I had the same problem. This is my solution. I hope you will understand.
Situation: How to solve this problem when there is an error code '16:', stuck at the 'Sign In with Google', after we pressed our email at the messagebox not next activity appear but only appear the error.
5.2. To solve this:
5.2.1. Get SHA1 from your project (Android Studio)
5.2.2. Create the API Key and OAuth 2.0 client IDs (Android type). (https://console.cloud.google.com/apis/credentials)
5.2.3. So, the data is set at Google, so get the new Firebase Console google.json at https://console.firebase.google.com/ (at Project Settings). Download it then replace.
5.2.4. Close the Android Studio, open back, then 'Make Project'
5.2.5. Run at the phone. Success!
Refer to this link: google signIn not working in release mode apk android
Extra about google api: https://developers.google.com/maps/documentation/android-sdk/config
(adding extra things for the manifest.xml)

I was also seeing "error code 16" when integrating Google SignIn on Android with Firebase. Still not sure what I was missing but I went back to the beginning and followed this doc:
https://firebase.google.com/docs/auth/android/google-signin
This link is pretty complete. I didn't need to configure anything in Google Cloud console. I did use the info on the Integrating Google SignIn page that the above page links to and got the code and layout for the button.

After struggling for about 48 hrs to solve the firebase google sign-in error 16 credential not matching;
The only thing that solved my problem is to get your web_client_id using "Configure a Google API Console project" through this link https://developers.google.com/identity/sign-in/android/start-integrating#configure_a_project, you should provide the application id from AndroidManifest.xml and sha1 from the signingReport of android studio.
Also, I got different sha1 for each android studio project as to avoid any conflicts in firebase, this by setting debug parameters in signingConfigs {} in android {} in the app build.gradle as follow
android {
signingConfigs {
debug {
storeFile file("path_to_keystore.jks")
storePassword "keystore_password"
keyAlias "key_alias_name"
keyPassword "key_password"
}
}
}
Moreover, I recommend to try firstly google sign in without firebase to give you a positive energy, then secondly go for firebase google sign-in as needed.
Hope this helps every developer facing the same error and save their time.

Unable to write to Firebase Database from my Android application

This is the code I use to connect and write to the database (I want to create a new child node userand assign the value alex to it.
DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
mDatabase.child("user").setValue("alex");
Note: I have followed the correct set-up instructions and have changed the authorisation of read and write to true. The code was working for about a month but now I can't figure out why its not writing to the database.

What am I doing wrong, my firebase database still shows null. However when I add data manually and read via JS it is working correctly.

The errors tell you that you haven't linked Firebase to your project.

Use the Firebase Assistant to set it up:
To open the Firebase Assistant in Android Studio:
Click Tools > Firebase to open the Assistant window.
Click to expand one of the listed features (for example, Analytics), then click the provided tutorial link (for example, Log an Analytics event).
Click the Connect to Firebase button to connect to Firebase and add the necessary code to your app.

Android - I cannot choose a method in Fragment - firebase [duplicate]

This question already has an answer here:
NullPointerException when setting TextView via ButtonClick
(1 answer)
Closed 5 years ago.
I have one activity and a few fragments. My structure looks like this:
Main Activity ->
- Menu 1 Fragment-> Daily Fragment / Weekly Fragment / Monthly Fragment / Annual Fragment
- Menu 2 Fragment -> empty
- Menu 3 Fragment -> empty
All menus are fragments.
Now I want to add values to the database (Cloud Firebase), but I can not call the method (onClick).
I did OnClickListener, and Override onClick (View v). It still does not work. What else do I need?
Daily Fragment:
public class DailyFragment extends Fragment implements
View.OnClickListener{
private static final String QUOTE_KEY = "quote";
private static final String AUTHOR_KEY = "author";
private static final String TAG= "InspiringQuote";
private DocumentReference mDocRef = FirebaseFirestore.getInstance().document("sampleData/inspirations");
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
//just change the fragment_weekly
//with the fragment you want to inflate
//like if the class is DailyFragment it should have R.layout.home_fragment
//if it is WeeklyFragment it should have R.layout.fragment_weekly
//return inflater.inflate(R.layout.fragment_daily, null);
View layout = inflater.inflate(R.layout.fragment_daily, container, false);
//Dołączamy do przycisku obiekt nasłuchujący
Button saveButton = (Button)layout.findViewById(R.id.bn_save);
saveButton.setOnClickListener(this);
return layout;
}
#Override
public void onClick(View v){
switch (v.getId()) {
case R.id.bn_save:
saveQuote(v);
break;
}
}
public void saveQuote (View view){
EditText quoteView = (EditText) view.findViewById(R.id.quote);
EditText authorView = (EditText) view.findViewById(R.id.author);
String quoteText = quoteView.getText().toString();
String authorText = authorView.getText().toString();
if (quoteText.isEmpty() || authorText.isEmpty()) { return; }
Map<String, Object> dataToSave = new HashMap<String, Object>();
dataToSave.put(QUOTE_KEY, quoteText);
dataToSave.put(AUTHOR_KEY, quoteText);
mDocRef.set(dataToSave).addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG, "Dokument został zapisany!");
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w(TAG, "Błąd, dokument nie został zapisany.", e);
}
});
}}

