Firebase client libraries silently import and enable Google Analytics in apps [0]. Then your app silently sends a lot of user behavior data to Google [1]. Android apps which use push notifications must use the Firebase Cloud Messaging library. I think many app developers don't realize that adding that library also adds and enables analytics. For example, adding the `firebase_messaging` module [2] to a Flutter app causes the Android build to import [3] the `com.google.firebase:firebase-bom` Java dep which includes `firebase-analytics` [4]. Once the Java library is included in the build, it starts working automatically [0]. To disable Google Analytics in an app: * Firebase > Docs > Engage > Configure Analytics Data Collection and Usage [5] * dart > firebase_analytics > FirebaseAnalytics > setAnalyticsCollectionEnabled method [6] * Be sure to check the logs to make sure your change took effect. See "Firebase Google Group > Disabling analytics for iOS has no effect?"
