And also when next time user login that device pic will remain intact and shouldnt be replaced by google id pic.

Here is my MainActivity.java

import ...


public class MainActivity extends AppCompatActivity{

    private FirebaseAnalytics mFirebaseAnalytics;
    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthStateListener;
    private FirebaseDatabase database = FirebaseDatabase.getInstance();
    private DatabaseReference myRef = database.getReference();
    private TextView mName;
    private TextView mEmail;
    private String name;
    private String emailname;
    private Uri photoUrl;
    private ImageView mPic;
    private NavigationView mNavigationView;
    private static final int RC_SIGN_IN = 0;

        // Obtain the FirebaseAnalytics instance.

        //myRef.setValue("Hello World");

Suggest me way to do this. I tried on my own but failed. Thanks :)

Answer 1

Okay so i achieved this using bunch of if-else codes which i am sharing below. Inintially i set flag to 0, and when logged user tries to open the app then flag is set to 1

 public void getCurrentUserInfo() {
        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
        if (user != null) {

            for (UserInfo profile : user.getProviderData()) {
                String providerId = profile.getProviderId();
                String uid = profile.getUid();
                name = profile.getDisplayName();
                if (flag!=1) {
                    photoUrl = profile.getPhotoUrl();
                    if (photoUrl == null) {
                        Picasso.get()
                                .load(R.drawable.usericon)
                                .resize(6000, 2000)
                                .transform(new CropCircleTransformation())
                                .centerInside()
                                .into(mPic);

                    } else {
                        Picasso.get()
                                .load(photoUrl.toString())
                                .resize(6000, 2000)
                                .transform(new CropCircleTransformation())
                                .centerInside()
                                .into(mPic);

                    }
                }else{
                    DatabaseReference valueRef = myRef.child("Users").child(name);
                    valueRef.child("ProfileUrl").addListenerForSingleValueEvent(new ValueEventListener() {
                        @Override
                        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                            String url = dataSnapshot.getValue(String.class);
                            photoUrl=  Uri.parse( url );
                            if (photoUrl == null) {
                                Picasso.get()

                                        .transform(new CropCircleTransformation())
                                        .centerInside()
                                        .into(mPic);

                            } else {
                                Picasso.get()
                                        .load(photoUrl.toString())

                            }

                        }

                        @Override
                        public void onCancelled(@NonNull DatabaseError databaseError) {

                        }
                    });
                }
                emailname = profile.getEmail();
                mName.setText(name);
                mEmail.setText(emailname);
                if (name != null && emailname != null) {
                    myRef.child("Users").child(name).child("Email").setValue(emailname);
                    myRef.child("Users").child(name).child("UserId").setValue(uid);
                }
            }
        }
    }

I have posted full code in my question this is just the edited part required to initiate my query. For any queries comment.
