What is Shrinking?
- Java bytecode contain a lot of unused code, especially if it includes program libraries
- Shrinking programs such as ProGuard can analyze bytecode and remove unused classes, fields, and methods.
- The program remains functionally equivalent, including the information given in exception stack traces
What is Obfuscation?
- Compiled bytecode still contains a lot of debugging information:
- source file names, line numbers, field names, method names, argument names, variable names, etc.
- This information makes it straightforward to decompile the bytecode and reverse-engineer entire programs.
