GDA(GJoy Dex Analysizer) Most reverse engineers mainly use Java decompiler, commercial Dalvik decompiler Jeb, and smali2java to analyze Android APPs. Java decompiler is based on Java bytecode, including JD, JD-GUI, jadx, and others. smali2java is a decompiler based on the Smali code. They have their own shortcomings, such as the Java decompiler depends on the convert of dex2jar. For complex, obfuscated or packed apks, there is a problem of translation failure. smali2java decompiles Smali code which should be translated from DEX with apktool, so it increases the difficulty and error rate, and decreases the speed of manual analysis. In addition, their interaction is poor, which increases the difficulty of manual analysis. Although the commercial Jeb has better interactivity, it is easy to death when analyzing a large-sized APP with the Multidex, and it is very expensive for me… Changelog v3.97 A lot of novel optimizations and some updates have been added, and A lot of bugs have been fixed. In particular, the loading and analysis speed has been increased 3+ times faster than the old one. Double-clicking an interface method in an interface class, all implementations of the interface method will be displayed The memory limit is broken through and some problems caused by it is fixed Resource parsing and decompilation of resource classes are added The associated function of the permission module is disabled by default and can be enabled through the menu > View > PermissionRef The loading and parsing algorithms of classes, methods in the file are greatly optimized. DX tool is integrated into GDA. Optimizing the color configuration manager. Optimizing the Deobfuscation(much faster than the old) and fixing several bugs Loading analysis timeout prompt is added. The conversion of 64-bit integer data among with hexadecimal, hexadecimal, octal, character is added, and fix the problem that negative numbers cannot be converted correctly. The traversal algorithms of AllStrings and AppStringsare optimized to greatly improve the parsing speed. Add native methods and interfaces traversal function(pro). Optimize the display of callgraph of classes and methods. Resource file sensitive information detection is added to SensitiveInfo(pro). Optimize the search speed of string cross-reference.
