Add DexTrace core-library backend (continuation of PR #855) - #958
Merged

Conversation
Replaces the silent get_apk_permissions() call with a direct parse_manifest()
call that raises ValueError when the manifest is missing or has invalid AXML
bytes. trickmo and tanglebot APKs now fail fast (< 1 s) instead of running
three full DEX passes (134 s on trickmo).
parse_manifest() requires DexTrace fix: propagate {"error": ...} from
ManifestParser instead of silently mapping it to empty fields.
Adds two unit tests for the two ValueError paths:
- invalid AXML bytes in AndroidManifest.xml
- AndroidManifest.xml entry absent from the ZIP

Description
Adds
DexTraceImpas a new concrete implementation ofBaseApkinfo, allowing Quark to use DexTrace as an alternative APK analysis backend. Activate it with--core-library dextrace:Key Changes
quark/core/dextraceapkinfo.py: AddDexTraceImp, implementing the sameBaseApkinfointerface asAndroguardImp.quark/core/quark.py:core_library="dextrace"toDexTraceImp.find_api_usagesubclass BFS: checkclass_name in current_class_setinstead of discardingLjava/lang/Object;and testing non-empty.tests/core/test_dextraceapkinfo.py: Add integration tests covering:tmp_path).Motivation and Context
DexTrace is a Python APK analysis library that parses DEX bytecode independently of the androguard package. Adding it as a backend gives Quark an alternative that does not depend on androguard. The implementation handles the anti-analysis patterns and class naming conventions seen in real-world malware samples.
