How can I resolve App stuck on Splash Screen

Good day,
My application was working for months now, but all of a sudden it is stuck on splash screen, when using both Android Studio and the live App on Google Play. And I haven't done any change to the app of resent.
Please, anyone help?
Below is the logcat debug result. Thank you

if you didn't changed anything in your app (an we are talking even about app distributed by Google Play) then clearly there is a problem by server side
there is a chance that some network/server side response is just broken, I see you are requesting for something (RequestObject), but also see serverUrl='null', so app may not be configured properly. Also last words of this log is ConnectionBuilder: Response = and... what is the response?
there is no Exception word in block of text posted in question, so app hangs on splash because of wrong logic in code (maybe not aware of some null parameters)
there is also a chance that you are using 3rd party lib connecting to some services (I see Firebase in logs), which is currently deprecated
without line of code all this is guessing...
PS. learn how to post readable logs...

Why does my app show a black screen on launch?

So I'm getting a black screen whenever I try to run my code through android studio

you have heavy work in the main thread, it will happen to ANR (android not responding), you should check your work, and a black screen is your application theme

How can I fix this issue and show Firebase token in logs?

Firebase onTokenRefresh() will only be called if your token changes. Before that you should invoke
FirebaseInstanceId.getInstance().getToken()
in your initial activity (like MainActivity) maybe.

why you not tried integrated android studio with firebase directly using Tools menu-->firebase
add this line Gradle :-Module(app)
compile 'com.google.firebase:firebase-crash:10.2.0'
compile 'com.google.firebase:firebase-auth:10.2.0'

Try to uninstall the application and re-install , you will see the
Refreshed token in the logcat.
Also check in firebase console that Anonymous sign-in status is
Enabled or not in Authentication menu -> Sign in method

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

}
});
}
