google-services json for different productFlavors

Question

Update  GCM is deprecated  use FCM   I m implementing the new Google Cloud Messaging following the guides from the Google Developers page here  I ve successfully run and test it  But my problem now is I have different product flavors with different applicationId packageName and different Google Cloud Messaging Project Id  The google-services json have to be put at the  app google-services json not the flavors folder   Is there any way to make the google-services json config different for many flavors

google-services json file is unnecessary to receive notifications  Just add a variable for each flavour in your build gradle file   buildConfigField  String    GCM SENDER ID      111111111111      Use this variable BuildConfig GCM SENDER ID instead of getString R string gcm defaultSenderId  while registering   instanceID getToken BuildConfig GCM SENDER ID  GoogleCloudMessaging INSTANCE ID SCOPE  null

Wrote a Medium post on this issue   Had the a similar problem  using BuildTypes instead of Flavors   and fixed it like so    Take advantage of Gradle s dependency management system  I created two tasks  switchToDebug and switchToRelease  Require that any time assembleRelease is run  that switchToRelease is also run  Same for debug   def appModuleRootFolder       def srcDir    src  def googleServicesJson    google-services json   task switchToDebug type  Copy        def buildType    debug      description    Switches to DEBUG google-services json      from    srcDir    buildType       include   googleServicesJson      into   appModuleRootFolder     task switchToRelease type  Copy        def buildType    release      description    Switches to RELEASE google-services json      from    srcDir    buildType        include   googleServicesJson      into   appModuleRootFolder     afterEvaluate       processDebugGoogleServices dependsOn switchToDebug     processReleaseGoogleServices dependsOn switchToRelease     EDIT  use processDebugFlavorGoogleServices processReleaseFlavorGoogleServices task to modify it at a per-flavor level

We have a different package name for debug builds    debug  so I wanted something that works based on flavor and buildType  without having to write anything flavor-related in the pattern of processDebugFlavorGoogleServices    I created a folder named  google-services  in each flavor  containing both the debug version and the release version of the json file       In the buildTypes section of your gradle file  add this         applicationVariants all   variant - gt              def buildTypeName   variant buildType name             def flavorName   variant productFlavors 0  name               def googleServicesJson    google-services json              def originalPath    src  flavorName google-services  buildTypeName  googleServicesJson              def destPath                    copy                   if  flavorName equals getCurrentFlavor     amp  amp  buildTypeName equals getCurrentBuildType                           println originalPath                     from originalPath                     println destPath                     into destPath                                         It will copy the right json file at the root of your app module automatically when you ll switch build variant   Add the two methods called to get the current flavor and current build type at the root of your build gradle   def getCurrentFlavor         Gradle gradle   getGradle       String  tskReqStr   gradle getStartParameter   getTaskRequests   toString        Pattern pattern       if  tskReqStr contains   assemble              pattern   Pattern compile  assemble   w   Release Debug        else         pattern   Pattern compile  generate   w   Release Debug         Matcher matcher   pattern matcher  tskReqStr        if  matcher find               println matcher group 1  toLowerCase           return matcher group 1  toLowerCase             else               println  NO MATCH FOUND          return              def getCurrentBuildType         Gradle gradle   getGradle       String  tskReqStr   gradle getStartParameter   getTaskRequests   toString            if  tskReqStr contains  Release                  println  getCurrentBuildType release              return  release                    else if  tskReqStr contains  Debug                  println  getCurrentBuildType debug              return  debug                 println  NO MATCH FOUND      return         That s it  you don t have to worry about removing adding modifying flavors from your gradle file  and it get the debug or the release google-services json automatically

Indeed  juste one google-services json in MyApp app  directory is good  no need for aditional script with com google gms google-services 3 0 0  But be careful to delete the file google-services json from the app directory MyApp app src flavor1 res  to avoid the error type Execution failed for task   app processDebugGoogleServices    gt  No matching client found for package

I m currently using two GCM Project Id in the same app package  I put the google-service json of my first GCM project but I switch from the first to the second one only changing the SENDER ID       String token   instanceID getToken SENDER ID GoogleCloudMessaging INSTANCE ID SCOPE  null      At this point I think that the google-services json isn t mandatory

