Okta oidc android lib throwing error for Android api levels < 24

Error message: Fatal Exception: java.lang.NoSuchMethodError
No static method stream([Ljava/lang/Object;)Ljava/util/stream/Stream; in class Ljava/util/Arrays; or its super classes (declaration of ‘java.util.Arrays’ appears in /system/framework/core-libart.jar)

File: https://github.com/okta/okta-sdk-java/blob/master/impl/src/main/java/com/okta/sdk/impl/config/DefaultEnvVarNameConverter.java

Okta oidc android is internally using okta-sdk-java to implement sessionToken flow. Above file is using Arrays.stream method on line 46. This line is failing on marshmellow and lollipop (java 7 sdk). Is there any way to fix this.

The okta-sdk-java uses Java8 features that are not supported on API < 24. For these devices you can try using the bazel libraries. https://github.com/okta/okta-oidc-android/tree/authn_android
