android - ConnectivityManager ClassCastException with Google Analytics v4 and ProGuard -

i'm having troubles compiling app uses proguard , google analytics v4. single other thread seems similar here, except there aren't many details.

i've tried next no avail:

doing keep com.google.** { *; } doing -keep android.support.** { *; } package. error continues crop every other bit of obfuscated code, if joining newly obfuscated code pre-obfuscated google analytics code causes errors. using -keepattributes signature in case there's issue generics. using obfuscated dictionary of four-letter words (such rnqp, sslq) in case android dexing causes pre-obfuscated google analytics classes conflict obfuscated project files.

here exception:

proguard configuration file (99.9% vanilla):

it seems you're using re-create of proguard-android-optimize.txt (a more mutual approach refer original, maintained file in android sdk). can seek disabling optimization:

-dontoptimize

if indeed avoids problem, can study issue in proguard's bug tracker or me directly.

make sure using latest version of proguard (version 5.1 @ time of writing) , latest version of gms library.