According to ahmed khan 89 s answer  you can put you  copy code  inside product flavors   productFlavors       staging           applicationId    com demo staging           println  Using Staging google-service json          copy               from  src staging               include    json              into                         production           applicationId    com demo production           println  Using Production google-service json          copy               from  src production               include    json              into                         Then you don t have to switch settings manually

Place your  google-services json  file under app src flavors respectively then in build gradle of app  under android add below code  gradle taskGraph beforeTask   Task task - gt          if  task name      process  GoogleServices                 android applicationVariants all   variant - gt                  if  task name        i process  variant name GoogleServices                         copy                           from   src   variant flavorName                           into                             include  google-services json

I have found that the google-services plugin is quite useless for projects that want to add GCM  It only generates the following file which simply adds your project ID as a string resource    lt  xml version  1 0  encoding  utf-8   gt   lt resources gt       lt  -- Your API key would be on the following line -- gt       lt string name  gcm defaultSenderId  gt 111111111111 lt  string gt   lt  resources gt    It appears that you only need it if you copied the sample code verbatim directly from the Cloud Messaging for Android guide  Here is the example line   String token   instanceID getToken getString R string gcm defaultSenderId                GoogleCloudMessaging INSTANCE ID SCOPE  null     Solution  If you want to be able to switch API projects for different build types or product flavors you can just define your own constants and choose the appropriate one when calling the getToken   API   private static final String SENDER ID    111111111111   private static final String SANDBOX SENDER ID    222222222222    String token   instanceID getToken          BuildConfig DEBUG   SENDER ID   SANDBOX SENDER ID          GoogleCloudMessaging INSTANCE ID SCOPE          null     For Product Flavors  The above code works for switching between debug and release builds  For product flavors you would define different API keys in a java source file and place the files in their corresponding product flavor directory  For reference  Gradle Build Variants

Well I am running into the same problem and couldn t get any perfect solution  It s just a workaround  I am wondering how Google didn t think about flavors     And i hope they will propose soon a better solution   What I am doing   I have two flavors  in each one I put the corresponding google-services json   src flavor1 google-services json and src flavor2 google-services json    Then in build gradle I copy the file depending on the flavor to the app  directory   android       set build flavor here to get the right gcm configuration    def myFlavor    flavor1  def myFlavor    flavor2   if  myFlavor equals  flavor1          println  -- gt  flavor1 copy       copy           from  src flavor1           include    json          into             else       println  -- gt  flavor2 copy       copy           from  src flavor2           include    json          into                 other stuff     Limitation  you will have to change myFlavor manually in gradle each time you want to run for a different flavor  because it s hardcoded    I tried many ways to get the current build flavor like afterEvaluate close    couldn t get any better solution until now   Update  Another solution  one google-services json for all the flavors   You can also  have different package names for each flavor and then in the google developer console you don t have to create two different apps for each flavor  but just two different clients in the same app  Then you will have only one google-services json that contains your both clients  Of course  this depends on how you re implementing the backend of your flavors  If they re not separated then this solution will not help you

Simplifying what  Scotti said  You need to create Multiples apps with different package name for a particular Project depending on the product flavor   Suppose your Project is ABC having different product flavors X Y where X has a package name com x and Y has a package name com y then in the firebase console you need to create a project ABC in which you need to create 2 apps with the package names com x and com y  Then you need to download the google-services json file in which there will be 2 client-info objects which will contain those pacakges and you will be good to go   Snippet of the json would be something like this       client                  client info              android client info                package name    com x                          client info              android client info                package name    com y

So if you want to programmatically copy google-services json file from all your variants into your root folder  When you switch to a specific variant here s a solution for you   android     applicationVariants all   variant - gt      copy           println  Switches to  variant google-services json          from  src  variant          include  google-services json          into                   There s a caveat to this approach that is you need to have google-service json file in each of your variants folder here s an example

Firebase now supports multiple application ids with one google-services json file   This blog post describes it in detail   You ll create one parent project in Firebase that you ll use for all of your variants   You then create separate Android applications in Firebase under that project for each application id that you have     When you created all of your variants  you can download a google-services json that supports all of your applications ids   When it s relevant to see the data separately  i e  Crash Reporting  you can toggle that with a dropdown

Inspired by  ahmed khan 89 answer above  We can directly keep like this in gradle file   android      set build flavor here to get the right Google-services configuration Google Analytics       def currentFlavor    free    This should match with Build Variant selection  free paidFull paidBasic      println  -- gt   currentFlavor copy       copy           from  src  currentFlavor           include  google-services json          into             other stuff

