Start by reproducing the Android hotfix failure with Robust 0.4.91 and the listed Gradle versions, then inspect EnhancedRobustUtils and MainActivityPatch.onCreate at MainActivityPatch.java:30. Use the stack trace to trace the reflective call through PatchProxy and MainActivityPatchControl. Done means identifying why the patch's reflective lookup fails and confirming that the patch takes effect without the reported null-pointer errors.
