java.lang.ExceptionInInitializerError

[EdwardQuixote]

Error is encountered in built and generated signed APKs (Issue doesn't occur on debug mode or when running App from Android Studio without generating an APK) on:
Qiscus.init(this, "MY_APP_ID");
Encountered problem in releases:

• 1.19.1

• 2.7.2

• 2.8.0

There's not so much documentation on this error relating to Qiscus. When above initialization line of code is commented out, issue isn't encountered.

Are you using proguard for release version?
Please add this rules https://github.com/qiscus/qiscus-sdk-android/blob/master/app/proguard-rules.pro to your proguard-rules.pro file.
