6494727's phone/b;->a([Ljava/lang/String;) is not working and looks like it should

whitelist methods
many Class.is*, other stuff

emulate
Ljava/lang/Class;->getMethod(Ljava/lang/String;[Ljava/lang/Class;)Ljava/lang/reflect/Method;
  return methods from any whitelisted class

getField() - emulated methods should support many Class.* methods, either as part of the interface, or inherited
if they're inherited, base class can implement all of them and return unknown values of the correct type

Ljava/lang/reflect/Method;->invoke(Ljava/lang/Object;[Ljava/lang/Object;)Ljava/lang/Object;
  invoke ourselves or run emulated method

Ljava/lang/Class;->forName(Ljava/lang/String;)Ljava/lang/Class;
  easy: return any whitelisted class
  hard: easy + do something with emulated classes

Emulate / spoof stack traces

  new-instance v1, Ljava/lang/Exception;
  invoke-direct {v1}, Ljava/lang/Exception;-><init>()V
  invoke-virtual {v1}, Ljava/lang/Exception;->getStackTrace()[Ljava/lang/StackTraceElement;

  invoke-virtual {v1}, Ljava/lang/StackTraceElement;->getMethodName()Ljava/lang/String;
  move-result-object v2
  invoke-direct {v0, v2}, Ljava/lang/StringBuffer;-><init>(Ljava/lang/String;)V
  invoke-virtual {v1}, Ljava/lang/StackTraceElement;->getClassName()Ljava/lang/String;

  invoke-static {}, Ljava/lang/Thread;->currentThread()Ljava/lang/Thread;
  move-result-object v2
  invoke-virtual {v2}, Ljava/lang/Thread;->getStackTrace()[Ljava/lang/StackTraceElement;


Hashcode? / Equals?
  ExecutionNode, Op, *State, etc.

Android class lifecycle initialization
  sometimes it can be assumed onCreate has been called
  or just give a list of methods to be called before whatever else

  java -jar simplify/build/libs/simplify-0.1.0-all.jar -i 7604399 -it 'PornApplication;->i2c1cqop3faop3cdhokggmd97ce\(\)'
  ArrayLists are initialized in onCreate, but since that's not known, everything fails


allow emulated methods to handle unknown values

two issues:
inner classes are not always resolved properly, should add tests for this, look at base64$coder
methods with arrays, like anything in 8748278, don't optimize correctly