You have many flavor  so it mean you will have many difference package id  right  So  just go to the page where you setup generate your json file and config for each package name  All of it will add to json file   I m verry lazy to post picture now  but basically    go to https   developers google com mobile add select platform select your app IMPORTANT  type your flavor package name to field  android package name      continue to get your configuration file  Download it    When config the file  you can see that google show you the Server API Key   Sender ID  And it is same for all package  flavors   At the end  you just need only one json file for all flavors   One more question here that you have to test when you register to get Registration Token  check if is difference for each flavor  I don t touch on it but it think it should be difference  Too late now and i so sleepy    Hope it help

The point of the google-services plugin is to simplify integration of Google features   Since it only generates android-resources from the google-services json file  over-complicated gradle-logic negates this point  I think   So if the Google-docs don   t say which resources are needed for specific Google-features  I would suggest to generate the JSON-file for each relevant buildtype flavor  see what resources get generated by the plugin and then put those resources manually into their respective src buildtypeORflavor res directories   Delete the references to google-services plugin and the JSON-file after that  and you are done   For detailed information about the inner workings of google-services gradle-plugin see my other answer   https   stackoverflow com a 33083898 433421

UPDATE  The following explanation is for one Android Studio project  with one Firebase Project and different Firebase Apps inside that project  If the aim is to have different JSON files for different Firebase Apps in different Firebase Projects inside the same Android Studio project   or if you don t know what s the difference  look here    You need one Firebase App per Android Application ID  usually package name   Is common to have one Application ID per Gradle build variant  This is gonna be likely if you use Gradle build types and Gradle build flavours     As of Google Services 3 0 and using Firebase it s not necessary to create different files for different flavours  Creating different files for different flavours can be not clear or straightforward in case you have productFlavours and Build types which compose with each other   In the same file you ll have the all the configurations you need for all your build types and flavours   In the Firebase console you need to add one app per package name  Imagine that you have 2 flavours  dev and live  and 2 build types  debug and release   Depending on your config but it s likely that you have 4 different package names like    com stackoverflow example  live - release  com stackoverflow example dev  live - dev  com stackoverflow example debug  debug - release  com stackoverflow example dev debug  debug - dev    You need 4 different Android Apps in the Firebase Console   On each one you need to add the SHA-1 for debug and live for each computer you are using   When you download the google-services json file  actually it doesn t really matter from what app you download it  all of them contain the same info related to all your apps   Now you need to locate this file in app level  app       If you open that file you ll see that if contains all the information for all your package names   A pain point use to be the plugin  In order to get it working you need to locate the plugin at the bottom of your file  So this line    apply plugin   com google gms google-services       needs to be on the bottom of your app build gradle file   For most of the said here  it applies to previous versions as well  I ve never had different files for different configs  but now with the Firebase console is easier because they provide one single file with everything you need for all you configs    Firebase Docs Firebase Cloud Messaging Firebase Console

According to Firebase docs you can also use string resources instead of google-services json       Because this provider is just reading resources with known names  another option is to add the string resources directly to your app instead of using the Google Services gradle plugin  You can do this by          Removing the google-services plugin from your root build gradle   Deleting the google-services json from your project   Adding the string resources directly   Deleting apply plugin   com google gms google-services  from your app build gradle      Example strings xml    lt string name  google client id  gt XXXXXXXXX apps googleusercontent com lt  string gt   lt string name  default web client id  gt XXXX-XXXXXX apps googleusercontent com lt  string gt   lt string name  gcm defaultSenderId  gt XXXXXX lt  string gt   lt string name  google api key  gt AIzaXXXXXX lt  string gt   lt string name  google app id  gt 1 XXXXXX android XXXXX lt  string gt   lt string name  google crash reporting api key  gt AIzaXXXXXXX lt  string gt   lt string name  project id  gt XXXXXXX lt  string gt

No need for any additional gradle scripting   Google started adding different package name in the name of  android client info   It looks like below in google-services json   android client info            package name    com android app companion dev          so  following steps are enough to have different google-services json selection    Have 2 flavours Add a new dev flavour s package to google analystics configuration page and download google-services json  Notice in the new configuration file  both of your flavour s package ids are there Prepare any of your flavour build    That is it

[android] google-services.json for different productFlavors
