Can't log out on button click on my android app

i made an app using java language, Retrofit2 and REST API for server side. in me API class i have login and register parameters like
public interface ApiInterface {
#FormUrlEncoded
#POST("/login")
void login(#Field("email") String email, #Field("password") String password, Callback<LoginResult> cb);
public static class LoginResult
{
public int status;
public String user_api_hash;
}
#GET("/registration_status")
void registrationStatus(#Query("lang") String lang, Callback<RegistrationStatusResult> cb);
public static class RegistrationStatusResult
{
public int status;
}
#GET("/get_user_data")
void getMyAccountData(#Query("user_api_hash") String user_api_hash, #Query("lang") String lang, Callback<GetMyAccountDataResult> cb);
public static class GetMyAccountDataResult
{
public String email, expiration_date, plan;
public int days_left, devices_limit;
}
my login class is working properly i can login and register any time. when logged in i receive api_kay then it's saved and use in all the app for requests DataSaver.getInstance(LoginActivity.this).save("api_key", loginResult.user_api_hash); my loginActivity looks like :
public class LoginActivity extends AppCompatActivity {
private static final String TAG = "EditObjectActivity";
#Bind(R.id.username)
EditText username;
#Bind(R.id.password)
EditText password;
#Bind(R.id.signin)

private String UrlPrefix;
private String customServerAddress="https://voila_voila_mon_url.com/";
ProgressDialog progressDialog;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
final NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if(activeNetwork == null) {
Intent intent = new Intent(LoginActivity.this, NoInternetActivity.class);
startActivity(intent);
}

progressDialog = new ProgressDialog(this);
signin = (Button) findViewById(R.id.signin);
pwreset = (Button) findViewById(R.id.register);
password = findViewById(R.id.password);
username = findViewById(R.id.username);
String ip = getResources().getString(R.string.ip);
String httpsOn = getResources().getString(R.string.https_on);
String server_base = customServerAddress;
DataSaver.getInstance(LoginActivity.this).save("server_base", server_base);
DataSaver.getInstance(LoginActivity.this).save("server", server_base + "api/");
if (ip.isEmpty()) {
enableRegistration();
}
else {
API.getApiInterface(LoginActivity.this).registrationStatus("en", new Callback<ApiInterface.RegistrationStatusResult>()
{
#Override
public void success(ApiInterface.RegistrationStatusResult result, Response response)
{
if (result.status == 1) {
enableRegistration();
}
}
#Override
public void failure(RetrofitError retrofitError) {
Log.e(TAG, "failure: retrofitError" + retrofitError.getMessage());
Toast.makeText(LoginActivity.this, getString(R.string.errorHappened), Toast.LENGTH_SHORT).show();
}
});
}
signin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(customServerAddress != null) {
String server_base = customServerAddress;
server_base = UrlPrefix + server_base;
DataSaver.getInstance(LoginActivity.this).save("server_base", server_base);
DataSaver.getInstance(LoginActivity.this).save("server", server_base + "api/");
}
API.getApiInterface(LoginActivity.this).login(username.getText().toString(), password.getText().toString(), new Callback<ApiInterface.LoginResult>()
{
#Override
public void success(ApiInterface.LoginResult loginResult, Response response)
{ // progress dialogue
progressDialog = new ProgressDialog(LoginActivity.this);
progressDialog.setMessage("En cours..."); // Setting Message
progressDialog.setTitle("Connexion au serveur"); // Setting Title
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); // Progress Dialog Style Spinner
progressDialog.show(); // Display Progress Dialog
progressDialog.setCancelable(false);
new Thread(new Runnable() {
public void run() {
try {
Thread.sleep(10000);
} catch (Exception e) {
e.printStackTrace();
}
progressDialog.dismiss();
}
}).start();
//end progress dialogue
DataSaver.getInstance(LoginActivity.this).save("api_key", loginResult.user_api_hash);
Log.d("LoginActivity", "api_key: " + loginResult.user_api_hash);
if(customServerAddress == null)
{
String url = "https://voila_voila_mon_url.com/";
DataSaver.getInstance(LoginActivity.this).save("server_base", url);
DataSaver.getInstance(LoginActivity.this).save("server", url + "api/");
}
Intent intent = new Intent(LoginActivity.this, MapActivity.class);
startActivity(intent);
finish();
}
#Override
public void failure(RetrofitError retrofitError)
{
Toast.makeText(LoginActivity.this, getString(R.string.wrongLogin), Toast.LENGTH_SHORT).show();
}
});
}
});
}
}
now the thing is i'd look to log out in my mean activity. in my reseachs i have been told that once logged out the api_key in DataSaver.getInstance(LoginActivity.this).save("api_key", loginResult.user_api_hash); should be null like api_key =null.also when i open the app it show that i am logged. i want to log out.here is my example on my_logout button i did this :
disconnect.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String log_out = null;
if(DataSaver.getInstance(this).load("api_key") != null){
DataSaver.getInstance(this).load("api_key") == log_out;
finish();
}else{
//Toast.......(Toast with message ->>>>unable to log out).
}
});
This DataSaver.getInstance(this).load("api_key") is used in all the app when requesting for GET method when fetching users datas. the api_key saved in the app allow me to make some requests as said before. but when this is null it's impossible to make requests. i want to destroy the session when logged in by loggin out. if you understand what i say and can help please.
my account activity after logged in
public class MyAccountActivity extends AppCompatActivity
{
#Bind(R.id.back) View back;
#Bind(R.id.expandable_list) ExpandableListView expandable_list;
#Bind(R.id.loading_layout) View loading_layout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_account);
ButterKnife.bind(this);
loading_layout.setVisibility(View.VISIBLE);
API.getApiInterface(this).getMyAccountData((String) DataSaver.getInstance(this).load("api_key"), getResources().getString(R.string.lang), new Callback<ApiInterface.GetMyAccountDataResult>() {
#Override
public void success(ApiInterface.GetMyAccountDataResult dataResult, Response response)
{
MyAccountAdapter adapter = new MyAccountAdapter(MyAccountActivity.this, dataResult);
expandable_list.setAdapter(adapter);
Utils.setGroupClickListenerToNotify(expandable_list, adapter);
loading_layout.setVisibility(View.GONE);
expandable_list.setVisibility(View.VISIBLE);
}
#Override
public void failure(RetrofitError retrofitError) {
Toast.makeText(MyAccountActivity.this, R.string.errorHappened, Toast.LENGTH_SHORT).show();
}
});
}

