I'm following this manual to integrate AppsFlyer into our Android app.
When I try to build the project with minifyEnabled true the following warnings appear in the build log:
Warning: com.appsflyer.GcmInstanceIdListener: can't find superclass or interface com.google.android.gms.iid.InstanceIDListenerService
Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceID
Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceIDListenerService Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceID Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceID
Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceIDListenerService
Warning: com.appsflyer.GcmInstanceIdListener: can't find referenced class com.google.android.gms.iid.InstanceIDListenerService
Warning: com.appsflyer.u: can't find referenced class com.google.android.gms.iid.InstanceIDListenerService
And the build fails.
Here is relevant part of the app's module build.gradle:
dependencies {
implementation 'com.google.firebase:firebase-core:16.0.7'
implementation 'com.google.firebase:firebase-messaging:17.3.4'
implementation 'com.appsflyer:af-android-sdk:4+@aar'
implementation 'com.android.installreferrer:installreferrer:1.0'
}
Here is relevant part of ProGuard configuration:
-dontwarn com.android.installreferrer
Please add the following as well:
-dontwarn com.appsflyer.**
