Missing symbols from ruby.

symbol_envy.java

package com.my.package;

static import com.my.package.Symbols.*;

class MyClass {
  // Symbol constants
  enum Symbols { EXTRA_SOME_KEY }
  
  void unpackExtras() {
    Bundle extras = getIntent().getExtras();
    
    // Explicit, three step rocket
    extras.getString(Symbols.EXTRA_SOME_KEY.name());
    
    // Using the statically imported enum
    extras.getString(EXTRA_SOME_KEY.name());
  }

}

It's a bit nasty for external usage though.

put(MyClass.Symbols.EXTRA_SOME_KEY.name(), "value");
