React-native-push-notification: Firebase Cloud Messaging Cannot invoke method get() on null object

[guitar9]

When i want to react-native run-android i get this error

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApk'.
   > A problem occurred configuring project ':react-native-push-notification'.
      > Cannot invoke method get() on null object

I am using firebase cloud messaging... Or is that not a good idea? I just want to send Push Notifications from my backend to the app.

When i did these steps descriped in firebase. I get the errror

(<project>/build.gradle):
buildscript {
  dependencies {
    // Add this line
    classpath 'com.google.gms:google-services:4.0.0'
  }
}
(<project>/<app-module>/build.gradle):
dependencies {
  // Add this line
  compile 'com.google.firebase:firebase-core:16.0.0'
}
...
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

I tried to open it with android studio but there i get the same error message

somebody tried out https://github.com/evollu/react-native-fcm with android?

Did you use the package from git or from npm ? Npm version isn't updated.

heyyy
(/build.gradle):
buildscript {
dependencies {
// Add this line
classpath 'com.google.gms:google-services:+'
}
}
(//build.gradle):
dependencies {
// Add this line
compile 'com.google.firebase:firebase-core:+'
}
...
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

it's use like this it's work fine

This error goes away if I modify build.gradle in both my main app, as well as react-native-push-notification's project.

I also need google-services.json in both of the projects.

However, that means I need one json to use my package name, and the other json has to use 'com.dieam.reactnativepushnotification'. In the end, this seems to confuse Firebase, and I receive no notification.

[Gp2mv3]

@githubandrewd can you elaborate more ?
Can Issue #796 be linked to yours ?

[effortlesscoding]

@Gp2mv3 Thanks for the suggestion. #796 does not seem to be my problem. The get() on null object error happens during the compilation time.

What I do is:
1) I link react native push notifications, update Manifest, gradle files in my main project.
2) I try to build the project, and I get the error

Cannot invoke method get() on null object

The error goes away and I am able to compile it properly if I do the same gradle files fixes in react-native-push-notifications. However, that doesn't feel right.

I was running everything in Android Studio 3.1.3`, react-native 0.56.0 .

I don't have code samples anymore, unfortunately.

[onusgit]

@Gp2mv3 any workaround yet? i got same problem?
install this lib, follow firebase setup steps, add google_service.json file, even change react-native-push-notification lib's gradle file.. still getting this error..

as per @githubandrewd comment -> I also need google-services.json in both of the projects.
how can we add google-service .json for your project too?

[onusgit]

In my android studio logs.. i get error like this
