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";

}

//end progress dialogue
DataSaver.getInstance(LoginActivity.this).save("api_key", loginResult.user_api_hash);
Log.d("LoginActivity", "api_key: " + loginResult.user_api_hash);

}

finish();
}
#Override

}
});
}
});
}
}
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.

when i am pressing back button(up button) it is showing "app stopped unfortunately" after using volley

You have to send String Values for these two Keys "token","firstname".
final String Token=getIntent().getExtras().getString("token");
final String firstName=getIntent().getExtras().getString("firstname");
If you cant find it send the code snippet of intent in another class.

Content shared using dynamic link not getting displayed as same as it was shared after opening it

I'm developing an android app. Some data is getting retrieved from the FirebaseDatabase and is getting shown in a RecyclerView in my app.
The RecyclerView has cards in it. In every card, the images and text is shown. On the card there is a 'share' button, by clicking on which a dynamic-link is generated and is getting shared with anybody. When I click on the shared dynamic-link, the app gets open and what happens is that the image which was on the same card the share button was clicked is getting displayed, but the text is always getting displayed of the last saved data. I hope you got my point.
Here's how I'm generating dynamic-link:
Button btnShare = (Button) holder.itemView.findViewById(R.id.btn_share);
btnShare.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Uri BASE_URL = Uri.parse("http://www.appwebsite.com/");
holder.APP_URI = BASE_URL.buildUpon().path(imageUIDh).build();
packageName = holder.itemView.getContext().getPackageName();
deepLinkTS = Uri.parse("https://u9p25.app.goo.gl/?link="+holder.APP_URI+"&apn="+packageName+"&amv="+16+"&ad="+0);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Please help this needy: " + deepLinkTS.toString() + "\n-shared through app.");
holder.itemView.getContext().startActivity(Intent.createChooser(intent, "Share via..."));
}
});
Here's how I'm handling dynamic-link in onCreate() method of MainActivity.class:
boolean autoLaunchDeepLink = false;
AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, MainActivity.this, autoLaunchDeepLink)
.setResultCallback(
new ResultCallback<AppInviteInvitationResult>() {
#Override
public void onResult(#NonNull AppInviteInvitationResult result) {
if (result.getStatus().isSuccess()) {
// Extract deep link from Intent
Intent intent = result.getInvitationIntent();
final String deepLink = AppInviteReferral.getDeepLink(intent);
// Handle the deep link. For example, open the linked
// content, or apply promotional credit to the user's
// account.
final ProgressDialog openingSharedRequest = new ProgressDialog(MainActivity.this);
openingSharedRequest.setMessage("Opening shared help-request...");
openingSharedRequest.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Intent helpRequestIntent = new Intent(MainActivity.this, HelpRequestThroughDeepLink.class);
helpRequestIntent.putExtra("deepLink", deepLink);
// helpRequestIntent.putExtra("deepLinkTS", HelpRequest.deepLinkTS.toString());
// helpRequestIntent.putExtra("APP_URI", HelpRequest.ViewHolder.APP_URI.toString());
helpRequestIntent.putExtra("postedFrom", postedFromS);
// new AlertDialog.Builder(MainActivity.this)
// .setMessage(deepLink)
// .setPositiveButton("OK", null)
// .create()
// .show();
startActivity(helpRequestIntent);
openingSharedRequest.dismiss();
}
}, 1200);
// [START_EXCLUDE]
// Display deep link in the UI
// ((TextView) findViewById(R.id.link_view_receive)).setText(deepLink);
// [END_EXCLUDE]
} else {
// Log.d(TAG, "getInvitation: no deep link found.");
// Toast.makeText(getBaseContext(), "Some error occurred", Toast.LENGTH_SHORT).show();
}
}
});
// [END get_deep_link]

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.

When I run it, I type in my email / password and the application fails.

Have look at this code:
public class LoginActivity extends PlanndActivity
{
public EditText emailField;
public EditText passwordField;
public Button loginButton;
public View.OnClickListener loginButtonListener;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
PushService.setDefaultPushCallback(getApplicationContext(), PlanndActivity.class);
ParseInstallation.getCurrentInstallation().saveInBackground(
new SaveCallback() {
#Override
public void done(ParseException e) {
if(e!= null)
Log.e(Constants.TAG, "ERROR adding callback", e);
}
}
);
emailField = (EditText) findViewById(R.id.email_login);
passwordField = (EditText) findViewById(R.id.password_login);
loginButton = (Button) findViewById(R.id.login_button);
loginButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loginButton.setEnabled(false);
String email = ((EditText) findViewById(R.id.email_login)).getText().toString().trim();
String password = ((EditText) findViewById(R.id.password_login)).getText().toString().trim();
ParseUser.logInInBackground(email, password, new LogInCallback() {
#Override
public void done(ParseUser parseUser, ParseException e) {
if(parseUser != null)
{
// User is valid and is now logged in
Log.i(Constants.TAG, "Successful login for user " + parseUser.getUsername());
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
PushService.subscribe(getApplicationContext(), "user_" + ParseUser.getCurrentUser().getObjectId(), PlanndActivity.class);
}
else
{
loginButton.setEnabled(true);
Log.i(Constants.TAG, "Unsuccessful login for user");
// sign up failed and the problems
// needs to go and do the sign up activity
}
}
});
}
});
((Button)findViewById(R.id.register_button)).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(getApplicationContext(), RegisterActivity.class));
}
});
((Button)findViewById(R.id.fake_login)).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
emailField.setText("rberidon#gmail.com");
passwordField.setText("test");
}
});
}
}

Try implement this with animation of view like use inline progress bar when user clicks sign in, switch the content and progress bar depending on your logic!

The problem is that your are executing signUpInBackground() inside AsyncTask.doInBackground(). doInBackground is already using a background thread. Just use newUser.signUp()
