Reading from Firebase Database without crashing

I'm creating an app that requires me to read from a fire base database and this value to alter layouts. I've tried using the 'help' from android studio but when I run the program it crashes. The photo I've attached is the 'help' not as code because it crashed the program and I wanted it work basically. So can anyone advise an easier method of reading from the database?
Thanks

Unable to get advertising id

While running the demo (https://github.com/androidthings/doorbell) on my respberry PI, I run into error like the following:

The following is the method I tried:
I did some research and find the following relevant post:
adjust/unity_sdk#88
Following the instruction to install play service with android SDK manage tool (using android studio). Clear the project. Rebuild. Install the new apk into respberry PI but still have the same error log.
I also checked on the firebase console, no picture was updated. Even from the android monitor, it was confirmed that button was pushed camera works as expected.
Regarding internet connection, I installed another app on the raspberry PI. It successfully sent the info to the server. It confirms the connectivity works as expected.
Any suggestion?

The log message you are seeing is from FirebaseAnalytics (the "FA" in the log tag), and makes sense since analytics is not enabled in this sample (unless you added code to enable it). Notice this is also a debug message (the "D" in the log tag) and not an error/warning.
This should not be affecting the Doorbell sample, so if you are not able to get the images uploaded properly to Firebase there is likely something else wrong with the project configuration and perhaps there are other clues deeper in the log.

It turns out that configuration is not appropriate. It uses the new SDK path which doesn't install google play service. Once I switch to the default SDK path of system which installed google play service. The logs looks different event though that message "Unable to get advertising id:" is still there. It seems (from FA log) the app can talk to the server.

How to add Firebase into android

I want added Firebase into my application. I write below codes, but when running application I can't see TOKEN in log!
My dependencies :

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

'Unfortunately, app has stopped' is shown twice on the device and 'Application terminated' in android studio with no error being shown

I am developing an app using Android Studio.
The problem is that app gets crashed twice within few minutes of running it and besides Application terminated. and normal logs no error is shown in the logcat.
Here's complete logcat:

I tried integrating crashlytics but even it doesn't show any error when the app crashes in this manner.
The question is how will I be able to fix the error if I don't even know what the error is?
Please help me with this.

I think the issue is related to your ad view.
In last line it is showing that ad is not visible.

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) {
}
});
}