i did this but it's not enough to log out #Syed Ibrahim
like this
but not working this is juste to stay connected not to log out
if (DataSaver.getInstance(this).load("api_key") == null)
{
startActivity(new Intent(MapActivity.this, LoginActivity.class));
finish();
return;
}
what i need is to set this api_key null whatever the app is running or not.

after alot of researches i found that set and get class and i modify my code as below
public class Post {
private String message;
private String number;
private String user;
private String date;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
}
then in activity that i need to Post data to firbase database i add that simple code
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference posts = database.getReference("Messages:");
//this code for keep posts even app offline until the app online again
posts.keepSynced(true);
Post post = new Post();
post.setMessage("Messsage");
post.setUser(name);
post.setNumber(num);
post.setDate(s);
posts.push().setValue(post);

Authentication failed.com.google.firebase.FirebaseException: An internal error has occured. [ OPERATION_NOT_ALLOWED ]

I keep getting this error while attempting to sign up on an emulator and on my device.
Authentication failed.com.google.firebase.FirebaseException: An internal error has occured. [ OPERATION_NOT_ALLOWED ]
I have enabled email under authentication providers in the console as was suggested in a different question but I'm still having trouble. Any ideas?
I have the play services dependencies set to higher than 9.0.0 and both the emulator and my test device satisfy this requirement

Please check the if authentication method enabled in the console Firebase or not.
If you did not enabled Google authentication, you will got the same exception, just without [OPERATION_NOT_ALLOWED].
For more information you can check solution in the forum post https://groups.google.com/forum/#!topic/firebase-talk/JTaIlD-tNxw
Please check the Firebase Auth documentation for more information.
I have same problem. I got the solution in above forum post.

clicking report activity nothing was happening in android

Hi in the below code when clicking the report button not going to login activity even though it's not happening anything.
In login activity first of all I am checking the login username and password using session object.
if the username and password working fine and then want to move to next activity.
Can any one help me from this issue.
Mainactivity.java
report1=(TextView)findViewById(R.id.report1);
report=(ImageView)findViewById(R.id.report);
report1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});
report.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});
In the below when I am putting comment for session then it's moving but after entering the username and password it was showing logcat Admin user found but not going to next activity.it was staying in same activity itself.

Do not use the application's context, use the context the view currently be presented.
report.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(v.getContext(), Login.class);
startActivity(i);
}
});
