Solutions

1. Pass a non-null PatchListener implementation to Builder.listener().
2. Guard the call: only call Builder.listener(listener) after verifying listener != null.

When it happens

Trigger: Thrown at tinker-android/tinker-android-lib-no-op/src/main/java/com/tencent/tinker/lib/tinker/Tinker.java:357 when the library encounters an invalid state.

Common situations: Thrown from Tinker.Builder.listener() when the supplied PatchListener is null. Usually caused by a listener field that was never initialized before Tinker installation.
