Closing the app when user cancels immediate in app update

Currently i'm implementing the in app update feature from android. I'm using the immediate update method, the problem that I'm facing is that when the UI prompting the user to update shows and the user does not click the update button instead they click the cross button. The UI for the app update just closes and user can continue using the app.
What I want is that when user click the cross button the app immediately closes, until user updates the app then they can use the app as usual. I also uses the java code for the android development.
public class LoginActivity extends AppCompatActivity {
private LoginViewModel loginViewModel;
public static final String MyPREFERENCES = "LoginPrefs" ;
public static final String Name = "nameKey";
public static final String User = "userKey";

The image I borrowed from google, on the left image as can be seen there is a cross button on top right user can click to close the update process

The most important point I will emphasize is that you should not force users to update the app until it is absolutely necessary (like some security issues etc). Forcing updates to users is considered a very bad user experience.
To the question you asked, you have the answer in your question itself. If you check the code you have something like this in your onActivityResult method-
if (requestCode == RC_APP_UPDATE) {
//when user clicks update button
if (resultCode == RESULT_OK) {
Toast.makeText(LoginActivity.this, "App download starts...", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
//if you want to request the update again just call checkUpdate()
Toast.makeText(LoginActivity.this, "App download canceled.", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_IN_APP_UPDATE_FAILED) {
Toast.makeText(LoginActivity.this, "App download failed.", Toast.LENGTH_LONG).show();
}
}
In case when the user cancels resultCode == RESULT_CANCELED or the update fails resultCode == RESULT_IN_APP_UPDATE_FAILED, you can take whatever action you want. You can finish the activity or whatever is suitable in your situation.

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.

// Define your preferences key
private static final String USER_PHONE = "9876543210";
private static final String USER_PASSWORD = "12345";
public AppPreferences(Context context)
{
this.context = context;
sharedPreferences = this.context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
if (sharedPreferences != null)
{

}
}
//Store user PhoneId
public void setUserPhoneId(String userId){

editor.commit();
} catch (Exception e) {

}
}
// Get userPhoneId

} 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!

Video and audio call 2 Android devices - webrtc

I'm trying do develop Android app which will send audio and video via webrtc protocol between devices. This code works well with Android and web interface, but not between two Androids. Every time connection is opened and popup says that devices are connected, but there is no sound and picture. I tried a lot of things, but nothing helped. Dependencies and permissions are ok. Used my own pub and sub keys from PubNub. It opens connection 1 of 20 times between two Androids, so I think that something isn't working well here.
Followed this tutorial to create app: tutorial

I will appreciate any help. Thanks to everybody.

when You run your application that time they ask sign in usename
that time you wrote your name
put that name in VideoChatActivity class
this.pnRTCClient.listenOn("your name when your wrote at signin time");

I am not getting any exception/error in above code, but it also doesn't post my custom message on my facebook wall. It just opens an fb application and loading alert over that, nothing else. When I debug that, it neither reach on thread's run() method of postMessageOnWall() , nor I get any response defined in same method.
Please guide me where I am wrong. I know I write my whole code related to facebook post in single activity, but it just an test application. Once it is successful, I will segregate the logic.

among hundreds of things badly wrong with this example, you are not starting the thread (by calling start). If you had actually tried to make a small, self-contained example, as you should have, you would have found out on your own.

You have to save the access token of logged user for maintaining Session for further task.
according to your code following code will give you currently logged in user's access token.
String access_token = Const.fb.getAccessToken();
