Including "implementation 'com.google.firebase:firebase-analytics:17.4.4'" causes app to crash at startup every time

Question

Here is the Logcat:

Commenting out this line in the app/build.gradle

//    implementation 'com.google.firebase:firebase-analytics:17.4.4'

causes the problem to go away and the app starts normally.

Does

"AndroidRuntime: FATAL EXCEPTION: ScionFrontendApi"

mean anything to anyone?

How about this: 'java.lang.NoSuchFieldError: No static field PREFER_LOCAL of type Lcom/google/android/gms/dynamite/DynamiteModule$VersionPolicy; in class Lcom/google/android/gms/dynamite/DynamiteModule'?

 Thank you.

Answer 1

Appears to be from FirebaseAnalytics (FlutterFire) and some version conflicts. Only happened on release builds. This comment had the answer.

Locking in the Firebase versions in pubspec.yaml worked for me.

  firebase_core: 1.13.1 
  firebase_messaging: 11.2.11
  firebase_analytics: 9.1.0

Answer 2

Did you follow the steps in adding the firebase-analytics dependency as the docs guide ?

as it look like some missing attributes in an inner module.

edit: Lowering the version of the firebase-analytics dependency to a older version (17.3.0) took care of the error.

Answer 3

Just remove/comment this line in the app/build.gradle will fix the issue

implementation "com.google.firebase:firebase-analytics-ktx"

Looks like dependency issues in the firebase-analytics.

Answer 4

For me adding the following lines to proguard rules seems to have fixed it.

-keep class com.google.android.gms.** { *; }
-keep class com.google.firebase.** { *; }
