Get single JSON value from response Retrofit

Im trying to get a single value from JSON using Retrofit, i followed a tutorial but i got an error saying that "Class anonymous class derived from Callback must be either declared ...." .
what im specifically trying to achieve is to echo a single json property value in a empty string like String Axe = ""; and i fill it with a specific value from the json file from the server. here is what i tried.
Json format
"axe1": {"test1"}

So, i want the value of Json axe1 which is test1 to be parsed and put in into the empty string

You are using wrong import:
import com.android.volley.Response;
Replace it with
import retrofit2.Response;

Firstly, your JSON format is invalid, it should be {"axe1": "test1"}.
To store it you could do :
JSONObject json = new JSONObject(response.body().toString());
Log.i(LOG_TAG, json.getString("axe1"));

Passing String to another Activity not possible

I have tried a lot of times and in different ways to pass a string from one activity (LoginActivity) to another one (SettingsActivity). Of course I did a lot of research and tried each provided solution, but nothing could help me until now

}
});

return true;
}

}
return super.onOptionsItemSelected(item);
}
#Override
public void onClick(View view) {
HashMap postData = new HashMap();
String username = etUsername.getText().toString();

startActivity(intent);
} else {
Toast.makeText(LoginActivity.this, "Wrong username or password. Please register and try again.", Toast.LENGTH_LONG).show();
}
}
});
task1.execute("http://192.168.0.11/customer/");
visitactivity1();
}
public void visitactivity1() {
Intent i = new Intent(LoginActivity.this, SettingsActivity.class);
Bundle bundle = new Bundle();
bundle.putString("key", etUsername.getText().toString());
i.putExtras(bundle);
startActivity(i);
finish();
}
}
SettingsActivity.class:
package com.naderk.pds;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
TextView textView = (TextView) findViewById(R.id.tvUserName);
Bundle bundle = getIntent().getExtras();
String stuff = bundle.getString("key");
textView.setText(stuff);
}
}
Logcat:
Exceeds 30.000 characters lol
I really hope that someone is able to help me.
Cheers!

Try this
public void visitactivity1() {
Intent i = new Intent(LoginActivity.this, SettingsActivity.class);
i.putExtra("key", etUsername.getText().toString());
startActivity(i);
finish();
}
and on the second activity
public class SettingsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
TextView textView = (TextView) findViewById(R.id.tvUserName);
String stuff = getIntent().getStringExtra("key");
textView.setText(stuff);
}
}
Hope it helps (:

You can add the putExtras
if(s.contains("success")){
Toast.makeText(LoginActivity.this, "Login successful", Toast.LENGTH_LONG).show();
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
intent.putExtra("passwordText", password.getText().toString());
intent.putExtra("usernameText",username.getText().toString());
startActivity(intent);
On your second activity implement the following within your onCreate() method
Intent intent = getIntent();
String password = intent.getStringExtra("passwordText");
String username = intent.getSringExtra("usernameText");
You can read this blog for more information about intents : What are intents
In summary is a tutorial about how to implement intents. It may help you in case you want to change your structure.
Finally, I´m not sure if this is the way you wanted to pass the data : instead use it as I recommend. I hope it helps !
postData.put("txtUsername", username);
postData.put("txtPassword", password);

You can use Bundle methods to to send and receive Strings across your Activity class.

Delay actions in android until a previous action has completed

The app I'm working on prompts for the user to log in using Firebase when the app is opened. If the app is completely closed, then upon opening it will take the user to the login screen. However, many of the workers at the company where I work don't close the app, they just send it to the background. That's a problem, because if I delete their account, it doesn't kick them out instantly; it only kicks them out once they close the app.
To fix this, I essentially coded the home screen such that every time the page reloads-whether coming to the foreground, returning home from a different activity, or starting up the app again-it logs the user out in the background, then re-logs them in, at which point it checks the validity of their user account.
The end goal of this is that if the user still has a valid login, they will be unaffected, but if they have an invalid login, they'll get locked out even if they haven't fully shut down the app.
However, currently the app kicks the user back to the login screen even with a valid login already entered.

Suggestions would be appreciated.

In the Home_Screen activity, I think you would get better results if you added a completion listener to signInWithEmailAndPassword(), similar to what you have in your MainActivity.
With the existing code:
mAuth.signInWithEmailAndPassword(prefs.getString("username", ""), prefs.getString("password", ""));
user = FirebaseAuth.getInstance().getCurrentUser();
if(user != null){
//all good
}
you are requesting the current user before the sign-in has completed, so user is null.
Add the completion listener and move the code to generate the toast and start MainActivity there, running it when task.isSuccessful() is false.
Also, instead of using sign-out/sign-in to test whether the user account is still valid, you might want to experiment with FirebaseUser.reload(). The documentation indicates it returns a failure result if the current user account is disabled or deleted.
Use a completion listener to get the reload() status:
user.reload().addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
// account is still valid
} else {
// account is no longer valid
}
}
});

Android code does not update user account

I am working on an android code and trying to update the user information. I am able to retrieve the information but have not been able to update. Not sure what I am doing wrong.
In the if-else statement, it does not hit the If statement, goes directly to the error(else statement.
here is the code
package com.example.autrui;
import com.parse.GetCallback;
import com.parse.ParseACL;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import com.parse.ParseUser;
import com.parse.SaveCallback;
import com.parse.SendCallback;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class EditPP extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.editpp);
final Button confirmChangeEditPP = (Button) findViewById(R.id.bconfirmChangeEditPP);
final EditText fullName = (EditText) findViewById(R.id.etFullName);
final EditText email = (EditText) findViewById(R.id.etEmail);
//final ParseUser currentUser = new ParseUser();
final ParseUser currentUser = ParseUser.getCurrentUser();
System.out.println(currentUser);
String objectId = currentUser.getObjectId();
System.out.println(objectId);
String fName = currentUser.getString("fullName");
fullName.setText(fName);
email.setText(currentUser.getString("email"));
ParseQuery<ParseObject> userQuery = ParseQuery.getQuery("User");
userQuery.getInBackground((String)objectId, new GetCallback<ParseObject>(){
public void done(final ParseObject object, ParseException e) {
if (e == null) {
confirmChangeEditPP.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ParseACL acl = new ParseACL();
acl.setPublicReadAccess(true);
acl.setPublicWriteAccess(true);
currentUser.setACL(acl);
object.put("fullName", fullName.getText().toString());
object.put("email", email.getText().toString());
object.saveInBackground();
}
});
} else {
Log.e("error","error");
}
}
});
}
#Override
public void onBackPressed() {
finish();
// Go to settings
/*
* if(MainActivity.s.isEmpty()) return; else { View v =
* MainActivity.s.pop(); Class c = MainActivity.s2.pop(); Intent intent
* = new Intent(v.getContext(), c); startActivityForResult(intent, 0); }
*/
}
private void showUserDetailsActivity() {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
}

I got the answer. the error was regarding the ACL and yes we did not need the query. I wrote the whole code again and made it simpler.
