+# NOTE: release builds enable minification (isMinifyEnabled=true in the

+# ONNX Runtime (ai.onnxruntime): the Java binding is backed by JNI. Native code
+# resolves Java methods/classes by their original names; R8 renaming or
+# stripping them causes a hard crash at runtime with no Java stack trace.
+# This rule is required by the ONNX Runtime docs for minified Android builds.
