I have a question about Firebase+Crashlytics+Android. On Android Studio I am getting the following error:
org.gradle.api.GradleException: Crashlytics Developer Tools error. com.crashlytics.tools.android.exception.PluginException: Crashlytics Developer Tools error. java.lang.illegalArgumentException: Crashlytics found an invalid API key: null.
I have followed the instructions here and here. As I understand it, I don’t need to set the apiKey in the project and Firebase will take care of this. But the project build still fails and complains. I haven’t been able to find appropriate help online about this. The documentation on Crashlytics also seems to be in beta on Firebase.
The closest I’ve gotten is someone suggesting that I set up a fabric.properties file with an apiKey field set. But on the Firebase->Crashlytics dashboard I can’t find this API key.
Does anyone have an idea how this can be resolved?
Note 1: I don’t have admin access to the project on Firebase. Maybe the key is only visible to them?
Note 2: It’s actually a react-native project. But that shouldn’t really make a difference since this is purely a native-side configuration.

Mike from Firebase here. If you are an existing Firebase customer, using Crashlytics via Fabric, then here's what your files should look like. Note: We don't have official React Native support, so I'm not including any of those files. I don't think it's relevant given the native implementation here, but trying to be clear :)
Project build.gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
maven {
url 'https://maven.fabric.io/public'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.2.0' // google-services plugin
classpath 'io.fabric.tools:gradle:1.25.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven {
url 'https://maven.google.com/'
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
App's build.gradle:

MainActivity.java:
There should be some implementation of Firebase. To keep thing simple, I'm initializing Firebase analytics:
public class MainActivity extends AppCompatActivity {
private FirebaseAnalytics mFirebaseAnalytics;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);
setContentView(R.layout.activity_main);
}
