By following  Gabriel Lidenor answer  initializing app with context is not work in my case  What if you are trying to create firebase-app without google-service json   So before initializing any number of firebase app  first need to initialize as   FirebaseOptions options   new FirebaseOptions Builder   setApplicationId  APP ID                        setGcmSenderId  SENDER ID   build    FirebaseApp initializeApp context  options    DEFAULT

My problem was not resolved with this procedure  FirebaseApp initializeApp this      So I tried something else and now my firebase has been successfully initialized  Try adding following in app module gradle  BuildScript  dependencies     classpath    com google firebase firebase-plugins 1 1 5             dependencies      implementation    com google firebase firebase-perf 16 1 0  implementation    com google firebase firebase-core 16 0 3

Installed Firebase Via Android Studio Tools   Firebase     I did the installation via the built-in tools from Android Studio  following the latest docs from Firebase   This installed the basic dependencies but when I attempted to connect to the database it always gave me the error that I needed to call initialize first  even though I was      Default FirebaseApp is not initialized in this process   Make sure to   call FirebaseApp initializeApp Context  first    I was getting this error no matter what I did     Finally  after seeing a comment in one of the other answers I changed the following in my gradle from version 4 1 0 to    classpath  com google gms google-services 4 0 1    When I did that I finally saw an error that helped me      File google-services json is missing  The Google Services Plugin   cannot function without it    Searched Location     C  Users  username  AndroidStudioProjects TxtFwd app src nullnull debug google-services json   C  Users  username  AndroidStudioProjects TxtFwd app src debug nullnull google-services json   C  Users  username  AndroidStudioProjects TxtFwd app src nullnull google-services json   C  Users  username  AndroidStudioProjects TxtFwd app src debug google-services json   C  Users  username  AndroidStudioProjects TxtFwd app src nullnullDebug google-services json   C  Users  username  AndroidStudioProjects TxtFwd app google-services json   That s the problem  It seems that the 4 1 0 version doesn t give that build error for some reason -- doesn t mention that you have a missing google-services json file  I don t have the google-services json file in my app so I went out and added it   But since this was an upgrade which used an existing realtime firsbase database I had never had to generate that file in the past  I went to firebase and generated it and added it and it fixed the problem   Changed Back to 4 1 0  Once I discovered all of this then I changed the classpath variable back  to 4 1 0  and rebuilt and it crashed again with the error that it hasn t been initalized   Root Issues   Building with 4 1 0 doesn t provide you with a valid error upon precompile so you may not know what is going on  Running against 4 1 0 causes the initialization error

Another possible solution - try different Android Studio if you are using some betas  Helped for me  New Android Studio simply didn t add Firebase properly  In my case 3 3preview  After some more investigation I found the problem was that new Android studio starts project with newer Google Services version and it looks it was the original problem  As  Ammar Bukhari suggested this change helped   classpath  com google gms google-services 4 1 0  -   classpath  com google gms google-services 4 0 0

Although manually initialize Firebase with FirebaseApp initializeApp this   makes the error disappear  it doesn t fix the root cause  some odd issues come together doesn t seem to be solved  such as    FCM requires com google android c2dm permission RECEIVE permission which is only for GCM token becomes unregistered after first notification sent message not received  onMessageReceived   never get called    Use newer Gradle plugin  e g  Android plugin 2 2 3 and Gradle 2 14 1  fixed everything   Of course setup has to be correct as per Firebase documentation

In my case  the Google Services gradle plugin wasn t generating the required values xml file from the google-services json file  The Firebase library uses this generated values file to initialize itself and it appears that it doesn t throw an error if the values file can t be found  Check that the values file exists at the following location and is populated with the appropriate strings from your google-sevices json file   app build generated res google-services  build type  values values xml   and or  app build generated res google-services  flavor   build type  xml global tracker xml   For more detail see  https   developers google com android guides google-services-plugin  My particular case was caused by using a gradle tools version that was too advanced for the version of Android Studio that I was running  ie ensure you run grade tools v3 2 X-YYY with Android Studio v3 2

After updating various dependencies I got a Crashlytics error in the compile   Crashlytics found an invalid API key  null  Check the Crashlytics plugin to make sure that the application has been added successfully  Contact support fabric io for assistance   The one non-auto response I got from repeated attempts to support fabric io the error directs you to was that Fabric and Crashlytics are separate teams so they couldn t help me  I ve avoided implementing the extra Fabric layer to Crashlytics  and was unable to get a new key from the Fabric site  or even get the site to recognize me  On attempting to work around this by just removing Crashlytics from my code  I got the  Default FirebaseApp is not initialized in this process com example app  Make sure to call FirebaseApp initializeApp Context  first  crash in the run  I ve never had to add the initialization line of  FirebaseApp initializeApp this    and in fact had it commented out  The documentation even mentions not needing this if only using Firebase for one activity  Adding it made no difference  still got the run killing error  Turns out what was causing the new obscure errors was the updated google-services dependency  For now  I don t have time to spend more days trying to fix the shotgun errors the new dependency is causing  so until someone comes up with solutions I ll stick to the old version  Besides the odd initialization crash  the new version may be forcing Fabric on Crashlytics users  Users are being forced back to the old dependency version for this too  Crashlytics found an invalid API key  null  after updated com google gms google-services 4 1 0 com google gms google-services 4 1 0  BAD com google gms google-services 4 0 1  GOOD  EDIT 10 17 18  After updating the following dependencies again implementation  com google firebase firebase-ads 17 0 0  implementation  com google firebase firebase-auth 16 0 4  implementation  com google firebase firebase-database 16 0 3  implementation  com google firebase firebase-core 16 0 4  I got an immediate crash on the install attempt with  xxx has unexpectedly closed   like when I attempted the google-services dependency update  Digging into the log I found a link directing me to add this to the manifest  lt meta-data         android name  quot com google android gms ads APPLICATION ID quot          android value  quot ca-app-pub-xxxxxx xxxxxx quot   gt   This is new  and is not mentioned in the setup and interstitial instructions here https   firebase google com docs android setup and here https   developers google com admob android interstitial  I used to only have to deal with one ad-related ID for my app  the INTERSTITIAL UNIT ID  Now two need to be dealt with  Besides the above addition  documentation directs adding ADMOB APP ID here  the same number you tie with ads APPLICATION ID in the new manifest code  MobileAds initialize this  ADMOB APP ID    The INTERSTITIAL UNIT ID and ADMOB APP ID ids can be dug up in your Google AdMob console  My game app stopped serving ads on my first update of the firebase dependencies and still does not serve ads  giving error code 0 in the public void onAdFailedToLoad int errorCode       Even after all this added clutter  I still can t update the google-services dependency without the initialize error run crash  I expect to be stuck at google-services 4 0 1 for some time  EDIT 10 24 18  From mobileadssdk-advisor support google com after weeks of correspondence on not getting ad serves after updates   Thanks for sharing the device logs  From the logs  it looks like an existing issue and this is on our priority list and our team is working on the fix and this is only happening on Android O and P devices   Only O and P devices  That s the last two versions  O came out on September 25  2017  Yikes