try this way since i think when you go to your fragment it changes your view so basically you are not on the right view

Firebase (Android): Transaction.success(mutableData) causes app to crash

I'm trying to write a function to increment unread message count in a chatapp(android) using transaction in Firebase.
My database structure looks like:
The member list can in fact contain more than 2 users for a group chat which I intend to expand later.
Currently, messages can be added into the messageList but after adding to the messageList I want to increase the unreadCount for all other user except the sender as well. I realised that I need to make use of Transaction to make it atomic so this is my incrementUnreadCount code.
private static void incrementUnreadCount(String chatRoomId) {
DatabaseReference mDatabaseMemberList = mDatabaseChatRooms.child(chatRoomId).child("memberList");
mDatabaseMemberList.runTransaction(new Transaction.Handler() {
#Override
public Transaction.Result doTransaction(MutableData mutableData) {
Map<String, Map<String, Object>> tempMemberList = (Map<String, Map<String, Object>>) mutableData.getValue();
if (tempMemberList == null) {
return Transaction.abort();
}
for (String key : tempMemberList.keySet()) {
// if it is not a sender node
if (!key.equals(TutUserManager.getCurrentUid())) {
Map<String, Object> tempMap = tempMemberList.get(key);
long tempCount = (long) tempMap.get("unreadCount");
tempCount += 1;
tempMap.put("unreadCount", tempCount);
tempMemberList.put(key, tempMap);
}
}
mutableData.setValue(tempMemberList);
return Transaction.success(mutableData);
}
#Override
public void onComplete(DatabaseError databaseError, boolean b, DataSnapshot dataSnapshot) {
}
});
}
The following code works only when I send the second message. So the value of unreadCount is 1 less than what it is expected to be.
I read the doc and realised that for the null case it is supposed to be:
return Transaction.success(mutableData);
and not:
return Transaction.abort();
as abort() will make server abort the transaction instead of trying to make the transaction again.
I try to change the code above to use return ransaction.success(mutableData); but it causes the app to crash upon calling the function.
Did I miss something ?
This is what I get from the console:

In stead of iterate through each node in the Transaction thread, I use .addListenerForSingleValueEvent and iterate through each node. Then for the one that needs to be updated, I run the transaction code. This method works fine.
This is illustrated in the following code:
private static void incrementUnreadCount(String chatRoomId) {
final DatabaseReference mDatabaseMemberList = mDatabaseChatRooms.child(chatRoomId).child("memberList");
mDatabaseMemberList.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot child : dataSnapshot.getChildren()){
if(!child.getKey().equals(TutUserManager.getCurrentUid())){
mDatabaseMemberList.child(child.getKey()).runTransaction(new Transaction.Handler() {
#Override
public Transaction.Result doTransaction(MutableData mutableData) {
Map<String, Object> tempData = (Map<String, Object>) mutableData.getValue();
if(tempData == null){
return Transaction.success(mutableData);
}
long unreadCount = (long) tempData.get("unreadCount");
unreadCount += 1;
tempData.put("unreadCount", unreadCount);
mutableData.setValue(tempData);
return Transaction.success(mutableData);
}
#Override
public void onComplete(DatabaseError databaseError, boolean b, DataSnapshot dataSnapshot) {
}
});
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
