This is likely due to an incorrect service loader specified somewhere.

If you are unable to fix the server loader spec, you can add a -dontwarn rule for the class to silence the error using:

-dontwarn com.google.protobuf.java_com_google_android_gmscore_sdk_target_granule__proguard_group_gtm_N1281923064GeneratedExtensionRegistryLite$Loader

A discussion of a similar situation can be found in b/279996549

Could you see which service file the class is declared in? You will need to look for the class referenced META-INF/services/<somefile>.

Alternatively you can create a compiler input dump and attach in public here or privately with zerny@google.com and/or mkroghj@google.com and we can find the service info in that.
