Module dex 

Minimal ZIP + DEX parser for reading TRANSACTION_* static int field values from framework.jar without any subprocess or external tool.

Only handles STORED (uncompressed) DEX entries. Android framework JARs store DEX uncompressed so ART can mmap directly from the ZIP.

Functions

find_transaction_code

Search framework.jar for the value of a static int field.

resolve_tx_codes_from_dex

Resolve all four tx codes needed for binder observer mode.
