String password = editTextPassword.getText().toString().trim();
// Creating a JSON Object request
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, Config.LOGIN_URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
// This line will not print out
System.out.println(response);
try {
String json_status = response.getString("status");
String message = response.getString("message");
if(json_status.equalsIgnoreCase(Config.LOGIN_SUCCESS)) {
System.out.println(message);
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// You can handle the error here if you want
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
// Adding parameters to request
params.put(Config.KEY_EMAIL, email);
params.put(Config.KEY_PASSWORD, password);
// Return parameters
return params;
}
};
// Adding the string request to the queue
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonObjectRequest);
}
#Override
public void onClick(View v) {
switch(v.getId()) {
// If button Login was clicked
case R.id.buttonLogin:
login(); // Start login method after "Login" button is clicked
// startActivity(new Intent(this, MainActivity.class));
break;
}
}
}
And here's my PHP:
<?php
require_once("dbconnect.php");
// POST Variables
$post_email = $_POST['email'];
$post_password = $_POST['password'];
// Prepare the SQL query
$stmt = $pdo->prepare("SELECT * FROM users WHERE email = :email");
$stmt->execute(array(
':email' => $post_email,
));
$row = $stmt->fetch(PDO::FETCH_ASSOC);
if($stmt->rowCount() > 0 && password_verify($post_password, $row['password']) && $row['role'] != 'staff') {
$user = array(); // Create an array for the user information
$user['id'] = $row['id'];
$user['name'] = $row['name'];
$user['email'] = $row['email'];
$user['password'] = $row['password'];
$user['role'] = $row['role'];
// echo json_encode(["message" => "success"]);
echo json_encode(["status" => "success", "message" => "Successfully logged in"]); // Format the array to JSON
} else {
echo json_encode(["status" => "error", "message" => "Incorrect creditentials"]);
}

You might not be passing the params, I usually use this syntax:
// Get the values from the edit texts
final String email = editTextEmail.getText().toString().trim();
final String password = editTextPassword.getText().toString().trim();
Map<String, Object> params = new ArrayMap<>(2);
// Adding parameters to request
params.put(Config.KEY_EMAIL, email);
params.put(Config.KEY_PASSWORD, password);
// Creating a JSON Object request
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(params),
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Log.d(TAG, response.toString());
// other stuff ...
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
// You can handle the error here if you want
}
});
// Adding the string request to the queue
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonObjectRequest);
Also, you might want to handle all the volley requests in a Singleton class, have a look at this SO question.
Hope this helps in any way :)

After "cancel" click on Twitter, request token for the page is invalid (Twitter4j)

I am using Twitter4j to let my user's sign in to their Twitter account. They are able to successfully log in and out, but a problem occurs if they hit "cancel" on the Twitter popup dialog and go back to the app and then reopen the login, the login gives an error saying the request token for the page is invalid. I know I have the right consumer/secret keys because the login works if I don't click cancel and log in normally. Any ideas?

Try adding an onCancelListener for the dialog and within that set the OAuthAccessToken to null.
mAuth_dialog.setOnCancelListener(new OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
sTwitter.setOAuthAccessToken(null);
}
});
